desired position. Be aware of the higher danger of injuries
for the operator, surrounding persons and animals, and
the danger of damages to property through hurled-away
objects (e.g., stones) (Fig. 16).
Extending the cutting cord
To extend the cutting cord let the engine run at full throttle
and bump the cutting head on the ground. The cord is
automatically extended. The cutter at the protection cover
cuts the cord to the required length (Fig. 17).
Important note: Do not use metal wire or plastic-
sheathed metal wire of any kind in the cutting
head. This may lead to serious injuries of the
operator.
ATTENTION: Regularly remove any remainders
of grass and weed to avoid an overheating of
the shaft tube. Remainders of grass and weeds
get caught under the protection cover (Fig. 18)
avoiding a sufficient cooling of the shaft tube.
Remove the remainders carefully with a screw-
driver or a similar tool.
Replacing the cutting cord
1. Remove the screw by turning it anticlockwise (Fig. 19).
2. Remove the coil and spring from the spindle (Fig. 20).
3. Remove the remaining cutting cord (Fig. 21).
4. Fold a 6m x 2mm cord in half. Put the loop end into
the slot of the spool (Fig. 22). The slot is located in the
centre wall that divides the two cord chambers from
each other.
5. Roll both halves of the cord concurrently around
the spool. The wrapping direction is engraved in the
spool: “Wind Cord”. Make sure that the cord is always
tensioned and that each half of the cord stays in the
proper separate spool housing. Roll up the cord until
15 cm of cord remain at each end.
6. Lead each cord end through the openings at the re-
spectively opposite side of the coil (Fig. 23).
7. Lead the spring over the spindle and thread the cord
ends through the eyelets in the housing.
8. Lead the coil into the housing while pulling the cord
ends through the eyelets. Make sure that the spring is
positioned correctly in relation to the coil and housing
(Fig. 24).
9. When the coil sits in its correct position in the hous-
ing, push it firmly into the housing so that the spring is
tensioned. Firmly pull at both ends of the cord (H) so
that the cord cannot be pinched between the coil and
housing. Maintain the spring tension through continu-
ous pressure on the coil in the housing and fix the screw
by turning it clockwise. Fasten the screw fingertight only
(Fig. 25).
11. Cut the cord to about 17cm to avoid excessive load
to the engine during the starting and warm-up phase
(Fig. 7).
MAINTENANCE AND REPAIR
ATTENTION ! Always wear protective gloves
when carrying out maintenance work. Never
perform maintenance works with the engine
still being hot.
AIR FILTER
To clean the air filter:
1. Remove the fixing screw 1 of the air filter cover (Fig.
26a+b).
2. Clean the filter using soap and water.
Never use petrol or benzene !
3. Let the Filter dry in the air.
4. Now put the filter in again proceeding the other way
round.
NOTE : Replace the filter if it is worn out, damaged or
too dirty.
TANK CAP / FUEL FILTER
ATTENTION : Please remove the fuel from the de-
vice and store it in an approved fuel can, before you
start replacing these parts. Open the tank cap care-
fully to allow existing pressure to slowly decrease.
NOTE: Keep the ventilating valve and tank cap clean
(Fig. 27).
1. Pull the fuel suction head (A) out of the tank using a
hook or similar tool (Fig. 28).
2. Pull the suction head off by concurrently turning it (Fig.
28).
3. Replace the filter.
NOTE : Never use the trimmer without a fuel filter. This
may result in severe damage to the engine.
CARBURETTOR SETTINGS
The carburettor has an optimised setting ‘ex works’. If
any further adjustments should be required contact your
competent customer service.
SPARK PLUG
1. Spark plug air gap: 0,6-0,7 mm (Fig. 29)
2. Tighten the spark plug with a torque of 12-15Nm. Put
the spark plug connector on the spark plug.
ATTENTION: Any maintenance works that are
not explicitly described in these Operating
Instructions must be carried out by an author-
ized workshop. To ensure a consistent and proper
operation use ORIGINAL SPARE PARTS only.
SHARPENING THE CORD CUTTER
1. Remove the cutter (E) from the protection cover (F)
(Fig. 30).
2. Put the cutter into a vice and fix it firmly. Sharpen the
cutter using a flat file. File with care and keep the
sharpening angle. Always file in one direction only.
TRANSPORT
• When transporting the tool by car, it must be positioned
so that it poses no danger, and secured.
• Make sure that no petrol escapes during transport. Avoid
damage and injuries.
STORAGE
1. Follow all aforementioned maintenance instructions.
2. Thoroughly clean the trimmer and grease the metal
parts.
