E. CLUTCH AND DRUM/SPROCKET F. AIR FILTER
^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.
i Take the saw to a qualified service dealer for full
clutch Inspection and service after each 100 hours
of operation.
It is recommended that you do not try to
service the clutch or drum/sprocketyourself untessyou
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.
— slippage occurs during a cut.
— a chattering noise occurs during cutting.
Clean the clutch, drum, sprocket and surrou nding
area daily during heavy use of the saw.
Check to see
that the clutch drum turns freely and smoothly,
t Inspect the sprocket regularly for wear. A worn
sprocket will 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.
• A dirty air filter:
— reduces cutting power
— increases fuel consumption
• Clean the air filter:
—frequently, especially in very dusty conditions,
— always after 10 tanks of fuel mixture or 5 hours
of operation, whichever is less.
• Replace the air filter if any damage occurs to it.

ways:
1. Drain fuel tank in a safe manner. See “Fueling Your
Engine.”
2 Start engine and allow to run at idle speed until the
engine stops.
NOTE: This will remove most of the fuel from the
fuel system.

dling the chain. The chain is sharp and can cut
you even when it is not moving.
3. Drain oil tank.
4. Remove, clean, and dry the bar and chain.
