ASSEMBLY
TO SET UP THE LIFTER
1) Open the shipping container and remove all materials for restraining or protecting the vacuum
lifter during shipping. Save the container for use whenever the lifter is transported.
2) Position the adjustable lift point tube as follows: The location of the lift point can be adjusted
to obtain the optimal hang angle of the lifter and load. A different hang angle may be
desirable, depending on the angle needed to attach the lifter to the load, release the load or
manipulate the load during a lift.
First disengage the lifter’s tilt latches (see OPERATION: TO TILT THE LOAD: Operating the Tilt
Latches) and raise the lift bar to a vertical orientation. Make sure the lift bar latches in
the vertical orientation before releasing the lift bar.
To adjust the lift point location, remove both retaining bolts and associated hardware, and
reposition the adjustable lift point tube as desired. Reinstall the retaining bolts and hardware,
making sure to secure them tightly in position as originally installed.
WARNING: Lift point must be adjusted so as to prevent interference between
adjustable lift point tube and load.
Note: If the load would extend higher than the lift point when lifted or tilted upright (see
OPERATION: TO TILT THE LOAD), the lift point must be adjusted to prevent interference
between the adjustable lift point tube and the load. Failure to do so may damage the lifter or
load, and may result in the release of the load.
3) 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).
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift bail from slipping off under any circumstances.
Attach the hoisting equipment hook to the lift bail, and use the hoisting equipment to raise
the lifter out of the shipping container. Be careful to avoid damaging any vacuum pads.
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.

4) Install the movable control pendant by inserting the plug of the coiled cord into the controls
receptacle on the power system enclosure. Then secure the connector by tightening its
threaded collar.
5) Assemble the pad frame in the configuration that will provide optimal support of the load
while lifting (see TO CHANGE THE PAD FRAME CONFIGURATION to follow).
6) Open the power system enclosure and connect the electrical connectors uniting the battery to
the battery charger and the vacuum generating system. Now the lifter is operational.
7) Perform Operational and Load Tests for the lifter as directed in MAINTENANCE: TESTING
SCHEDULE.
TO CHANGE THE PAD FRAME CONFIGURATION
This lifter offers a variety of pad frame configurations to accommodate different load dimensions
and weights (see illustrations on following page). Configurations are created by positioning,
rotating or removing the pad mounts, and/or by installing or removing pad frame extensions.
Always arrange the vacuum pads in a symmetrical configuration, in both width and length
dimensions.
CAUTION: Minimum of 2 vacuum pads must be mounted on main pad frame.
To prevent lifter damage and to provide adequate load support, a minimum of 2 activated
vacuum pads must be mounted on the main pad frame, regardless of the configuration selected
(see illustrations on following page). It is especially important to observe this rule when pad
frame extensions are employed: The vacuum pads may not be located solely on the extensions,
as such a configuration may not provide adequate load support and may damage the lifter.
The lifter is equipped with a dual vacuum system, as indicated by color-coded vacuum hoses.
For maximum effectiveness, adjacent vacuum pads must be connected to separate circuits of the
vacuum system in an even distribution. Make sure that an equal number of pads is connected to
the green circuit and to the red circuit.
After changing the pad frame configuration, make sure all vacuum hoses are secure and routed
to avoid being pinched, snagged, abraded or otherwise damaged while the lifter is in operation.
Also be sure to verify that all pads are connected and functioning correctly.

To Install/Remove Pad Frame Extensions
1) Insert the end of a pad frame extension in one socket on the
main pad frame, so that the holes align for the cotterless hitch
pin.
2) Secure the pad frame extension in the pad frame by pushing a
cotterless hitch pin through the holes until the retaining ball
emerges on the far side of the pad frame socket.
3) Use the quick connectors to connect the vacuum hoses from the pad frame extensions to the
main pad frame as directed in the discussion to follow.
3) Repeat steps 1-3 to install the other pad frame extensions as required for the pad frame
configuration desired.
4) To remove the pad frame extensions, reverse this procedure. Store pad frame extensions in
a clean, dry location to protect them from environmental exposure.
To Install/Remove, Rotate and Position Pad Mounts
1) Slide a pad mount over one arm of the pad frame. Note that the orientation of the vacuum
pad can be changed by moving the pad mount to an arm angled in a different direction. This
can be useful in avoiding obstacles or features on the load. Each pad mount can also be
rotated 180° to allow for the best hose routing.
2) Position the pad mount approximately in the desired position and line up one of the locating
holes in the pad mount with a corresponding hole in the pad frame arm. Multiple holes are
provided to accommodate small increments between mounting locations.
3) Use the quick connector to connect the vacuum hose from the vacuum pad to the appropriate
circuit of the vacuum system as directed in the discussion to follow.
4) Repeat steps 1-3 to install and position each vacuum pad as required for the pad frame
configuration desired.
5) To remove the pad mounts, reverse this procedure. Store pad mounts in a clean, dry location
to protect them from environmental exposure.
To Connect/Disconnect Vacuum Hoses
The vacuum hose for each vacuum pad is connected to or
disconnected from the vacuum system by means of a quick
connector. To connect the vacuum hose, push the male and
female ends of the connector together until they lock. To
disconnect the vacuum hose, move the release ring on the
female end away from the male end until the connector
separates.
Note: For proper function of the dual vacuum system, make sure
that vacuum pads are connected to alternating circuits of the
vacuum system (red or green).
Note: Whenever a quick connector is disconnected, the corresponding vacuum pad does not
contribute to the load capacity, whether or not the pad is mounted on the pad frame.

