(Fig. 12f).
7. Thread the two ends of the line through the
metal eyelets in the line spool housing (Fig.
12b).
8. Press the line spool into the line spool
housing (Fig 12a).
9. Cut the excess line to a length of around 13
cm. This will reduce the load on the engine
when starting up and warming up.
10. Fit the line spool again. See section 5.1.6. If
you are replacing the complete line spool,
ignore points 3-6.
9.2 Grinding the safety hood blade
The safety hood blade can become blunt over
time. When you notice this, undo the screw hol-
ding the safety hood blade on the safety hood.
Clamp the blade in a vise. Sharpen the blade with
a fl at fi le and make sure that the angle of the cut-
ting edge is not altered in the process. File in one
direction only.
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
infl 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 out the spark plug connector (20) (Fig. 11a).
2. Remove the spark plug (Abb. 11b) with the
supplied spark plug wrench (26).
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-
10c.

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. 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.
9.6 Setting the idling speed
Note! Set the idling speed when the equipment
is warm.
The idling speed may only be adjusted by an au-
thorized service center. The starting speed of the
cutting tool must be at least 1.25 times the idling
speed.
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 (C)
(Fig. 7c).
9.8 Changing the oil and checking the oil le-
vel (before using the equipment)
The motor oil is best changed when the motor is
at working temperature. In this connection, please
also read the service information.
•
Keep a suitable, leak-tight receptacle within
reach when performing an oil change.
•
Open the oil filler plug (Fig. 14a-14b / Item
10).
•
Drain the used oil into a suitable receptacle
by tilting the engine.
•
Fill in engine oil up to the top mark (Max.) on
the oil dip stick (Fig. 14b).
•
Dispose of the used oil properly by taking it to
a collection point. Most filling stations, repair
garages, and recycling centers will accept
used oil free of charge. Do not add antifreeze
or transmission fluid to the used oil. Keep
used oil out of the reach of children and away
from sources of ignition.
