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 6.1.8. 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 (37) 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. 12a/Pos. 36).
2. Remove the filter element (Fig. 12b/Pos. 37).
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 (Fig. 13)
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 out the spark plug connector (38).
2. Remove the spark plug (39) with the supplied
spark plug wrench (20).
3. Assemble in reverse order.
8.4 Grinding the safety hood blade
The safety hood blade can become blunt over time.
When you notice this, undo the two screws holding
the safety hood blade to the safety hood. Clamp the
blade in a vise. Sharpen the blade with a flat file and
make sure that the angle of the cutting edge is not
altered in the process. File in one direction only.
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 12a and 12b.
Setting the throttle cable
If the maximum speed of the equipment 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 (Fig. 13a) is completely
opened when the throttle is fully activated.
Figure 13a shows the correct setting. If the carburetor
slide is not completely open, it must be adjusted.
The following work is required to adjust the throttle
cable:
Undo the lock nut (Fig. 13a/Item C) a few turns.
n
Undo the adjusting screw (Fig. 13a/Item D) until
n
the carburetor slide is completely open when the
throttle is fully activated, as shown in Figure 13a.
Retighten the lock nut.
n
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.
13a/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.
8.7 Ordering replacement parts
Please provide the following information on all orders
for spare parts:
Model/type of the equipment
n
Article number of the equipment
n
ID number of the equipment

9. Storage and transport

9.1 Storage
Important: Never put the equipment into storage for
longer than 30 days without carrying out the following
steps.
Storing the equipment
If you intend to store the equipment for longer than 30
days, the equipment must be prepared accordingly.
Otherwise the fuel still remaining in the carburetor will
evaporate and leave a rubbery sediment. This can
cause problems when starting up the equipment and
may require expensive repairs.
1. Slowly remove the fuel tank cap to release any
