D. CHAIN TENSION
• Chain tension is very important:
a loose chain wilt 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.
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 1/8” from the Guide
Bar at a point near the middle of the bar,
and will move freely around the bar.
• Chain tensioning procedure:
CAUTION: Always wear gloves when handling
the chain. The chain is sharp and can cut you even
when it is not moving.
NOTE:The Bar Clamp Nut must be slightly loose for
the chain to be properly tensioned.
1. Hold the tip of the Guide Bar up and turn the
Adjusting Screw clockwise just until the chain does
not sag beneath the Guide Bar. Figure 11.
2. Check the tension by lifting the chain from the
Guide Bar at the center of the bar. Figure 12.
3. Continue adjusting the Adjusting Screw until
the tension is correct.
4. Hold the tip of the Guide Bar up and tighten
the Bar Clamp Nut with a 1/2 inch Wrench.
5. Check the Rear Bar Clamp Screw to be sure
it is secure.
