when the weight of the chain does not
cause it to sag below the guide bar
(with the chain saw sitting in an upright
position), but the chain stil! moves freeiy
around the guide bar.
A WARNING:
If the saw is operated
with a boss chain, the chain couid jump
off the guide bar and result in serious
injury to the operator and/or damage the
chain making it unusable. If the chain
jumps off the guide bar, inspect each
drive link for damage. Damaged chain
must be repaired or replaced,
CHECK CHAIN SHARPNESS
A sharp chain makes wood chips. A duil
chain makes a sawdust powder and
cuts slowly. See CHAIN SHARPENING.
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,
