BATTERY HAZARD PREVENTION

Battery electrolyte contains sulphuric acid, and batteries generate flammable hydrogen gas, which may explode.
Mistaken handling can lead to serious injury or fire. For this reason, always observe the following precautions.
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 periodically and add distilled water to bring the
electrolyte level to the UPPER LEVEL line.
When working with batteries, always wear safety glasses and rubber gloves.
Never smoke or use any flame near the battery.
If you spill acid on your clothes or skin, immediately flush
the area with large amounts of water.
If acid gets into your eyes, flush them immediately with
large quantities of water and seek medical attention.
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.
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.
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. Tighten the battery terminals
securely.
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.
Tighten the battery caps securely.
Install the battery securely to the determined place.
