CLEANING THE ENGINE
See Figures 74 and 75.
Clean the cylinder fins and flywheel fins with compressed
air or a brush periodically. Dangerous overheating of the
engine may occur due to impurities on the cylinder.
WARNING
Never run the saw without all the parts, including the
drivecase 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 trained Homelite Service Center personnel.
CLEANING THE STARTER UNIT
See Figure 73.
Use a brush or compressed air to keep the cooling vents
of the starter assembly free and clean of debris.
CHECKING THE FUEL FILTER
See Figure 76.
Check the fuel filter periodically. Replace it if contaminated
or damaged.
REPLACING THE SPARK PLUG
See Figure 77.
This engine uses a Champion RCJ-4 with .025 in. (0.63
mm) electrode gap. Use an exact replacement and replace
every six months or more frequently, if necessary.
1. Loosen the spark plug by turning it counterclockwise
with a wrench.
2. Remove the spark plug.
3. Hand thread the new spark plug, turning it clockwise.
Note: Be careful not to cross-thread the spark plug.
Cross-threading will seriously damage the product.
Note: Depending on the type of fuel used, the type and
amount of oil used, and/or your operating conditions, the
exhaust port and muffler may become blocked with
carbon deposits. If you notice a power loss with your gas
powered tool, you may need to remove these deposits to
restore performance. We highly recommended that only
qualified service technicians perform this service.
