NOTICE
q When running 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.
q If water gets into the control panel or sunlight sensor, it may lead to unexpected failure, be careful not
to let water get on these parts. In addition, never bring any flame near these parts.
q For the auto function of the air conditioner to work properly, always keep the sunlight sensor clean
and do not leave anything around the sunlight sensor that may interfere with its sensor function.
Ventilation
q When running the air conditioner for a long time, turn the lever to the FRESH position once an hour to carry out
ventilation and cooling.
q If you smoke when the air conditioner is on, the smoke may start to hurt your eyes, so open the window and turn
the lever to FRESH for a while to remove the smoke while continuing the cooling.
Temperature Control
When the cooler is on, set the temperature so that it feels slightly cool when entering the cab (5 or 6 °C) lower than
the outside temperature). This temperature difference is considered to be the most suitable for your health, so
always be careful to adjust the temperature properly.
