2.8.1 Machine lubrication

Observe basic hygiene rules, regulations and legislative acts on environmental protection when working with
lubricants.

If you are not sufficiently skilled manually, entrust this work to professional service.
2.8.1.1 Gearbox oil change
Gearbox is filled with gear oil intended for highly loaded gears, specifications SAE 80W-90 .
Change the oil when it is warm, it drains better from the gearbox. The drain plug is at the bottom of the gearbox ( 1
on Pict. 22), the oil
fill plug on the right side of the gearbox when viewed from the operator’s position( 2 on Pict. 22).

The fill hole can be used for checking. The gearbox oil level must reach to the lower edge of the screw thread.
1. Remove the oil drain plug (spanner No. 17).
2. Tilt the casing and pour the oil into a container.
3. Lay the gearbox on its left side. Screw in the drain plug, unscrew the fill plug. Fill the gearbox with the new oil, the filling volume
is
1,5 litres . For easy filling we recommend using syringe type JANETTE with a volume of 150 ml.
4. Replace the seal under the plug, screw it back and tighten it.
2.8.1.2 Lubrication points
Pay adequate attention to lubrication to ensure a trouble-free and easy movement of all mechanical parts. From a wide range of oils any
oil in spray or oil for bicycles is suitable. Out of plastic lubricants (grease) any lubricant intended for water pumps is fully sufficient.
However, for its application it is usually necessary to dismantle the appropriate slide assembly.

Do not use plastic lubricant containing graphite on the freewheel hubs. The graphite contained in the lubricant
gradually jams the locking finger grooves and the freewheel hub will not work reliably. There is the danger of
accident and injury if the finger does not fall into the groove in the hub. A freely rotating wheel can suddenly pull
the small one-axle tractor to side!

IMPORTANT NOTICE: Never lubricate the hexagonal driving surfaces on the output shaft of the gearbox, or the
internal hexagonal surfaces in the semi-axes or in the star-shaped tillers! Oil together with dirt creates a layer of
a very durable matter (similar to cement), which prevents easy removal of the drive axle or tiller implement
spacers!

Exchange after first 10 hours (running-in of the
gearbox), then after 100 hours of operation or
after the season.

The plastic lubricant can be applied only when
the wheel hub is disassembled.

2.8.2 Tyre pressure
For proper operation and to ensure long life of the travel wheels, especially the tyres, it is necessary to check the tyre pressure. Check
the pressure before starting work with the machine. Keep equal pressure 57 in both the left and the right wheel - the machine keeps a
straight track better.
Before prolonged shutdown of the machine inflate the tyre to MAX (see below).

Do not exceed the maximum tyre pressure - there is a risk of the tyre exploding!

If the tyre pressure is low, there is a danger of shearing off the tyre tube valve.

MAX imum (recommended) tyre pressure: 23 PSI ( 160 kPa or 1,6 bar or 1,57 atm or 0,16 Mpa )

MIN imum 58 permissible tyre pressure: 18 PSI ( 124,1 kPa or 1,24 bar or 1,22 atm or 0,124 Mpa )
In case of a continuous air leak in the tyre, check if the tyre tube is not defective and repair if necessary.

If you are not sufficiently skilled manually, entrust this work to professional service.
57
The pressure is given by the tyre casing manufacturer and indicated on the side of the casing. Do not exceed the maximum pressure value.
58
If the tire pressure is less than the minimum, the tyre construction damage occurs thereby significantly reducing its lifetime.
