Routine Maintenance

Air Conditioning System (If Equipped)
Compressor
During cold weather if the air conditioner has not
been used for at least 30 days, operate the air
conditioner for a period of 10 to 15 minutes, at an
engine speed of 1500 rpm. This will lubricate the
seals to prevent them becoming brittle and help
prevent the loss of refrigerant from the system.
IMPORTANT:
This tractor is equipped with HFC-
134a refrigerant, which will not destroy the ozone
layer. Never recharge the air conditioning system
with refrigerant other than HFC-134a as this will
result in loss of cooling and permanent damage to
all air conditioning components.
System Check
Tractors equipped with a Standard Type
Air Conditioning System
DD95M222
If the air conditioner indicator lamp (1) illuminates,
check the following possible causes.
A. Cold ambient temperature (turn thermostat
switch or blower switch off then back on to
desired setting).
B. Restricted condenser.
C. Restricted evaporator.
D. Low air flow (dirty filter or restriction).
See your dealer if problem continues.
Rapid on/off illumination of the lamp indicates a
problem with the system and if left could result in
damage to the compressor clutch. If this occurs do
not use the air conditioning until it has been
serviced by your dealer.

If the system fails to function correctly the service
indicator (A) will illuminate and an error code will
be displayed in the Temperature Setting Display
(B).
NOTE: The display will alternate between the
recorded error code and the temperature setting.
Report all error codes to your dealer.
GENERAL MAINTENANCE
WARNING: Never attempt to open the air
conditioning system. Liquid refrigerant can
cause severe and painful frostbite. Contact
your dealer, who is experienced in
servicing and handling of refrigerants.
