CHECK
CHAIN SHARPNESS
A sharp chain makes wood chips. A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING.
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 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 STOP.
• 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.
