• Chain tenslonis very Important:
--A loose chain will wear the bar and itself.
•_A loose chain can jump off the bar while you are
cutting
L- A tight chain can damage the saw andlor break.
• Chain tension is correct when the chain:
_-; can be liffedabout 1t8" from the Guide Bar at a
point near the middle of the bar, and
wi!l move freely around the bar.
• The Bar Clamp Nuts must be loosened to propedy
tension the chain.
• The chain stretches during use, especial|y 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.
