Air-conditioning maintenance
The most important element of the maintenance
of the air-conditioning system is cleaning of the
cooler (condenser) of the air conditioning (it is located
in front of the engine cooler). The full condenser of
the air conditioning decreases not only the efficiency
of the cooling of the air-conditioning system, but also
the efficiency of the engine cooling.
Lift up the engine bonnet, disassemble the locking screw
(1) and release and push out the cooler in the direction of
the arrow.
Blow out with compressed air or rinse out with pressure
water (against the tractor travelling direction).
Then insert the cooler back and mount the locking screw
(1).
Make sure that the hoses correctly guided.
When the air-conditioning functions properly, water condenses in the roof space of the cab and the
condensate is drained through hoses in the cab pillars and runs out at the bottom side of the pillar. This is
why you must make sure that the condensate drain hoses will not be blocked.
Checking the air systems for leaks
- Fill the air tank to the maximum pressure
- with the engine stopped, the pressure drop of more than
0.15 bar must not occur in 10 minutes.
Check leakage daily before driving with a trailer
or semi-trailer. If the brake system fails or the
pressure drops below 10 bar, the warning light on the
dashboard lights up.
