Install the prop for the cab before you work under a raised cab.
Install the tailgate locking pins before entering the area beneath the tailgate.
Unless you are instructed otherwise, never attempt adjustments while the machine is moving or while the engine is running.
Whenever there are equipment linkages, the clearance in the linkage area will change with movement of the equipment.
Stay clear of all rotating parts and all moving parts.
Keep objects away from moving fan blades. The fan blades will throw objects and the fan blades will cut objects.
Do not use a wire cable that is kinked or frayed. Wear gloves when you handle wire cable.
When you strike a retainer pin, the retainer pin might fly out. The flying retainer pin can injure personnel. Make sure that there are no people in the area when you strike a retainer pin. To avoid injury to your eyes, wear protective glasses when you strike a retainer pin.
Chips or other debris may fly off objects when you strike the objects. Make sure that no one will be injured by flying debris before you strike any object.
Be sure that the area behind the machine is clear of personnel before you operate the ejector blade.
Rollover Protective Structure (ROPS) or Falling Object Protective Structure (FOPS)
A ROPS is designed to provide operator crush protection in a rollover.
To avoid the possible weakening of the ROPS or of the FOPS, consult your Caterpillar dealer before you alter the structure. Do not alter the structure by welding on the structure, by cutting the structure, by adding weight to the structure, or by drilling holes in the structure.
Any alteration that is not specifically authorized by Caterpillar invalidates the Caterpillar certification for the ROPS or for the FOPS. The protection that is offered by the ROPS will be impaired if the ROPS has structural damage. Damage to the structure can be caused by an overturn or by falling objects.
Do not mount items (fire extinguishers, first aid kits, work lights, etc) by welding any brackets to the ROPS or by drilling holes in the ROPS. See your Caterpillar dealer for mounting guidelines.
