Saf

ety precautions for chain saw

users

(ANSI B175.1-2000 Anne

x C)

Kic

kback safety precautions

With a basic understanding of kic

kback, you can reduce

or eliminate the element of surprise. Sudden surprise

contributes to accidents.

Keep a good ﬁrm grip on the saw with both hands, the

right hand on the rear handle, and the left hand on the

front handle, when the engine is running. Use a ﬁrm grip

with thumbs and ﬁngers encircling the chain saw handles.

A ﬁrm grip will help you reduce kickback and maintain

control of the saw. Don’t let go.

Make sure that the area in which you are cutting is free

from obstacles. Do not let the nose of the guide bar

contact a log, branch, or any other obstacle which could

be hit while you are operating the saw.

Cut at high engine speeds.

Do not overreach or cut above shoulder height.

Follow manufacturer’s sharpening and maintenance

instructions for the saw chain.

Only use replacement bars and chains speciﬁed by the

manufacturer or the equivalent.

Other saf

ety precautions

Do not oper

ate a chain saw when you are fatigued.

Use safety footwear; snug-ﬁtting clothing, protective

gloves, and eye, hearing and head protection devices.

Use caution when handling fuel. Move the chain saw at

least 10 feet (3 m) from the fueling point before starting

the engine.

Do not allow other persons to be near the chain saw when

starting or cutting with the chain saw. Keep bystanders

and animals out of the work area.

Do not start cutting until you have a clear work area,

secure footing and a planned retreat path from the falling

tree.

Keep all parts of your body away from the saw chain when

the engine is running.

Before you start the engine, make sure that the saw chain

is not contacting anything.

Carry the chain saw with the engine stopped, the guide

bar and saw chain to the rear, and the mufﬂer away from

your body.

Do not operate a chain saw that is damaged, improperly

adjusted, or not completely and securely assembled. Be

sure that the saw chain stops moving when the throttle

control trigger is released.

Shut off the engine before setting the chain saw down.

Use extreme caution when cutting small size brush and

saplings because slender material may catch the saw

chain and be whipped toward you or pull you off balance.

When cutting a limb that is under tension be alert for

springback so that you will not be struck when the tension

in the wood ﬁbers is released.

Keep handles dry, clean and free of oil or fuel mixture.

Operate the chain saw only in well-ventilated areas.

Do not operate a chain saw in a tree unless you have

been speciﬁcally trained to do so.

Do not operate a chain saw above shoulder height.

All chain saw service, other than the items listed in the

operator’s/owner’s safety and maintenance instructions,

should be performed by competent chain saw service

personnel. (For example, if improper tools are used to

remove the ﬂywheel or if an improper tool is used to hold

the ﬂywheel in order to remove the clutch, structural

damage to the ﬂywheel could occur and subsequently

cause the ﬂywheel to burst.)

When transporting your chain saw, use the appropriate

guide bar guard.

Note: This Annex is intended primarily for the consumer or

occasional user.

!

W

ARNING! Kickback may occur when

the nose or tip of the guide bar touches

an object, or when the wood closes in

and pinches the saw chain in the cut.

Tip contact in some cases may cause a

lightning fast reverse reaction, kicking

the guide bar up and back towards the

operator.

Pinching the saw chain along the top of

the guide bar may push the guide bar

rapidly back towards the operator.

Either of these reactions may cause you

to lose control of the saw which could

result in serious personal injury.

Do not rely exclusively upon the safety

devices built into your saw. As a chain

saw user, you should take several steps

to keep your cutting jobs free from

accident or injury.

!

W

ARNING! Do not operate a chain saw

with one hand! Serious injury to the

operator, helpers, bystanders or any

combination of these persons may result

from one-handed operation. A chain saw

is intended for two-handed use.

GENERAL SAFETY PRECAUTIONS

8 – English

Always use common sense

It is not possible to cover every conceivable situation you

can face when using a chain saw. Always exercise care

and use your common sense. Avoid all situations which

you consider to be beyond your capability. If you still feel

uncertain about operating procedures after reading these

instructions, you should consult an expert before

continuing. Do not hesitate to contact your dealer or us if

you have any questions about the use of the chain saw.

We will willingly be of service and provide you with advice

as well as help you to use your chain saw both efﬁciently

and safely. Attend a training course in chain saw usage if

possible. Your dealer, forestry school or your library can

provide information about which training materials and

courses are available.

Work is constantly in progress to improve the design and

technology - improvements that increase your safety and

efﬁciency. Visit your dealer regularly to see whether you

can beneﬁt from new features that have been introduced.

