The lifter is equipped with a battery gauge to help the operator evaluate whether
the battery has adequate energy for lifting. Factors such as the condition of
the battery, the time required to execute a lift, and the porosity of the load
combine to determine how much battery energy is needed.
operator's responsibility to evaluate these conditions and to make
sure the battery has sufficient energy to complete a lift safely.
the battery energy before every lift and also at the end of each day's use, to
decide whether a charge is needed (see B
battery energy registers lower than 20%, regardless of the estimated energy requirement.
WARNING: Never use lifter if battery energy is lower than 20% of capacity.
While the valve handle is in the "APPLY" position (power on), the battery gauge automatically
monitors battery energy. However, the battery gauge shuts off temporarily to protect the
circuitry while the vacuum pump is running. When the pumping cycle is completed, the battery
gauge requires a few moments to stabilize before it displays an accurate energy reading again.
While the valve handle is in the "RELEASE" position (power off), the battery energy can be
checked manually using the battery test button. If the lifter has not been used since the battery
was charged, the battery gauge may falsely indicate an energy level that is higher than actual,
due to a "surface charge" on the battery. After the pump runs for approximately one minute, the
surface charge dissipates, allowing the operator to take an accurate energy reading.

ECHARGE
Only use a battery charger supplied by or approved by Wood's Powr-Grip; other chargers may
reduce battery life. Charge the battery as soon as possible after any extended use of the lifter,
or whenever the battery gauge indicates diminished energy (see B
Temperatures above 70° Fahrenheit [21° Celsius] require the battery to be charged more
frequently.
CAUTION: Charge the battery only while the valve handle is in "RELEASE" position
(power OFF).
Operating the lifter when the charger is connected to an AC power source could
result in permanent damage to the charger.
Identify the input voltage marked on the battery charger, and plug it in to an appropriate power

source.
The power source must be equipped with a ground fault circuit interrupter, in order to
reduce the risk of electrical shocks.
WARNING: Power source must be equipped with ground fault circuit interrupter.
Usually a battery takes no more than 16 hours to charge completely, after which the charger
shuts off automatically. Following long-term use, a battery gradually loses capacity. Replace it
whenever the operating time between recharging is no longer satisfactory.
11
The battery charger must be disconnected from its AC power source in order to test the battery energy; otherwise, the energy
reading on the battery gauge would not be accurate.
12
Any external power supply must conform to all applicable local codes.
