HOW TO TENSION YOUR CHAIN WITHOUT INTENZ™
If you have a sprocket-nose bar
Tension must be tighter than on a solid-nose bar. Turn your saw's

tension-adjustment screw until the bottoms of the lowest tie straps
and cutters come up and solidly contact the bottom of the bar rail.
➎
With either type of bar, hold the nose up and tighten your saw's rear
bar-mounting nut first, then tighten the front nut.
➏
Pull the chain by hand along the top of the bar several times,
from the engine to the bar's tip. Chain should feel snug but still pull
freely.
NOTE: If you have a sprocket-nose bar you should now perform the snap
test. Grasp the chain along the bottom of the bar, pull down, and let go.
Chain should snap back to its original position, solidly contacting the
bottom of the bar.
➐
Check tension often during operation, especially during the first
half-hour. If chain loosens: stop, let chain cool, and readjust ten-
