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. 11a/Item

36).

3. Remove the spark plug (Fig. 11b) 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.
