|
(CAT® Yellow) Description of parts. |
|
(Yellow) Components placed aside for access, but not removed. Highlighted areas of adjustment, inspection, or special attention. |
|
(Cyan) Special tools or other equipment required for use in a particular step. |
|
(Light Gray) Components used for reference. |
|
(Magenta) Any fastener, retainer, or electrical connector used to install or remove the primary component. |
Graphic Symbol Description
|

Safety Section
 |
|
Do not attempt to assemble this machine until you read and you understand the assembly instructions. Improper assembly procedures could result in injury or death. |
|
|
Accidental engine starting can cause injury or death to personnel working on the equipment. To avoid accidental engine starting, disconnect the battery cable from the negative (−) battery terminal. Completely tape all metal surfaces of the disconnected battery cable end in order to prevent contact with other metal surfaces which could activate the engine electrical system. Place a Do Not Operate tag at the Start/Stop switch location to inform personnel that the equipment is being worked on. |
|
|
Personal injury or death can result from fumes, gases, and ultraviolet rays from the weld arc. Welding can cause fumes, burn skin, and produce ultraviolet rays. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both to keep fumes and gases from your breathing area. Wear eye, ear, and body protection before working. Protect yourself and others by reading and understanding this warning. Fumes and gases can be dangerous to your health. Ultraviolet rays from the weld arc can injure eyes and burn skin. Electric shock can cause death. Read and understand the instructions of the manufacturer and the safety practices of your employer. Do not touch live electrical parts. See “American National Standard Z49.1, Safety in Welding and Cutting” which is published by the American Welding Society. American Welding Society8669 NW 36 Street #130 Miami, Florida 33166-6672 1-800-443-9353 See “OSHA Safety and Health Standards, 29 CFR 1910” which is available from the U.S. Department of Labor.

|
|
Applying heat to a tank which has held flammable liquids, even when empty, can result in residual flammable liquid or vapor igniting with explosive force. Personal injury or death can result from an explosion. Do not weld or flame cut on any tank that has held flammable liquid without taking the proper precautions such as filling the tank with either inert gas or water. |
|
|
Before any burning or welding on a machine, all electrical power must be disconnected at the source, and locked out/tagged out. Failure to do so may result in electrical component damage. The immediate area shall be rockdusted, and the required fire-fighting materials shall be immediately available. All required gas testing shall be conducted throughout the operation. |
| NOTICE |
|---|
|
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting, and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids. Refer to Special Publication, NENG2500, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products. Dispose of all fluids according to local regulations and mandates. |
| NOTICE |
|---|
|
The fuel tank and/or hydraulic tank must be drained of all fuel and/or oil so that there is no residual fuel and/or oil left in the tank. |
