Introduction

This Special Instruction will give the procedure for placing the hydraulic oil cooler onto the front of the machine. It will be easier to clean the hydraulic oil cooler.

Welding Preparation

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

Personal injury can result from working with cleaning solvent.

Because of the volatile nature of many cleaning solvents, extreme caution must be exercised when using them. If unsure about a particular cleaning fluid, refer to the manufacturer's instructions and directions.

Always wear protective clothing and eye protection when working with cleaning solvents.

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

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

Personal injury can result from flame cutting or welding on painted areas.

The effect of gasses from burned paint is a hazard to the person doing the cutting or welding.

Do not flame cut or weld on painted areas.

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

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

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; read and understand 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 manufacturer's instructions and your employer's safety practices. Do not touch live electrical parts.

See "American National Standard Z49.1, Safety in Welding and Cutting" published by the American Welding Society.

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

Note: Personal breathing protection should be worn by the personnel that are welding. Personal breathing protection will prevent fumes from entering the lungs of the person that is welding. Use a 1U-8088 Type H Respirator Gp for breathing protection.

Note: Refer to Service Magazine, SEPD0025 July, "Welding on Fuel and Hydraulic Tanks".

Clean the area in order to be welded. Clean the area of the substances that follow:

  • Oil

  • Grease

  • Paint

  • Dirt

The tank must be at a minimum temperature of 16° C (60° F) before welding and during welding.

Note: Heat distortion of the base metal is possible when you weld. Avoid excessive heating of the base metal.

Attach the welding ground cable directly to the base metal. Protect machined surfaces from the sparks. Protect machined surfaces from the weld splatter.

Proper Welding Procedure on Machines and Engines with Electronic Controls

Proper precautions are necessary in order to prevent damage to electronic controls. When you weld on a machine with electronic controls, use the steps that follow:

  1. Turn off the engine. Put the key start switch in the OFF position.

  1. If the machine has a battery disconnect switch, open the switch. If the machine does not have a battery disconnect switch, disconnect the negative battery cable at the battery.

  1. Connect the ground cable for the welder directly to the actual machine component that will be welded. Attach the clamp for the ground cable as close as possible to the area that is being welded.

    Follow the procedure that is listed above in order to prevent damage from the welding current to the components that follow:

    • Bearings

    • Hydraulic components

    • Electrical components

    Note: Do not use electrical components as a ground point for the welder. Do not use ground points for electronic components as a ground point for the welder.

  1. Protect wiring harnesses from the sparks. Protect wiring harnesses from the weld splatter.
