Chain tenslonis very Important:
--A loose chain will wear the bar and itself.
_A loose chain can jump offthe bar whileyou 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 isnew
_as the chain warms up to normal operating
temperature.
