Working pressure of air brakes
Maintenance and treatment of tyres
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).
PGPPN153
Check the outer surface of tires regularly to ensure that
the tires do not have defects in the side part or the part
above beads and they do not have damaged carcases.
Discard defective tires from further use.
Tire inflation
The basic values of the recommended inflation pressure
are listed in the table. Check tire pressure regularly before
driving, when the tires are cold. For inflation, use
a pressure regulator, which functions as a pressure
equalizer, tire filler and safety valve, located on the left
side of the engine. Remove the pressure regulator rubber
cap and screw the tire inflation hose in that place. Screw
the hose to the end of the thread so that the return valve is
compressed. The tire cannot be inflated if there is
maximum pressure in the air reservoir. In this case, it is
necessary to reduce the pressure using the condensate
drain valve located at the bottom of the reservoir. When
the tires are inflated, the rubber cap must be placed back
on the pressure regulator.
