(1) Precautions when recharging batteries
· Make sure the power cable is securely connected before turning on
the battery charger. Do not disconnect or reconnect the power cable
while the battery charger is on.
· Loosen the cap on each cell in the battery.
· Do not remove the battery receptacle during recharging; otherwise
there is danger of causing sparks.
· Do not try to check the battery voltage by shorting the poles of the
battery.
· The battery must only be recharged in a well-ventilated space, with
no flammable materials in the area.
· Charge batteries on an acid-resistant floor surface that is well
drained, because the battery electrolyte might spill on the floor
during recharging.
· Make sure that the charging equipment is equipped with a ground
fault interrupter. (it must be grounded).
(2) Take the following precautions to prevent accidents such as electric
shocks or shorts when repairing the electrical system on the truck:
· Make sure the power switch is turned off before starting any repairs
or inspections.
(Remove the grounding cable from the battery if the truck does not
have a battery relay.)
· Make sure the cables are not wet or frayed. Avoid using any electric
tool in a wet atmosphere.
· Be careful not to drop a wire, tools or parts inside the truck. If you
drop something, make sure to remove it.
(3) Do not touch any switch which has a warning sign attached to it. Use
special caution if you do need to touch it.
(4) Keep clear of broken wires.
(5) Always attach a sign to the battery charging unit stating “Do not
operate” when the electric system is being repaired.
(6) Write the name, rated voltage, and current of the power supply unit
and the name of the person in charge of the battery charging unit near
the power supply switch.
(7) Only use approved fuses for the power supply switch.
(8) If the battery charging unit fails to operate normally, turn off the
power switch immediately and report to the supervisor.
(9) Do not smoke near the battery. Do not use an open flame to check the
battery electrolyte level. Explosive gases are always being released
from the battery and there is a danger of causing an explosion.
(10) Keep the top surface of the battery case clean. If it is contaminated
with dust or water, there is a danger that an explosion may occur due
to an interfacial discharge occurring between the battery terminal and
the truck frame.
