(2) Normal operation
To dehumidify the cab for increased comfort.
① Slide the temperature controller to the desired position.
②
Slide the fan controller to the desired position.
・
If the air inside the cab becomes dirty, such as with cigarette smoke, open the window.
・ If the temperature controller is set to "Max" and the fan controller to "Low", when the
compressor rpm is high or humidity is high, frost may form on the cooling system and reduce
the air flow.
If this occurs, moving the temperature controller to the lowest setting (while maintaining air
flow) will remove the frost.

3-5-3 Operating precautions
(611A-0013-0E)
(1) Parking in hot sun
If parked in the hot sun for an extended period, the interior temperature will become very high.
If this occurs, open the windows completely and ventilate the hot air, then operate the air conditioner. Once the
interior air begins cooling down, close the windows and adjust the air conditioner to the desired temperature.
(2) Scratchy eyes
Smoking in the cab with the windows closed and the air conditioner on may cause eye irritation, but this is due to
the dry interior air drying out the viscous film on the eyes and making them more prone to irritation.
If this occurs, open the windows and ventilate the smoke.
(3) Appropriate cooling temperature
The air conditioner provides a comfortable atmosphere by lowering the temperature and reducing humidity.
Normally, a temperature that feels slightly cool when entering the cab is considered optimal for health (about 5 or
6 ℃ cooler than the outside air temperature).
Cooling the air too much may have various detrimental health effects. Therefore, choose the temperature setting
carefully.
(4) If the glass becomes foggy
Glass can fog up especially easily on rainy days and can reduce visibility.
This fogginess can be removed by operating the air conditioner.
