MAINTENANCE AND TREATMENT OF TIRES
Regularly inspect the outer surface of a tire and inspect that there are no defects in
side or above the base part of rollers and that body is not damaged.
Remove tires which have defects from further use.
TIRE INFLATION
Basic values of recommended inflation are given in chapter "Main technical parame-
ters”. Check pressure regularly before driving, if tires are cold. Use pressure regula-
tor for inflation (A), which fulfils the function of pressure equalizer, tire filler and lock-
ing valve. Screw a hose for tire inflation. Screw the hose to the end of coil so that
back valve will be compressed. If there is maximum pressure in air collector, a tire
cannot be inflated. In such case it is necessary to first lower the pressure by a valve
for draining condensate placed in the bottom part of air collector (B).
DETACHING TRACTOR
When putting the tractor out of operation
for a longer period of time (warehous-
ing), support the tractor and lower the
pressure in tires to a minimum (wheels
must not touch the ground).
