The operator must determine whether the lifter is capable of performing each intended task, in
accordance with the SPECIFICATIONS and INTENDED USE sections of this INSTRUCTIONS
manual. In addition, all of the following preparations must be completed prior to lifting any load.
Taking Safety Precautions
The operator must be trained in all relevant industry and regulatory standards for the operation
of the vacuum lifter in its geographical location (eg, ASME B30.20 in the USA).
The operator must read and understand this
INSTRUCTIONS manual, including all WARNINGS ,
before using the lifter. If necessary, contact Wood’s Powr-Grip or an authorized dealer for
assistance.
WARNING: Always wear appropriate personal protective equipment.
The operator must wear any personal protective equipment and take any other precautions
required to handle the load safely. Consult appropriate trade association guidelines to determine
what precautions are necessary for each type of load material.

CAUTION: Examine each air filter regularly, and empty when necessary.
The lifter is equipped with one or more air filters to help protect the vacuum system from
contaminants. 3 In order for a filter to function, the operator must empty the filter bowl before

Each shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad. By
activating or deactivating the vacuum flow at specific pads, the operator can use the lifter to
handle loads of various weights and dimensions (see Maximum Load Capacity and Pad Spread in
SPECIFICATIONS). In addition, certain pads may be deactivated in order to avoid holes in the
load surface. To support the maximum load weight and larger load dimensions, all pads must be
activated; for smaller weights and dimensions, certain pads may be deactivated,
provided that
the lifter still has sufficient capacity to support the load (see B EFORE U SING THE L IFTER
preceding).

In order for the operator to use the lifter on wet load surfaces, it must be equipped with 2 or more filters that are connected in
