Introduction
This Special Instruction outlines the details for rerouting the pre-heater exhaust tube. The new rework helps keep debris from damaging the pipe insulation and keeps debris off the hot exhaust.
Do not perform any procedure in this Special Instruction until you have read the information and you understand the information.
Safety Section
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. |
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. |
