CHAIN TENSION (Including units
with chain already installed)
NOTE: When adjusting chah_ tension,
make sure the chah_ 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 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.
Chain Adjustment
Chain Brake Nuts Tool (Bar Tool)
Adjusting the tension:
Chah_ tension is very h-nportant. 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.
• If chain is too tight, turn adjusting screw 1/4
turn counterclockwise.
• If chain is too loose, turn adjusting screw
1/4 turn clockwise.
