4. For safe operation

1. Never operate a chain saw when you are

fatigued, ill, or upset, or under the

influence of medication that may make

you drowsy, or if you are under the

influence of alcohol or drugs.

2. Use safety footwear, snug fitting clothing

and eye, hearing and head protection

devices.

3. Always use caution when handling fuel.

Wipe up all spills and then move the

chain saw at least ten(10) feet(three(3)

m) from the fueling point before starting

the engine.

3a)Eliminate all sources of sparks or

flame (ie. smoking, open flames, or

work that can cause sparks) in the

areas where fuel is mixed, poured, or

stored.

3b) Do not smoke while handling fuel or

while operating the chain saw.

4. Do not allow other persons to be near

the chain saw when starting the engine

or cutting a wood. Keep bystanders and

animals out of the work area. Children,

pets, and bystanders should be a

minimum of thirty(30) feet away when

you start or operate the chain saw.

5. Never start cutting until you have a clear

work area, secure footing, and planned

retreat path from the falling tree.

6. Always hold the chain saw firmly with

both hands when the engine is running.

Use a firm grip with thumb and fingers

encircling the chain saw handles.

7. Keep all parts of your body away from

the saw chain when the engine is

running.

8. Before you start the engine, make sure

the saw chain is not contacting anything.

9. Always carry the chain saw with the

engine stopped, the guide bar and saw

chain to the rear, and the muffler away

from your body.

10. Always inspect the chain saw before

each use for worn, Ioose, or changed

parts. Never operate a chain saw that is

damaged, improperly adjusted, or is not

completely and securely assembled. Be

sure that the saw chain stops moving

when the throttle control trigger is

released.

11. All chain saw service, other than the

items listed in the Operator’s Manual,

should be performed by competent chain

saw service personnel. (e.g., 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 which could subsequently cause

the flywheel to disintegrate).

12. Always shut off the engine before setting

it down.

13. 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.

14.When cutting a limb that is under

tension, be alert for spring back so that

you will not be struck when the tension in

the wood fibers is released.

15. Keep the handles dry, clean and free of

oil or fuel mixture.

❲

❳

4. For safe operation

16.Operate the chain saw only in well

ventilated areas. Never start or run the

engine inside a closed room or building.

Exhaust fumes contain dangerous

carbon monoxide.

17. Do not operate a chain saw in a tree

unless specially trained to do so.

18. Guard against kickback. Kickback is the

upward motion of the guide bar which

occurs when the saw chain at the nose

of the guide bar contacts an object.

Kickback can lead to dangerous loss of

control of the chain saw.

19. When transporting your chain saw, make

sure the appropriate guide bar scabbard

is in place.

20. This chain saw is equipped with a spark

arrester built-in muffler. Periodically

check the arrester to keep it in good

order.

KICKBACK SAFETY PRECAUTIONS FOR

CHAIN SAW USERS

● 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 on the safety devices built into your saw. As a chain saw user you

should take several steps to keep cutting jobs free from accident or injury.

(1) With a basic understanding of kickback you can reduce or eliminate the element of

surprise. Sudden surprise contributes to accidents.

(2) Keep a good 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.

(3) Make certain that the area in which you’re cutting is free from obstructions. Do not let

the nose of the guide bar contact a log, branch, or any other obstruction which could

be hit while you are operating the saw.

(4) Cut at high engine speeds.

(5) Do not overreach or cut above shoulder height.

(6) Follow manufacturers sharpening and maintenance instructions for saw chain.

(7) Only use replacement bars and chains specified by the manufacturer or the

equivalent.

6. Fuel and Chain oil

■ FUEL

The RedMax engines are lubricated by oil specially

formulated for air-cooled 2-cycle gasoline engine

use. If RedMax oil is not available, use an anti-

oxidant added quality oil expressly labeled for air-

cooled 2-cycle engine use.

RECOMMENDED MIXING RATIO

GASOLINE 32 : OIL 1

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.

These engines are certified to operate on

unleaded gasoline.

The fuel is highly flammable. Do not smoke or

bring any flame or sparks near fuel.

■ HOW TO MIX FUEL

1. Measure out the quantities of gasoline and oil to

be mixed.

2. Put some of the gasoline into a clean, approved

fuel container.

