CLEANING THE ENGINE

See Figures 67 - 68.

Clean the cylinder fins and flywheel fins with

compressed air or a brush periodically. Danger-

ous overheating of the engine may occur due to

impurities on the cylinder.

WARNING

Never run the saw without all the parts, including

the clutch cover and starter housing, securely

in place.

Because parts can fracture and pose a danger

of thrown objects, leave repairs of the flywheel

and clutch to factory trained authorized service

center personnel.

NOTE:

If you notice a power loss with the gas-

powered tool, the exhaust port and muffler may

be blocked with carbon deposits. These deposits

may need to be removed to restore performance.

We highly recommend that only qualified service

technicians perform this service.

CHECKING THE FUEL FILTER

See Figure 69.

Check the fuel filter periodically. If contaminated or

damaged, have fuel filter replaced by an authorized

service center.

REPLACING THE SPARK PLUG

See Figure 70.

This engine uses a Champion RCJ6Y with .025 in.

electrode gap. Use an exact replacement and

replace every 50 hours or more frequently, if

necessary.

Loosen the spark plug by turning it counter-

clockwise with a wrench.

Remove the spark plug.

Hand thread the new spark plug, turning it

clockwise. Tighten securely with wrench.

NOTE: Be careful not to cross-thread the spark

plug. Cross-threading will seriously damage the

cylinder.
