10.9.2 Air-conditioning system
You can use the air-conditioning system to cool and dry the air in the
crane cab.
Information Do not cool the air in the crane cab too much.
The difference between the outside temperature and the inside temperature
should be at the most 10 °C to 14 °C (50 °F to 57.2 °F).
If the cooling is too severe, you may frequently feel physically uncomforta-
ble, albeit mostly only after you leave the cool environment.
Avoid having cold air blowing directly on to your body.
If the truck crane has been exposed to strong sunlight for a long period of
time, for example, the air-conditioning system should initially be operated
at the highest blower level with the engine running.
The door or at least the windows should be left open for a short while to
thoroughly air the cab.
If the air-conditioning system is operated continuously, close the windows
and doors to ensure sufficient cooling.
Once the inside temperature has reached the desired temperature, set the
fan to a lower level.
