clutch to violently fly apart and serious personal injury
can result.

Take the saw to a qualified service
dealer for full clutch inspection and service after
each 100 hours of operation,
/t is recommended
that you do not try to service the clutch or
drum/sprocket yourself unless you are a competent
small engine mechanic and have the proper clutch
service tools.
Proper disassembly and repair of the
clutch is extremely important to the life of the engine
and the safety of the operator.
» Clutch maintenance is required when:
—the chain continues to turn while engine idles
after the idle speed screw has been adjusted
to its capacity,
— slippage occurs during a cut.
—a chattering noise occurs during cutting.
•
Clean the clutch, drum/sprocket and surround-
. ing area daily during heavy use of the saw.
^ Check to see that the clutch drum turns freely and
smoothly.
i Inspect the drum/sprocket regularly for wear.
A
worn sprocket will make the chain run erratically
and will shorten the life of the bar and chain. Figure
