WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, the pads can be released either locally (from lifter
location) or remotely (from vacuum package location).
Releasing the pads locally
Move the lever on the vacuum control valve to the "RELEASE" position: Pull outward on the
lever's knob, move the lever all the way downward and then release it. After the pads have
disengaged completely from the load, place the lifter in energy conservation mode as directed in
the discussion to follow.
Releasing the pads remotely
Pinch the release lever against the vacuum package
valve handle, and push the handle inward to the
“RELEASE” position until the vacuum pads disengage
completely from the load. This turns off the vacuum
package, leaving the lifter ready to repeat the
preceding steps, starting with T

About Energy Conservation Mode
The lifter's vacuum control valve features a neutral position, designed to conserve battery energy
between lifts. To utilize this feature, pull outward on the lever's knob, move the lever to the
center position and then release it. Placing the valve lever in the center position closes off the
vacuum line that connects the vacuum pads to the vacuum generating system. As a result,
sufficient vacuum builds up in the line to turn off the low vacuum warning light and the vacuum
pump
before the lifter is applied to another load. This reduces the amount of battery energy
needed to power the pump and warning light.
WARNING: Never move valve lever to center position while lifter is supporting
load.
Energy conservation mode may only be used when the lifter is not supporting a load. The
operator must never move the valve lever to the center position while the lifter is supporting a
load, because this could result in a load release and possible injury to the operator.