Personal protective equipment

• Approved protective helmet

• Hearing protection

• Approved protective goggles and a visor. The

approved protective goggles should comply with

standard ANSI Z87.1.

• Gloves with saw protection

• Trousers with saw protection

• Boots with saw protection, steel toe-cap and non-slip

sole

• Always have a ﬁrst aid kit nearby.

• Fire Extinguisher and Shovel

Do not wear loose ﬁtting clothing, scarves, neckties,

jewelry or any item that may become tangled in

surrounding growth or the chain saw itself. Generally

clothes should be close-ﬁtting without restricting your

freedom of movement.

s safety equipment

In this section the machine’s safety features and their

function are explained. For inspection and maintenance

see instructions under the heading Checking, maintaining

and servicing chain saw safety equipment. See

instructions under the heading, What is what?, to ﬁnd

where these parts are located on your machine.

The life span of the machine can be reduced and the risk

of accidents can increase if machine maintenance is not

carried out correctly and if service and/or repairs are not

carried out professionally. If you need further information

please contact your nearest servicing dealer.

Chain brake and front hand guard

Your chain saw is equipped with a chain brake that is

designed to stop the chain. Should kickback occur, the

chain brake reduces the risk of accidents, but only you

can prevent them.

!

WARNING! Most chain saw accidents

happen when the chain touches the

operator. You must use approved

personal protective equipment whenever

you use the machine. Personal protective

equipment cannot eliminate the risk of

injury but it will reduce the degree of

injury if an accident does happen. Ask

your dealer for help in choosing the right

equipment.

IMPORTANT! Sparks can come from the mufﬂer, the bar

and chain or other sources. Always have ﬁre

extinguishing tools available if you should need them.

Help prevent forest ﬁres.

!

WARNING! Never use a machine with

defective safety components. Safety

equipment must be inspected and

maintained. See instructions under the

heading Checking, maintaining and

servicing chain saw safety equipment. If

your machine does not pass all the

checks, take the saw to a servicing

dealer for repair.

GENERAL SAFETY PRECAUTIONS

English – 9

Take care when using your saw and make sure the

kickback zone of the bar never touches any object.

• The chain brake (A) can either be activated manually

(by your left hand) or automatically by the inertia

release mechanism.

• The brake is applied when the front hand guard (B) is

pushed forwards.

• This movement activates a spring-loaded mechanism

that tightens the brake band (C) around the engine

drive system (D) (clutch drum).

• The front hand guard is not designed solely to activate

the chain brake. Another important feature is that it

reduces the risk of your left hand hitting the chain if

you lose grip of the front handle.

• The chain brake must be engaged when the chain

saw is started to prevent the saw chain from rotating.

• Use the chain brake as a ”parking brake” when

starting and when moving over short distances, to

reduce the risk of moving chain accidentally hitting

your leg or anyone or anything close by.

• To release the chain brake pull the front hand guard

backwards, towards the front handle.

• Kickback can be very sudden and violent. Most

kickbacks are minor and do not always activate the

chain brake. If this happens you should hold the chain

saw ﬁrmly and not let go.

• The way the chain brake is activated, either manually

or automatically by the inertia release mechanism,

depends on the force of the kickback and the position

of the chain saw in relation to the object that the

kickback zone of the bar strikes.

If you get a violent kickback while the kickback zone of

the bar is farthest away from you the chain brake is

designed to be activated by the inertia in the kickback

direction.

If the kickback is less violent or the kickback zone of

the bar is closer to you the chain brake is designed to

be activated manually by the movement of your left

hand.

• In the felling position the left hand is in a position that

makes manual activation of the chain brake

impossible. With this type of grip, that is when the left

hand is placed so that it cannot affect the movement

GENERAL SAFETY PRECAUTIONS

10 – English

of the front hand guard, the chain brake can only be

activated by the inertia action.

Will my hand always activate the chain

brake during a kickback?

No. It takes a certain force to move the hand guard

forward. If your hand only lightly touches the front guard

or slips over it, the force may not be enough to trigger the

chain brake. You should also maintain a ﬁrm grip of the

chain saw handles while working. If you do and

experience a kickback, your hand may never leave the

front handle and will not activate the chain brake, or the

chain brake will only activate after the saw has swung

around a considerable distance. In such instances, the

chain brake might not have enough time to stop the saw

chain before it touches you.

There are also certain positions in which your hand

cannot reach the front hand guard to activate the chain

brake; for example, when the saw chain is held in felling

position.

