CLEANING THE ENGINE
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
drive case 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 dealer personnel.
CLEANING THE STARTER UNIT
Use a brush or compressed air to keep the cooling vents of
the starter assembly free and clean of debris.
CHECKING THE FUEL FILTER
Check the fuel filter periodically. Replace it if contaminated or
damaged.

REPLACING THE SPARKING PLUG
This engine uses a Champion RCJ-4 with 0.63 mm
(0.025 in.) electrode gap. Use an exact replacement and
replace every six months, or more frequently if necessary.
1. Loosen the sparking plug by turning it anticlockwise with
a spanner.
2. Remove the sparking plug.
3. Hand thread the new sparking plug, turning it clockwise.
NOTE: Be careful not to cross-thread the sparking 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 silencer may become blocked with carbon
deposits. If you notice a power loss with your petrol-
powered tool, you may need to remove these deposits to
restore performance. We highly recommended that only
qualified service technicians perform this service.
