## [ 1. SAFETY PRECAUTIONS ] ## P. GENERAL GUIDELINES FOR WELDING Welding work must be performed by a certified welder with sufficient experience. In addition, safety practices must be followed by any personnel involved in such work. Identify all cracks to be repaired or areas to be welded by thoroughly cleaning the suspected surface, remove paint, and check with dye penetrant or magnetic particle testing. The life expectancy of the welded area depends on the work quality and the attention given to details during welding. - ・ Turn starter key to "OFF" position. - ・ Remove negative (-) cable from battery terminal to turn off the current. - ・ Attach welder ground cable with 1 m {3.3 ft} from component being welded. If grounding cable is attached near electric parts/connectors, these electric parts/connectors may cause damaging. - ・ Attach welder ground cable near the weld area. Futhermore, the cable attached are is to be positioned at the same welding area. - ・ Make sure that neither bearing nor seal are there between the welder ground and the weld area. - ・ Do not attach the welder ground cable to the near attachment pin and/or cylinder. It causes the damage of plating. - ・ Remove paint from any surface to be welded. Painted surfaces produce unhealthy gasses when welded. - ・ Always wear protective clothing appropriate to the welding, and use protective equipment for the welding job. - ・ Perform work in a well ventilated areas. - ・ Clear the flammable items and provide the fire extinguisher. <!-- image --> ## AVOID FIRE HAZARDS - -Provide a fully charged fire extinguisher at all times while performing grinding, heating, or welding. -Clean oil and/or flammable materials from any surface to be cut. - -Protect all flammable parts and surfaces from sparks and/or flames Perform work in a well ventilated area. - -Keep sparks and flames away from paint and/or solvent. - -Keep away sparks and flames from cylinder rods, seals, electrical wires, and/or hydraulic hoses
