Stop the cutter and turn the engine off. Dismount the side screen and put it in a safe place, out of the cut area, so that it
cannot be stolen.
2.5 Maintenance, servicing and storage

The weight of the cutter requires two persons for carrying out its maintenance and adjustment.
In order to be happy with our product in the long-term, it is necessary to give it adequate maintenance and servicing care. Regular
maintenance reduces deterioration and ensures proper functioning.
Follow all instructions concerning maintenance and adjustment schedule. It is recommended that you keep a record of the amount of its
working time and conditions (for service needs). It is recommended to let one of our authorised service centres take care of the after-
season maintenance, as well as regular maintenance if you are not sure about your technical skills.

Check the nuts tightening the upper disc blades and nuts tightening the lower disc to the flange before each
cutter use.
2.5.1 Travelling wheels
Travelling wheels create an important part of the cutter. Wheels carry the whole weight of the cutter, transfer engine power, and push
the cutter into mesh.
2.5.1.1 Tyre pressure
Tyre pressure has to be controlled in order to secure proper functioning and long life of the wheels, especially the tyres. Check the
pressure before you start using the cutter. Fill the pressure to MAX before putting the cutter out of service for a longer period of time. Keep
equal pressure in right and left wheels - it helps the cutter to keep a straight track.

Do not exceed the maximum tyre pressure – you risk a tyre explosion!
➢
MAX imum (
recommended) tyre pressure:
23 PSI ( 160 kPa or 1,6 bar or 1,57 atm or 0,16 Mpa )
➢
MIN imum
52
allowed tyre pressure: 18 PSI (124,1 kPa or 1,24 bar or 1,22 atm or 0,124 MPa)
In case of permanent tyre pressure release, check and repair possible tyre defect.

Seek authorised service in case you lack appropriate manual skills.
2.5.2 Machine lubrication

Follow basic hygienic rules and environmental laws when working with lubricants.

Seek authorised service in case you lack appropriate manual skills.
Smooth and easy movement of all mechanical parts requires adequate lubrication. Several drops of oil are usually sufficient (e.g. Bicycle
oil). The gearbox is filled with sufficient amount of oil during manufacturing and it does not require filling during the whole machine life.
2.5.2.1 Engine oil exchange
Follow the engine user manual instructions. If you use the cutter in a dusty environment, shorten the exchange period by half. When
pouring the oil out of the engine tilt the cutter on its filler and oil dipstick side or dismantle the whole engine.

Seek authorised service in case you lack appropriate manual skills.
2.5.2.2 Lubricating points
There is no need to dismount any covers from the machine when lubricating the cables on the handlebars. You can reach other
lubricating points after dismounting the plastic covers. You can use any kind of engine, transmission or spray oil. Any kind of lubricant
grease for water pumps is fully sufficient. For its application, however, it is usually necessary to dismantle the appropriate sliding sealing.
Note: When using graphite grease, the seasonal lubrication intervals can be extended up to 25 hours .
