plug connector
.
■
Clean the tool regularly with a damp cloth and a mild detergent.
Make sure that no water can penetrate into the interior of the tool.

Maintenance
Replacing the strimmer/cutting filament
1.) The strimmer
must be removed as described in section "Installing/
replacing the strimmer". Press the marking (see Fig. 4a) and remove the
cover (see Fig. 4b).
2.) Remove the spool bobbin
3.) Remove any remaining cutting filament.
4.) Double the new cutting filament and hook the loop that you have made
into the recess on the spool bobbin (see Fig. 4d).
5.) Wind the filament tightly in an anticlockwise direction. The spool
bobbin
separates the two halves of the cutting filament (see Figs.
4e and 4f).
6.) Now take the cover in your hand and place the spool bobbin
Make sure that the filament holder of the spool bobbin lines up with the
filament guide on the cover.
7.) Now release the cutting filament from the spool bobbin
it through the metal eyes in the cover.
8.) Put the two halves of the housing back together until they click into
place.
9.) Cut any excess filament back to about 13 cm. This reduces the load on
the engine during start-up and while warming up.
10.) Refit the strimmer (see section "Installing/replacing the strimmer").

Air filter maintenance
Contaminated air filters reduce engine performance due to low air supply
to the carburettor.
Regular inspection is essential. The air filter must be inspected after every
25 hours of operation and cleaned if necessary.
The air filter must be checked more frequently if you are working in dusty
environments.
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.
ATTENTION!
■
Never clean the air filter with petrol or flammable solvents.
Spark plug maintenance
1.) Pull off the spark plug connector
2.) Unscrew the spark plug using the supplied spark plug wrench
and
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.
Grinding the protective guard blade
The blade
(see Fig. 2a) can become blunt over time. If you notice this

blade
with a sharpening stone and make sure you maintain the angle

of the cutting edge.
Adjusting the carburettor
■
Carburettor adjustments should only be carried out by qualified
personnel, the manufacturer or its service department.
Lubricating the gears
■
Add 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 gearbox casing.
♦
After filling the gearbox, close the lubrication hole with the screw
in it.
