Powering up the Lifter
Place the power switch in the ON ( ) position (blue indicator light remains illuminated while
power is engaged). The power switch must remain in the ON position while operating the lifter. 3
WARNING: Never turn power off while operating lifter.
Placing the power switch in the OFF ( ) position during lifter operation could result in the
release of the load and possible injury to the operator (see T

Positioning the Lifter on the Load
Make certain that the contact surfaces of the load and all vacuum pads are free of any
contaminates that could prevent the pads from sealing against the load (see MAINTENANCE:
V
ACUUM P AD M AINTENANCE ).
The lifter must be attached only to vertically oriented loads. Center the pad frame from left to
right on the load, and position the uppermost vacuum pads near the top edge. This position will
maximize stability while lifting the load. Make sure that all vacuum pads will fit entirely on the
load’s contact surface (see SPECIFICATIONS: Maximum Pad Spread) and that they will be loaded
evenly while lifting (see SPECIFICATIONS: Per-Pad Load Capacity). Then apply the lifter to the
load so that the pads are touching the contact surface.
Sealing the Pads against the Load
Turn the apply/release switch on the movable control pendant to the “APPLY” position
(clockwise). This engages the vacuum pumps, causing air to be drawn immediately at the
vacuum pads. Press the lifter onto the load until all the pads seal against it. The apply/release
switch must remain in the “APPLY” position throughout the entire lift.
WARNING: Keep apply/release switch in “APPLY” position throughout lift.
Note: If a vacuum pad has been lying against a hard object (as during shipping), it may be
slightly distorted. Although initially it may be difficult to apply the pad to a load, this condition
should correct itself with continued use.
WARNING: Do not disconnect control pendant during lifter operation.
The movable control pendant is not intended to be disconnected during lifter operation.
Disconnecting the control pendant is likely to result in a load release and injury to the operator or
others nearby.

If a vacuum pump or any other powered component fails to function while the power switch is in the ON position, examine
each circuit breaker (adjacent to power switch) to determine whether it has interrupted the electrical circuit to the component.
Although the operator can reset the circuit breaker, the power interruption may indicate an electrical problem that requires
attention. Correct any deficiency before resuming normal operation of the lifter (see wiring diagram provided).
