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). 

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.  In order for a filter to function, the operator must empty the filter bowl before 

enough liquid accumulates to contact any portion of the filter element (see MAINTENANCE: A
