Correct Chain Tension
With the chain brake
disengaged, pull the
chain through from the
top side and it should
rotate freely without any
slack appearing
If the chain goes from
tight to loose the
sprocket and chain may
not be of the same pitch,
or the sprocket and chain
may have excessive
wear and no longer have
the same pitch

Correct Chain Tension
Regardless of bar
length, check for
correct chain tension
by pulling up on the
chain at the center of
the bar
The tension is correct
when the bottom of the
drive link will just clear
the bar groove