Will my inertia activated chain brake

always activate during kickback in the

event of a kickback?

No. First your brake must be in working order. Testing the

brake is simple, see instructions under the heading

Checking, maintaining and servicing chain saw safety

equipment. We recommend you do before you begin each

work session. Second the kickback must be strong

enough to activate the chain brake. If the chain brake is

too sensitive it would activate all the time which would be

a nuisance.

Will my chain brake always protect me

from injury in the event of a kickback?

No. First, the chain brake must be in working order to

provide the intended protection. Second, it must be

activated during the kickback as described above to stop

the saw chain. Third, the chain brake may be activated but

if the bar is too close to you the brake might not have

enough time to slow down and stop the chain before the

chain saw hits you.

Only you and proper working technique can eliminate

kickback and its danger.

Throttle lockout

The throttle lockout is designed to prevent accidental

operation of the throttle control. When you press the lock

(A) (i.e. when you grasp the handle) it releases the throttle

control (B). When you release the handle the throttle

control and the throttle lockout both move back to their

original positions. This arrangement means that the

throttle control is automatically locked at the idle setting.

Chain catcher

The chain catcher is designed to catch the chain if it

snaps or jumps off. This should not happen if the chain is

properly tensioned (see instructions under the heading

Assembly) and if the bar and chain are properly serviced

and maintained (see instructions under the heading

General working instructions).

Right hand guard

Apart from protecting your hand if the chain jumps or

snaps, the right hand guard stops branches and twigs

from interfering with your grip on the rear handle.

Vibration damping system

Your machine is equipped with a vibration damping

system that is designed to reduce vibration and make

operation easier.

The machine′s vibration damping system reduces the

transfer of vibration between the engine unit/cutting

equipment and the machine

′s handle unit. The body of the

chain saw, including the cutting equipment, is insulated

from the handles by vibration damping units.

GENERAL SAFETY PRECAUTIONS

English – 11

Cutting hardwoods (most broadleaf trees) creates more

vibration than cutting softwoods (most conifers). Cutting

with cutting equipment that is blunt or faulty (wrong type

or badly sharpened) will increase the vibration level.

Stop switch

Use the stop switch to switch off the engine.

Mufﬂer

The mufﬂer is designed to keep noise levels to a minimum

and to direct exhaust fumes away from the user.

In areas with a hot, dry climate there is a high risk of ﬁres.

These areas are sometimes subject to government rules

requiring among other things the mufﬂer must be

equipped with an approved type of spark arrestor screen.

Spark arrestor mufﬂer

The spark arrestor mufﬂer controls the exhaust noise and

prevents hot, glowing particles of carbon from leaving the

mufﬂer. Make sure the spark arrestor screen is in good

repair and properly seated in the mufﬂer.

Certain internal combustion engines operated on forest,

brush and/or grass-covered areas in some states, are

required to be equipped with a spark arrestor. This

requirement also applies to all US Forest Service lands.

In some of these areas, the spark arrestor system must

be certiﬁed per USDA Forest Service Regulation SAE

J335. Check with your local state authorities fo speciﬁc

regulations in your area. Failure to follow these

regulations is in violation of the law.

Cutting equipment

This section describes how to choose and maintain your

cutting equipment in order to:

• Reduce the risk of kickback.

• Reduce the risk of the saw chain breaking or jumping

off the bar.

• Obtain optimal cutting performance.

• Extend the life of cutting equipment.

• Avoid increasing vibration levels.

General rules

• Only use cutting equipment recommended by us!

See instructions under the heading Technical data.

• Keep the chain’s cutting teeth properly

sharpened! Follow our instructions and use the

recommended ﬁle gauge.

A damaged or badly

sharpened chain increases the risk of accidents.

• Maintain the correct depth gauge setting! Follow

our instructions and use the recommended depth

gauge clearance.

Too large a clearance increases

the risk of kickback.

!

WARNING! Overexposure to vibration can

lead to circulatory damage or nerve

damage in people who have impaired

circulation. Contact your doctor if you

experience symptoms of overexposure to

vibration. Such symptoms include

numbness, loss of feeling, tingling,

pricking, pain, loss of strength, changes

in skin colour or condition. These

symptoms normally appear in the ﬁngers,

hands or wrists. These symptoms may be

increased in cold temperatures.

!

WARNING! The exhaust fumes from the

engine are hot and may contain sparks

which can start a ﬁre. Never start the

machine indoors or near combustible

material!

