Safety

------ WARNING! ------

Personal injury or death can result from sudden machine movement.

Sudden movement of the machine can cause injury to persons on or near the machine.

To prevent injury or death, make sure that the area around the machine is clear of personnel and obstructions before operating the machine.

----------------------

------ WARNING! ------

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.

----------------------

------ WARNING! ------

Personal injury or death can result from improper lifting or blocking.

When a hoist or jack is used to lift any part or component, stand clear of the area. Be sure the hoist or jack has the correct capacity to lift a component. Install blocks or stands before performance of any work under a heavy component.

Approximate weights of the components are shown. Clean all surfaces where parts are to be installed.

----------------------


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.


Welding on Electronically Controlled Engines

Proper welding procedures are necessary in order to avoid damage to electronic controls. Perform welding on the engine according to the following procedure.

  1. Set the engine control to the "STOP" mode.

  1. Turn OFF the fuel supply to the engine.

  1. Disconnect the negative terminal from the battery.

  1. Disconnect the engine electronic components from the wiring harnesses: ECM, throttle actuator, actuator for the turbocharger compressor bypass, fuel metering valve and sensors.

  1. Protect the wiring harnesses from welding debris and/or from welding spatter.


    NOTICE

    Do NOT use electrical components (ECM or sensors) or electronic component grounding points for grounding the welder.


  1. Connect the welder ground cable directly to the component that will be welded. Place the clamp close to the weld. Clamp placement is important to reduce the possibility of welding current damage to the engine bearings, electrical components, and other engine components.

  1. Use standard welding procedures to weld the materials together.
