OPERATION CAB ENVIRONMENT AND SAFETY EQUIPMENT Ventilating, cooling and heating the cab serve to reduce operator discomfort in cold or hot environments. If your machine is equipped with a cab this system serves to reduce condensation on cab windows and uncomfortable temperature conditions. HEATING AND VENTILATION SYSTEM AIR CONDITIONING If your machine is equipped with air conditioning, besides the air condi- tioning switch (16) and blower control switch (18) you will have two other controls. These controls are (T) for temperature control and (R) for re-circulate. To control temperature (T) simply turn the knob clockwise to increase temperature and counter-clockwise to decrease temperature.
To regulate air supply (R) turn knob clockwise to re-circulate inside cab air and counter-clockwise to allow outside air in. Feature (R) is so the cab can be warmed up or cooled down rapidly. HEATING SYSTEM If your machine does not have the optional air conditioning it will still have the temperature control switch (T) and the blower control switch.To control temperature (T) simply turn the knob clockwise to increase temperature and counter-clockwise to decrease temperature. Inside cab air is picked up through vent (5) and circulated past the heater core. Vents (1) supply the rear and front of the cab. Front And Side Air Supply Vents (1) WB140-2N, WB150-2N 2-21
