3.2.13 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. Open all air intake nozzles (b), if equipped.

decreases.
2. Turn the fan switch (1) to position '4'.

temperature has been reached.
6. Use the temperature dial for further adjustment.
