TENSIONING THE CHAIN
(Including units with chain already installed)
a WARNING: If the saw is operated with
a loose chain, the chain could 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.
Chain tension is very important. Chains stretch during

you use your saw. Always check chain tension each
time before you start the chain saw.

checked frequently until the chain is run-in.
A correctly tensioned chain ensures good cutting
performance and long life.
CHECKING THE TENSION
Use a screwdriver to move chain around guide bar. If
the chain does not rotate, it is too tight. If the chain is
too loose, it will sag below the bar.
NOTE: The chain is tensioned correctly when
the weight of the chain does not cause it to sag
below the guide bar (with the chain saw sitting in

around the guide bar.
