8. Cleaning, maintenance and ordering
of spare parts
Always switch off the equipment and pull out the
spark boot plug before carrying out any maintenance
work.
8.1 Replacing the line spool/cutting line
1. Dismantle the line spool (13) as described in
section 6.1.6. Press the spool together (Fig. 12a)
and remove one half of the housing (Fig. 12b).
2. Take the line spool out of the line spool housing
(Fig. 12c).
3. Remove any remaining cutting line.
4. Place the new cutting line in the center and attach
the resulting loop to the recess in the spool
splitter (Fig. 12d).
5. Wind the line on to the spool counter-clockwise
with tension. The spool splitter will separate the
two halves of the nylon line (Fig. 12e).
6. Hook the last 15 cm of the two ends of the line to
the line holders opposite the line spool (Fig. 12f).
7. Thread the two ends of the line through the metal
eyelets in the line spool housing (Fig. 12c).
8. Press the line spool into the line spool housing.
9. Pull the two line ends briefly and powerfully to
release them from the line holders in the line
spool.
10. 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.
11. Fit the line spool again. See section 6.1.6. If you
are replacing the complete line spool, ignore
points 3-6.
8.2 Servicing the air filter
Soiled air filters reduce the engine output by supply
too little air to the carburetor. Regular checks are
therefore essential. The air filter (35) 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. 10a).
2. Remove the air filter (Fig. 10b/10c)
3. Clean the air filter by tapping it or blowing it.
4. Assemble in reverse order.
Important: Never clean the air filter with petrol or
inflammable solvents.

8.3 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. Dismantle the protective cap (Fig. 11a/Item 21)
using a screwdriver.
2. Pull off the spark plug boot (Fig. 11b) using the
pull hook (31).
3. Remove the spark plug (Fig. 11b) with the
supplied spark plug wrench (27).
4. Assemble in reverse order.
8.4 Grinding the safety hood blade
The safety hood blade can become blunt over time.
When you notice this, undo the two screws holding
the safety hood blade to the safety hood. Clamp the
blade in a vise. Sharpen the blade with a flat file and
make sure that the angle of the cutting edge is not
altered in the process. File in one direction only.
8.5 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 10a and 10b.
Setting the throttle cable
If the maximum speed of the equipment falls over
time and you have ruled out all the other causes listed
in section 11 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. 13a) is completely
opened when the throttle is fully activated.
Figure 13a shows the correct setting. If the carburetor
slide is not completely open, it must be adjusted.
The following work is 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.
