Check pipe connections for refrigerant gas leakage
If oil seepage is found around pipe connections, it indicates
possible gas leakage.
Check Refrigerant
Start the engine and run at approximately 1500 min
-1
(rpm).
Turn the air conditioner switch to ON. Set the blower switch
to HI and set the temperature control switch to the coolest
position (18 °C on the monitor screen). Operate the air
conditioner for 2 to 3 minutes. Check if cool air comes out
from the vent in the cab.

IMPORTANT: Do not dispose FREON gas into the
atmosphere to prevent depletion of the ozone layer
and global warming.
Check the condenser
If the condenser fins become clogged with dirt or insects,
the cooling effect will be decreased.
Be sure to keep them clean at all times. (Refer to "Clean
Radiator/Oil Cooler Core" in Maintenance Section.)
Check compressor
After operating the air conditioner for 5 to 10 minutes,
touch both the high pressure pipe and the low pressure
pipe.
If normal, the high-pressure side pipe will be hot, and the
low-pressure side cold.
