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, a lot of the saw's 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 chew up 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.
