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 1/4 of a turn while lifting up on the bar.
SIf chain is too tight, turnadjusting screw 1/4 turn counterclockwise.
SIf chain is too loose, turn adjusting screw 1/4 turn clockwise.
