S Use the screwdriver end of the bar tool to
move chain around guide bar.
S If chain does not rotate, it is too tight.
Slightly loosen chain brake nuts and loos-
en chain by turning the adjusting screw.
Retighten chain brake nuts.
S If chain is too loose, it will sag below the
guide bar. DO NOT operate the saw if the
chain is loose.
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 an upright position), but the chain still moves
freely around the guide bar.
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 op-
erator and/or damage the chain making it un-
usable. If the chain jumps off the guide bar, in-
spect each drive link for damage. Damaged
chain must be repaired or replaced.
