7. Cleaning, maintenance, storage and
ordering of spare parts
Switch off the motor and pull the spark plug boot
from the spark plug before doing any cleaning and
maintenance work on the equipment.
Important: Switch off the machine immediately
and contact your service station:
In the event of unusual vibrations or noise
If the engine appears to be overloaded or
misfires
7.1 Cleaning
Keep all safety devices, air vents and the motor
housing free of dirt and dust as far as possible.
Wipe the equipment with a clean cloth or blow it
with compressed air at low pressure.
We recommend that you clean the device
immediately each time you have finished using it.
Clean the equipment regularly with a moist cloth
and some soft soap. Do not use cleaning agents
or solvents; these could attack the plastic parts
of the equipment. Ensure that no water can seep
into the device.
7.2. Air filter (Fig. 5/6)
The air filter should be cleaned after every 30
hours of operation.
Remove the air filter cover (Fig. 5).
Remove the filter element (Fig. 6).
Clean the filter element with soapy water, rinse
with clear water and leave to dry well before re-
installing.
Assemble in reverse order
7.3. Spark plug (Fig. 7)
Check the spark plug for dirt and grime after 10
hours of operation and if necessary clean with a
copper wire brush. Thereafter service the spark plug
after every 50 hours of operation.
Pull off the spark plug boot with a twist.
Remove the spark plug with the supplied spark
plug wrench.
Assemble in reverse order

7.5 Storage
Please note: If you fail to follow these instructions
correctly, deposits may form on the interior of the
carburetor which may result in the engine being more
difficult to start or the machine suffering permanent
damage.
1. Carry out all the maintenance work.
2. Drain the fuel out of the tank (use a conventional
plastic petrol pump from a DIY store for this
purpose).
3. When the fuel has been drained, start the
engine.
4. Allow the engine to run at idling speed until it
stops. This will clean the remainder of the fuel
out of the carburetor.
5. Leave the machine to cool (approx. 5 minutes).
6. Remove the spark plug (see point 7.3).
7. Place a teaspoon full of 2-stroke engine oil into
the combustion chamber. Pull the starter cable
several times carefully to wet the internal
components with the oil. Fit the spark plug again.
8. Clean the exterior housing of the machine.
9. Store the machine in a cold, dry place where it is
out of the reach of ignition sources and
inflammable substances.
Fertilizers and other chemical garden products often
contain substances that accelerate the rate of
corrosion of metals. Do not store the machine on or
near fertilizers or other chemicals.
Restarting
1. Remove the spark plug.
2. Pull the starter cable several times to clean the
oil residue out of the combustion chamber.
3. Clean the spark plug contacts or fit a new spark
plug.
4. Fill the tank.
Transport
To transport the machine, first empty the petrol tank
as described in section 2 in the section entitled
"Storage". Clean coarse dirt off the machine with a
brush or hand brush.
