C, CHAIN TENSION
• Correct Chain Tension is veiy im^rtant—
- A loose chain will wear the bar and itself.
- A loose chain can jump off the bar while you are
cutting
- A tight chain can break or damage the saw and/
or bar.
• Hie chain stretches during use, especially
when new. Check tension periomcally as follows:
- each time the saw is used;
- more frequently when the chain is new,
- as the ch^ warms up to normal operating
temperature.
• Chain tension is correct when the chain:
- can be lifted about 1/8'’ fix»m tbe Guide Bar at a
point near the middle of the bar and
- will move freely around the bar.

be lifted 1/4” from the ban Thei^after, follow the
instructions as indicated.
