2. Then trap the end of each thread in one
of the grooves (61) on the spool (53).
Pull the threads tight and ensure that
they are parallel in the two thread
channels. In addition, the thread spool must
not be lled with more than 3 m of thread
in each channel, as otherwise the automatic
thread mechanism will not function correctly.
Lubricating the gears
The gears require lubrication after around
10 hours of operation.
Fig.

1. Loosen the screw (62) on the gears us-
ing the large 5 mm Allen key (32).
2. Insert around 5 g of commercially-avail-
able lubricating grease into the lubrica-
tion opening on the gearbox housing.
3. Close the gears again using the screw
(62).
Adjusting the Carburettor
The carburettor is preset in the factory for
optimal performance. If subsequent adjust-
ments are required, have them carried out
by a specialist workshop.
Removing blockages
Switch the device off and
remove the spark plug
connector (

on the cutting unit.
Wear protective gloves in order to
avoid cutting yourself.
Maintenance Intervals
Regularly carry out the maintenance work
listed in the “maintenance intervals” table.
