CHECK CHAIN SHARPNESS
A sharp chain makes wood chips, A
dull chain makes a sawdust powder
and cuts slowly. See CHAIN SHARP-
ENING in the SERVICE AND ADJUST-
MENTS 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 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 STOE
• Loosen and remove chain brake
nuts and chain brake. Remove bar
and chain from saw.
• Clean the oil holes and bar groove
after each 5 hours of operation.

process of rail wear. Remove these
burrs with a flat file,
