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.

before placing it in service (see
MAINTENANCE).
WARNING: Make sure alarm is clearly audible over ambient noise at operator
position.
The volume of the alarm may be adjusted by rotating the shutter of the low vacuum warning
buzzer. Make sure the alarm is loud enough to be heard over any other noise that may be
present while the lifter is in use. In addition, the alarm must be clearly audible at the maximum
distance the operator may be from the lifter, as well as through any barriers or obstructions
between the operator and the lifter. In order to be considered clearly audible,
the alarm
volume must exceed ambient noise by at least 15 dBA at the operator position.
6
Since the Maximum Alarm Volume is 103 dBA, ambient noise must not exceed 88 dBA under any
circumstances. Furthermore, if ambient noise measures 88 dBA, the alarm volume must be set
to maximum and the operator must remain within 2 ft [60 cm] of the warning buzzer, in order for
it to be effective.

Consult CE Standard EN 457 for alternative ways to determine whether the alarm is clearly audible to operators.
