Air conditioner switch
1. Push this switch to activate the air conditioner. An
indicator light will light up when the switch is set to
“ON”.
2. Push the switch again to turn the air conditioner off,
in which case the indicator light will be off.
NOTE :
• With the blower switch at the [OFF] position, the
indicator light will not light up even when the
air-conditioner-switch is set to “ON”
IMPORTANT :
• To operate the air conditioner after the tractor
has not been used for one week or longer, run
the engine at idling speed first and then set the
air-conditioner-switch to “ON”. Keep this for
one minute or so.
If the air-conditioner-switch is set to “ON” with
the engine running at high rpm, the compressor
may get in trouble.
Recirculation / fresh air selection switch
Each time the switch is pressed, the air flow position
changes for “RECIRCULATION” or “FRESH AIR”. An
indicator light will light up when the switch is set to
“RECIRCULATION”. And the indicator light will be off
when the switch is set to “RECIRCULATION”.
FRESH AIR: (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.
(1) Recirculation / fresh air se-
lection switch with indicator
light
(A) Recirculation
(B) Fresh air
NOTE :
• When heating, do not keep the switch at the
“RECIRCULATION” position for a long time. The
windshield easily gets foggy.
• While working in a dusty conditions, keep the
switch at the “FRESH AIR” position. This
increases the pressure in the CAB, which helps
prevent dust from coming into the CAB.
4. Operation of the air conditioner
4.1 Heating
1. Set the recirculation / fresh air selection switch to

in the CAB quickly, set this switch to the
“RECIRCULATION” position.
