MAINTENANCE AND CHARGE OF BATTERY
1. A Rechargeable Gel battery is used in this lift table.
2. The H-3768 lift tables are equipped with a specific
charger to charge the battery. The charger can be
plugged into a standard 110 volt outlet.
CAUTION! Before connecting the charger to
the socket, make sure the emergency shutoff
switch and key switch are in the OFF position.
Please charge the battery in a dry, well-
ventilated area and away from any source
of fire. If the lift table is not in use, battery
charges should be performed no less than
once every six months.
3. The battery of the lift table should be charged
fully and regularly. When the battery reaches 20%,
please charge the battery immediately.
4. The charger will adjust the current according to
residual capacity of the battery automatically,
which ensures the battery is charged correctly.
After charging the battery, the charger indicates
full capacity and stops automatically. Charging
generally lasts 7-9 hours.
BATTERY INDICATOR
1. BATTERY CAPACITY METER – The charge status of
battery is indicated on battery capacity meter. With
consumption of battery capacity, the gauge will
descend downwards from the top. (See Figure 3)
2. The lift table will automatically cut off lifting functions
when the battery reaches 20%.
