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.
