machine. Do not use caustic cleaning products.
7.2.1 Maintenance of the air filter (Fig. 9-11)
Soiled air filters reduce the engine output by supply
too little air to the carburetor.
Regular checks are therefore essential. The air filter
should be checked after every 25 hours of use and
cleaned if necessary. If the air contains a lot of dust,
the air filter should be checked more frequently.
1. Remove the air filter cover (Fig. 9-10)
2. Remove the filter element (Fig. 11)
3. Clean the filter element by tapping it or blowing
it.
4. Assemble in reverse order.
Please note: Never clean the air filter with petrol or
inflammable solvents. Clean the air filter with
compressed air or by tapping it.
7.2.2 Maintenance of the spark plug (Fig. 12-14)
Spark plug gap = 0.025 inch (0.635 mm). Tighten the
spark plug with a torque of 12-15 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 off the spark plug boot (Fig. 13) by twisting.
2. Remove the spark plug (Fig. 14) with the
supplied spark plug wrench.
3. Assemble in reverse order.
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 conventional
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.
The air filter cover must be removed before any work
on the carburetor, as shown in Figures 9 – 10.
Setting the throttle cable:
If the maximum speed of the machine falls over time
and you have ruled our all the other causes listed in
section 9 Troubleshooting, it may be necessary 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 (Fig. 16/Item 1) rests
against the stop (Fig. 16/Item 2) when the throttle is
fully open. Figure 16 shows the correct setting. If the
10
carburetor slide does not touch the stop, it must be
adjusted.
The following work is required to adjust the throttle
cable:
Undo the lock nut (Fig. 17/Item 3) a few turns.
n
Undo the adjusting screw (Fig. 18/Item 4) until
n
the carburetor slide rests against the stop when
the throttle is fully open, as shown in Figure 16.
Retighten the lock nut.
n
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 causes listed in
section 9 Troubleshooting, the idling speed must be
adjusted. To do this turn the idling speed screw (Fig.
19/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.
19/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
difficult to start or the machine suffering permanent
damage.
1. Carry out all the maintenance work.
2. Drain the fuel out of the tank (use a conventional
plastic petrol pump from a DIY store for this
purpose).
3. When the fuel has been drained, start the
engine.
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 minutes).
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 internal
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
inflammable substances.
10. Always place the cover over the cutter when
transporting or storing the equipment.
