Operating Manual GMK6300L
•
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.
Risk of explosion when operating the auxiliary heater!
The auxiliary heater is not allowed to be operated:
– at service stations and tank farms,
– at places where flammable gases or vapours can be found or formed
(e.g. at places where fuel is stored and in chemical factories),
– at places where explosive dust can be found or formed (e.g. carbon dust,
wood dust and grain dust).
Danger of suffocation when operating the auxiliary heater!
Do not use the auxiliary heater in closed spaces (e.g. a garage).
This section describes how to switch on the heater manually. The auxiliary
heater can also be switched on automatically;
p. 11 - 138.
•

•
Press the button (1) once.
The auxiliary heater switches on automatically – the control field lights up.
Setting the temperature
•
Turn switch (1) to the desired temperature.
If the switch (1) is turned as far as possible (2) ( cold ), the auxiliary heater is
not switched on.
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.
