Operating Manual GMK6300L
Adjust the heating system as follows if the driver's cab is to be preheated in
addition to the engine:
•
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).
•
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.
•
Switch (2) to position Warm .
•
Switch (1) on the recirculated air symbol,
level 1.
