The DC Vacuum Back-Up System 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.

It is the operator’s responsibility to

evaluate these conditions and to make sure the battery has

sufficient energy to complete a lift safely.

Check 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

Do not rely on the

Back-Up System when battery energy registers lower than 50% (that is, when only red lights are
illuminated), regardless of the estimated energy requirement.

WARNING: Never rely on Back-Up System if battery energy is lower than 50% of

capacity.

While the Back-Up System is activated (see OPERATION: To Use the Back-Up System), its battery

gauge automatically monitors the energy level of the Back-Up System's battery. However, the
battery gauge shuts off temporarily while the Back-Up System's vacuum pump is running, to

prevent an inaccurate reading. 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 Back-Up System is

not

activated (see OPERATION: When the Back-Up System is Not in

Use), its battery energy can be checked manually using the battery test button. If the Back-Up
System 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
Back-Up System’s pump runs for approximately one minute (see B

preceding), the surface charge dissipates, allowing the operator to take an accurate energy

reading.

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.
