CORRECT CHAIN TENSION
All chains have a tendency to stretch
when used. Diamond chains stretch
more than wood cutting chains
because of the abrasive materials
they are cutting.
If the chain is too tight, more power
goes into turning the chain rather
than into the cut. In extreme
over-tightened cases, the saw
may not be able to turn the chain
at all. In addition, damage can occur
to the bar nose and premature
stretch may occur.
CHAIN TOO LOOSE
If the chain is too loose, it could come
off the bar, or it will allow the drive
sprocket to spin without turning the
chain, which can damage drive links.
When a chain stretches to a point
where the drive links are hanging
approximately 1/2 in (12 mm) to 3/4
in (18 mm) below the bar, it is time to
tension the chain.
