AIR CONDITIONER MAINTE-
NANCE
Make sure to follow the instructions
below to keep the air conditioner in
the best condition:
1. Operation in winter season:
During the winter time, run the
air conditioner once or twice ev-
ery month to prevent refrigerant
leakage and corrosion in the air
conditioner system and to facilitate
oil circulation in the compressor in
order to prevent malfunction.
The A/C does not operate when
the air temperature is below 2 É.
Therefore, warm the inside air by
operating the heater in order to be
able to operate the A/C.
2. Air conditioner condenser care:
If there is foreign material in the A/
C condenser and engine radiator,
their cooling performance may be
deteriorated. Therefore, always
keep them clean for their optimal
cooling performance. When clean-
ing the core of the condenser, use
WARNING
• If you sleep with the air condi-
tioner or heater in operation,
you may be su󰀨ocated to death.
• If keeping the A/C on for an ex-
tended period of time, inside air
can become impure. Therefore,
draw outside air and ventilate
the cabin regularly.
CAUTION
• Keep the windows closed while
the A/C is in operation for e󰀨ec-
tive operation.
• Turn o󰀨 the air conditioner for
better engine power when the
work load rapidly increases.
• When the tractor is stationary
and being used in high load
work, reduce the A/C operation
period as the engine may be
overheated.
• Make sure you operate the
air conditioner once or twice
a month in winter season to
prevent refrigerant leakage
and facilitate the compressor
lubrication for durability of the
A/C compo-nents.
• If the tractor has been parked
under strong sunlight for a
long period of time, open the
windows to ventilate the cabin
before operating the A/C.
