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

M
AINTENANCE
).
Center the lifter’s pad frame to within 2" [5 cm] of the load center, since off-center loading can
cause the load to rotate or tilt unexpectedly (see T

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.
Powering up the Lifter
Place the lifter's power switch in the ON ( ) position.
9
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 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, press the transmitter power/enable button
and hold it briefly to activate the radio transmitter.
10
This button is also used to activate the
enable function (see T

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

Sealing the Pads against the Load
Firm pressure at the center of the lifter helps the vacuum pads begin to seal against the load.
Press an apply button on the lifter or the optional radio transmitter to make sure the apply
function is activated. This energizes the vacuum pump, causing air to be drawn at the pads
immediately. The low vacuum warning buzzer also sounds an alarm until the lifter attains
sufficient vacuum to lift the maximum load weight (see T
O
L
IFT AND
M
OVE THE
L
OAD
: Interpreting
the Warning Buzzer and Lift Light to follow). The lifter must remain in the apply mode
throughout the entire lift.
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,
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.
9
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.
10
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.
