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 stand-by mode as directed in the following discussion.
About Stand-By Mode
The lifter's vacuum control valve features a neutral position that reduces the amount of time
required for the lifter to attach to a load and obtain full vacuum. 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 on
the vacuum lift light before the lifter is applied to another load.
WARNING: Never move valve lever to center position while lifter is supporting
load.
Stand-by 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.

Place the power switch in the OFF ( ) position.
CAUTION: Do not set the lifter against any surfaces which could soil or damage the
vacuum pads.
If the lifter is transported to another location, use the original shipping container and secure the
lifter so as to protect the vacuum pads and all other components from damage while in transit.
Storing the Lifter
Use the covers supplied to keep the vacuum pads clean.
!!-CE-!! In accordance with CE Standard EN 13155, the lifter is designed to rest on relatively
horizontal surfaces without tipping over. To store the lifter in this way, set the lifter with the
pads facing downward on a clean, smooth, flat surface and place a support under the control
handle.
