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 fr

ont hand guard

Y

our chain saw is equipped with a chain brake that is

designed to stop the chain if you get a kickback. The chain

brake reduces the risk of accidents, but only you can prevent

them.

Take care when using your saw and make sure the kickback

zone of the bar never touches any object.

!

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.

8 – Canadian

GENERAL SAFETY PRECAUTIONS

• 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 the chain hitting your left hand 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.

Canadian – 9

GENERAL SAFETY PRECAUTIONS

• 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 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 inetria 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 to 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 lock

The throttle lock 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 lock

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. Replace it if necessary with an aluminium chain

catcher (is available as spare part). 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.

10 – Canadian

GENERAL SAFETY PRECAUTIONS

The body of the chain saw, including the cutting equipment, is

insulated from the handles by vibration damping units.

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 mesh.

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! The mufﬂer gets very hot during and after use.

This also applies during idling. Be aware of the ﬁre hazard,

especially when working near ﬂammable substances and/

or vapours.

!

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.

Canadian – 11

GENERAL SAFETY PRECAUTIONS

• 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 Jonsered. 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.

!

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.

GENERAL SAFETY PRECAUTIONS

Sharpening your chain and adjusting

depth gauge setting

General information on sharpening cutting teeth

• Never use a blunt chain. When the chain is blunt you have

to exert more pressure to force the bar through the wood

and the chips will be very small. If the chain is very blunt it

will produce wood powder and no chips or shavings.

• A sharp chain eats its way through the wood and produces

long, thick chips or shavings.

• The cutting part of the chain is called the cutter and

consists of a cutting tooth (A) and the depth gauge (B).

The cutters cutting depth is determined by the difference

in height between the two (depth gauge setting).

When you sharpen a cutting tooth there are four important

factors to remember.

1 Filing angle

2 Cutting angle

3 File position

4 Round ﬁle diameter

It is very difﬁcult to sharpen a chain correctly without the right

equipment. We recommend that you use our ﬁle gauge. This

will help you obtain the maximum kickback reduction and

cutting performance from your chain.

See instructions under the heading Technical data for

information about sharpening your chain.

Sharpening cutting teeth

To sharpen cutting teeth you will need a round ﬁle and a ﬁle

gauge. See instructions under the heading Technical data for

information on the size of ﬁle and gauge that are

recommended for the chain ﬁtted to your chain saw.

• Check that the chain is correctly tensioned. A slack chain

will move sideways, making it more difﬁcult to sharpen

correctly.

• Always ﬁle cutting teeth from the inside face. Reduce the

pressure on the return stroke. File all the teeth on one side

ﬁrst, then turn the chain saw and ﬁle the teeth on the other

side.

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

the cutting teeth is reduced to 4 mm (0.16") the chain is

worn out and should be replaced.

!

WARNING! Departure from the sharpening

instructions considerably increases the risk

of kickback.

Canadian – 13

GENERAL SAFETY PRECAUTIONS

General advice on adjusting depth gauge setting

• When you sharpen the cutting tooth (A) the depth gauge

setting (C) will decrease. To maintain optimal cutting

performance the depth gauge (B) has to be ﬁled down to

achieve the recommended depth gauge setting.

See instructions under the heading Technical data to ﬁnd

the correct depth gauge setting for your particular chain.

Adjustment of depth gauge setting

• The cutting teeth should be newly sharpened before

adjusting the depth gauge setting. We recommend that

you adjust the depth gauge setting every third time you

sharpen the cutting teeth. NOTE! This recommendation

assumes that the length of the cutting teeth is not reduced

excessively.

• You will need a ﬂat ﬁle and a depth gauge tool. We

recommend that you use our depth gauge tool to acheive

the correct depth gauge setting and bevel for the depth

gauge.

• Place the depth gauge tool over the chain. Detailed

information regarding the use of the depth gauge tool, will

be found on the package for the depth gauge tool. Use the

ﬂat ﬁle to ﬁle off the tip of the depth gauge that protrudes

through the depth gauge tool. The depth gauge setting is

correct when you no longer feel resistance as you draw

the ﬁle along the depth gauge tool.

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.

• Raise the tip of the bar and stretch the chain by tightening

the chain tensioning screw using the 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.

!

WARNING! The risk of kickback is increased

if the depth gauge setting is too large!

