Cleaning the air filter:

A dirty air filter decreases engine perform- ance and increases fuel consumption and harmful emissions. Always clean after 15 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 ADJUSTMENTS

Your carburetor is equipped with limiter caps. Carburetor adjustment is a complicated task. We recommend that you take your unit to an authorized service dealer. Damage will occur if you turn the needles beyond the limiter stops.

BAR MAINTENANCE

If your saw cuts to one side, has to be forced through the cut, or been run with an improper amount of bar lubrication it may be necessary to service your bar. A worn bar will damage your chain and make cutting difficult.

After each use, ensure ON/STOP switch is in the STOP position, then clean all sawdust from the guide bar and sprocket hole.

To maintain guide bar:

SMove ON/STOP switch to the STOP posi- tion.

SLoosen and remove chain brake nuts and chain brake. Remove bar and chain from

saw.

SClean the oil holes and bar groove after each 5 hours of operation.

Oil Holes

SBurring of guide bar rails is a normal process of rail wear. Remove these burrs with a flat

file.

SWhen rail top is uneven, use a flat file to re- store square edges and sides.

ssheating or burring of the rails occurs. If re- placement 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.

CHAIN SHARPENING

Chain sharpening is a complicated task that requires special tools. We recommended you refer chain sharpening to a professional chain sharpener.
