The lifter is equipped with a battery gauge to help the operator evaluate
whether the battery has adequate energy for lifting. 11 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
do not use the lifter if battery energy is lower than 50% of
capacity (that is, when only red lights are illuminated). Correct any
deficiency in the battery or charging system (e.g., forklift alternator) and retest before using the
lifter.
12
WARNING: Never use lifter if battery energy is lower than 50% of capacity.
When the power switch is in the ON ( ) position and the apply/release switch is in the neutral
(center) position, the operator must press the battery test button for a few moments to make the
energy level register on the battery gauge. This enables the operator to check the battery
energy while the lifter is powered up but
not attached to a load.
When the power switch is in the ON ( ) position and the apply/release switch is in the
“APPLY” (right) position, the battery gauge automatically monitors the energy level of the
battery. This enables the operator to check the battery energy while the lifter is powered up and
attached to a load. However, the battery gauge shuts off temporarily while the 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.
Note: If the energy level registers higher than 100% on the battery gauge, the battery has a
“surface charge”. After the pump runs for approximately one minute, the surface charge
dissipates, allowing the operator to take an accurate energy reading.
11
The battery gauge is designed for use with lead acid batteries; readings may not be reliable for other types of batteries.
12
For batteries that are not connected to an automatic charging system, check the battery energy before every lift, and also at
the end of each day's use, to determine whether an overnight charge is needed. 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. Charge the battery as soon as possible after any extended use of the lifter, or whenever the energy is likely to fall
below 20% of capacity during the next period of use. Note: Place the power switch in the OFF position before connecting the
battery to a charger. Operating the vacuum package while the charger is connected to an AC power source could result in
permanent damage to the charger.
