• If anyone swallowed electrolyte accidentally:
Let him drink a copious amount of water or milk
with egg white and salad oil mixed in it and take
a rest. Send for a doctor.
• Wear safety glasses when handling batteries
Wear rubber gloves, rubber boots, safety glasses
when changing or charging batteries, adding
battery electrolyte, or adjusting the specific
gravity of the battery electrolyte.
• The electric truck's batteries are high voltage
The batteries used for electric trucks are high
voltages more than 48 V. If anyone touches it
inadvertently, he can get an electrical shock
accident or burn.
• No fire
Since explosive hydrogen gases are always
being released from the battery, there is a danger
of causing an explosion. Never smoke or use fire
or naked flame near the battery. No sparks.
To prevent the generation of sparks, turn
off the charger switch before connecting or
disconnecting the battery or charger cable.
• Do not put any metal tool on the battery case
Do not short the battery terminals
•
Do not short the battery terminals by placing a
piece of metal between the positive and negative
terminals. A loose terminal might cause sparks,
causing an explosion. Make sure the terminals
are tight. Use caution not to have the wrong
connections of the battery terminals.
When turning the screw of the positive pole of
•
the battery, use caution not to allow the tool
to touch the metal parts of the truck, such as
the engine Engine-powered trucks
If the tool touches metal parts, there might occur
sparks, causing an accident.

charger
• No fire during charging
Batteries give off hydrogen gases during
charging. No fire. No sparks.
Make sure the battery electrolyte temperature
•
is below 40°C
Hydrogen gases are released from the battery
during charging, causing the battery to heat.
Before trying to charge the battery, make sure the
battery electrolyte temperature is below 40°C.
(If the electrolyte temperature reaches 50°C or
more, discontinue charging and wait until the
electrolyte temperature drops to 40°C or lower.)
• Have a good ventilation when charging
Since hydrogen gases are released from the
battery during charging. Have a good ventilation;
otherwise an explosion might result. Keep the
battery case cover open.
• Do not connect or disconnect the battery
receptacles with the battery circuit conducting
Electric trucks
When cleaning the battery, make sure the
•
battery caps are securely tightened
• Static electricity is hazardous
Static electricity is generated when cleaning the
top surface or connections of the battery with
a dry cloth, or covering the battery with a vinyl
sheet. It might cause an explosion.
