Adjustment of the neutral position of the pump
lever – Fig. 15d
The neutral position of the pump lever is adjusted by the
change of the length of the draw bar by turning ball pin "K”.
After the adjustment, it is necessary to secure the pin in the
correct position with the counter-nut.

Replacement of lamps
Lamps are located in the sleeve with bayonet fastening which
can be removed by turning.
Replacement of the fuse
The electronics and the electrical installation are protected by a
10A fuse. For locating and removing the failure it is necessary
to replace the damaged fuse with a new fuse with the same
current value. For the heating of the bag and the lifting of the
front hinge, there is s 10A fuse. The fuses are located in the
pocket located under the panel on the side of the accumulator
cover. Never use fuses with another value of the current. If
after the replacement of the fuse, the self-moving cutter does
not function, it is necessary to contact an authorized service.
Replacement of wheels
Disconnect the self-moving rotary cutter under the load-
bearing part of the chassis on the part of replacement of the
wheel. The front and rear wheels are secured by the pad and
the pin. During assembly it is necessary to open the pin for the
correct placement of the cover of the axis end. The rear wheels
are mounted directly on the semi-axes of the differential
equipped with a plain key. When attaching the wheels it is
necessary to lubricate the axes with grease. In the case of the
replacement of one or both rear wheels it is necessary to take
care to keep the same diameter of the wheels or to check the
adjustment of the cutting mechanism.
Repair of tyres
The self-moving rotary cutter is equipped with tubeless tyres.
The repair of these tyres must be performed by a professional
service.
Removing of the transport channel
Before the removing of the transport channel it is necessary to
disconnect the electric conductors on the sensor for the filling
of the bag. The disconnecting connector is located near the
sensor in the front upper part of the transport channel. By
lifting the front part of the channel, the leading locks are
released and it is possible to shift the transport channel in a
backward direction. Re-assembly is performed by following
the opposite procedure. (Note: To draw out the channel, the
cutting mechanism must be slightly lifted).
Sensor for filling the bag
In the front upper part of the transport channel, it is necessary
to clean the free capacity of the sensor membrane from the
remainders of grass (Fig.15e) – the best is after each cutting!
Fig.15e
Notification!
The function for the automatic checking of the filling of the
bag depends on the composition of the cut grass! For
example, in the case of cutting dense wet spring grass it is
possible to disconnect the drive of the cutting equipment in
the case that half the bag is filled. On the other hand, when
cutting autumn dry grass the grass bag can be filled to the
maximum possible volume.
Dismantling of the cutting mechanism
When dismantling the cutting mechanism it is necessary to:
1. remove the transport channel
2. readjust the cutting mechanism to the lower position
3. disconnect the belt of the drive of the cutting
mechanism
4. lift the cutting mechanism into the position “2-3”
5. disconnect the front hinge pins
6. insert into the hubs of the rear hinges the auxiliary bar
with the diameter of 12 – 15 mm, length 300 mm, by
means of which it is possible to lighten the draw of
the hinge arm. Draw out the pin to disconnect the
