INSTALLATION OF ADJUSTABLE FITTINGS IN STRAIGHT THREAD O RING BOSSES

  1. Lubricate the O-ring by coating it with a light oil or petroleum. Install the O-ring in the groove adjacent to the metal backup washer which is assembled at the extreme end of the groove (4).
  2. Install the fitting into the SAE straight thread boss until the metal backup washer contacts the face of the boss (5).
    NOTE: Do not over tighten and distort the metal backup washer.
  3. Position the fitting by turning out (counterclockwise) up to a maximum of one turn. Holding the pad of the fitting with a wrench, tighten the locknut and washer against the face of the boss (6).

Before installing and torquing 37° flared fittings, clean the face of the flare and threads with a clean solvent or Loctite cleaner and apply hydraulic sealant to the 37° flare and the threads.
Install fitting and torque to specified torque, loosen fitting and retorque to specifications.

PIPE THREAD FITTING TORQUE
Before installing and tightening pipe fittings, clean the threads with a clean solvent or Loctite cleaner and apply sealant for all fittings including stainless steel or for most metal fittings. For high filtration/zero contamination systems use.

INSTALLATION OF ORFS (O-RING FLAT FACED) FITTINGS

When installing ORFS fittings thoroughly clean both flat surfaces of the fittings (1) and lubricate the O-ring (2) with light oil. Make sure both surfaces are aligned properly. Torque the fitting to specified torque listed throughout the repair manual.
NOTICE: If the fitting surfaces are not properly cleaned, the O-ring will not seal properly. If the fitting surfaces are not properly aligned, the fittings may be damaged and will not seal properly.
NOTICE: Always use genuine factory replacement oils and filters to ensure proper lubrication and filtration of en- 50011183 2 gine and hydraulic system oils.
The use of proper oils, grease, and keeping the hydraulic system clean will extend machine and component life.

Safety rules

Personal safety

Carefully study these precautions, and those included in the external attachment operators manual, and insist that they be followed by those working with and for you.

  1. Thoroughly read and understand this manual and the attachment Operator's Manual before operating this or any other equipment.
  2. Be sure all people and pets are clear of the machine before starting. Sound the horn, if equipped, three times before starting engine.
  3. Only the operator should be on the machine when in operation. Never allow anyone to climb on to the machine while it is in motion. If the machine is equipped with an Instructors Seat, this must only be used for training purposes. Passengers must not be allowed to use the Instructors Seat.
  4. Keep all shields in place. Never work around the machine or any of the attachments while wearing loose clothing that might catch on moving parts.
  5. Observe the following precautions whenever lubricating the machine or making adjustments.
    • Disengage all clutching levers or switches.
    • Lower the attachment, if equipped, to the ground or raise the attachment completely and engage the cylinder safety locks. Completing these actions will prevent the attachment from lowering unexpectedly.
    • Engage the parking brake.
    • Shut off the engine and remove the key.
    • Wait for all machine movement to stop before leaving the operators platform.
  6. Always keep the machine in gear while travelling downhill.
  7. The machine should always be equipped with sufficient front or rear axle weight for safe operation.
  8. Under some field conditions, more weight may be required at the front or rear axle for adequate stability. This is especially important when operating in hilly conditions or/when using heavy attachments.
  9. Always lower the attachment, shut off the engine, set the parking brake, engage the transmission gears, remove the key and wait for all machine movement to stop before leaving the operators platform.
  10. If the attachment or machine should become obstructed or plugged; set the parking brake, shut off the engine and remove the key, engage the transmission gears, wait for all machine or attachment motion to come to a stop, before leaving the operators platform to removing the obstruction or plug.
  11. Never disconnect or make any adjustments to the hydraulic system unless the machine and/or the attachment is lowered to the ground or the safety lock(s) is in the engaged position.
  12. Use of the flashing lights is highly recommended when operating on a public road.
  13. When transporting on a road or highway, use accessory lights and devices for adequate warning to the operators of other vehicles. In this regard, check local government regulations. Various safety lights and devices are available from your NEW HOLLAND CONSTRUCTION dealer.
  14. Practice safety 365 days a year.
  15. Keep all your equipment in safe operating condition.
  16. Keep all guards and safety devices in place.
  17. Always set the parking brake, shut off the engine and remove the key, engage the transmission gears, wait for all machine or attachment motion to come to a stop, before leaving the operators platform to service the machine and attachment.
  18. Remember: A careful operator is the best insurance against an accident.
  19. Extreme care should be taken in keeping hands and clothing away from moving parts.

Ecology and the environment

Soil, air, and water quality is important for all industries and life in general. When legislation does not yet rule the treatment of some of the substances that advanced technology requires, sound judgment should govern the use and disposal of products of a chemical and petrochemical nature.
Familiarize yourself with the relative legislation applicable to your country, and make sure that you understand this legislation. Where no legislation exists, obtain information from suppliers of oils, filters, batteries, fuels, anti-freeze, cleaning agents, etc., with regard to the effect of these substances on man and nature and how to safely store, use, and dispose of these substances.

Helpful hints

  • Avoid the use of cans or other inappropriate pressurized fuel delivery systems to fill tanks. Such delivery systems may cause considerable spillage.
  • In general, avoid skin contact with all fuels, oils, acids, solvents, etc. Most of these products contain substances that may be harmful to your health.
  • Modern oils contain additives. Do not burn contaminated fuels and or waste oils in ordinary heating systems.
  • Avoid spillage when you drain fluids such as used engine coolant mixtures, engine oil, hydraulic fluid, brake fluid, etc. Do not mix drained brake fluids or fuels with lubricants. Store all drained fluids safely until you can dispose of the fluids in a proper way that complies with all local legislation and available resources.
  • Do not allow coolant mixtures to get into the soil. Collect and dispose of coolant mixtures properly.
  • The air-conditioning system contains gases that should not be released into the atmosphere. Consult an air-conditioning specialist or use a special extractor to recharge the system properly.
  • Repair any leaks or defects in the engine cooling system or hydraulic system immediately.
  • Do not increase the pressure in a pressurized circuit as this may lead to a component failure.
  • Protect hoses during welding. Penetrating weld splatter may burn a hole or weaken hoses, allowing the loss of oils, coolant, etc.
