• Clean the device at regular intervals using a damp
cloth and a little detergent. Make sure that no water
can penetrate the device interior.
When used as a leaf blower:
• Clean the blast pipe (4) and flat nozzle (1) / round
nozzle (2) with a brush when dirty.
When used as a leaf vacuum:
• After finishing work, remove the collection bag (24),
turn it inside out and clean it thoroughly and dry it if
necessary to prevent mould and unpleasant odours
from developing.
• A heavily soiled collection bag (24) can be washed
with soap and water and then dried.
• If the zip is difficult to operate, rub the zip teeth with
a dry soap bar.
• Clean the vacuum tube (14), suction nozzle (12)
and outlet tube (18) with a brush if they are dirty.
11.2 Maintenance
CAUTION
Always switch off the device and disconnect the spark
plug connector (See 11.2.2 Spark plug maintenance)
before maintenance.
All protective and safety equipment must be reas-
sembled immediately after repair, maintenance is
completed.
11.2.1 Carburettor setting maintenance
If the engine stops by itself when the throttle is re-
leased, a carburettor adjustment must be made.
Have carburettor adjustments (e.g. idle speed adjust-
ment) carried out only by qualified specialists to avoid
engine damage.
11.2.2 Spark plug maintenance (Fig. 14, 15, 16)
1. Remove the spark plug connector cover (24). To
do this, loosen the screw (H). (fig. 14, 15)
2. Pull off the spark plug connector (30).
3. Loosen the spark plug with the enclosed spark
plug wrench (28).
Electrode gap = 0.6 - 0.7 mm (distance between the
electrodes, between which the ignition spark is gen-
erated).
Check the spark plug for dirt and grime after 10 op-
erating hours and if necessary, clean it with a copper
wire brush. Then service the spark plug every 50 op-
erating hours.
4. The re-assembly takes place in reverse order.

11.2.3 Fuel filter maintenance
Inside the fuel tank (22) there is a filter that prevents
impurities from entering the engine. The filter should
be replaced once a year by your dealer.
11.2.4 Air filter maintenance (fig. 14, 17)
Fouled air filters diminish the engine output due to
reduced air supply to the carburettor.
Regular inspection is therefore essential. The air filter
foam insert (31), air filter non-woven insert (32) and
the air filter metal insert (33) should be checked regu-
larly and cleaned if necessary.
If the air is very dusty, check the air filter foam insert
(31), air filter non-woven insert (32) and the air filter
metal insert (33) more frequently.
1. Loosen the air filter screw (26) by turning an-
ti-clockwise.
2. Remove the air filter cover (25).
3. Remove the air filter foam insert (31), air filter
non-woven insert (32) and the air filter metal in-
sert (33).
4. Clean the air filter foam insert (31), air filter
non-woven insert (32) and the air filter metal in-
sert (33) by tapping or blowing them out (with
compressed air).
5. The re-assembly takes place in reverse order.
WARNING
Never clean the air filter foam insert (31), air filter
non-woven insert (32) or the air filter metal insert (33)
with petrol or flammable solvents.
11.3 Important note in the case of repairs:
When returning the device for repair, for safety rea-
sons, ensure that it is free of oil and fuel when it is
sent to the service centre.
11.3.1 Draining the fuel-oil mixture
In case of storage over a longer period of time, the
petrol must be drained.
Only empty the tank outdoors or in well-ventilated
rooms. Make sure that no fuel gets into the soil (envi-
ronmental protection). Use a suitable collection con-
tainer (not included in the scope of delivery).
• Unscrew and remove the tank filler cap (23).
• Carefully pour the fuel-oil mixture from the tank into
a suitable container.
• Drain the fuel-oil mixture completely.
• Screw the tank filler cap (23) back on by hand.
