Maintenance Of The Oil Cooler Of The Front Pto; Maintenance And Treatment Of Tires; Detaching Tractor - Zetor MAJOR HS Series Operator's Manual

Maintenance of the oil cooler of the front PTO

The full oil cooler decreases not only the efficiency of cooling of the front PTO, but also the
efficiency of the engine cooling.
Open the engine bonnet, disassemble the nut (1) from the
right side of the tractor, tilt the cooler to the side, blow out
with compressed air or rinse out with pressure water
(against the tractor driving direction).
Then insert the cooler back and fix properly with the nut.
Make sure that the hoses to the oil cooler are correctly
guided.

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 parameters´. Check pressure
regularly before driving, if tires are cold. Use pressure
regulator for inflation (A), which fulfils the function of
pressure equalizer, tire filler and locking 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 (warehousing), support the tractor and
lower the pressure in tires to a minimum (wheels must not
touch the ground).
