1) Open the shipping container and remove all materials for restraining or protecting the vacuum
lifter. Save the container for use whenever the lifter is transported.
2) If necessary, assemble the lifter's lift bar as follows: One segment
of the lift bar can be removed, to reduce overall lifter dimensions
for shipping. If so, orient the removable segment (1) as shown in
the illustration, and slide it over the other segment until the bolt
holes align. Reinstall the bolts and all associated hardware (2);
then tighten both bolts securely.
3) Position the lifter's lift spool as follows: The adjustable lift spool
assembly provides 3 different lift points (see illustration), in order
to optimize the lifter's hang angle and/or its overall height for the
intended use. 5 To change the lift spool position, remove the
retaining bolt (3) and, if necessary, loosen the pivot bolt (4). Next
pivot the lift spool assembly until the bolt holes align for the
desired spool position. Then reinstall the retaining bolt and all
associated hardware. Tighten both bolts securely.
Note: For pad frame configurations that use extension arms (see

spool to avoid contact with the extension arms when the pad frame
is rotating.
4) Suspend the lifter from a crane as follows: Select hoisting equipment (crane and hoist, when
applicable) rated to carry the maximum load weight plus the lifter weight (see
SPECIFICATIONS: Maximum Load Capacity and Lifter Weight).
Note: Any application of the lifter must conform to all statutory or regulatory standards that
relate to the hoisting equipment when used in its geographical location (eg, relevant OSHA
standards in the USA).
Disengage the tilt latch (see OPERATION: T

) and raise the lift bar to a vertical
orientation. Then attach the hoisting equipment hook to the lift spool.
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift spool from slipping off under any circumstances.

When the extension arms are installed on the pad frame (see illustration in OPERATING FEATURES), placing the lift spool in
the lowest position would create interference when the pad frame is rotated. To avoid this problem, place the lift spool in one of
the other two positions or remove the extension arms (see T
O C HANGE THE P AD F RAME C ONFIGURATION to follow).
