Unless specified elsewhere in this
INSTRUCTIONS manual, the lifter does not require
maintenance on a routine basis. Instead, maintenance must be performed whenever a
deficiency is indicated by routine inspections or tests. Any maintenance warranted must be
performed before resuming normal operation of the lifter.

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.
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
ATTERY
R
ECHARGE
to follow).
Never use the lifter when battery
energy registers lower than 50% (that is, when only red lights are illuminated), regardless of the
estimated energy requirement.
WARNING: Never use lifter if battery energy is lower than 50% of capacity.
While the lifter's power switch is in the “on” ( ) position, the battery gauge automatically
monitors battery energy (provided that the lifter is not in stand-by mode). However, the battery
gauge shuts off temporarily while the vacuum pumps are 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 lifter's power switch is in the “off” ( ) position (or the lifter is in stand-by mode), 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 pumps runs for
approximately one minute, 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.
