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

ECHARGE

 to follow).

11

  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. 

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 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. 

                                        

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.
