(Indicator: OFF)
Fresh air will flow into the CAB.
This is helpful when you work in
dusty conditions or if the glass
windows get foggy.
RECIRCULATION:
(Indicator: ON)
In-CAB air will be recirculated.
This is useful for cooling or heating
the CAB quickly or keeping it extra
cool or warm.
C Blower Switch
Air volume can be changed in 4 steps. At the "4" position,
the largest air volume is obtained.
C Air Conditioner Switch
Push this switch to activate the air conditioner. An
