9.3 Maintenance of the air fi lter
Soiled air fi lters reduce the engine output by sup-
ply too little air to the carburetor. Regular checks
are therefore essential. The air fi lter 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. 10a).
2. Remove the fi lter element (Fig. 10b/10c).
3. Clean the fi lter element by tapping it or
blowing it.
4. Assemble in reverse order.
Important: Never clean the air fi lter with petrol or
in fl ammable solvents.
9.4 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 o ff the spark plug boot by twis-
ting.
2. Remove the spark plug (Abb. 11b) with the
supplied spark plug wrench (27).
3. Assemble in reverse order.
9.5 Carburetor settings
Important. Settings on the carburetor may only be
made by authorized customer service personnel.
The air fi lter 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 12 Troubleshooting, it may be ne-
cessary 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 car-
buretor 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.
9.6 Setting the idling speed
Important. 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 cau-
ses 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 cut-
ting tool to stop turning as well.
9.7 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.
Store the equipment in a safe and dry place out of
the reach of children.
10.2 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.
