7.2.3 Maintenance of the gearbox (Fig. 15)
The gearbox must be lubricated every year before
the start of the season at the lubrication nipple
(Fig. 15/Item A). Place a conventional grease gun
on the nipple and press approx. 3 strokes of con-
ventional machine grease into the gearbox. If you
use the trimmer frequently, grease the gearbox
more often.
7.2.4 Carburetor settings
Important. Settings on the carburetor may only be
made by authorized customer service personnel.
Setting the idling speed:
Important. Set the idling speed when the machine
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 9 Troubleshooting, the idling
speed must be adjusted. To do this turn the idling
speed screw (Fig. 16/Item 5) clockwise until the
machine runs smoothly at idling speed.
If the idling speed is so fast that the cutting blades
do not reach a standstill, the idling speed must
be reduced by turning the idling speed screw
(Fig. 16/Item 5) counterclockwise until the cutting
blades stop.
7.3 Storage
Please note: If you fail to follow these instructions
correctly, deposits may form on the interior of the
carburetor which may result in the engine being
more diffi cult to start or the machine suff ering per-
manent damage.
1. Carry out all the maintenance work.
2. Drain the fuel out of the tank (use a conventi-
onal plastic petrol pump from a DIY store for
this purpose).
3. When the fuel has been drained, start the en-
gine.
4. Allow the engine to run at idling speed until it
stops. This will clean the remainder of the fuel
out of the carburetor.
5. Leave the machine to cool (approx. 5 minu-
tes).
6. Remove the spark plug (see point 7.2.2).
7. Place a teaspoon full of 2-stroke engine oil
into the combustion chamber. Pull the starter
cable several times carefully to wet the inter-
nal components with the oil. Fit the spark plug
again.
8. Clean the exterior housing of the machine.

9. Store the machine in a cold, dry place where
it is out of the reach of ignition sources and
infl ammable substances.
10. Always place the cover over the cutter when
transporting or storing the equipment.
Fertilizers and other chemical garden products
often contain substances that accelerate the rate
of corrosion of metals. Do not store the machine
on or near fertilizers or other chemicals.
Restarting
1. Remove the spark plug.
2. Pull the starter cable several times to clean
the oil residue out of the combustion cham-
ber.
3. Clean the spark plug contacts or fi t a new
spark plug.
4. Fill the tank. See the section entitled Fuel and
oil.
5. Complete steps 1-7 described under the
point entitled "Starting the engine from cold".
