9.5 Carburetor settings
Warning! 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 12a
and 12b.
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
slide (Fig. 13a) is completely opened when the
throttle is fully activated. Figure 13a shows the
correct setting. If the carburetor slide is not com-
pletely open, it must be adjusted. The following
steps are required to adjust the throttle cable:
•
Undo the lock nut (Fig. 13a/Item C) a few
turns.
•
Undo the adjusting screw (Fig. 13a/Item D)
until the carburetor slide is completely open
when the throttle is fully activated, as shown
in Figure 13a.
•
Retighten the lock nut.

9.6 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. 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.
The start-up speed of the cutting tool must be at
least 1.25 times the idling speed.
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.
1. Slowly remove the fuel tank cap to release
any pressure that may have formed in the
tank. Carefully empty the tank.
2. To remove the fuel from the carburetor, start
the engine and let it run until it stops.
3. Leave the engine to cool (approx. 5 minutes).
4. Remove the spark plug (see section 9.4).
5. Add one teaspoon of 2-stroke engine oil into
the combustion chamber. Slowly pull the star-
ter cord several times to apply a layer of oil
to all internal components. Fit the spark plug
again.
Note: Store the equipment in a dry place and
far away from possible ignition sources such as
an oven, a gas-fi red hot water boiler, a gas-fi red
dryer, etc.
Putting the equipment back into operation
1. Remove the spark plug (see section 9.4).
2. Quickly tug on the starter cord to remove ex-
cess oil from the combustion chamber.
3. Clean the spark plug and check that the
electrode gap is correct, or insert a new spark
plug with the correct electrode gap.
4. Prepare the equipment for operation.
5. Fill the tank with the relevant mixture of fuel
and oil. See the section „Fuel and oil".
