    For this reason, we do not recommend the old practice of topping off a partially discharged air conditioning system using the sight glass. The Farmall 40C/50C cab tractors use 700 g (25 oz) of R134 refrigerant.
  • Page 14 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.
  • Page 15 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.
  • Page 16 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.
  • Page 17 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.
  • Page 18 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 Farmall 40C, and 50C cab tractors use 1.0 kg (2.2 lb) of R134a refrigerant.
  • Page 19 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.
  • Page 20 INTRODUCTION 8. After making certain that container temperature has again stabilized to room temperature, repeat step 4 above. If the pressure exceeds that in the table for the storage temperature you measured, the refrigerant in the tank has too much excess air to be used and must be recycled or reclaimed. If the refrigerant being checked has been contaminated with other refrigerant such as R12, the tank pressure may indicate it contains air.
  • Page 21 INTRODUCTION APPLICABLE SAE STANDARDS J639 - Safety and containment of refrigerant for mechanical vapor compression systems used for mobile air condi- tioning systems J1989 - Recommended service procedure for the containment of R12 J1991 - Standard of purity for use in mobile air conditioning systems J2099 - Standard of purity for recycled R134 for use in a mobile air conditioning system J2196 - Service hose for automotive air conditioning...

    INTRODUCTION Safety rules – Personal safety Farmall® 40C Farmall® 50C General safety rules Read this manual carefully before starting, using carrying out maintenance, refueling or performing any other type of operation on the tractor. Read all the safety decals on the tractor and follow the instructions thereon before starting, operating, refueling or carrying out maintenance on the tractor.
  • Page 23 INTRODUCTION Never operate engine in enclosed spaces as harmful exhaust gases may build up. Before starting the tractor, be sure that all controls are in neutral or park lock position. Before starting the engine, make sure that all attached implements are lowered to the ground. Start the engine only from the operator’s seat.
  • Page 24 INTRODUCTION Before leaving the tractor: 1. Park tractor on a firm level surface. 2. Put all controls in neutral or park lock position. 3. Engage park brake. Use wheel chocks if required. 4. Lower all hydraulic equipment — Implements, header, etc. 5.
  • Page 25 INTRODUCTION Unsupported hydraulic cylinders can lose pressure and drop the equipment causing a crushing hazard. Do not leave equipment in a raised position while parked or during service, unless securely supported. Jack or lift the tractor only at jack or lift points indicated in this manual. Incorrect towing procedures can cause accidents.
  • Page 26 INTRODUCTION Replace damaged or worn tubes, hoses, electrical wiring, etc. Engine, transmission, exhaust components, and hydraulic lines may become hot during operation. Take care when servicing such components. Allow surfaces to cool before handling or disconnecting hot components. Wear protective equipment when appropriate.
  • Page 27 INTRODUCTION Make sure brake pedal latch is engaged. Brake pedals must be locked together for road travel. Use safety chains for trailed equipment when provided with tractor or equipment. Lift implements and attachments high enough above ground to prevent accidental contact with road. When transporting equipment or tractor on a transport trailer, make sure it is properly secured.
  • Page 28 INTRODUCTION Using implements and agricultural machinery 1. Do not connect implements or machinery that require more power than can be generated by your tractor model. 2. Never negotiate sharp turns with the power take-off under a heavy load; this may damage the universal joints on the transmission shaft connected to the power take-off.
  • Page 29 INTRODUCTION Battery post, terminals, and related accessories contain lead and lead compounds. Wash hands after handling. This is a California Proposition 65 warning. Battery acid causes burns. Batteries contain sulfuric acid. Avoid contact with skin, eyes, or clothing. Antidote (ex- ternal): Flush with water.
  • Page 30 INTRODUCTION • Clean belts only with soap solution and warm water. • Do not use bleach or dye on the belts because this can make the belts weak. • For proper seat belt use, see the Operator’s Manual. 47941906 16/03/2016...
  • Page 31 INTRODUCTION Operator protective structure Your tractor is equipped with an operator protective structure, such as: a Roll Over Protective Structure (ROPS), Falling Object Protective Structure (FOPS), or a cab with ROPS. A ROPS may be a can frame or a two-posted or four-posted structure used for the protection of the operator to minimize the possibility of serious injury.
  • Page 32 INTRODUCTION Personal Protective Equipment (PPE) Wear Personal Protective Equipment (PPE) such as hard hat, eye protection, heavy gloves, hearing protection, pro- tective clothing, etc. Do Not Operate tag Before you start servicing the tractor, attach a ‘Do Not Operate’ warning tag to the tractor in an area that will be visible. Hazardous chemicals If you are exposed to or come in contact with hazardous chemicals you can be seriously injured.
  • Page 33 INTRODUCTION Electrical storm safety Do not operate tractor during an electrical storm. If you are on the ground during an electrical storm, stay away from machinery and equipment. Seek shelter in a permanent, protected structure. If an electrical storm should strike during operation, remain in the cab. Do not leave the cab or operator’s platform. Do not make contact with the ground or objects outside the tractor.
