Working Pressure Of Air Brakes; Maintenance And Treatment Of Tyres; Storing The Tractor; Diesel Particle Filter Maintenance - Zetor Proxima GP Series Operator's Manual

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 non-return 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.

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).

Diesel particle filter maintenance

Leave the maintenance of diesel particle filter to an
authorized service.
