Make sure load is at rest and fully supported before releasing 
vacuum pads.

1)  

1A

Push the vacuum release button ( 

 — fig. 1A), to break 

the vacuum seal.

2)  

Do not move lifter until pads release 
completely, because such movement 

could result in load damage or personal injury.

Continue to hold the release button 

until the vacuum pads release the 
load completely.  Otherwise, the 
lifter will automatically reattach.

3)  Before you lift another load, perform the Every-Lift Inspection (see 

“I

1)  Place the power switch in the “off” position (

).

2)  Use the hoisting equipment to lower the vacuum lifter gently onto a 

stable support. Then detach the hoisting hook from the lift point. 

Caution: 

 Do not set the lifter on surfaces that could soil or damage vacuum 

pads.
