Attachment Never let anyone ride on any work attachment, such as bucket, crusher, grapple, or clamshell (grab bucket). This creates a falling and crushing hazard, and can result in death or serious injury. The clamshell, grapple, or magnet can swing in all directions. Move work levers (joysticks) in a continuous motion. Failure to move work levers (joysticks) in a continuous motion can cause clamshell, grapple, or magnet to swing into cabin or into a person in work area. This can result in death or serious injury. When using a fork or grapple, do not attempt to pick up an object with its tips. This could damage the machine or cause personal injury, if picked-up object slips off attachment.
ARO1310L Figure 34 Do not use impact force of work equipment for demolition work. This could damage work equipment, cause broken materials to fly off or tipping. This could result in death or serious injury. Do not use work equipment or swing mechanism to pull load in any direction. This could cause the work equipment to move suddenly if the load releases and can result in death or serious injury. Equipment Lowering with Engine Stopped Before lowering any equipment with the engine stopped, clear the area around the equipment of all personnel and bystanders. The procedure to use will vary with the type of equipment to be lowered.
Keep in mind most systems use a high-pressure fluid or air to raise or lower equipment. The procedure will cause high-pressure air, or hydraulic pressure, or some other media to be released in order to lower the equipment. Wear appropriate personal protective equipment and follow the established procedure in the Operation and Maintenance Manual “Equipment Lowering with Engine Stopped” on page 3-74 in the Operation Section of the manual. Engine Stop Turn engine starter switch to "O" (OFF) position and remove engine starter switch key. Before lowering any equipment with engine stopped, clear area around equipment of all personnel and bystanders.
This procedure will cause high-pressure air or hydraulic pressure to be released to lower equipment. Do not stop engine immediately after the machine has been operated under load. This can cause overheating and accelerated wear of engine components. After the machine is parked, allow engine to run for five minutes before stopping the engine. This allows hot areas of engine to cool gradually. Do not leave operator's seat when there is a raised load. DX225LC-3 Safety 1-44
