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

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 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 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.

ECHARGE

CAUTION: Charge battery only while lifter’s power switch is in OFF ( ) position.

Operating the lifter when the battery charger is connected to an AC power source could result in

permanent damage to the charger.
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

ATTERY

T

EST

preceding).

12

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.
