To Reposition (or Remove) Movable Pad Mounts 

1)  Remove the cotterless hitch pin from one movable pad mount by 

pulling on the pull ring. 

2)  Move the pad mount to the desired position on the pad frame and 

align the holes for the cotterless hitch pin in the pad mount with 
the corresponding holes in the pad frame. 

3)  Secure the pad mount by pushing the cotterless hitch pin through 

the holes until the retaining ball emerges on the far side of the pad mount. 

4)  Make sure that the vacuum hose connecting the vacuum pad to the vacuum system is not 

pinched, kinked, cut or abraded and that it will not interfere with lifter operations. 

5)  Repeat steps #1-4 to position other pad mounts as needed.  Always position vacuum pads in 

a symmetrical arrangement, and make sure that all vacuum hoses are functioning correctly. 

To remove a vacuum pad from the pad frame all together, disconnect the corresponding vacuum 
hose and remove the pad mount as directed above.  Make sure to store the pad and its mount in 

a clean, dry location to protect them from environmental exposure. 

To Install/Remove Extension Arms 

1)  Remove the cotterless hitch pin (see illustration above) from one extension arm by pulling on 

the pull ring. 

2)  Insert the end of the extension arm in its socket on the pad frame, so that the holes align for 

the cotterless hitch pin. 

3)  Secure the extension arm in the pad frame by pushing the cotterless hitch pin through the 

holes until the retaining ball emerges on the far side of the pad frame socket. 

4)  Remove the end of the quick connector from the spring clip on the extension arm, and 

connect the vacuum hose as directed above. 

5)  Repeat steps #1-4 to install other extension arms as needed for the pad frame configuration 

desired. 

6)  To remove extension arms, reverse this procedure.  Store removed extension arms in a clean, 

dry location to protect them from environmental exposure. 

About Secondary Rotation Stops 

The lifter features two sets of holes in the rotation wear plate, which function as stops for the 

rotation latch.  Rotation stops allow the operator to secure the load at each quarter turn of the 
rotation, keeping the long dimensions of an upright load either parallel or perpendicular to the 

ground.  The secondary stops are rotated approximately 30° from the primary stops, to provide 

the same load positioning when the pad frame is in a linear configuration (see illustration). 
Note:  When you are assembling a linear configuration, be sure to install extension arms in the 

two sockets as shown in the illustration, since the secondary rotation stops do not align correctly 

when the arms are placed in the other two sockets.
