2.4.4 Selecting the wheel drive speed

Certain versions of the machine are available in two-speed design
for removing dirt, a faster speed (with the belt fitted as shown in Fig. 6 ) is suitable for removing snow or leaves.
Speeds are changed by moving the V-belt on the pulleys between the gearbox and the drive axle (see Fig. 5 And Fig. 6 ). A sticker is
glued on the top gearbox cover with a picture of the belt positions in the pulleys on the gear box and the drive axle (see Fig. 8 ).

The engine must always be off and the gas lever in the
Procedure:
1) Loosen the plastic nut (
diagonally backwards. Push in the foot
frame until the cover releases and pops out of the frame tab
frame.
2) Slide the whole V-belt of the pulley on the axle towards the left wheel. Subsequently then slide the V-belt from the pulley on the
gearbox towards the right wheel.
3) Move the V-belt into the pulley groove on the axle that corresponds to the selected transfer ratio. Check visually and by touch if
the V-belt sits properly in the groove on the selected pulley.
4) Move the V-belt into the pulley groove on the axle that corresponds to the selected transfer ratio. Check visually if the V-belt sits
in the correct pulleys according to the selected transfer ratio (see Fig. 5 and Fig. 6 ). The V-belt must not cross!
5) Reinstall both of the covers. Place the upper plastic cover under the engine plate, close it, and tighten the plastic nut. Bend the
bottom plastic cover upwards. Place it into the gaps at the foots on the frame sides (see detail on Fig. 7 ). Place the opening into
the foot 4 of the cover on the frame tab. Loosen the deflection of the cover, and the cover will sink into place.

2.4.5 Wheel idle function

Torque is transferred from the wheel axle by a circlip pin –
from the transfer of force on flat terrain by removing the circlip pin from one of the wheels. Only one wheel then drives and it then makes it
easier to turn around at the end of the row.

Keep in mind that the machine with such a setup shall turn (pull) towards the side, where the pin was removed.

2.4.6 Adjustment of the working implement

2.4.6.1 Pressure adjustment of the cylinder sweeping brushes

The correct pressure of the bristles should always be set on a flat surface. Initially, set the smallest possible distance between the end of
the bristles and the spacer. While doing so the bristles may be slightly compressed. Then remove the spacer to set the correct pressure.
Removal and insertion of the supporting wheel according to Fig. 2 - 5) and point 5) of chapter 2.4.1.1.
Recommended pressure:
a) for dirt - the pressure is achieved by removing one or two spacers
b) for snow - the pressure is achieved by removing two to three spacers

Note that when you switch off the travel mode while the drive is still engaged the machine reacts with quite a
strong reverse movement especially when the pressure on the bristles is higher. Accordingly, pay attention to
personal safety, especially in places where the space behind the back of the operator is limited.

2.4.6.2 Rotation of cylinder sweeping brushes


When changing the speed of rotation of the cylinder sweeping brushes make sure that the drive and drive of the
cylinder sweeping brushes are always switched off!
Fig. 9 To set the turning angle of the cylinder sweeping brushes axis it is necessary to slightly lift the turning lever
pipe 2 is released from the locking groove
sweeping brushes 5 to the desired angle. Release the lever so that it can slot into a required locking groove.

When changing the angle of the cylinder sweeping brushes slightly release the weight of the front of the machine by
pressing the top on the handle grips.

2.4.7 Working with the machine

2.4.7.1 Sweeping of dirt

1. For better clean up of an area select a slower speed
2. Proceed on a cleaned surface always in strips. In case of dirt accumulating in large quantities, and:
a) the cylinder sweeping brushes start tossing the dirt into space behind the cylinder sweeping brushes, or
b) they start leaving a track in the space below the gearbox
The single speed version can be changed to a two-speed machine with the use of a conversion set. Separate accessories are available as optional extra and are not part of the basic
62
equipment of the machine! The conversion can be done only by authorized services!
Loosen the plastic nut by about 1 to 2 turns. The cover contains a groove that enables removal of the cover without the need of unscrewing the plastic nut.
