Cab Heat Control – Optional Cab
During the colder months, the operator’s cab heater can
be turned on by rotating the dial near the vent (Figure
3-30). On older models, turn on the cab heater by open-
ing the heater valve located under the hood on top of
the engine behind the radiator (Figure 3-31). Rotate the
lever to either the “heat on” or “heat off” position as
required.
Note: The recirculated air mode vent is a storage
compartment on the canopy model machines.

Recirculated Air Mode
When heating or cooling the cab, the recirculated air
mode can be utilized to heat or cool only the air in the
cab with no fresh air supply from the outside. Sliding
the plate to the left will turn ON the recirculated air
mode by closing the vent. Sliding the plate to the right
will turn OFF the recirculated air mode by opening the
vent. Figure 3-32 shows the unit with recirculated air
mode turned OFF.
