8.3 Maintenance of the spark plug

Electrode gap = 0.6 mm (distance between the
electrodes between which the ignition spark is
created). Tighten the spark plug with 12 to 15 Nm
using a torque wrench (available from your dea-
ler). 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. Dismantle the protective cap (Fig. 10c/Item
31) using a screwdriver.
2. Pull off the spark boot plug (Fig. 1 1a/Item
36).
3. Remove the spark plug (Fig. 1 1b) with the sup-
plied spark plug wrench (27).
4. Assemble in reverse order.
8.4 Sharpening the guard hood blade
The guard hood blade (Fig. 7a/Item F) can be-
come blunt over time. If you notice this, undo the
two screws holding the guard hood blade to the
guard hood. Clamp the blade in a vise. Sharpen
the blade with a fl at fi le and make sure that the
angle of the cutting edge is not altered in the pro-
cess. File in one direction only.
8.5 Carburetor settings
Important: Settings on the carburetor are allo-
wed to be made by authorized customer service
personnel.
The air fi lter housing 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 equipment drops
over time and you have ruled out all the other
possible causes listed in the section „Troubleshoo-
ting", it may be necessary to adjust the throttle
cable.
First of all check whether the carburetor opens ful-
ly when the throttle lever is pressed right through.
This is the case if the carburetor slide (Fig. 13a/
Item F) is completely opened when the throttle is
fully activated.
Figure 13a shows the correct setting. If the car-
buretor slide is not completely open, 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 is completely open
when the throttle is fully activated, as shown in
Figure 13a.
•
Retighten the lock nut.
Setting the idling speed:
Caution! 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 the section „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 Applying grease to the gear unit
Add a little gear grease (approx. 10 g) after
every 20 hours in operation. To do so, open the
screw H (Fig. 7c).

8.7 Environmental protection

Dispose of soiled maintenance material and
operating materials at the appropriate collection
point.
Recycle packaging material, metal and plastics.
