7.2.2 Air filter
Warning: Never operate saw without the air
filter. Dust and dirt will be drawn into engine and
damage it. Keep the air filter clean! The air filter must
be cleaned or replaced after every 20 hours of
service.
Cleaning the air filter (Fig. 18A/18B)
1. Remove the top cover (A) by undoing the cover
fastening screw (B) on the cover. You can then
remove the cover (Fig. 18A).
2. Lift out the air filter (C) (Fig. 18B).
3. Clean air filter. Wash filter in clean, warm, soapy
water. Rinse in clear, cool water. Air dry
completely.
Note: It is advisable to have a supply of spare filters.
4. Insert the air filter. Fit the cover for the engine/air
filter. Make sure that the cover fits perfectly when
you do so. Tighten the fastening screw for the
cover.
7.2.3 Fuel filter
Warning:Never use the saw without a fuel filter.
After 100 hours in operation the fuel filter should be
cleaned or, in case of damage, replaced. Be sure to
empty the fuel tank before changing the filter.
1. Remove the fuel tank cap.
2. Bend a piece of soft wire.
3. Reach into fuel tank opening and hook fuel line.
Carefully pull the fuel line toward the opening until
you can reach it with your fingers.
Note: Do not pull hose completely out of tank.
4. Lift filter (A) out of tank (Fig. 19).
5. Pull off the filter with a twist and clean it; if the
filter is damaged, dispose of it.
6. Insert a new filter. Place one end of the filter into
the tank opening. Make sure that the filter is
seated in the lower corner of the tank. If
necessary, use a long screwdriver to move the
filter to its correct position, taking care not to
damage in the process.
7. Fill tank with fresh fuel / oil mixture. See Section
Fuel and Lubrication. Install fuel cap.
7.2.4 Spark plug (Fig. 18B)
Warning: To ensure that the saw’s engine retains
its power, the spark plug must be clean and have the
correct electrode gap (0.6 mm). The spark plug must
be cleaned or replaced after every 20 hours of
service.
1. Set the On/Off switch to Stop (0)”.
2. Remove the top cover (A) by undoing the cover
fastening screw (B) on the cover. You can then
remove the cover (Fig. 18A).
3. Disconnect the ignition cable (D) from the spark
plug by pulling and twisting it simultaneously (Fig.
18B).
4. Remove the spark plug using a spark plug
wrench. DO NOT USE ANY OTHER TOOLS.
5. Clean the spark plug with a copper wire brush or
fit a new one.
7.2.5 Carburetor setting
The carburetor has been set to its perfect adjustment
at the factory. If it requires adjusting, take the saw to
your nearest authorized after-sales service outlet.
7.2.6 Chain bar maintenance
Regular lubrication of the chain bar (guide rail for the
chain and teeth) is essential. The chain bar needs the
maintenance described in the following section in
order for the saw to work at an optimum level of
performance.
Caution: The sprocket tip on your new saw has
been pre-lubricated at the factory. Failure to lubricate
the guide bar sprocket tip as explained below will
result in poor performance and seizure, voiding the
manufacturer’s warranty.
Tools for lubrication
The Lube Gun (optional) is recommended for
applying grease to the guide bar sprocket tip. The
Lube Gun is equipped with a needle nose tip which is
necessary for the efficient application of grease to the
sprocket tip.
To lubricate sprocket tip
Lubrication of the sprocket tip is recommended after
10 hours of use or once a week, which ever occurs
first. Always thoroughly clean guide bar sprocket tip
before lubrication.
Note: The saw chain does not have to be removed in
order to lubricate the teeth of the chain bar.
Lubrication is possible during work, with the engine
switched off.
Warning: Wear heavy duty work gloves when
handling the bar and chain.
1. Set the On/Off switch to Stop (0)”.
2. Clean the guide bar sprocket tip.
3. Using the Lube Gun (optional), insert needle nose
into the lubrication hole and inject grease until it
appears at outside edge of sprocket tip (Fig .20).