CAUTION! During operation, the mufﬂer or catalytic

mufﬂer and surrounding cover become hot. Never

suspend the saw on a lanyard with the engine running.

Always wear proper protective clothing to protect your

lower body from sharp saw chain and hot mufﬂer.

Always keep exhaust area clear of ﬂammable debris

during transportation or when storing, otherwise serious

property damage or personal injury may result.

!

WARNING! Never use a saw without a

mufﬂer, or with a damaged mufﬂer. A

damaged mufﬂer may substantially

increase the noise level and the ﬁre

hazard. Keep ﬁre ﬁghting equipment

handy. If a spark arrestor screen is

required in your area, never use the saw

without or with a broken spark arrestor

screen.

GENERAL SAFETY PRECAUTIONS

12 – English

• Keep the chain properly tensioned! If the chain is

slack it is more likely to jump off and lead to increased

wear on the bar, chain and drive sprocket.

• Keep cutting equipment well lubricated and

properly maintained!

A poorly lubricated chain is

more likely to break and lead to increased wear on the

bar, chain and drive sprocket.

Cutting equipment designed to reduce

kickback

The only way to avoid kickback is to make sure that the

kickback zone of the bar never touches anything.

By using cutting equipment with ”built-in” kickback

reduction and keeping the chain sharp and well-

maintained you can reduce the effects of kickback.

Bar

The smaller the tip radius the lower the chance of

kickback.

Chain

A chain is made up of a number of links, which are

available in standard and low-kickback versions.

Some terms that describe the bar and chain

To maintain the safety features of the cutting equipment,

you should replace a worn or damaged bar or chain with

a bar and chain combinations recommended by RedMax.

See instructions under the heading Technical Data for a

list of replacement bar and chain combinations we

recommend.

Bar

• Length (inches/cm)

• Number of teeth on bar tip sprocket (T).

• Chain pitch (inches). The spacing between the drive

links of the chain must match the spacing of the teeth

on the bar tip sprocket and drive sprocket.

• Number of drive links. The number of drive links is

determined by the length of the bar, the chain pitch

and the number of teeth on the bar tip sprocket.

• Bar groove width (inches/mm). The groove in the bar

must match the width of the chain drive links.

• Chain oil hole and hole for chain tensioner. The bar

must be matched to the chain saw design.

Chain

• Chain pitch (inches)

• Drive link width (mm/inches)

• Number of drive links.

Maintenance of saw chain and guide bar

Chain

!

WARNING! Faulty cutting equipment or

the wrong combination of bar and saw

chain increases the risk of kickback!

Only use the bar/saw chain combinations

we recommend, and follow the ﬁling

instructions. See instructions under the

heading Technical data.

IMPORTANT! No saw chain design eliminates the

danger of kickback.

!

WARNING! Any contact with a rotating

saw chain can cause extremely serious

injuries.

!

WARNING! Keep the chain’s cutting teeth

properly sharpened! Follow our

instructions and use the recommended

ﬁle gauge. A damaged or badly sharpened

chain increases the risk of accidents.

GENERAL SAFETY PRECAUTIONS

English – 13

The cutting teeth need to be sharpened when:

• Sawdust becomes powder-like

• You need extra force to saw in

• The cut way does not go straight

• Vibration increases

• Fuel consumpion increases

Sharpening cutting teeth

Make sure the saw chain is held securely, before ﬁling!

• Place your ﬂle on the cutting teeth and push straight

forward. Keep the ﬂle position as illustrated.

Use a round ﬁle of proper size for your chain.

After every cutting tooth has been set, check the depth

gauge and ﬂle it to the proper level as illustrated.

1 Appropriate gauge checker

2 Make the shoulder round

3 Depth gauge standard

Make sure every cutting tooth has the same lenght and

egde angels as illustrated.

1 Cutting teeth lenght

2 Filing angle

3 Side plate angle

4 Top plate cutting angle

When the length of the cutting teeth has worn down to

only 5/32 inch (4 mm) the chain must be replaced.

Bar

Reverse the bar occasionally to prevent partial wear.

The bar rail should always be square. Check for wear of

the bar rail.

Tensioning the chain

The more you use a chain the longer it becomes. It is

therefore important to adjust the chain regularly to take up

the slack.

Check the chain tension every time you refuel. NOTE! A

new chain has a running-in period during which you

should check the tension more frequently.

Tension the chain as tightly as possible, but not so tight

that you cannot pull it round freely by hand.

• Loosen the bar nuts that hold the clutch cover/chain

brake. Use the combination spanner. Then tighten the

bar nuts by hand as tight as you can.

