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 loosening
the bar clamp nuts and turning the adjusting
screw 1/4 of a tum while IAing up on the bar.
•
If chain is too tight, turn adjusting
screw 1/4 turn counterclockwise.
