8.2.4 PRECAUTION IN USE OF AIR CONDITIONER
・
The air conditioner should be turned on after the engine is started, avoiding an excessive load on
the engine or compressor.
・
Use the air recirculation if there is dust or stench in the environment around the machine.
・
To avoid freezing of the evaporator, do not operate the air conditioner for a long time with the
lowest temperature setting.
・
If it freezes and cooled air does not come out, stop the air conditioner. Set the temperature higher,
and operate it for a while in the airflow "3".
・
Open the doors or windows to replace hot air in the cab with fresh air before using the air
conditioner if the temperature is high.
・
The engine coolant is used for heating, and it is possible to heat the air when the temperature of
the coolant is high.
・
For your health, do not overcool the cab and catch cool air directly on the skin for a long time.
Sometimes ventilate the cab.
8.2.5 PRECAUTION IN INSPECTION AND MAINTENANCE OF AIR CONDITIONER
・
Have an inspection and maintenance of the air conditioner to achieve the best performance of it
and use it in good condition.
・
Dedicated tools and instruments are needed for making up the refrigerant gas and other
maintenance. Contact our authorized dealer/distributor.
・
Operate the air conditioner for a few minutes about two or three times a month even in the
off-season not to run out of oil in the compressor.
・
Check the refrigerant gas for leakage. If the leakage is left as it is for a long time, rust will occur
inside, which causes a failure.
・
Keep electrical components of the air conditioner parts away from water when cleaning in the cab.
If water gets through, rust will occur inside, which causes a failure.
