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:

).
Arrange the sliding hand cup mounts to optimize load support and minimize load overhang while
lifting (see INTENDED USE: L
OAD
C
HARACTERISTICS
). Make sure the vacuum pads are positioned at
equal distances from the lift eye. To position a sliding hand cup
mount, remove the cotterless hitch pin from the cup mount by
pulling on the pull ring. Slide the cup mount to the desired
position and align the holes for the cotterless hitch pin. Secure
the cup mount by pushing the cotterless hitch pin through the
holes until the retaining ball emerges on the far side of the cup
mount. Repeat these steps for each cup mount.
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) 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: Pad Spread) and that they will be loaded evenly
while lifting (see SPECIFICATIONS: Per-Pad Load Capacity). In addition, adjacent pads must not
contact one another. Then apply the lifter to the load so that all pads are touching the contact
surface.
Sealing the Pads against the Load
Make certain the entire sealing edge of each vacuum pad is contacting the load surface. Then
pump the plunger of the hand cup until the red line stays hidden, indicating that the pad is
securely attached (see T

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.
