40 and 50 tractors. Use this manual in conjunction with the operator's manual for complete operation, adjustment, and maintenance information On NEW HOLLAND equipment, left and right are determined by standing behind the unit, looking in the direction of travel.
INTRODUCTION Safety rules Personal safety This is the safety alert symbol. It is used to alert you to potential personal injury hazards.

Throughout this manual you will find the signal words DANGER, WARNING, and CAUTION followed by special in- structions.
Improper disposal of batteries can contaminate the soil, groundwater, and waterways. NEW HOLLAND strongly recommends that you return all used batteries to a NEW HOLLAND dealer, who will dispose of the used batteries or recycle the used batteries properly. In some countries, this is a legal requirement.

INTRODUCTION CONTAMINANTS General No mobile air conditioning system can operate for long without picking up some contaminants in the refrigerant. The flexible hoses, for example, allow moisture and air to migrate into the refrigerant from the outside atmosphere. Mois- ture and non-condensable gases (air) are the most common contaminants found in mobile air conditioning systems. NOTICE: Contaminating R134 with R12 or CFC will lead to copper plating of steel components and major compres- sor failure.

INTRODUCTION Recycling equipment meeting SAE standards J1990 and J2210 is designed to extract and recycle refrigerants that have been in mobile air conditioning systems only. R134 refrigerant that also is used in non-mobile systems may introduce contaminants to the refrigerant that equipment meeting SAE J1990 and J2210 cannot remove. This equip- ment is not intended for use on non-mobile systems.

INTRODUCTION CONTAINMENT OF AIR CONDITIONING REFRIGERANTS The following procedure is a guide to servicing mobile air conditioning systems in a way that minimizes the potential for losing refrigerant to the atmosphere. Following the procedures in this section will help ensure compliance with SAE J2211 for R134 systems.

INTRODUCTION 10. Determine the amount of lubricant removed from the air conditioning system during the refrigerant extraction process. Replenish the air conditioning system with an equal volume of new, correct lubricant. 11. The system is now ready for service or repair. Flushing Flushing needs to be performed when the compressor is replaced due to internal parts failure, or when a desiccant bag deteriorates and desiccant travels throughout the system.

INTRODUCTION Recharging/Refilling Recharge the system only with the proper virgin refrigerant or recycled refrigerant purified to meet SAE purity standard (J2099 for R134 ). Use the weight method to determine the proper amount of refrigerant. The Boomer 45/50/55 cab tractors use 1.0 kg (2.2 lb) of R134a refrigerant. 48144020 23/06/2017...

INTRODUCTION Using a Manifold Gauge Set When using a manifold gauge set to diagnose, recharge, or service the tractor air conditioning system: 1. Be sure that all equipment hose lines are fitted with shutoff valves or check valves within 30 cm (12 in) of their ends and that the valves are closed.