3. Pour in all of the oil and agitate well.

4. Pour in the rest of gasoline and agitate again for

at least one minute.

5. Put a clear indication on the outside of the

container to avoid mixing up with gasoline or

other containers.

FOR YOUR ENGINE LIFE, AVOID;

1. FUEL WITH NO OIL(RAW GASOLINE) – It will

cause severe damage to the engine inner parts

very quickly.

2. GASOHOL – It can cause deterioration of rubber

and/or plastic parts and disruption of engine

lubrication.

3. OIL FOR 4-CYCLE ENGINE USE or WATER

COOLED 2-CYCLE ENGINE USE – It can

cause spark plug fouling, exhaust port blocking,

or piston ring sticking.

■ CHAIN BRAKE

This machine is equipped with an automatic brake

to stop saw chain rotation upon occurrence of

kickback while in saw cutting operation. The brake

is automatically operated by inertial force which

acts on the weight fitted inside the front guard.

This brake can also be operated manually with the

front guard turned down to the guide bar.

To release brake, pull up the front guard toward the

front handle till "click" sound is heard. (F15)

Be sure to confirm brake operation on the daily

inspection.

How to confirm:

1) Turn off the engine.

2) Holding the chain saw horizontally, release your

hand from the front handle, hit the tip of the

guide bar to a stump or a piece of wood, and

confirm brake operation. Operating level varies

by bar size. (F16)

In case the brake is not effective, ask our dealer

inspection and repairing.

The engine, If being kept rotated at high speed with

the brake engaged, heats the clutch, causing a

trouble.

When the brake is operated while in operation,

immediately release your fingers from the throttle

lever and stop the engine.

Carburetor anti-freeze mechanism

Operating the chain saws in temperatures of 0–5°C

at times of high humidity may result in ice forming

within the carburetor, and this in turn may cause

the output power of the engine to be reduced or for

the engine to fail to operate smoothly.

This product has accordingly been designed with a

ventilation hatch on the right side of the surface of

the cylinder cover to allow warm air to be supplied

to the engine and to thereby prevent icing from

occurring.

Under normal circumstances the product should be

used in normal operating mode, i.e., in the mode to

which it is set at the time of shipment. However

when the possibility exists that icing may occur, the

unit should be set to operate in anti-freeze mode

before use.(F18)

(1) Normal operating mode

(2) Anti-freeze mode

(3) Cylinder cover

(4) ‘Sun shine’ mark

(5) ‘Snow’ mark

Continuing to use the product in anti-freeze

mode even when temperatures have risen and

returned to normal may result in the engine

failing to start properly or in the engine failing

to operate at its normal speed, and for this

reason you should always be sure to return the

unit to normal operating mode if there is no

danger of icing occurring.

F19

• Before proceeding to your job, read "For

Safe Operation" section It is recommended

to first practice sawing easy logs. This also

helps you get accustomed to your unit.

• Always follow the safety regulations. The

chain saw must only be used for cutting

wood. It is forbidden to cut other types of

material. Vibrations and kickback vary with

different materials and the requirements of

the safety regulations would not be

respected. Do not use the chain saw as a

lever for lifting, moving or splitting objects.

Do not lock it over fixed stands. It is

forbidden to hitch tools or applications to the

P.t.o. that are not specified by the

manufacturer.

• It is not necessary to force the saw into the

cut. Apply only light pressure while running

the engine at full throttle.

• When the saw chain is caught in the cut, do

not attempt to pull it out by force, but use a

wedge or a lever to open the way.

■ GUARD AGAINST KICKBACK (F21)

• This saw is equipped with a chain brake that will

stop the chain in the event of kickback if

operating properly. You must check the chain

brake operation before each usage by running

the saw at full the throttle for I -2 seconds and

pushing the front hand guard forward. The chain

should stop immediately with the engine at full

speed. If the chain is slow to stop or does not

stop, replace the brake band and clutch drum

before use.

• It is extremely important that the chain brake be

checked for proper operation before each use

and that the chain be sharp in order to maintain

the kickback safety level of this saw. Removal of

the safety devices, inadequate maintenance, or

incorrect replacement of the bar or chain may

increase the risk ot serious personal injury due

to kickback.
