Generic Installation of the WAVS Cleaning System{7348} Caterpillar

Caterpillar Products: All

Introduction

This Special Instruction addresses the procedure for installation of the camera wash system for the WAVS Camera.

Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The safety information in this document and the safety information on the machine are not all inclusive. You must determine that the tools, procedures, work methods, and operating techniques are safe. You must determine that the operation, lubrication, maintenance, and repair procedures will not damage the machine. Also, you must determine that the operation, lubrication, maintenance, and repair procedures will not make the machine unsafe.

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 kill. Read and understand the manufacturer's instruction and your employer's safety practices. Keep your head out of the fumes. Use ventilation, exhaust at the arc, or both, to keep fumes and gases from your breathing zone and the general area. Wear correct eye, ear and body protection. Do not touch live electric parts. Refer to the American National Standard Z49.1, "Safety in Welding and Cutting" published by the American Welding Society, 2501 N.W. 7th Street, Miami, Florida 33125: OSHA Safety and Health Standards, 29 CFR 1910, available from U.S. Dept. of Labor, Washington D.C. 20210.

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 for breathing protection.

Proper Welding Procedure on Machines and Engines with Electronic Controls

Proper precautions are necessary 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.

2. 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.

3. 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. This will reduce the chance of damage from welding current to the components that follow: bearings, hydraulic components and 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.

4. Protect the wiring harnesses from the weld splatter.

Installation Procedure

1. Identify a location for installation of the bottle. Ensure that the location for installation is protected. Ensure that the location of the bottle is lower than the nozzle.

   Follow the steps that are listed below in order to install the bottle.

   1. Locate the nozzle in a horizontal position less than 3.0m (10 ft) away from the bottle.

   2. Locate the bottle no lower than 1.5 m (5 ft) from the nozzle.

2. Inspect the location for the installation and ensure that welding in the location will not damage any of the nearby components.

   1. For optimal performance install the nozzle within 25 mm (1 inch) of the camera lens.

      Note: When installing the nozzle ensure that the nozzle is not viewable in the camera image.

   2. The nozzle needs to be angled at 45 degrees from the surface of the lens.

Check Valve

11. Route the fluid line from the pump to the nozzle. Cut the fluid line and install the check valve no more than 304 mm (1 ft) away from the tank. Ensure that the arrow on the check valve is pointed away from the pump.

    Note: You must prime the pump before installing the check valve. In order to prime the pump allow the water to flow out of the line in order to purge the air out of the line.

12. Check the operation of the system.
