Checking the tension:
Use the screwdriver end of the chain adjust-
ment tool (bar tool) to move the chain around
the bar. If the chain does not rotate, it is too
tight. If too loose, the chain will sag below the
bar.

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 chain brake
nuts and turning the adjusting screw 1/4 of a
turn while lifting up on the bar.
