MAINTENANCE
In addition, lubricate guide bars (with a sprocket at
their tip) weekly. Using a grease syringe, lubricate weekly
in the lubricating hole.
Turn the guide bar and check that the lubrication holes
(
A
) and chain groove are free from impurities.
CLEANING THE AIR FILTER (Fig. 62, 63a, 63b
& 66)
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 cylinder cover (
B
).
2. Activate chain brake.
3. Lift the front of the cylinder cover past chain brake lever.
4. Lift the back of the cylinder 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:
9. To lightly clean, tap the filter against a smooth, flat
surface to dislodge most saw dust and dirt particles.
10. 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).
11. 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 cylinder cover (
B
),
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.
CAUTION
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 (Fig. 65)
Use a brush or compressed air to keep the cooling vents
of the starter assembly free and clean of debris.
CLEANING THE ENGINE (Fig. 66 & 67)
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.
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 recommend
that only qualified service technicians perform this service.
CHECKING THE FUEL FILTER (Fig. 68)
Check the fuel filter (
A
) periodically. Replace it if
contaminated or damaged.
REPLACING THE SPARKING PLUG (Fig. 69)
This engine uses a Champion RCJ-6Y with 0.63 mm
(0.025 in.) electrode gap. Use an ex act 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.
CLEANING THE SPARK ARRESTING
SILENCER (Fig. 70a & 70b)
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.
