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) 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 bail.
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift bail from slipping off under any circumstances.
Note: Some hoisting equipment hooks could interfere with an upright load that extends
beyond the lifter's pad frame. If the load would contact the hook during lifter operation, the
operator must prevent this by attaching a sling (or other rigging that does not interfere with
the load) between the hook and the lift bail.
WARNING: Any sling used must be rated to carry maximum load weight plus
lifter weight.
Use the hoisting equipment to raise the lifter out of the shipping container. Be careful to
avoid damaging any vacuum pads. Remove the pad covers and save them for use whenever
the lifter is stored.
3) Arrange the pad frame in the configuration that will provide optimal support of the load while
lifting (see T

This lifter offers a variety of pad frame configurations to accommodate different load dimensions
(see SPECIFICATIONS: Pad Spread). Configurations are created by installing or removing the
pad frame’s extension arms and by repositioning the vacuum pads, which have movable mounts.
Select a configuration to provide optimal support across the load surface and to minimize load
overhang. Assemble the pad frame in a symmetrical arrangement, to keep the lifter balanced,
and make sure all vacuum hoses are secure and routed to avoid being pinched, snagged,
abraded or otherwise damaged while the lifter is in operation.
