Servicing Air Conditioner (Cab)

causym CAUTION: Refrigerant under pressure. Improper servicing may cause refrigerant to penetrate eyes and skin or cause burns.

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 if cooling is intermittent:

1. If air conditioner clutch slips after tractor has been in storage, compressor may be stuck.

a. Stop engine and turn ignition switch to STOP (off) position.

b. Raise hood and rotate clutch hub back and forth to free compressor.

3. Inspect operator enclosure (cab) filters for restriction. Clean filters. (See procedure in this section.) If problem persists, see your John Deere dealer to have evaporator core cleaned.
