with a loose chain, the chain could

CHECK CHA N SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN
SHARPENING in the SERVICE AND
ADJUSTMENTS section.
CHECK GUIDE BAR
Conditions which require guide bar
maintenance:
• Saw cuts to one side or at an angle.
• Saw has to be forced through the
cut.
• Inadequate supply of oil to the bar
and chain.
Check the condition of the guide bar
each time the chain is sharpened. A
worn guide bar will damage the chain
and make cutting difficult.
After each use, with unit disconnected
from power source, clean all sawdust
from the guide bar and sprocket hole.
To maintain guide bar:
• Disconnect the chain saw from the
power source.
