Tips for Optimal Air Conditioner Usage
For Rapid Cooling
Temperature in the cab may rise over 80 °C (176 °F) when
the machine is exposed to sun light in the summer.
In this case, ventilate air in the cab first by opening the
windows for rapid cooling.
After starting the engine, press AUTO switch (6).
Set temperature to "18.0" on the monitor by using
temperature control switch (5). Turn circulation mode
ON from air conditioner setting screen on the monitor.
Close the window when the cab cools down to the
ambient temperature.
When Windows Become Fogged
If the insides of the windows become fogged during
rainy weather or on humid days, operate the air
conditioner to aid in keeping the windows clear.
When the atmosphere is very damp, and if the air
conditioner has run excessively, the outside of the
windows may become fogged. If this happens, turn up
the air temperature selection to adjust the temperature
in the cab.
Off-Season Air Conditioner Maintenance
To protect each part of the compressor from a lack of
lubricant, operate the air conditioner at least once a
month for several minutes with the engine running at a
slow speed during off-season.
IMPORTANT:

Refer to the item "Check Air Conditioner Filter" in
the Maintenance Section for maintenance of the
air conditioner filters.

Always clean the auto air conditioner sensor for
effective air conditioner performance. Avoid
placing any obstructions around the sensor.
