3.2.14 Air conditioner
(Option)
NOTICE
Only use the air conditioner when the engine is running. Let the
air conditioner run for about 10 minutes every month to prevent
the compressor shaft seal from drying out.
Do not let the air conditioner run for an extended period of time at
low engine speeds to prevent the battery from discharging.
Keep the cab doors and windows closed when the engine is run-
ning.
If the machine was exposed to strong sunlight for an extended
period of time, it is recommended to air the cab thoroughly when
starting the machine and turning on the air conditioner.
Turning on the air conditioner
1. Turn the fan switch (1) to position '4'.
2. Turn the temperature control switch (2) to 'cold'.
3. Activate the air conditioner switch (3).
The air conditioner is now on. This setting achieves the great-
est cooling effect, especially if the engine is running at high
speed.
4. Turn the fan switch (1) back one position when the desired
temperature has been reached.
5. Use the temperature dial for further adjustment.
6. The air is distributed by means of air outlet nozzles (a).
 You can open and close all air outlet nozzles (a) individu-
ally.
 The airflow may be directed with the diffuser discs.
 The air outlet nozzles (a) can be directed at the wind-
screen and at the side windows.
