Expert inspection required:
• if the trimmer hits an object.
• if the engine suddenly stops.
• if the cutting edge is bent (do not straighten it your-
self!).
• if the transmission is damaged.
Replacing the thread coil/cutting thread
(fig. 35 - 39)
1. Dismantle the thread coil (1) as described in Sec-
tion 8.4. Press the coil together and remove one
half of the housing (fig. 35).
2. Remove the bobbin plate from the thread coil
housing (fig. 36).
3. Remove any remaining cutting thread.
4. Fold the new cut thread in the centre and hook the
resulting loop into the recess in the bobbin plate.
(fig. 37)
5. Wind the thread anti-clockwise under tension. The
bobbin divider separates the two halves of the cut
thread. (fig. 38)
6. Hook the last 15 cm of the two thread ends into the
opposite thread holders of the bobbin plate. (fig. 39)
7. Pass the two thread ends through the metal lugs
in the thread coil housing.
8. Press the bobbin plate into the thread coil hous-
ing. (fig. 36)
9. Pull briefly and firmly on both ends of the thread to
release them from the thread holders.
10. Put the housing halves back together. (fig. 35)
11. Cut back the excess thread to about 13 cm. This
reduces the load on the engine during starting and
warming up.
12. Refit the thread coil (see section 8.4). If the com-
plete thread coil is replaced, skip points 3-6.
Grinding the cutting blade
The cutting blade can become blunt over time.
• If you notice this, loosen the screws securing the
cutting blade to the protective cover.
• Fasten the blade in a bench vice.
• Grind all 3 cutting unit blades using a flat file and
make sure to maintain the angle of the cutting edge.
Only file in one direction.

Replace or sharpen the cutting edge at the end of each
mowing season or as needed.
The brush cutter can vibrate excessively if the cutting
edges are not balanced; therefore there is a danger of
injury!
Replacing and cleaning the spark plug (fig. 32 - 33)
1. Once the engine has cooled down, remove the
spark plug with the supplied socket spanner.
2. Clean the spark plug with a wire brush.
3. Set the gap to 0.5 to 0.7 mm with a feeler gauge.
4. Insert the spark plug carefully by hand so that the
thread is not damaged.
5. After the spark plug is inserted, tighten it with the
spark plug wrench.
Cleaning the air filter (fig. 30 - 31)
Fouled air filters diminish the engine output due to re-
duced air supply to the carburettor. Regular inspection
is therefore essential.
• Loosen the air filter cover and remove the sponge
filter element.
• Replace the air filter cover so that nothing falls into
the air duct.
• Wash the filter element in warm soapy water, rinse
and allow to air dry.
Attention: Never clean the air filter with petrol or
combustible solvents.
m Warning!
Never leave the engine running if the air filter ele-
ment is not inserted.
Lubricating the angular gear
Treat with lithium-based grease. Remove the screw
and put in the grease, turn the shaft manually until the
grease comes out; and then attach the screw again.
Storing the device
Clean the device thoroughly after use. Store the de-
vice in a dry place and allow the engine to cool down
beforehand.
12. Repair & ordering spare parts
After repairs or maintenance, make sure that all safe-
ty-related parts are installed and are in perfect con-
dition. All parts which may cause injury must be kept
where they are inaccessible to children or others.
