Know the maximum height and the maximum reach of your machine. Serious injury or death by electrocution can occur if the machine or the work tools are not kept a safe distance from electrical power lines. Keep a distance of at least 3000 mm (118 inch) plus an additional 10 mm (0.4 inch) for each 1000 volts over 50000 volts. |
 |
For safety, one of the following may require a greater distance:
- Local codes
- State codes
- Requirements of the job site
| NOTICE |

When swinging into any object, do not use the object to stop the swinging motion. Inspect the machine for damage if the boom is swung into a structure or an object. Repeated stopping of the swing by an object can cause structural damage. With certain boom-stick-work tool combinations, the work tool can hit the cab or front of the machine. Always check for interference when first operating a new work tool. Whenever the wheels of the machine raise off the ground while operating, lower the machine back to the ground smoothly. DO NOT DROP OR CATCH IT WITH THE HYDRAULICS. Damage to the machine can result. |
With certain combinations of work tools, the third pedal can have different functions. Always check the function of the third pedal before you use the third pedal.
Know the location of any power cables and utility mains. Mark the locations clearly before you operate the machine.
Consult your Caterpillar dealer for special work tools that are available for use in various applications.
Move the machine whenever the position for operation is not efficient. The machine can be moved forward or backward during the operating cycle.
Use a comfortable travel speed while you operate the machine.
Operating efficiency can be increased by using more than one machine control to perform a task.
Never swing a load over a truck cab or workers.
Position the truck so that material can be loaded from the rear of the truck or from the side of the truck. Load the truck evenly so that the rear axles are not overloaded.
Select a work tool that is correct for the work to be performed. Work tools that do not match the work slow down the cycle.
Restricted Operation
 | |
| Illustration 1 | g00609664 |
Do not use the swing force to perform the following operations:
- Pushing material
- Separating material
- Demolition
Do not swing the machine while the grapple is in the pile of material.
These operations will damage the boom, the stick and the work tool and the operations will reduce the life of the equipment.
 | |
| Illustration 2 | g00609665 |
Do not use the dropping force of the work tool as a hammer. This will bring excessive force on the rear of the machine. Possible damage to the work tool and/or the machine could result.
 | |
| Illustration 3 | g00609704 |
If the cylinder is operated to the end of the stroke during operations, excessive force will occur on the stopper on the inside of the cylinder. This will reduce the life of the cylinder. To avoid this problem, always leave a small margin of play when the cylinder is operated.
 | |
| Illustration 4 | g00618735 |
While the work tool is in the material pile, do not use the travel force for any movement of the pile. This operation will cause excessive force on the rear of the machine.
 | |
| Illustration 5 | g00618741 |
Do not use the dropping force of the rear of the machine for moving material. This operation will damage the machine.
Operating Precaution
 | |
| Illustration 6 | g00618744 |
When you work over a bank do not lower the boom so the bottom side of the boom touches the ground.
When you work over a bank, do not allow the boom to interfere with the wheels.
