  • Page 12: Safety Rules

    INTRODUCTION Safety rules General safety rules Use caution when you operate the machine on slopes. Raised equipment, full tanks and other loads will change the center of gravity of the machine. The machine can tip or roll over when near ditches and embankments or uneven surfaces.
  • Page 13 INTRODUCTION Operate controls only when seated in the operator’s seat, except for those controls expressly intended for use from other locations. Before you leave the machine: Park the machine on a firm, level surface. Lower the loader arms and attachments to the ground. Place all controls in the neutral position.
  • Page 14 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 the equipment is securely supported. Jack or lift the machine only at jack or lift points indicated in this manual. Incorrect towing procedures can cause accidents.
  • Page 15 INTRODUCTION Pull over to allow faster traffic to pass. Fire and explosion prevention Fuel or oil that is leaked or spilled on hot surfaces or electrical components can cause a fire. Crop materials, trash, debris, bird nests, or flammable material can ignite on hot surfaces. Always have a fire extinguisher on or near the machine.
  • Page 16 INTRODUCTION Your machine is equipped with an operator presence system to prevent the use of some features while the operator is not in the operator’s seat. Never disconnect or bypass the operator presence system. If the operator presence system is inoperable, then it must be repaired. Follow the test procedure ( Joystick and Electro-Hydraulic (EH) control - Check loader arm and bucket hydraulic interlock (55.512)).
  • Page 17 INTRODUCTION • The mounting or suspension for the protective structure, operator’s seat and suspension, seat belts and mounting components, and wiring within the operator’s protective system MUST be carefully inspected for damage. • All damaged parts MUST BE REPLACED. DO NOT WELD, DRILL HOLES, ATTEMPT TO STRAIGHTEN, OR REPAIR THE PROTECTIVE STRUCTURE. MOD- IFICATION IN ANY WAY CAN REDUCE THE STRUCTURAL INTEGRITY OF THE STRUCTURE, WHICH COULD CAUSE DEATH OR SERIOUS INJURY IN THE EVENT OF FIRE, TIP OVER, ROLL OVER, COLLISION, OR ACCI- DENT.
  • Page 18 INTRODUCTION Do not leave equipment in raised position while parked or during service, unless securely supported. Hydraulic cylin- ders must be mechanically locked or supported if they are left in a raised position for service or access. Loader buckets, forks, etc. or other lifting, handling, or digging equipment and its load will change the center of gravity of the machine.

  • Page 26: Torque - Standard Torque Data For Hydraulic Connections

    • Hydraulic connections require a minimum assembly torque in order to provide zero leakage at rated pressure with adequate fatigue resistance. Over-torquing of a hydraulic connection can also lead to leakage or failure. For some connections, NEW HOLLAND CONSTRUCTION requires a different torque value than is listed in the ISO and SAE standards.
