Cleaning and replacing the
spark plug
Check the electrode gap on the spark plug
every year, or if the engine does not run
properly or is difficult to start. The electrode
gap should be 0.63 mm.
1. Wait until the engine has cooled.
2. Release the spark plug lead from the
spark plug and unscrew the spark plug
with the supplied spanner.
3. Replace the spark plug with a new one
of the same type if the electrodes are
corroded or burnt, or if there are excessive
deposits on the electrodes.
4. Deposits on the spark plug can be a result
of too much oil in the fuel mixture, poor
quality of oil, old fuel mixture, or blocked
air filter.
5. Carefully screw in the spark plug by hand
to avoid threading problems.
6. Tighten the spark plug with a spark plug
spanner.
7. If a torque wrench is used, tighten to
12–15 Nm.
8. Connect the spark plug lead to the spark
plug.

Cleaning the air filter
The engine will not work properly if the air
filter is blocked because of the reduction in
the supply of air to the carburettor. The foam
plastic filter unit can get blocked by dust and
pollen, etc. Check the filter at regular intervals.
1. Release the filter cover and remove the
foam plastic filter unit.
2. Replace the filter cover to prevent any
thing getting into the air intake.
3. Wash the filter unit in hot water and a
mild detergent, and allow to dry.
NOTE:
• Never use petrol or flammable solvents
to clean the filter.
• Always replace a damaged air filter,
otherwise the engine can be damaged.
WARNING!
Do not start the engine without an air filter.
Cleaning the fuel filter
There is a fuel filter in the fuel tank to prevent
impurities getting into the engine. Hand in the
machine to have the filter replaced every year.
Adjusting the idling speed
The idling speed must be adjusted if the engine
keeps stopping, or if the speed cannot be
controlled with the throttle lever.
1. Start the engine and run on idle for a few
minutes. Now adjust the idling speed with
the screw (A).
FIG. 10
2. Turn clockwise to increase the engine
speed.
3. Turn anticlockwise to reduce the engine
speed.
4. The engine should idle smoothly after
adjusting.
Emptying the fuel tank
The fuel tank should be emptied before putting
the leaf blower away for a long time. Empty
outdoors, or in a well-ventilated area. Allow the
engine to cool completely before emptying the
fuel tank. Use a suitable underlay, and make
sure fuel or oil does not get into the ground.
1. Place a suitable container under the fuel
tank.
2. Unscrew the fuel cap.
