Air filter maintenance
Contaminated air filters reduce the engine performance due to low air
supply to the carburettor.
Regular inspection is essential. The air filter
every 25 hours of operation and cleaned if necessary.
The air filter must be checked more frequently if the air is dusty.
1.) Remove the cover of the air filter housing
2.) Remove the air filter
.
3.) Clean the air filter
by tapping or blowing it out (with compressed
air).
4.) Assembly is done in the reverse order.
CAUTION!
■
Never clean the air filter with petrol or flammable solvents.
Spark plug maintenance
1.) Pull off the spark plug connector
2.) Remove the spark plug using the enclosed spark plug spanner
3.) Assembly is done in the reverse order.
Electrode gap = 0.6 mm (distance between the electrodes between which
the ignition spark is generated). Check the spark plug for contamination
after the first 10 hours of operation and clean it with a copper wire brush
if required.
Afterwards, service the spark plug after every 50 hours of operation.

Adjusting the carburettor
Remove the cover of the air filter housing
Adjusting the throttle cable
If the appliance no longer reaches maximum speed after a while and all
other causes as described in the "Troubleshooting" section have been ruled
out, this may mean that the throttle cable needs to be adjusted. To adjust
the throttle cable, screw in the screw

correctly (see Fig. 4).
Lubricating the gears
■
Add liquid gear grease after every 20 hours of operation (approx.
10 g) to lubricate the angle gear.
♦
To do this, undo the screw
grease into the gear housing.
♦
After filling the gearbox, close the lubrication hole with the screw

Storage and transportation
■
Store the appliance in a safe location.
■
Store the appliance and accessories in a safe location which is pro-
tected against naked flames and sources of heat/sparks, such as gas-
powered water heaters, dryers, oil stoves or mobile heaters, etc.
■
Ensure that the protective guard
free of cutting residue when storing.

Always turn the appliance off before performing any maintenance work
and remove the spark plug connector
Storing the appliance
The appliance must be prepared for storage if it is to be stored for longer
than 30 days. Otherwise the residual fuel in the carburettor will evaporate
and leave a gooey sediment. This may make starting the appliance more
difficult and result in expensive repair work.
1.) Remove the filler cap
Carefully empty the fuel tank
.
2.) To remove all fuel from the carburettor, start the engine and leave it to
run until it stops.
3.) Allow the engine to cool for about 10 minutes.
4.) Remove the spark plug (see section "Spark plug maintenance").
5.) Add 1 teaspoon of 2-stroke oil to the combustion chamber. Pull the
starter pull cord
Replace the spark plug.
NOTE
■
Store the appliance in a dry place and away from possible ignition
sources.
Start-up after storage
1.) Remove the spark plug (see section "Spark plug maintenance").
2.) Pull the starter pull cord
from the combustion chamber.
3.) Clean the spark plug and observe the correct electrode gap on the
spark plug.
4.) Fill the fuel tank
. See the section "Fuel and oil".
Transport
■
If you are planning to transport the appliance, empty the fuel tank
as explained in the section "Storage".
