Working Pressure Of Air Brakes

In the single- and double-hose version the air pressure at the double-hose coupling (2) (red cap) is 740 ± 20 kPa and at the single-hose coupling (1) max. 600 ± 20 kPa (at the moment the pressure controller relieves the compressor - blows out the air).

Maintenance And Treatment Of Tyres

Regularly check the outer surface of tyres and verify whether they are free of defects at the sides and over the bead and whether the reinforcement is not damaged.

Do not use tyres that show a defect any longer.

Tyre Inflation

The basic recommended inflation values are specified in the table. Regularly check the tyre pressure before driving, when the tyres are cold. To inflate the tyres use the pressure controller (B), which acts as a pressure equalizer, tyre filling device and safety valve. Remove the rubber cap of the pressure controller and screw a tyre inflation hose instead. Screw the hose up to the end of the thread to compress the nonreturn valve. If there is the maximum pressure in the air reservoir (A), the tyres cannot be inflated. In this case you must first reduce the pressure with the condensate drain valve located in the bottom part of the air reservoir (A). After inflating the tyres you must put the rubber cap back on the pressure controller.

Recommended Inflation Values Of The Front Wheel Tyres

The value of the permitted load-bearing capacity of the front axle must not exceed the sum of the load-bearing capacity values of both the tyres that are installed on the axle. The values of the permitted load-bearing capacity of the axles are specified in the “Main technical parameters” of the corresponding tractor type. On the same axle of the tractor there must not be tyres of different dimensions and designs (in this case tyre design means the diagonal or radial tyre version).

For work with a front loader at the maximum permitted speed of

Note: The 380/70R24 tyre is a dimensional equivalent of the 13.6R24 tyre. The 420/70R24 tyre is a dimensional equivalent of the 14.9R24 tyre. The specified load-bearing capacities of tyres for field work and road transport correspond to the maximum travelling speed of the tractor, i.e. in the case of radial tyres 40 km/h and in the case of diagonal tyres 30 km/h. The specified values refer to one tyre. For a tractor the max. load per axle must not exceed the max. load-bearing capacity values of the tyres.

Recommended Inflation Values Of The Rear Wheel Tyres

The value of the permitted load-bearing capacity of the rear axle must not exceed the sum of the load-bearing capacity values of both the tyres that are installed on the axle. The values of the permitted load-bearing capacity of the axles are specified in the “Main technical parameters” of the corresponding tractor type. On the same axle of the tractor there must not be tyres of different dimensions and designs (in this case tyre design means the diagonal or radial tyre version).

Note: The 480/70R38 tyre is a dimensional equivalent of the 16.9R38 tyre. The 570/70R38 tyre is a dimensional equivalent of the 18.4R38 tyre. Inflate the front as well as the rear tyres to the lower of the above mentioned values for field work on light soil (dry, sandy). The higher of the above mentioned pressure values is designed for work on heavy and compact soil. During ploughing work at the minimum inflation value there must not be any folding of the side parts of the tyres. The load-bearing capacities specified in the tables correspond to the maximum travelling speed of the tractor, i.e. in the case of radial tyres 40 km/h and in the case of diagonal tyres 30 km/h. The specified values refer to one tyre. For a tractor the max. load per axle must not exceed the max. load-bearing capacity values of the tyres.

Maintenance Instructions

During loading of the tractor the maximum values of the permitted load-bearing capacity of the axles mentioned in the “Technical parameters of the tractor” table must not be exceeded. Changes of the load-bearing capacity of the tyres from the basic values are specified in the tables below. Note: The 100% inflation values of tyres are specified in the tables of recommended tyre inflation in the part "Principal working activity - for field work”.

Storing The Tractor

If the tractor is to be put out of operation for a shorter period, inflate the tyres to the value required for road transport. In case of a longer period of inactivity of the tractor (storage), support the tractor and reduce the pressure in the tyres to the minimum (the wheels must not touch the ground).

** minimum value for 6 PR

It is not allowed to increase the loadbearing capacity of the tyres except the above mentioned cases by further increasing the inflation pressure above the values mentioned in the table while simultaneous decreasing the speed.

Most of the following tasks require certain experience and advanced maintenance and diagnostic equipment. Therefore, we recommend you to entrust this work to specialized or authorized workshops.
