If you smoke when the cooler is on, the smoke may start to hurt your eyes, so turn the lever to FRESH to remove the smoke while continuing the cooling.
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. Be careful not to make the temperature in the cab too low. When the cooler is on, set the temperature so that it feels slightly cool when entering the cab (5 – 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. 11.11.3 CHECK, MAINTAIN MACHINE EQUIPPED WITH AIR CONDITIONER When carrying out inspection and maintenance of a machine equipped with air conditioner, see “23.1 MAINTENANCE SCHEDULE CHART”. 2-32
