CHAIN TENSION
(Including units with chain atready h_stalled)
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.

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 theyare fingertight
against the clutch cover.
2. Turn adjusting screw clockwise until chain
