Powering up the Lifter
Place the lifter's power switch in the ON ( ) position. 5 The blue indicator light remains
illuminated while the lifter is powered up. Keep the power switch in the ON position while lifting
a load. Any power interruption during a lift could result in the release of a load and possible
injury to the operator or others (see T

WARNING: Never turn power off while lifting.
If the lifter is equipped with a Remote Control System, activate the radio transmitter by turning
the transmitter power/enable switch to the “START” position and then releasing it, allowing it to
return to the “ON” position. 6 This switch also activates the enable function (see A

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:

ACUUM

).
The lifter must be attached only to vertically oriented loads. Center the pad frame to within 2" [5
cm] of the load center, since off-center loading can cause the load to rotate unexpectedly (see

to follow), and it may also damage the lifter. 7 Make sure that all
vacuum pads will fit entirely on the load’s contact surface (see SPECIFICATIONS: 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 all pads are touching the contact surface.
5
When the operator powers up the lifter, either the stand-by function or the apply function is automatically activated, depending
on which was used last. If the vacuum pump or any other powered component fails to function while the lifter's 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).
6
The radio transmitter turns off automatically, after a period of inactivity. The operator can also operate the lifter without using
the transmitter, if desired.
7
The lifter is designed to handle the maximum load weight (see SPECIFICATIONS: Maximum Load Capacity) when the load’s
center of gravity is positioned within 2" [5 cm] of the pad frame’s center point. Occasional loading deviations are permissible,
provided that the operator can maintain control of the load at all times and that the load weight is low enough to avoid damaging
the lifter.
