3.5.1 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.
3.5.1.1 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!
➢ MAXimum (
recommended
) tyre pressure: 21 PSI (144,7 kPa or 1,44 bar or 1,42 atm or 0,144 Mpa)
➢ MINimum
85
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.
3.5.2 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.
3.5.2.1 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.
3.5.2.2 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.

3.5.3 Work blades service and exchange
Seek authorised service in case you lack appropriate manual skills.
If the work blades are deteriorated or damaged and causing cutter vibrations, it is necessary to renew or exchange the blades
86
.
Note:
he manufacturer bears no responsibility for damages caused by/on the cutter in case of a botched-up blades repair or when
original parts are not used. A sign identifying the manufacturer is imprinted in the blade and it is used as a proof of a genuine part.
The cutter must be secured from unexpected spontaneous movement and stand on a safe pad to allow adequate access to the
blade.
Pay special attention when dismounting the blades. The cutting blades are sharp. Protect your hands with work gloves.
The engine must be off and the end of the spark plug cable must be taken off!
Proceedings:
1) Hold the upper disc so that it does not spin and use tubular wrench n.16 to dismount the bolted connection of the blade. First
unscrew the nut, than the bolt.
85
Tyre pressure lower than minimum damages the tyre construction and shortens its life.
86
The blades are double-sided; they can be turned around if necessary. The blades must never be damaged.
