Maintenance And Care For Tyres; Inflation Of Tyres; Laying By The Tractor - Zetor Proxima Series Operator's Manual

MAINTENANCE AND CARE FOR TYRES

Check regularly outer surfaces of the tyres and their sides for defects in side walls
and at tyre beeds and damaged tyre skeletons.
Take out of service tyres with any defects.

INFLATION OF TYRES

Basic values of recommended inflation are specified in the chapter "Essential techni-
cal parameters". Check pressure regularly before you drive out if the tyres are cold.
Use the pressure regulator (B) for inflation; this device is used for balancing of pres-
sure, inflation of tyres and as a safety valve. Screw off the wing nut on the pressure
regulator (or remove the rubber cap) and screw in a hose for inflation of tyres instead.
Screw in the hose up to the end of its thread to squeeze the backflow valve. In case
that there is maximum pressure 0.6MPa (or 0.7MPa with double-hose brakes) in the
air accumulator, tyres cannot be inflated. In such case it is necessary first to reduce
pressure using the valve for draining of condensate that is installed on the air accu-
mulator bottom (A). After inflation of tyres it is then necessary to screw on the wing
nut onto the pressure regulator (or put back the rubber cap).

LAYING BY THE TRACTOR

In case that the tractor has to be put out
of operation for a longer period (storage),
support the tractor and reduce pressure
in tyres for minimum (the wheels may not
be in contact with ground).