Important Always wear gloves, when working with the

chain, in order to protect your hands from injury.

!

WARNING! Departure from the

sharpening instructions considerably

increases the risk of kickback.

combination spanner. Tighten the chain until it does

not sag from the underside of the bar.

• Use the combination spanner to tighten the bar nuts

while lifting the tip of the bar at the same time. Check

that you can pull the chain round freely by hand and

that it does not sag from the underside of the bar.

The position of the chain tensioning screw on our chain

saws varies from model to model. See instructions under

the heading What is what? to ﬁnd out where it is on your

model.

Lubricating cutting equipment

Chain oil

Chain oil must demonstrate good adhesion to the chain

and also maintain its ﬂow characteristics regardless of

whether it is warm summer or cold winter weather.

We recommend the use of our own oil for maximum chain

life. If our own chain oil is not available, standard chain oil

is recommended.

Never use waste oil! Using waste oil can be dangerous

to you and damage the machine and environment.

Filling with chain oil

• All our chain saws have an automatic chain lubrication

system. On some models the oil ﬂow is also

adjustable.

• The saw chain oil tank and the fuel tank are designed

so that the fuel runs out before the saw chain oil.

However, this safety feature requires that you use the

right sort of chain oil (if the oil is too thin it will run out

before the fuel), and that you adjust the carburetor as

recommended (a lean mixture may mean that the fuel

lasts longer than the oil) and that you also use the

recommended cutting equipment (a bar that is too

long will use more chain oil).

Checking chain lubrication

• Check the chain lubrication each time you refuel. See

instructions under the heading Maintenance of saw

chain and guide bar.

Aim the tip of the bar at a light coloured surface about

20 cm (8 inches) away. After 1 minute running at 3/4

throttle you should see a distinct line of oil on the light

surface.

If the chain lubrication is not working:

• Check that the oil hole in the bar is not obstructed.

Clean if necessary.

• Check that the groove in the edge of the bar is clean.

Clean if necessary.

• Check that the oil hole in the bar is not obstructed.

Clean if necessary.

If the chain lubrication system is still not working after

carrying out the above checks and associated measures

you should contact your servicing dealer.

!

WARNING! Poor lubrication of cutting

equipment may cause the chain to snap,

which could lead to serious, even fatal

injuries.

IMPORTANT! When using vegetable based saw chain

oil, dismantle and clean the groove in the bar and saw

chain before long-term storage. Otherwise there is a risk

of the saw chain oil oxidizing, which will result in the saw

chain becoming stiff and the bar tip sprocket jamming.

GENERAL SAFETY PRECAUTIONS

English – 15

Chain drive sprocket

The clutch drum is ﬁtted with one of the following drive

sprockets:

A Spur sprocket (the chain sprocket is welded on the drum)

B Rim sprocket (replaceable)

Regularly check the degree of wear on the drive sprocket.

Replace if wear is excessive. Replace the drive sprocket

whenever you replace the chain.

Needle bearing lubrication

Both versions of sprockets have a needle bearing on the

drive shaft, which has to be greased regularly (once a

week). CAUTION! Use only high quality bearing grease or

engine oil.

See instructions under the heading Maintenance, Needle

bearing lubrication.

Checking wear on cutting equipment

Check the chain daily for:

• Visible cracks in rivets and links.

• Whether the chain is stiff.

• Whether rivets and links are badly worn.

Replace the saw chain if it exhibits any of the points

above.

We recommend you compare the existing chain with a

new chain to decide how badly the existing chain is worn.

File all the teeth to the same length. When the length of

the cutting teeth is reduced to 5/32 inch (4 mm) the chain

is worn out and should be replaced.

Bar

Check regularly:

• Whether there are burrs on the edges of the bar.

Remove these with a ﬁle if necessary.

• Whether the groove in the bar has become badly

worn. Replace the bar if necessary.

• Whether the tip of the bar is uneven or badly worn. If

a hollow forms on the underside of the bar tip this is

due to running with a slack chain.

• To prolong the life of the bar you should turn it over

daily.

!

WARNING! Most chain saw accidents

happen when the chain touches the

operator.

Wear personal protective equipment. See

instructions under the heading Personal

protective equipment.

Do not tackle any job that you feel you

are not adequately trained for. See

instructions under the headings

Personal protective equipment, How to

avoid kickback, Cutting equipment and

General working instructions.

Avoid situations where there is a risk of

kickback. See instructions under the

heading Machine

′′

s safety equipment.

