Prevention of the Danger caused by Battery
The electrolyte of the battery includes sulfuric acid, so the inflammable and explosive hydrogen is generated
by the battery. The operation error can cause serious damage or fire hazards, so the following items must be
obeyed:
If the display of the densimeter is black, the electricity must be charged. If the display of the
densimeter is bright, the battery must be changed.
When operating the battery, goggles and rubber sleeves should be worn.
It is prohibited to smoke or use open fire near the battery.
If the sulfuric acid splashes the clothes or the skin, the clothes or the skin must be washed by a large
amount of water.
If the sulfuric acid enters into the eyes, the eyes must be washed by a large amount of water, and the
injured must go to hospital.
During the battery operation, the battery maybe generates sparks, and the key switch must be turned to the
‘close’ position. The operations must be carried out according to the following steps:
Do not make tools or other metal objects contact between the battery terminals. Do not let tools or
other metal objects drop around the battery.
When the battery is disassembled, the negative terminals (grounding side) must be disconnected at
first. When the battery is installed, the positive terminals must be connected at first, and then, the
positive terminals are connected to the ground.
At the time of charging the battery, the inflammable and explosive hydrogen is generated. Before
charging, the battery must be disassembled from the machine and put to a drafty place.
The battery should be firmly installed to the original position.
