tight only. Attempting to tension the chain
when the chain brake nuts are tight can
cause damage.

tight. If too loose, the chain will sag belowthe
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).
1. Turn adjusting screw clockwise until
chain solidly contacts bottom of guide
