CHAIN TENSION (Including units
with chain already installed)
When adjusting chain tension, make sure
the chain brake nuts are finger tight only. At-
tempting 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.

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.
An adjusting screw (located on the guide bar)
is used to adjust the tension of the chain (see
illustration).
