CHAIN TENSION (Including units with
chain already installed)
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.
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.
S An adjusting screw (located on the guide
bar) is used to adjust the tension of the
chain (see illustration).
Turn adjusting
screw clockwise until chain solidly con-
tacts bottom of guide bar rail.
