Check for Loose Fasteners and Parts, Lubrication

NOTE: It is normal for a small amount of oil to appear under the saw after engine stops. Do not confuse this with a leaking oil tank.

S ON/STOP Switch -- Ensure ON/STOP switch functions properly by moving the switch to the STOP position. Make sure en- gine stops; then restart engine and continue.

S Fuel Tank -- Do not use saw if fuel tank shows signs of damage or leaks.

SOil Tank -- Do not use saw if oil tank shows signs of damage or leaks.

CHECK CHAIN SHARPNESS

A sharp chain makes wood chips. A dull chain makes a sawdust powder and cuts slowly. See CHAIN SHARPENING.

CHECK GUIDE BAR

Conditions which require guide bar mainte- nance:

S Saw cuts to one side or at an angle. S Saw has to be forced through the cut. S Inadequate supply of oil to bar/chain.

Check the condition of guide bar each time chain is sharpened. A worn guide bar will damage the 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:

S Move ON/STOP switch to STOP.

S Loosen and remove bar nuts and clutch cover. Remove bar and chain from saw.

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

Remove Sawdust From

Guide Bar Groove

Oil Holes

S Burring 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.

File Rail Edges

and Sides

Square

Worn Groove

Correct Groove

Replace guide bar when the groove is worn, the guide bar is bent or cracked, or when ex- cess heating 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.

CHECK FUEL MIXTURE LEVEL

SSee GUIDE BAR AND CHAIN OIL under the OPERATION section.

INSPECT AND CLEAN UNIT AND DECALS

S After each use, inspect complete unit for loose or damaged parts. Clean the unit and decals using a damp cloth with a mild deter- gent.

SWipe off unit with a clean dry cloth.

CHECK CHAIN BRAKE

See CHAIN BRAKE in the OPERATION section.

CLEAN 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 the life and perfor- mance of the engine and increases fuel con- sumption and harmful emissions. Always clean your air filter after 10 tanks of fuel or 5 hours of operation, whichever comes first. Clean more frequently in dusty conditions. A used air filter can never be completely cleaned. It is advisable to replace your air fil- ter with a new one after every 50 hours of op- eration, or annually, whichever comes first.

1.Loosen 3 screws on cylinder cover.

2.Remove cylinder cover.

3.Remove air filter cover and air filter.

4.Clean the air filter using hot soapy water. Rinse with clean cool water. Air dry com- pletely before reinstalling.

5.Reinstall air filter and air filter cover.

6.Reinstall cylinder cover and 3 screws. Tighten securely.