!

WARNING! A slack chain may jump off and

cause serious or even fatal injury.

GENERAL SAFETY PRECAUTIONS

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.

As a chain saw manufacturer we have developed an optimal

chain oil which has a vegetable oil base. We recommend the

use of our own oil for both maximum chain life and to minimise

environmental damage. 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 weak 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).

The above conditions also apply to chain saw models with

an adjustable oil pump.

Checking chain lubrication

• Check the chain lubrication each time you refuel. See

instructions under the heading Lubricating the bar tip

sprocket.

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 channel 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 bar tip sprocket turns freely and that the

lubricating hole in the tip sprocket is not blocked. Clean

and lubricate 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.

Canadian – 15

GENERAL SAFETY PRECAUTIONS

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.

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.

When the length of the cutting teeth has worn down to only 4

mm (0,16 inch) the chain must 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.

!

ASSEMBLY

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).

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 spanner. The chain should

be tensioned until it does not sag from the underside of the

bar. See instructions under the heading Tensioning the chain.

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 with the

combination spanner.

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.

FUEL HANDLING

Fuel

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

must always been run using a mixture of gasoline and two-

stroke engine 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

• This engine is certiﬁed to operate on unleaded

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. The green fuel cap on

saws ﬁtted with catalytic converters means that only

unleaded gasoline can be used.

• The lowest recommended octane grade is 87

((RON+MON)/2). If you run the engine on a lower octane

grade than 87 so-called knocking can occur. This gives

rise to a high engine temperature and increased bearing

load, which can result in serious engine damage.

• When working with continuous high revs (e.g. limbing) a

higher octane is recommended.

Environment fuel

JONSERED recommends the use of alkylate fuel or

environment fuel for four-stroke engines blended with two-

stroke oil as set out below. Note that carburetor adjustment

may be necessary when changing the type of fuel (see the

instructions under the heading Carburetor).

Running-in

Avoid running at a too high speed for extended periods during

the ﬁrst 10 hours.

Two-stroke oil

• For best results and performance use JONSERED two-

stroke engine oil, which is specially formulated for our air-

cooled two stroke-engines.

• Never use two-stroke oil intended for water-cooled

engines, sometimes referred to as outboard oil (rated

TCW).

• Never use oil intended for four-stroke engines.

• A poor oil quality and/or too high oil/fuel ratio may

jeopardise function and decrease the life time of catalytic

converters.

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 oil (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 0°C (32°F) 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.

!

WARNING! Always ensure there is adequate

ventilation when handling fuel.

FUEL HANDLING

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 (petrol and 2-stroke oil).

• Move the machine at least 3 m from the refuelling point

before starting it.

• Never start the machine:

1 If you have spilt fuel or chain oil on the machine. Wipe off

the spillage and allow remaining fuel to evaporate.

2 If you have spilt 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 petrol 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

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.

If the machine is ﬁtted with a decompression valve (A): 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 twist

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 ﬁre and make

repeated starting attempts. Immediately press and release

the throttle when the engine starts. That will disengage the

throttle latch.

As the chain brake is still activated the engine must return to

idling speed as soon as possible by disengaging the throttel

latch in order to avoid unnecessery wear on the clutch

assembly.

!

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.

Note! Pull the front hand guard towards the front handle. The

chain brake is now disengaged. Your saw is ready for use.

• Never start a chain saw unless the bar, chain and all

covers are ﬁtted correctly. See instructions under the

heading Assembly. Without a bar and chain attached to

the chain saw the clutch can come loose and cause

serious injury.

• The chain brake should be activated when starting. Se

instructions under the heading Start and stop. Do not drop

start. This method is very dangerous because you may

lose control of the saw.

• Never start the machine indoors. Exhaust fumes can be

dangerous if inhaled.

• Observe your surroundings and make sure that there is no

risk of people or animals coming into contact with the

cutting equipment.

• Always hold the saw with both hands. The right hand

should be on the rear handle, and the left hand on the front

handle. All people, whether right or left handed, should

use this grip. Use a ﬁrm grip with thumbs and ﬁngers

encircling the chain saw handles.

Stopping

The engine is stopped by pushing the stop switch to the stop

position.

!

WARNING! Long term inhalation of the

engine’s exhaust fumes, chain oil mist and

dust from sawdust can represent a health

risk.
