If water gets into the control panel or sunlight sensor, unexpected failure may occur. Take care not
to let water get on these parts. In addition, never bring any open flame near them.
•
In order that the automatic operation of the air conditioner is effective, always keep the sunlight
sensor clean and avoid leaving any objects nearby that could interfere with the sensor functions.

loss of the film of oil at various parts, run the air condition-
er with the engine at low speed from time to time and per-
form cooling or dry heating for several minutes.

tioner may not work. In this case, recirculate the air to heat
the inside of the cab. After that, turn the air conditioner
switch ON, the air conditioner will work.
