Replace guide bar when the groove is worn,

the guide bar is bent or cracked, or when

excess heating or burring of the rails occurs.

If replacement is necessary, use only the guide

bar specified for your saw in the repair parts list

or on the decal located on the chain saw.

AIR FILTER

CAUTION:

Do not clean filter in gasoline or

other flammable solvent to avoid creating a

fire hazard or producing harmful evaporative

emissions.

Cleaning the air filter:

A dirty air filter decreases engine perform-

ance and increases fuel consumption and

harmful emissions. Always clean after every

5 hours of operation.
1. Clean the cover and the area around it to

keep dirt and sawdust from falling into

the carburetor chamber when the cover

is removed.

2. Remove the parts as illustrated below.

3. Wash the filter in soap and water. Rinse

in clean cool water. Air dry completely

before reinstalling.

4. Add a few drops of oil to the filter;

squeeze filter to distribute oil.

5. Reinstall parts.

SPARK PLUG

The spark plug should be replaced each

year to ensure the engine starts easier and

runs better. Ignition timing is fixed and non-

adjustable.
1. Loosen 3 screws on cylinder cover.

2. Remove the cylinder cover.

3. Pull off the spark plug boot.

4. Remove spark plug from cylinder and

discard.

5. Replace with Champion RCJ--7Y spark

plug and tighten securely with a 19 mm

socket wrench. Spark plug gap should

be 0,5 mm.

6. Reinstall the spark plug boot.

7. Reinstall the cylinder cover and 3

screws. Tighten securely.

WARNING

:

Disconnect the spark

plug before performing maintenance, ser-

vice or adjustments, except for carburetor

adjustments.

CHAIN SHARPENING

Chain sharpening is a complicated task that

requires special tools. We recommend that

you refer chain sharpening to a professional

chain sharpener.

CARBURETOR ADJUSTMENT

The chain will be moving during most of this

procedure. Wear your protective equipment

and observe all safety precautions. The chain

must not move at idle speed.
The carburetor has been carefully set at the

factory. Adjustments may be necessary if

you notice any of the following conditions:

S

Chain moves at idle. See IDLE SPEED--T

adjusting procedure.

S

Saw will not idle. See IDLE SPEED--T ad-

justing procedure.

Idle Speed

--

T

Allow engine to idle. If the chain moves, idle

is too fast. If the engine stalls, idle is too slow.

Adjust speed until engine runs without chain

movement (idle too fast) or stalling (idle too

slow). The idle speed screw is located in the

area above the primer bulb and is labeled T.

S

Turn idle speed screw (T) clockwise to in-

crease engine speed.

S

Turn idle speed screw (T) counterclock-

wise to decrease engine speed.

STORAGE

WARNING

:

Stop engine and allow to

cool, and secure the unit before storing or

transporting in a vehicle. Store unit and fuel

in an area where fuel vapors cannot reach

sparks or open flames from water heaters,

electric motors or switches, furnaces, etc.

Store unit with all guards in place. Position so

that any sharp object cannot accidentally

cause injury to passersby. Store the unit out

of reach of children.

S

Before storing, drain all fuel from the unit.

Start engine and allow to run until it stops.

S

Clean the unit before storing. Pay particu-

lar attention to the air intake area, keeping

it free of debris. Use a mild detergent and

sponge to clean the plastic surfaces.

S

Do not store the unit or fuel in a closed area

where fuel vapors can reach sparks or an

open flame from hot water heaters, electric

motors or switches, furnaces, etc.

S

Store in a dry area out of the reach of chil-

dren.

CAUTION

:

It is important to prevent

gum deposits from forming in essential fuel

system parts such as the carburetor, fuel fil-

ter, fuel hose, or fuel tank during storage. Al-

cohol blended fuels (called gasohol or using

ethanol or methanol) can attract moisture

which leads to fuel mixture separation and

formation of acids during storage. Acidic gas

can damage the engine.
