TENSION
• Chain tension is very important:
-- a loose chain will wear the bar and itself.
u a loose chain can jump off the bar while you
are cutting.
--a
tight chain can break or damage the saw
and/or bar.
• The chain stretches during use, especially
when new, Check tension.."
each time the saw is used
more frequently when the chain is new
-- as the chain warms up to normal operating
temperature.
• Chain tension is correct when the chain:
can be lifted about 118" from the Guide
Bar at a point near the middle of the bar,
and will move freely around the bar.
