HANDLE AIR CONDITIONER
NOTICE
• When performing running-in of the air conditioner, always start with the engine running at low
speed. Never start the air conditioner when the engine is running at high speed. It will cause failure
of the air conditioner.
• If water gets into the control panel or sunlight sensor, it may lead to unexpected failure, take care
not to let water get on these parts. In addition, never bring any open flame near them.
• For the auto function of the air conditioner to work properly, always keep the sunlight sensor clean
and do not leave anything around the sunlight sensor that may interfere with its sensor function.
When the air conditioner is not used every day, to prevent loss
of the film of oil at various parts, run the air conditioner with the
engine at low speed from time to time and perform cooling or
dry heating for several minutes.
When the temperature inside the cab is low, the air conditioner
may not work. In this case, circulate recirculation air to warm
the inside of the cab. After that, turn the air conditioner switch
ON, the air conditioner will work.
If any abnormality is detected in any equipment or sensor used
on the air conditioner, the air conditioner system caution lamp
lights up on the monitor screen. If the air conditioner system
caution lamp lights up, ask your Komatsu distributor for inspection and repair.
Ventilation
• When running the air conditioner for a long time, turn the lever to FRESH position once an hour to perform
ventilation and cooling.
• If you smoke when the air conditioner is on, the smoke may hurt your eyes. In such case, open the window
and turn the lever to FRESH for a while for ventilation and driving smoke out.
Temperature control
For reasons of health, the optimum setting for cooling is considered to be when it feels slightly cool (5 to 6 °C
lower than the ambient temperature) when you enter the cab.
Be careful to select the appropriate temperature.
If the cold air form the air conditioner blows directly against the machine monitor, water may condense on the
machine monitor screen. In this case, change the angle of the vent.
