NOTE: Always clean the air filter before making any
mixture adjustments of the carburettor.
1. For access to the air filter and carburettor area, loosen
the three screws (A) holding the engine cover (B).
2. Activate chain brake.
3. Lift the front of the engine cover past chain brake lever.
4. Lift the back of the engine cover past the handle.
5. Before removing the air filter from the carburettor, blow
or brush as much loose dirt and sawdust from around
the carburettor and chamber as possible.
NOTE: Be sure to pull the choke rod out to keep the
carburettor from being contaminated.
6. Remove the screw (C) securing the air filter (D).
7. Position a flat screw driver between the tabs and twist
as shown in the illustration.
8. Lift the air filter off the air filter base.
Choose one of the following cleaning options:
● To lightly clean, tap the filter against a smooth, flat
surface to dislodge most of the saw dust and dirt
particles.
● For a more thorough cleaning, clean in warm
soapy water, rinse, and let dry completely.
NOTE: An alternative method is to clean the filter with
compressed air (always wear eye protection to avoid
eye injury).
9. Reinstall the air filter, making sure that the tabs on the
air filter are located in channels on the air filter bottom
before tightening filter retainer screw. Clean the pre-
filter (D) every 25 tanks of fuel or sooner, if required.
Remove the engine cover (3), starter assembly (E)
and the fan housing baffle (F) for access to the pre-
filter in the engine housing.
NOTE: If you use an air hose for drying, blow through
both sides of filter.
WARNING
Never run the engine without the air filter, serious
damage could result. Make sure the air filter is correctly
placed in the air filter cover before reassembly.
CLEANING THE STARTER UNIT
See figure 65.
Use a brush or compressed air to keep the cooling vents
of the starter assembly free and clean of debris.
CLEANING THE ENGINE
See figure 66 - 67.
Clean the engine fins and flywheel fins with compressed
air or a brush periodically. Dangerous overheating of the
engine may occur due to impurities on the engine.
English (Original instructions)
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.
NOTE: Depending on the type of fuel used, the type and
amount of lubricant 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 recommend
that only qualified service technicians perform this service.
