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, push AUTO/OFF switch (6). Set
temperature to "18.0" on the monitor by using temperature
control switch (5). Turn air circulation mode ON from air
conditioner setting screen on the monitor.
Close the windows when the cab cools down to the
ambient temperature.
When Windows Become Misty
If the insides of the windows become misty 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 misty. If this happens, turn off the air
conditioner 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:
Do not suddenly increase the engine speed. Failure
to do so may damage the compressor.
Refer to the item "Check Air Conditioner Filter" in
the Maintenance Chapter 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.
