Air Conditioning System - Case WX145 Operator's Manual

TRAVEL GEARBOXES - OIL LEVEL
Bring the screw plugs (1) and (2) into position
depending on the wheel-hub installed. The line
under the word "REAR" or "OIL" must be in horizon-
tal position.
Clean the area around screw plugs (1) and (2).
Unscrew the screw plug (1) slowly, until the inner
pressure is completely released. Only after this
operation, unscrew the plug completely. The oil level
must be flush with the hole edge. If necessary, top
up oil through the hole.
Screw up the screw plug (1).
Repeat this check on the wheel-hub at the opposite
axle end.
Lower the machine.

AIR CONDITIONING SYSTEM

If the system is not used at least once a month (for
instance during winter), it is necessary to perform a
visual check of the system status and of its main
components.
Moreover, it is necessary to let it run for at least 10-15
minutes.
In this way you avoid that the oil seal on the com-
pressor shaft dries and becomes fragile. In this case
coolant leaks may take place. Besides, in this way
all compressor components are periodically lubri-
cated.
