If the tyres permanently leak air, check if the tyre casing is damaged – if so, repair.
If you are not sufficiently technically competent, assign this task to a professional service centre.
2.5.1.2 Wheel idle function
Torque is transferred from the wheel axle by a circlip pin. Both wheels, the left or the right, may be disengaged 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.
2.5.2 Lubrication of the machine
When working with lubricants, follow basic hygiene rules and regulations and laws for protecting the
environment.
If you are not sufficiently technically competent, assign this task to a professional service centre.
Adequate care must be taken when lubricating to ensure problem-free and easy movement of all mechanical parts. Usually, several drops
of oil will suffice (e.g. bicycle oil). The gearbox is factory filled with sufficient oil, which does not need to be changed during the life of the
machine.
Check the oil level in the gearbox. If leaking, fill up with recommended oil.
2.5.2.1 Changing the engine oil
Follow the directions specified in the engine operating manual. Reduce the exchange intervals to one half, if you use the machine in a
dusty environment. When draining the engine oil, tilt the machine to the side, where the filler and oil dipstick are or remove the entire
engine from the frame with the engine plate.
If you are not sufficiently technically competent, assign this task to a professional service centre.
2.5.3 Lubrication points
No cover needs to be removed from the machine when lubricating the cables on the handlebars. Other lubrication points are accessible
after remove the plastic covers. From the wide variety of oils, any engine oil, gearbox or transmission oil, or spray oil is appropriate. From
plastic lubricants (grease), any grease made for lubricating water pumps will fully suffice. The corresponding ball bearing must usually be
removed to apply it, however.
When using grease with added graphite, the lubrication intervals during the season may be extended up to
25 hours
.

2.5.4 Sharpening, replacing the work tool
If the work tool blades are worn or damaged, cause the machine to vibration, the blades need to be restored or replaced. Even though
the work tool is made from high quality hardened steel, blade wear occurs leading to less efficient cutting.
The machine must be standing on a solid base and secured such that it affords goods access to the blade and
spontaneous movement of the machine does not occur.
To remove the
blade
(

on
Pic. 6
) from
the blade holder
2
, first loosen and remove the
centre screw
5
. Then loosen
the nut
1
and loosen both
screws
4
and remove. Take out the
blade
3
.
The manufacturer disclaims any liability for damage to property or injury caused by the machine or to the
machine when replacing the work tool with a non-original part. A symbol is imprinted on the blade that
designates the manufacturer and it serves as an inspection symbol that the blade is an original replacement part!
If the screws (
4
or
5
) are damaged, replace them with new ones!

If the tyre pressure is below the minimal level, the tyre casing becomes damaged and the life expectancy of the tyre is thereby significantly reduced.
