Komatsu — 8.2 DURING MAINTENANCE

WARNING: Failure to follow these safety precautions may lead to a serious accident. SAFETY When working with hammers, wear protective glasses, helmet, and other protective clothing. Put a brass rod between the hammer and the object when hitting with the hammer. If hard metal parts such as pins, edges, teeth, and bearings are hit with a hammer, there is danger that small pieces will fly off and get into your eyes. Welding operations must always be carried out by a qualified welder and in a place equipped with a proper equipment. Gas is generated, and there is danger of fire or electrocution when carrying out welding, so never allow any unqualified personnel to carry out welding.

The qualified welder must follow the precautions given below. Disconnect the battery terminals to prevent explosion of the battery. Remove the paint from the place being welded to prevent gas from being generated. If hydraulic equipment or piping, or places close to these are heated, flammable vapor or spray will be generated, and there is danger of this catching fire, so avoid applying heat to such places. If heat is applied directly to rubber hoses or piping under pressure, they may suddenly burst, so cover them with fireproof sheeting. Always wear protective clothing. Ensure that there is good ventilation.

Clear up any flammable materials, and make sure that there is a fire extinguisher at the workplace. When repairing the electrical system or when carrying out electrical welding, remove the negative If any abnormality is found during inspection, always carry out repairs. In particular, if the machine is used when there is any abnormality in the brakes or work equipment systems, it may lead to serious accident. Depending on the type of failure, please contact your distributor for repairs. WA380-3MC 1-25 PRECAUTIONS WHEN USING HAMMER REPAIR WELDING PRECAUTIONS WITH BATTERY WHEN ABNORMALITY IS LOCATED
