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 nuts are finger tight only.
Attempting to tension the chain when the bar
nuts are tight can cause damage.
Checking the tension:
Use the screwdriver end of the chain adjust-
ment tool (bar tool) 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 you
use and refuel your saw.
1. Loosen bar nuts until they are finger tight
against the clutch cover.
2. Turn adjusting screw clockwise until chain
solidly contacts bottom of guide bar rail.

nuts securely with the bar tool.
6. Use the screwdriver end of the bar tool to
move chain around guide bar.
7. If chain does not rotate, it is too tight.
Slightly loosen bar nuts and loosen chain
by turning the adjusting screw
counterclockwise. Retighten bar nuts.
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:
with a loose chain, the chain could jump off
the guide bar and result in serious injury.
WARNING:
and after use. Do not touch the muffler or al-
low combustible material such as dry grass
or fuel to do so.