Use the recommended protective

equipment and check its condition. See

instructions under the heading General

working instructions.

Check that all the chain saw safety

features are working. See instructions

under the headings General working

instructions and General safety

precautions.

ASSEMBLY

16 – English

Fitting the bar and chain

Check that the chain brake is in disengaged position by

moving the front hand guard towards the front handle.

Remove the bar nuts and remove the clutch cover (chain

brake). Take off the transportation ring (A).

Note: If clutch cover is difﬁcult to remove, replace bar

nuts, engage brake and rerelease (an audible click will be

heard if released properly).

Fit the bar over the bar bolts. Place the bar in its rearmost

position. Place the chain over the drive sprocket locate it

in the groove on the bar. Begin on the top edge of the bar.

Make sure that the edges of the cutting links are facing

forward on the top edge of the bar.

Fit the clutch cover and locate the chain adjuster pin in the

hole in the bar. Check that the drive links of the chain ﬁt

correctly over the drive sprocket and that the chain is

correctly located in the groove in the bar. Tighten the bar

nuts ﬁnger tight.

Tension the chain by turning the chain tensioning screw

clockwise using the combination wrench.

The chain is correctly tensioned when it does not sag from

the underside of the bar, but can still be turned easily by

hand. Hold up the bar tip and tighten the bar nuts ﬁrmly

with the combination wrench.

When ﬁtting a new chain, the chain tension has to be

checked frequently until the chain is run-in. Check the

chain tension regularly. A correctly tensioned chain

ensures good cutting performance and long life.

!

WARNING! Always wear gloves, when

working with the chain, in order to

protect your hands from injury.

FUEL HANDLING

English – 17

Fuel

Note! The machine is equipped with a two-stroke engine

and must always be run using a mixture of gasoline and

two-stroke oil. It is important to accurately measure the

amount of oil to be mixed to ensure that the correct

mixture is obtained. When mixing small amounts of fuel,

even small inaccuracies can drastically affect the ratio of

the mixture.

Gasoline

• Use good quality unleaded gasoline.

• CAUTION! Engines equipped with catalytic

converters must be run on unleaded fuel

mixtures.

Leaded gasoline will destroy the catalytic

converter and it will no longer serve its purpose.

Gasoline requirements

• All 2-Stroke RedMax products are powered by

Zenoah Professional-Commercial Duty, Hi-

Performance, Hi-RPM, Air Cooled 2-Stroke engines.

RedMax/Zenoah – Hi-Performance 2-stroke engines

produce higher HP outputs as compared to standard

Home Owner Duty or Light Commercial Duty

production engines offered by most manufacturers.

• Exhaust emission are controlled by the fundamental

engine parameters and components (eq. carburation,

ignition timing and port timing) without addition of any

major hardware or the introduction of an inert material

during combustion.

• The RedMax/Zenoah engines are registered and

certiﬁed with CARB (California Air Resources Board)

and EPA (Environmental Protection Agency) to

operate on CLEAN Mid-grade 89 octane or Premium,

unleaded (lead-free) gasoline and RedMax air-cooled

"MaxLife", synthetic blend Premium two-stroke engine

oil mixed at 50:1 ratio.

• Unleaded gasoline is recommended to reduce the

contamination of the air for the sake of your health and

the environment.

• This Hi-Performance Air Cooled 2-stroke Engine

requires the use of Minimum 89 Octane (R+M)/2

(Midgrade or Premium) clean gasoline. Gasoline may

contain maximum of 10% Ethanol (grain alcohol) or up

to 15% MTBE (Methyl tertiarybutylether). Gasoline

containing Methanol (Wood Alcohol) is NOT

approved.

CAUTION! Gasoline with an octane rating lower than 89

will greatly increase the engines operating temperature.

Low octane gasoline will cause detonation (knock)

resulting in piston seizures and major internal engine

components damage.

Poor quality gasolines or oils may damage sealing rings,

fuel lines or fuel tank of the engine.

CAUTION! Alternative fuels, such as E-15 (15%

ethanol), E-20 (20% ethanol), E-85 (85% ethanol) are

NOT classiﬁed as gasoline and are NOT approved for use

in RedMax 2-stroke gasoline engines. Use of alternative

fuels will cause major engine performance and durability

problems such as: improper clutch engagements,

overheating, vapor lock, power loss, lubrication

deﬁciency, deterioration of fuel lines, gaskets and internal

carburetor components, etc... Alternative fuels cause high

moisture absorption into the fuel/oil mixture leading to oil

and fuel separation.

