WARNINGS
Powr-Grip is pleased to offer the most reliable vacuum lifters available.
Despite the high degree of security provided by this product, certain
precautions must be observed to protect the operator and others.
Always
wear personal protective equipment that is appropriate for the material being handled.
Follow trade association guidelines.
Always
operate the lifter under conditions approved for its design (see INTENDED USE:
OPERATING ENVIRONMENT).
Never
operate a lifter that is damaged, malfunctioning, or missing parts.
Never
operate a lifter if the sealing edge of any vacuum pad is cut or otherwise damaged.
Never
remove or obscure warning labels.
Never
operate a lifter if the Load Capacity or any warning appears to be missing or obscured.
Always
make certain the contact surfaces of the load and all vacuum pads are clean prior to
applying the pads (see MAINTENANCE: VACUUM PAD MAINTENANCE).
Never
exceed the Load Capacity or attempt to lift loads the lifter is not designed for (see
INTENDED USE: LOAD CHARACTERISTICS).
Never
attempt to lift cracked or broken glass with this lifter.
Always
position the vacuum pads correctly on the load prior to lifting (see OPERATION: TO APPLY
THE PADS TO A LOAD).
Never
lift a load when any vacuum indicator shows inadequate vacuum.
Never
touch the vacuum release controls during a lift. This may result in loss of vacuum and
release of the load.
Never
allow people to ride on the lifter or the load being lifted.
Never
lift a load higher than necessary or leave suspended loads unattended.
Never
lift a load over people.
Always
keep other personnel far enough away from the lifter to avoid injury in the event of an
unexpected load release.
Always
place the power control in the inactive position and, when possible, disconnect the
power source before opening any enclosure on the lifter. (Only applicable to powered lifters)
Always
remember that modifications to the lifter may compromise its safety. Wood’s Powr-Grip
cannot be responsible for the safety of a lifter that has been modified by the customer. For
consultation, contact Wood's Powr-Grip (see LIMITED WARRANTY).
Always
employ a ground fault circuit interrupter when connecting the power cable to the power
source.

ASSEMBLY
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) Connect the power cable from the lifter to the power source as follows: Identify the label
indicating the voltage range (V) and frequency (Hz) required to power the lifter (located
where power cable connects to lifter). Wire the female connector provided to an appropriate
current-protected power source.
WARNING: Wiring must be done by qualified personnel,taking all appropriate
safety precautions.
Note: Be advised that brown-outs, overtaxed generators, extension cords, and other
conditions can reduce power input at the lifter. If the lifter does not receive adequate power
while lifting, this could result in an unexpected load release and a risk of injury to the
operator or others.
WARNING: Lifter that does not receive adequate power while lifting could
experience unexpected load release.
The power source must be equipped with a ground fault circuit interrupter, in order to reduce
the risk of electrical shocks.
WARNING: Power source must be equipped with ground fault circuit interrupter.
Make certain the power cable is routed so that it does not become tangled while operating
the lifter or hoisting equipment. Then push the power cable’s male connector into the female
connector and twist to secure them together.
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).
CAUTION: Always provide manual assistance to tilt actuator when raising lift bar
to vertical position.
Raise the lift bar of the lifter to a vertical orientation: Engage the tilt actuator as though
tilting a load to the flat position (see OPERATION: TO TILT THE LOAD); at the same time,
manually lift on the lift bar to assist the actuator’s movement, in order to avoid damaging the
actuator. Then attach the hoisting equipment hook to the lift shackle.
WARNING: Hoisting equipment hook must be fitted with restraining latch to
prevent lift shackle from slipping off under any circumstances.

Rev 13.1/9-16 7 PT10FS10TAC: #35142
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 shackle.
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. Now the lifter is operational.
4) Perform Operational and Load Tests for the lifter as directed in MAINTENANCE: TESTING
SCHEDULE.

Rev 13.1/9-16 8 PT10FS10TAC: #35142
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.3To determine whether the load is too porous or rough, 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.
• In order to avoid damaging the vacuum pads, the load's surface temperature must not exceed
the allowable Operating Temperatures (see SPECIFICATIONS). However, if such an
application cannot be avoided, Wood's Powr-Grip does offer a heat-resistant rubber
compound and other solutions which may enable you to lift loads with higher surface
temperatures. Contact Wood’s Powr-Grip or an authorized dealer for more information.
• 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.
• 1-3/16" [3 cm] is the maximum allowable thickness of loads at the maximum weight (see
SPECIFICATIONS: Load Capacity).4However, 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.
3Lifters that feature concave vacuum pads can also attach to some kinds of curved loads. Since curvature affects the lifting
capacity, contact Wood’s Powr-Grip for help in determining the Load Capacity for a particular curved load.
4This thickness is also known as “1-1/4 inch” in the American stone industry.
