E. CLUTCH AND DRUM/SPROCKET

_WARNING

Do not start engine without Guide Bar, Chain, and Bar Clamp Housing completely assembled. The clutch can come off without the guide bar and chain completely assembled and serious injury can result. The clutch shoes and drum can separate causing the clutch to

violently fly apart and serious injury can result.

•Take the saw to a qualified service dealer for full clutch inspection and service after each 100 hours

of operation. It is recommended thatyou do not tryto service the clutch or drum/sprocket yourself unless you

are a competent smal! 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,

slippage occurs during a cut.

--a chattering noise occurs during cutting.

•Clean the clutch, drum, sprocket and surrounding area daily during heavy use of the saw.Check to see that the clutch drum turns freely and smoothly.

•Inspect the sprocket regularly for wear. A worn

,sprocket wilt make the chain run erratically and will shorten the life of the bar and chain. Figure 41.

•Always have a worn sprocket replaced, by a qualifed service dealer whenever a new chain is installed in order to gain the full life expectancy of the chain.
