HEATING SYSTEM AIR FILTER
CLEANING
Filters are located under grills above the
front windshield outside the cab.
Regenerate filters by kicking out, or by
pressure air blowing through, according
to the stage of clogging. Daily check for
clogging. Exchange the strong clogged
filters.
Tractors are not equipped with
special filters of cab intake air.
That’s why tractors are not in-
tended for operation with aero-
sols and other health dangerous
mediums.
DRAINING OF CONDENSED WATER
FROM AIR TANK
Drain the condensed water by inclination
of draining valve by pulling of its ring.
Valve is located on the bottom part of air
tank.
AIR SYSTEM INSPECTION FOR
LEAKS
- Fill the air tank to the max. pressure.
- The pressure must not drop down by
more than 10 kPa after 10 minutes at
stopped engine.
Daily inspect the system for leaks
before operation with trailer. The
indicator light on the dashboard
is “on“ when the air brake system
fails or after dropping of pressure
under 420 kPa.
