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:

 

O

PERATING 

E

NVIRONMENT

). 

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 

attaching the pads (see MAINTENANCE: V

ACUUM

). 

Never exceed the Load Capacity or attempt to lift loads the lifter is not designed for (see 

INTENDED USE: L

OAD 

C

HARACTERISTICS

). 

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: T

A

TTACH THE 

P

ADS TO A 

L

OAD

). 

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).
