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:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the cut.
• 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:
• Move ON/STOP switch to STOR
• Loosen and remove bar nuts and clutch
cover. Remove bar and chain from saw.
• Clean the oil holes and bar groove after
each 5 hours of operation.
