9.2 Grinding the safety hood blade
The safety hood blade can become blunt over
time. When you notice this, undo the screw hol-
ding the safety hood blade on the safety hood.
Clamp the blade in a vise. Sharpen the blade with
a fl at fi le and make sure that the angle of the cut-
ting edge is not altered in the process. File in one
direction only.
9.3 Maintenance of the air fi lter (Fig. 31-33)
Soiled air fi lters reduce the engine power by
supplying too little air to the carburetor. Regular
checks are therefore essential. The air fi lter (T)
should be checked after every 25 hours of use
and cleaned if necessary. If the air contains a
lot of dust, the air fi lter should be checked more
frequently.
1. Remove the air fi lter cover (Fig. 31-32).
2. Remove the air fi lter (Fig. 33).
3. Clean the air fi lter by tapping it or blowing it
out.
4. Assemble in reverse order.
Warning! Never clean the air fi lter with petrol or
infl ammable solvents.
9.4 Maintenance of the spark plug (Fig. 34)
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 boot plug (Fig. 13).
2. Remove the spark plug (Fig. 34) with the sup-
plied multifunction tool (27).
3. Assemble in reverse order.
9.5 Carburetor settings
Important! Settings on the carburetor may only
be made by authorized customer service person-
nel.
The air fi lter cover must be removed before car-
rying out any work on the carburetor, as shown in
Fig. 31 and 32.

9.6 Setting the throttle cable
If the maximum speed of the equipment drops
over time and you have ruled out all the other
possible causes listed in section 12 „Troubleshoo-
ting", it may be necessary to adjust the throttle
cable. First of all check whether the carburetor
opens fully when the throttle handle is pressed
right through. This is the case if the carburetor sli-
de (Fig. 41) is completely opened when the thrott-
le is fully activated. Figure 41 shows the correct
setting. If the carburetor slide is not completely
open, it must be adjusted. The following steps are
required to adjust the throttle cable:
Undo the lock nut (Fig. 42/Item C) a few turns.
Turn out the adjusting screw (Fig. 42/Item D) until
the carburetor slide is completely open when the
throttle is fully activated, as shown in Figure 41.
Retighten the lock nut.
9.7 Setting the idling speed
Warning! Set the idling speed when the equip-
ment is warm.
If the engine stalls when the throttle is not pressed
and you have ruled out all the other possible
causes listed in section 12 „Troubleshooting", the
idling speed must be adjusted. To do this, turn
the idling speed screw (Fig. 42/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.
9.8 Applying grease to the gear unit
After every 20 hours of use add a little gear gre-
ase (approx. 10 g.) at the lubrication nipple (Fig.
28/Item 21).
10. Cleaning, storage, transport and
ordering of spare parts
10.1 Cleaning
•
Keep the handles free of oil so that you can
maintain a firm grip.
•
Clean the equipment as required with a damp
cloth and, if necessary, mild washing up
liquid.
Important!
Always pull out the spark boot plug each time
before carrying out any cleaning. Never immerse
the equipment in water or other liquids in order to
clean it.
