Servicing Air Conditioner

CAUTION: Escaping refrigerant under pressure can penetrate eyes and skin causing serious injury to you or others. Do not attempt to repair or service refrigerant system. (See your John Deere dealer.)

IMPORTANT: R134a refrigerant must be used. This requires special equipment and procedures. (See your John Deere dealer.)

NOTE: Some oil seepage from compressor shaft seal on the lower front is normal.

Check the following if air conditioner will not cool or cooling is intermittent:

If air conditioner clutch slips after machine has been in storage, compressor may be stuck. Stop engine and turn key switch to OFF position. Rotate clutch hub back and forth to free compressor.

NOTE: Fan speed switch (B) must be in an ON position before air conditioning will operate.

Place throttle switch in middle throttle position (1700 rpm). Rotate temperature adjust switch (A) to the right for air conditioning. Rotate fan speed switch (B) to the right to increase fan speed.

If cooling is intermittent, clean rotary screen, radiator, and condenser. If problem is not solved, (See your John Deere dealer.)

Inspect cab body filters for restriction. Clean filters. If problem persists, (see your John Deere dealer to have evaporator core cleaned).