Oil requirements

• Use only RedMax "MaxLife", Synthetic blend

Premium air-cooled two-stroke engine oil or oil

certiﬁedto ISO-L-EGD (ISO/CD1378) standard AND

one that is JASO-FD registered. RedMax air-cooled

"MaxLife", Synthetic blend Premium two stroke

engine oil and ISO-L-EGD (ISO/CD1378) AND JASO-

FD oils arefully compatible with gasoline’s containing

10% Ethanol. RedMax air-cooled "MaxLife",

Synthetic blend Premium two stroke engine oil and

ISO-L-EGD (ISO/CD1378) AND JASO-FD oils are

Universal and should be mixed at 50:1 ratio for all 2

stroke air cooled engines sold in the past regardless

of mixing ratios speciﬁed in those manuals.

• If the oil is registered with JASO, the JASO Logo with

FD and registration number will be displayed on the

container. The highest JASO rating is "FD", which

equals the ISO-L-EGD rating. Lower ratings are "FC",

"FB" and "FA".

!

WARNING! Always ensure there is

adequate ventilation when handling fuel.

!

WARNING! Gasoline is very ﬂammable.

Avoid smoking or bringing any ﬂame or

sparks near fuel. Make sure to stop the

engine and allow it to cool before

refueling the unit. Select outdoor bare

ground for fueling and move at least 10 ft

(3 m) away from the fueling point before

starting the engine.

IMPORTANT! If octane rating of the Mid Grade gasoline

in your area is lower than 89 Octane use Premium

Unleaded Gasoline. The majority of all 2-stroke engine

manufacturers in the USA and Canada recommend

using gasoline with 89 Octane or higher.

IMPORTANT! Failures caused by operating engines on

gasoline with octane rating lower than 89 are not

covered by the RedMax Two-Stroke engine warranty.

FUEL HANDLING

18 – English

• Engine problems due to inadequate lubrication

caused by failure to use ISO-L-EGD certiﬁed and

JASO FD registered oil such as "MaxLife", RedMax

Synthetic blend Premium 2-stroke oil WILL VOID THE

REDMAX TWO-STROKE ENGINE WARRANTY.

CAUTION! Do not use NMMA (National Marine

Manufacturers Association), BIA (Boating Industry

Association), and TCW (two cycle water cooled) oils

designed for mopeds or outboard water cooled marine

engines. Do not use API (American Petroleum Institute),

TC (Two Cycle) labeled oils. The API-TC test standard

has been discontinued by API in 1995 and it no longer

exists.

Gasoline/oil mixture storage recommendations

Store your gasoline or gasoline/oil mixture in a cool dry

area in a tightly sealed approved container to limit the

entry of moisture and additional air (oxygen). Moisture

and air cause the development of varnish and gum,

making the fuel stale. Stored gasoline and gasoline/oil

mixture ages and loses its octane rating and volatility. Do

not mix more gasoline/oil than you intend to use in 30

days, and 60 days when fuel stabilizer is added. RedMax

air-cooled "Max Life" synthetic blend Premium two-stroke

engine oil "contains fuel stabilizer" and will automatically

extend your gasoline/oil mixture life up to 60 days.

Mixing ratio

1:50 (2%) for all engines.

Mixing

• Always mix the gasoline and oil in a clean container

intended for fuel.

• Always start by ﬁlling half the amount of the gasoline

to be used. Then add the entire amount of oil. Mix

(shake) the fuel mixture. Add the remaining amount of

gasoline.

• Mix (shake) the fuel mixture thoroughly before ﬁlling

the machine’s fuel tank.

• Do not mix more than one month’s supply of fuel at a

time.

• If the machine is not used for some time the fuel tank

should be emptied and cleaned.

Chain oil

• We recommend the use of special RedMax bar and

chain oil with good adhesion characteristics.

• Never use waste oil. This results in damage to the oil

pump, the bar and the chain.

• It is important to use oil of the right grade (suitable

viscosity range) to suit the air temperature.

• In temperatures below 32°F (0°C) some oils become

too viscous. This can overload the oil pump and result

in damage to the oil pump components.

• Contact your service agent when choosing chain oil.

FUEL HANDLING

English – 19

Fueling

Clean the area around the fuel cap. Clean the fuel and

chain oil tanks regularly. The fuel ﬁlter must be replaced

at least once a year. Contamination in the tanks causes

malfunction. Make sure the fuel is well mixed by shaking

the container before refuelling. The capacities of the chain

oil tank and fuel tank are carefully matched. You should

therefore always ﬁll the chain oil tank and fuel tank at the

same time.

