9. Pull the two line ends briefly and powerfully to
release them from the line holders in the line spool.
10. Cut the excess line to a length of around 13 cm.
This will reduce the load on the engine when
starting up and warming up.
11. Fit the line spool again. See section 6.1.6. If you
are replacing the complete line spool, ignore
points 3-6.

8.2 Servicing the air filter

Soiled air filters reduce the engine output by supply
too little air to the carburetor. Regular checks are
therefore essential. The air filter should be checked
after every 25 hours of use and cleaned if necessary.
If the air contains a lot of dust, the air filter should be
checked more frequently.
1. Remove the air filter cover (Fig. 10a).
2. Remove the filter element (Fig. 10b/10c).
3. Clean the filter element by tapping it or blowing it.
4. Assemble in reverse order.
Important: Never clean the air filter with petrol or
inflammable solvents.
8.3 Maintenance of the spark plug
Spark plug sparking gap = 0.6mm. Tighten the spark
plug with a torque of 12 to 15 Nm. Check the spark
plug for dirt and grime after 10 hours of operation and
if necessary clean it with a copper wire brush.
Thereafter service the spark plug after every 50 hours
of operation.
1. Pull off the spark plug boot by twisting.
2. Remove the spark plug (Abb. 11b) with the
supplied spark plug wrench (27).
3. Assemble in reverse order.
8.4 Sharpening the protective hood blade
The protective hood blade may become blunt over
time. If the blade appears to have lost its sharp edge,
unfasten the screw retaining the blade to the
protective hood. Clamp the blade in a bench vise.
Sharpen the blade with a flat file, taking care to
preserve the cutting edge angle. File the blade only in
one direction.
8.5 Carburetor settings
Important. Settings on the carburetor may only be
made by authorized customer service personnel.
The air filter cover must be removed before any work
on the carburetor, as shown in Figures 10a and 10b.

Setting the throttle cable:
If the maximum speed of the machine falls over time
and you have ruled out all the other causes listed in
section 11 Troubleshooting, it may be necessary to
adjust the throttle cable.
First of all check whether the carburetor opens fully
when the throttle handle is pressed fully. This is the
case if the carburetor slide F rests against the stop
(Fig. 13a) when the throttle is fully open. Figure 13a
shows the correct setting. If the carburetor slide does
not touch the stop, it must be adjusted.
The following steps are required to adjust the
throttle cable:
Undo the lock nut (Fig. 13b/Item C) a few turns.
Undo the adjusting screw (Fig. 13b/Item D) until
the carburetor slide F rests against the stop when
the throttle is fully open, as shown in Fig 13.
Retighten the lock nut.
Setting the idling speed
Important. Set the idling speed when the equipment
is warm.
If the engine stalls when the throttle is not pressed
and you have ruled out all the other causes listed in
section 11 Troubleshooting, the idling speed must be
adjusted. To do this turn the idling speed screw (Fig.
13b/Item E) clockwise until the equipment runs
smoothly at idling speed. If the idling speed is so fast
that the cutting tool turns as well, it has to be reduced
by turning the idling speed screw for as long as is
required for the cutting tool to stop turning as well.
8.6 Environmental protection
Dispose of soiled maintenance material and
operating materials at the appropriate collection point.
Recycle packaging material, metal and plastics.
