2.3 Precautions for operation Safety 2.3.4 Battery Battery hazard prevention Battery electrolyte contains sulphuric acid, and batteries gener- ate flammable hydrogen gas, which may explode. Mistaken han- dling can lead to serious injury or fire. For this reason, always observe the following precautions. z Do not use or charge the battery if the battery electrolyte level is below the LOWER LEVEL line. This may cause an explosion. Always check the battery electrolyte level periodi- cally and add distilled water to bring the electrolyte level to the UPPER LEVEL line. z When working with batteries, always wear safety glasses and rubber gloves. z Never smoke or use any flame near the battery.
z If you spill acid on your clothes or skin, immediately flush the area with large amount of water. z If acid gets into your eyes, flush them immediately with large amount of water and seek medical attention. z Before working with batteries, turn the starting switch to the OFF position. As there is a hazard that sparks will be generated, always do as follows. GK032067 z Do not let tools or other metal objects make any contact between the battery terminals. Do not leave tools or other metal objects lying around near the battery.
z Always disconnect the negative (-) terminal (ground side) first when removing the battery; when installing the battery, connect the positive (+) terminal first, and connect the ground last. z Attach the battery terminal securely. GK032068 z Flammable hydrogen gas is generated when the battery is charged, so remove the battery from the chassis, take it to a well-ventilated place, and remove the battery caps before charging it. z Tighten the battery caps securely. z Install the battery securely to the determined place. 2-26 WA150-5H – VEAM934100
