Powering up the Lifter
Place the lifter's power switch in the “on” position ( ).
6
The blue power 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 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,
press the transmitter power ( Ф ) as shown and hold it
briefly to activate the radio transmitter.
7
Note: If the transmitter is activated, the transmission indicator
light flashes green when any button on the transmitter is
pressed and held; if the transmitter is not activated, the
indicator light flashes red (see B

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 to within 2" [5
cm] of the load center, since off-center loading can cause the load to rotate unexpectedly (see
T
O
R

to follow) and possibly damage the lifter.
8
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 position the lifter so that all pads are in contact with the load.
6
When the operator powers up the lifter, either the stand-by function or the “attach” function is automatically activated,
depending on which was used last. If a 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).
7
The radio transmitter turns off automatically, after a period of inactivity. The operator can also operate the lifter without using
the radio transmitter, if desired.
8
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, if
the operator can maintain control of the load at all times
and
the load weight is low enough to avoid damaging the lifter.
