UniCarriers FD160-2 Operation & Maintenance Manual page 42

INSPECTION AND SERVICE
• When charging the battery, follow the instructions in the
Instruction Manual of the 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
1-37
• 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.
• Static electricity from the body
Before checking or cleaning the battery, remove static electricity from
your body by touching metallic parts at a place away from the battery.
• Pay attention to battery electrolyte level
Do not operate the truck or charge the battery when the
battery electrolyte level is below the LOWER LEVEL marking;
otherwise, the components inside the battery may be
deteriorated and the battery life shortened, and in the worst
case an explosion might occur. Keep the battery electrolyte
level between the UPPER LEVEL and LOWER LEVEL
markings at all times. Add purified water if the level is low.
• Do not connect or disconnect the battery receptacles with
the battery circuit conducting Electric trucks
• Prohibit to connect the battery that has over the specified
voltage.
• When connecting the booster cable to the battery, pay
attention to the polarity of the pole.
Two batteries shall be connected in parallel, not in series.
