OPERATION EXPLANATION OF COMPONENTS COOLING OPERATION When the cooling operation is carried out, the inside of the cab is cooled, and at the same time the drinks inside the hot and cool box can be cooled. COOLING (RECIRC) When the control switch and lever are operated as shown in the diagram, a cool breeze is sent out. Use this position when strong cooling is needed. Press swith (2). Place levers (1) and (4) in the position shown in the dia- gram. Set switch (3) to the desired position. COOLING (FRESH) If the air inside the cab is no longer fresh, set FRESH/RECIRC selector lever 1 to FRESH to bring in fresh air. Keep the other switches at the same positions as for cooling (RECIRC).
In this position, the inside of the cab is pressurized to prevent the entry of dust. REMARK If the cooling effect is reduced, set FRESH/RECIRC selector lever (1) to RECIRC again. This increases the cooling effect. 3-35
