MAINTENANCE OF THE AIR
CONDITIONING DEVICE
The most important item of main-
tenance of the air conditioning
system is the cleaning of the air
conditioning condenser (installed
ahead of the engine radiator).
The clogged air conditioning con-
denser not only impairs the cool-
ing efficiency of the air condition-
ing system, but also the cooling
efficiency of the engine.
Remove the front side panel of the bon-
net, release and slide the radiator to a
side. Then clean it with compressed air
or rinse it with pressure water (against
the direction of the tractor drive)-.
Then slide the radiator back and fix it
properly. Beware of the oil radiator
hoses.
If the operation of the air conditioning is
correct, condensation of water in the cab
roof compartment takes place. The con-
densate is evacuated with hoses in the
cab posts and is discharged in the bot-
tom part of the posts. Therefore attention
should be paid to those hoses and free
condensate evacuation.
DISCHARGING THE CONDENSATE
FROM THE AIR STORAGE TANK
Do it with deviating or depressing the
valve protruding part.
The air storage tanks are located ahead
of the rear axle.
In the Z 8641 - Z 11441 tractor one air
storage tanks is normally mounted at the
L.H. side of the tractor or * two air stor-
age tanks are fitted at the R.H. and L.H.
sides of the tractor (in case the pneu-
matic brakes are mounted).
At tractor Z 11741 both air tanks
are assembled as a standard.
