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

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.

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.
