Cleaning the air filter:

A dirty air filter decreases engine perform-

ance and increases fuel consumption and

harmful emissions. Always clean after 10

tanks of fuel or 5 hours of operation, which-

ever comes first. Clean more frequently in

dusty conditions. A used aire filter can never

be completely cleaned. It is advisable to re-

place your air filter with a new one after every

50 hours of operation, or annually, whichever

comes first.

1. Loosen 3 screws on cylinder cover.

2. Remove cylinder cover.

3. Remove air filter.

4. Clean the air filter using hot soapy water.

Rinse with clean cool water. Air dry com-

pletely before reinstalling.

5. Lightly oil air filter before installing to im-

prove the efficiency of air filter. Use

2--cycle engine oil or motor oil (SAE 30).

Squeeze excess oil from filter.

6. Reinstall air filter.

7. Reinstall cylinder cover and 3 screws.

TIghten securely.

CARBURETOR ADJUSTMENT

WARNING:

The chain will be mov-

ing 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.

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.

Turn idle speed screw (T) counterclock-

wise to decrease engine speed.
