when the chain brake nuts are tight can
cause damage.

ment toot (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. Iftoo loose, the chain will sag below the
bar.

use and refuel your saw> You can adjust the
chain tension by loosening the chain brake
nuts and turning the adjusting screw 1/4 of a
turn while lifting up on the bar.
• If chain is too tight, turn adjusting screw 1/4
turn counterclockwise.
• If chain is too loose, turn adjusting screw
1/4 turn clockwise.
