CAUTION: Avoid possible injury. Improper servicing may cause refrigerant to penetrate eyes and skin or cause burns.

IMPORTANT: R-134a refrigerant must be used in air conditioning system. Service requires special equipment and procedures. See your John Deere™ dealer.

NOTE: Some oil seepage from compressor shaft seal is normal.

Perform following checks if air conditioning system will not cool, or cooling is intermittent:

• Confirm system does not function correctly. Access HVAC page on CommandCenter™ (see Generation 4 CommandCenter™ HVAC Settings in Operator Station section of this Operator’s Manual). Set fan increment bar (A) to highest speed. Access Set Temperature page (B) and set temperature to coldest setting (C). Operate engine at 2000 rpm. Check air vents. If air is not significantly cooler than ambient cab air temperature, problem exists.
• Inspect and clean cab air filters. Replace filters if necessary. See Clean or Replace Cab Air Filters in this section of this Operator’s Manual.
• Clean grille and radiator. See Clean Radiator, Coolers and Air Conditioning Condenser in this section of this Operator’s Manual.
• Check air vents for cold air flow.

If problems persist, see your John Deere™ dealer.
