FUNCTIONING
AIR CONDITIONER
3-99
USE THE AIR CONDITIONER WITH CAUTION 3
NOTICE
q
Before switching on the air conditioner, ensure that the engine is running at low speed. Never switch
the air conditioner on while operating at high speed. This will damage the air conditioner.
q
Water entering the control panel or the sunlight sensor will cause a sudden malfunction; keep water
away from these components. Keep open flame away from these components.
q
To ensure correct operation of the air conditioner in automatic mode, keep the sunlight sensor clean
and unobstructed at all times.
Ventilation 3
q
When using the air conditioner for extended periods, set the lever to FRESH at least once every hour for
correct ventilation and optimum cooling.
q
Smoking with the air conditioner on may cause irritation to the eyes; to expel the smoke without turning off the
air conditioner, open the window and set the lever to FRESH briefly.
Temperature control 3
When the cooling function is on, set the temperature to obtain a slightly cool sensation when entering the cab (5 or
6 °C less than the external air temperature). Setting the correct temperature is very important as an excessive
temperature difference is considered unhealthy.
INSPECTING AND SERVICING A MACHINE WITH AIR CONDITIONER 3
q
When inspecting or servicing vehicles with air conditioning, proceed as described in the relative guidelines.
For more details, see "AIR CONDITIONER MAINTENANCE AND CHECKING (4-35)", "CHECKING AND
ADJUSTING THE AIR CONDITIONER COMPRESSOR BELT TENSION (4-52)", "CLEANING THE AIR
CONDITIONER FILTERS (4-65)".
q
If the air conditioner is not used daily, to prevent the
deterioration of the oil film on certain components,
occasionally operate the cooling or heating function of the
air conditioner for a few minutes with the engine at low
speed.
q
The air conditioner will not function if the internal cab
temperature is too low. If this occurs, circulate fresh air in
the cabin to warm the air. If the air conditioner button is
ON, the air conditioner will start functioning.
q
Any malfunction detected in the air conditioner system or
sensors will be indicated on the monitor by the message
“A/C Controller Error“. If the message “A/C Controller
Error“ is displayed, ask your Komatsu distributor to inspect
and repair the system.
