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 failure. Take care not to let wa-
ter get on them. In addition, never bring any open flame near them.
• Always keep the sunlight sensor clean so that the auto function of the air conditioner can work
properly. Do not leave anything around the sunlight sensor that may interfere with its sensor func-
tion.
When the air conditioner is not used every day, to prevent loss of the film of oil at various parts, run the air con-
ditioner 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 the recircu-
lation air to warm the inside of the cab. After that, turn on the air conditioner switch, and 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 machine monitor screen. If the air conditioner
system caution lamp lights up, ask your Komatsu distributor for
inspection and repair.
Ventilation while cooling
• 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 cooling to drive smoke out.
Temperature control
For reasons of health, it is said that the optimum setting for cooling is the temperature when it is slightly cool (5
to 6 °C lower than the ambient temperature) when you enter the cab.
Be careful to select the appropriate temperature.