Fuel safety

• Never refuel the machine while the engine is running.

• Make sure there is plenty of ventilation when refuelling

or mixing fuel (gasoline and 2-stroke oil).

• Move the machine at least 10 ft (3 m) from the

refuelling point before starting it.

• Never start the machine:

1 If you have spilled fuel or chain oil on the machine.

Wipe off the spillage and allow remaining fuel to

evaporate.

2 If you have spilled fuel on yourself or your clothes,

change your clothes. Wash any part of your body that

has come in contact with fuel. Use soap and water.

3 If the machine is leaking fuel. Check regularly for

leaks from the fuel cap and fuel lines.

Transport and storage

• Always store the chain saw and fuel so that there is no

risk of leakages or fumes coming into contact with

sparks or naked ﬂames from electrical equipment,

electric motors, relays/switches, boilers and the like.

• Always store fuel in an approved container designed

for that purpose.

• For longer periods of storage or for transport of the

chain saw, the fuel and chain oil tanks should be

emptied. Ask where you can dispose of waste fuel and

chain oil at your local gas station.

• Ensure the machine is cleaned and that a complete

service is carried out before long-term storage.

• The bar guard must always be ﬁtted to the cutting

attachment when the machine is being transported or

in storage, in order to prevent accident contact with

the sharp chain. Even a non-moving chain can cause

serious cuts to yourself or persons you bump into with

an exposed chain.

Long-term storage

Empty the fuel/oil tanks in a well ventilated area. Store the

fuel in approved cans in a safe place. Fit the bar guard.

Clean the machine. See instructions under the heading

Maintenance schedule.

!

WARNING! Taking the following

precautions, will lessen the risk of ﬁre:

Do not smoke and do not place any hot

objects in the vicinity of fuel.

Always stop the engine and let it cool for

a few minutes before refuelling.

When refuelling, open the fuel cap slowly

so that any excess pressure is released

gently.

Tighten the fuel cap carefully after

refuelling.

Always move the machine away from the

refuelling area before starting.

!

WARNING! Fuel and fuel vapor are highly

ﬂammable. Take care when handling fuel

and chain oil. Be aware of the risks of

ﬁre, explosion and those associated with

inhalation.

!

WARNING! Never use a machine with

visible damage to the spark plug guard

and ignition cable. A risk of sparking

arises, which can cause a ﬁre.

STARTING AND STOPPING

20 – English

Starting and stopping

Cold engine

Starting: The chain brake should be activated when

starting the chain saw. Activate the chain brake by

pushing the front hand guard forwards.

Ignition; choke: Set the choke control in the choke

position. This should automatically set the stop switch to

the start position.

Start throttle: The correct choke/start throttle setting is

obtained by moving the control to the choke position.

Air purge: If the machine is ﬁtted with an air purge (A):

Press the air purge repeatedly until fuel begins to ﬁll the

bulb. The bulb need not be completely ﬁlled.

Decompression valve: If the machine is ﬁtted with a

decompression valve (B): Press the valve to reduce the

pressure in the cylinder and make starting easier. You

should always use the decompression valve when

starting the machine. Once the machine has started the

valve will automatically return to its original setting.

Warm engine

Use the same procedure as for starting a cold engine but

without setting the choke control in the choke position.

The correct choke/start throttle setting is obtained by

moving the choke control to the choke position and then

pushing it in again.

Starting

Grip the front handle with your left hand. Hold the chain

saw on the ground by placing your right foot through the

rear handle. Pull the starter handle with your right hand

and pull out the starter cord slowly until you feel a

resistance (as the starter pawls engage) then pull ﬁrmly

and rapidly.

Never wrap the starter cord around your

hand

CAUTION! Do not pull the starter cord all the way out and

do not let go of the starter handle when the cord is fully

extended. This can damage the machine.

Push in the choke control as soon as the engine ﬁres and

make repeated starting attempts. Immediately press and

release the throttle when the engine starts. That will

disengage the throttle latch.

!

WARNING! Note the following before

starting:

The chain brake must be engaged when

the chain saw is started to reduce the

chance of contact with the moving chain

during starting.

Never start a chain saw unless the bar,

chain and all covers are ﬁtted correctly.

Otherwise the clutch can come loose and

cause personal injuries.

Place the machine on ﬁrm ground. Make

sure you have a secure footing and that

the chain cannot touch anything.

Keep people and animals well away from

the working area.