INTENDED USE
LOAD CHARACTERISTICS
WARNING: This lifter is NOT intended for lifting hazardous materials, such as
explosives or radioactive substances.
The operator must verify that the lifter is intended to handle each load, in accordance with the
following requirements:
• The load must not exceed the maximum allowable weight specified under Load Capacity (see
SPECIFICATIONS).
• The load must be a single piece of nonporous or semiporous material with a flat and relatively
smooth contact surface. Lifters equipped with foam vacuum inserts are able to accommodate
surface relief up to 3/8" [9.5 mm], provided contour changes are not too abrupt. To
determine whether the load is too porous, rough or contoured to seal adequately, perform the
test under Vacuum Level on Other Surfaces (see OPERATION: TO APPLY THE PADS TO A LOAD).
• The load's contact surface must be suitable for obtaining a friction coefficient of 1 with the
lifter's vacuum pads (see MAINTENANCE: VACUUM PAD MAINTENANCE: Friction Coefficient), as
verified by a friction test. If necessary, contact Wood's Powr-Grip for help in conducting a
friction test.
•While the minimum length and width of the load are determined by the Pad Spread (see
SPECIFICATIONS), the maximum length and width are determined by the allowable
overhang, or the amount of load material that can extend sideways beyond the vacuum pads
without breaking or otherwise being damaged.
The allowable overhang depends on the kind of load material being lifted, the thickness of the
material, and the angle at which it is handled (if any). Since materials such as glass, stone or
sheet metal each have different physical properties, the allowable overhang must be
evaluated separately for each type of load. If necessary, contact Wood’s Powr-Grip or an
authorized dealer for help in determining the recommended overhang in a specific situation.
• 8" [20 cm] is the maximum allowable thickness of loads at the maximum weight (see
SPECIFICATIONS: Load Capacity). However, allowable thickness increases as load weight
decreases. If necessary, contact Wood’s Powr-Grip for help in determining the maximum
thickness permitted when handling any specific load.
Note: Vacuum pads can stain or deform load surfaces with light colors or soft coatings. The
operator should test such surfaces for detrimental effects before using the lifter on them.
OPERATING ENVIRONMENT
The operator must determine whether the lifter is intended to be used in each work environment,
in accordance with the following restrictions:
WARNING: Never use lifter in dangerous environments.

Rev 0.0/9-10 CLADDING LIFTER ● W/VIFS625 PAD INSERTS #35078:

• This lifter is not intended for use in any environment that is inherently dangerous to the
operator or likely to compromise the lifter's ability to function. Environments containing
explosives, caustic chemicals and other dangerous substances must be avoided when using
the lifter.
• The lifter's work environment is limited by the Operating Elevation and Operating Temperatures
indicated in SPECIFICATIONS.
• Using the lifter in wet environments may require the operator to take special precautions:
Moisture on contact surfaces of the load or vacuum pads diminishes the lifter’s slip resistance,
thereby reducing the lifting capacity (see MAINTENANCE: VACUUM PAD MAINTENANCE: Friction
Coefficient).
WARNING: Moisture reduces slip resistance of vacuum pads.
Although the lifter's exterior surfaces can tolerate some exposure to water vapor, they are not
designed to be water-tight. Submerging the lifter or using it in rain may damage lifter
components; these and similar conditions must be avoided.
TYPICAL APPLICATIONS
Though the lifter is designed with the
flexibility to be used in many different
ways, the following illustrations
represent some typical applications.
