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".

It is not allowed to increase the load-
bearing capacity of the tyres except the
above mentioned cases by further in-
creasing the inflation pressure above the
values mentioned in the table while si-
multaneous decreasing the speed.

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).
