CHAIN TENSION (Including units with

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 combination
assembly tool to move the chain around the
bar. If the chain does not rotate, it is too tight.
If too loose, the chain will sag below the bar.

Adjusting the tension:
Chain tension is very important. Chain
stretches 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.
You can adjust the chain tension by loosen-
ing the chain brake nuts and turning the ad-
justing screw 1/4 of a turn while lifting up on
the bar.
S If chain is too tight, turn adjusting
screw 1/4 turn counterclockwise.
S If chain is too loose, turn adjusting
screw 1/4 turn clockwise.
