• A dirty air filter:
— ]*educes cutting power.

— check filter after every 10 tanks of fuel or 5
hours of operation, whichever is less.
— more frequently in veiy dusty conditions.
Clean off carburetor cover and the area around it.
Move the choke to the full position to prevent dirt
from entering the carburetor.

F. CLUTCH AND DRUM/SPROCKET
A WARNING
Do not start the engine without the guide bar,
chain, and bar clamp housing comjdetely as-
semhledU 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 violent-
ly fly apart and serious injury can result.
Take the saw to your Authorized Service
Dealer for full clutch inspection and service
after each 100 hours of operation. It is recom-
mended that you do not try to service the dutch or
drum!^rocket 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 en­
gine and the safety of the operator.
Inspect the sprocket regularly for wear. A
worn sprocket will make the chain run erraticedly
and will shorten the life of the bar and chain. Fig­
ure 39 .
Clutch maintenance is required when:
— the chain continues to turn while the 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 sur­
rounding area daily during heavy use of the
saw. Check to see that the clutch drum turns freely
and smoothly.
Always have a worn sprocket replaced by
your Authorized Service Dealer whenever a
new chain is installed to gain the full life expec­
tancy of the chain.

G. STORAGE
When your saw is to be stored for over 30 days,
always:
1. Drain fuel tank in a safe manner. See “Fueling Your
Engine—Fuel Safety.”
Start engine and aUowto run at idle speed until the
engine stops.
NOTE; Running the engine until it stops will re­
move most of the fuel from the fuel system.
NOTE: It is important to prevent gum deposits
from forming in essential fuel sTCtems parts such as
the carburetor, fuel filter, fuel hose, or tank during
storage. Alcohol blended fuels (c^ed gasohol or
using ethanol or methanol) can attract moisture
vdiicn leads to separation and formation of acids
during storage. Acidic can damage the fuel sys­
tem of an engine while in storage.
3. Drain oil from oil tank.

cut you even when it is not moving.
4. Remove, clean, and dry the bar and chain.
5. Store the chain in a container filled with oil to pre­
vent rust,
6. Apply a coating of oil to the entire surface of the bar
and wrap it in heavy paper, cloth, or plastic.
7. Clean the outside surface of the engine.
8. Store the saw in a diy place, out of the reach of chil­
