The auxiliary heater switches itself on and the insert lights up.
The auxiliary heater only supports the heating capacity of the standard heat-
ing system as long as the engine is cold. If the engine is warm, the heater is
switched off. However, the pump for the auxiliary heater continues to run
until you switch the auxiliary heater off.

Always switch the auxiliary heater off if you switch off the truck crane whilst
the battery master switch is switched on. In this way, you prevent the auxil-
iary heater from restarting and the batteries from running down after the
engine has cooled down.

auxiliary heater

auxiliary heater is switched off again after a certain heating period if it was
