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 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.
An adjusting screw (located on the guide
bar) is used to adjust the tension of the chain
(see illustration).
1. Turn adjusting screw clockwise until chain
solidly contacts bottom of guide bar rail.

4. While lifting tip of guide bar, tighten bar

guide bar. DO NOT operate the saw if
the chain is loose.
