ASSEMBLY
CHAIN TENSION (including
units with chain already
installed)
WARNING:
Wear protective gloves
when handling chain. The chain is sharp and
can cut you even when it is not moving.
NOTE:
When adjusting chain tension,
make sure the bar knob is finger tight only.
Attempting to tension the chain when the bar
knob is tight can cause damage.
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.

Adjusting the tension:
Chain tension is very important. Chains
stretch during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time be-
fore you start the chain saw.

tion.
WARNING:
Failure to return lever on
bar knob to original position could result in
serious personal injury or damage to your
chain saw.
6. Use a screwdriver to move chain around
guide bar.
7. If chain does not rotate, it is too tight. Use
the lever to loosen bar knob 1 turn (coun-
terclockwise); then, loosen chain by
turning the outer tensioning ring (counter-
clockwise). Retighten bar knob.
8. 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.
WARNING:
If the saw is operated
with a loose chain, the chain could jump off
the guide bar and result in serious injury.
WARNING:
Muffler is very hot during
and after use. Do not touch the muffler or al-
low combustible material such as dry grass
or fuel to do so.
