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 chain brake nuts are finger
tight only. Attempting to tension the chain
when the chain brake 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.
3. Using bar tool, roll chain around guide bar
to ensure all links are in bar groove.
4. Lift up tip of guide bar to check for sag.
Release tip of guide bar, then turn ad-
justing screw
until sag does not exist.
5. While lifting tip of guide bar, tighten bar
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
turn 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.

with a loose chain, the chain could jump off
the guide bar and result in serious injury.
