Safety 2.1. General safety measures 2.1.14. Attachments Prior to assembly and operation of an additional attachment, read the attachment's manual and strictly adhere to the instructions on assembly and operation. Do not use attachments that have not been approved of by Komatsu or the responsible Komatsu dealer. If you use attachments which have not been approved of, safety, correct operation, and service life of the machine may be impaired. Komatsu are not liable for injuries, accidents, and damage resulting from the use of attachments that have not been approved. 2.1.15. Battery The batteries are filled with sulphuric acid (battery acid). Always wear safety goggles when handling batteries.
Contact of battery acid with eyes can cause blindness. If acid should get into your eyes, immediately rinse your eyes with ample water and call for medical help. Rinse your eyes with water until a doctor arrives or you are able to visit an ophthalmologist or go to a hospital. Sulphuric acid that gets into contact with skin or clothing may cause acid burns. Immediately rinse the area that has come into contact with the acid with ample water. When working in the area of the battery, your hands may unintentionally get in touch with acid. For this reason, do not touch your eyes while working in the area of the battery. Always wash your hands after work. Batteries produce detonating gas.
Detonating gas is extremely explosive and may be ignited even by the smallest spark. Do not disconnect the battery while the engine is still running. Prior to start of work on batteries, set the start switch to '0'. Set the main switch of the battery (if installed) to 'Off'. Avoid any short-circuits via the poles or the pole terminals of the battery due to unintentional touching with metal objects, such as tools. When removing or inserting the battery, note which of the poles is the positive (+) and which is the negative (-) one. Always disconnect the mass cable first and reconnect it last. Tightly fasten the pole terminals. Loose pole terminals may produce sparks and thus cause explosions.
Ensure that the cover of the positive pole (+) is always mounted. Tighten the cover caps. When repairing the electrical system or performing electric welding, disconnect the negative (-) pole terminal from the battery to interrupt the electric circuit. WA100M-5 – VEAM280201 2-7
