WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, move the lever on the vacuum control valve to the
"RELEASE" position: Pull upward on the lever's knob, move the lever all the way
back
(towards
operator) and then release it. This forces air into the vacuum pads, quickly breaking the vacuum
seal. After the pads have disengaged completely from the load, move the lifter away. Then
place the lifter in energy conservation mode as directed in the following discussion.
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 upward 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
pumps
before
the lifter is applied to another load. This reduces the amount of battery energy
needed to power the pumps 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.
