Air-conditioning system
You can cool the driver's cab and dry the air using the air-conditioning
system.
Notes Do not cool the air too much.
The difference between the outside temperature and the inside temperature
should be at the most 10 °C to 14 °C (18 °F to 25 °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.
When using recirculated air, you should switch over to fresh air mode to
ensure a fresh supply of oxygen at the same time. Adjust the cooling output
to your actual needs:
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. The cooling-down procedure can be accelerated by
increasing the engine speed.
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.
