SAFETY PRECAUTIONS FOR MAINTENANCE WARNING: Failure to follow these safety precautions may lead to a serious accident. 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 vapour or spray will be generated and there is danger of this catching fire. 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 fire- proof 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. BATTERY PRECAUTIONS When repairing the electrical system or when carrying out electri- cal welding, remove the negative (-) terminal of the battery to stop the flow of current. Battery handling see “IF BATTERY IS DISCHARGED” on page 161. WHEN AN ABNORMALITY IS FOUND 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 Komatsu distributor for repairs. 47 A0055170
