Use a brush or compressed air to keep the cooling vents of the starter assembly free and clean of debris.
CLEANING THE ENGINE
See Figures 68 and 69.
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 dealer personnel.

CLEANING THE SPARK ARRESTING SILENCER
See Figure 72.
The silencer (A) is equipped with a spark arrester screen (B). A faulty spark arrester screen can create a fire hazard. Through normal use the screen can become dirty and should be inspected weekly and cleaned as required. Always keep the silencer and spark arrester on your saw in good condition.
WARNING
Silencer surfaces are very hot during and after operation of the chainsaw. Keep all body parts away from the silencer. Serious burns may occur if contact is made with the silencer.
1.Allow the silencer to cool.
2.The spark arrester screen (B) is retained by the deflector (C). Remove the nuts (D) and screen retainer to access the spark arrester screen.
3.Replace the spark arrester screen if it is cracked or otherwise deteriorated.
CHAIN BRAKE
See Figures 73 and 74.
■Remove the clutch cover and clean the chain brake components. Check wear on the brake band (A). If brake band is worn or deformed, have it serviced at your nearest authorised service dealer. The band thickness should not be less than 0.60 mm (0.024 in.), or worn halfway through.
■Always keep the chain brake mechanism clean (B) and lightly lubricate the linkage (C).
■Always test the chain brake performance after servicing or cleaning. Refer to “Operation – Operating the Chain Brake” earlier in this manual for additional information.
■Check and, if damaged, replace the chain catcher (D).
