Maintenance and treatment of tyres
F_02_122a
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.
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).
