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 loosen-
ing the chain brake nuts and turning the ad-
justing screw 1/4of a turn while lifting up on
the bar.
