The air fi lter must be checked more frequently if the air is dusty.
1.) Remove the air fi lter housing cover
2.) Remove the air fi lter
3.) Clean the air fi lter
4.) Assembly takes place in reverse order.
IMPORTANT!
■
Never clean the air fi lter with petrol or fl ammable solvents.
Spark plug maintenance
GB
MT
1.) Remove the spark plug connector
2.) Remove the spark plug using the enclosed spark plug spanner
3.) Assembly takes place in reverse order.
Electrode gap = 0.6 mm (distance between the electrodes between which
the ignition spark is generated). Tighten the spark plug with 12 to 15 Nm
of torque using a torque wrench (available from specialist retailers).
Initially check the spark plug for contamination after 10 hours of operation
and clean this with a copper wire brush if required.
Then service the spark plug after every 50 hours of operation.
Grinding the protective hood blade
The protective hood blade
If you notice that this is the case, loosen the 2 screws used to fasten the
protective hood blade
the blade in a vice. Grind the blade with a grindstone and ensure that the
correct angle of the blade edge is maintained. Only grind in one direction.

Adjusting the throttle cable
If the device's maximum speed is no longer reached over time and all
other causes in accordance with the "Troubleshooting" section have been
ruled out, this may mean that the throttle cable needs to be adjusted.
NOTE
■
First check whether the carburettor opens completely when the throttle
lever is fully engaged.
This is the case if the carburettor slide (see fi g. 13b) is completely open at
full throttle. Figure 13a shows the correct setting. An adjustment is necessary
if the carburettor slide is not fully open.
The following steps must be taken to adjust the throttle cable:
■
Loosen the locking nut
justing screw
(see fi g. 13a) until the carburettor slide is completely
open at full throttle (see fi g. 13b).
■
Retighten the locking nut

Adjusting the idling rate
IMPORTANT!
■
Adjust the idling rate once the device has warmed up.
If the device does not come to a stop when the throttle is not engaged
and all other causes in accordance with the "Troubleshooting" section
have been excluded, it may mean that a readjustment of the idling rate is
required. Rotate the idling screw
until the device idles smoothly. If the idling rate is so high that the cutting
tool rotates, this must be reduced by turning the idling screw to the left until
the cutting tool no longer rotates.

Lubricating the gears
■
Add gear grease after every 20 hours of operation (approx. 10 g).
To do so, open the screw

Storage and transportation
■
Store the device in a safe location.
■
Store the device and accessories in a safe location that is protected
against naked fl ames and sources of heat/sparks, such as gas-powered
water heaters, dryers, oil stoves or mobile heaters, etc.
■
Always keep the cutting blade protective hood
and the engine free of mowing residue during storage.
■
Always turn the device off before performing any maintenance work
and remove the spark plug connector
Storing the device
The device 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 rubbery sediment. This may make starting the device more diffi cult
and result in expensive repair work.
1.) Remove the fi ller cap in order to relieve any pressure in the fuel tank
Carefully empty the fuel tank
2.) Start the engine and leave it to run until it stops in order to remove all
fuel from the carburettor.
3.) Allow the engine to cool for about 10 minutes.
4.) Remove the spark plug (see "Spark plug maintenance" chapter).
5.) Add 1 teaspoon of 2-stroke oil to the combustion chamber. Pull the
starter pull cord
with oil. Re-insert the spark plug.
NOTE
■
Store the device in a dry place and away from possible ignition
sources.
