Preheating the
driver's cab
Adjust the heating system as follows if the driver's cab is to be preheated in
addition to the engine:
• Switch (2) to position Warm.
• Switch (1) on the recirculated air symbol,
level 1.
• Open the air vents; à p. 5 - 76.
• Knob (3) pulled.
If you heat the driver's cab at the same time,
the amount of time required to preheat the
engine will increase significantly.
Switching on the
auxiliary heater
• Check whether the auxiliary heater is allowed to be operated at the cur-
rent site of the truck crane before switching it on. Find out whether there
are any possible sources of danger that could result in an explosion.
• Turn the switch (1) to the required temperature.
If the switch (1) is turned as far as possible (A) (
cold), the auxiliary heater is
not switched on.
