1. Technical data
Water cooling
See
section 4.5
for information about recooling the
cooling water. This process should be carried out in
the vehicle by means of a forced-circulation cooling
system with rotary pumps and coolers.

These data apply for:
Surrounding temperature 30°C
Continuous operation
Winter operation with anti-freezing compound
Summer operation without anti-freezing compound
If the anti-freezing compound remains in the cooling
system during summer operation, it is necessary to
increase the volume flow of the cooling water by ca.
15%. Otherwise the lower heat dissipation presents
the danger of overheating.
Max. Permissible cooling water temperature
in the cooling water circuit is 60°C.
Drive methods
From the vehicle engine:
By auxiliary drive and drive shaft
By V belt; the drive belt disk being mounted onto the
free end of the drive shaft
By a pneumatic shift clutch
By a hydromotor
From a diesel or electric engine
By an elastic coupling
4.6, drive.
