To Reposition (or Remove) Movable Pad Mounts
1) Remove the cotterless hitch pin from one movable pad mount.
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. To ensure maximum
effectiveness of the dual vacuum system, make sure that the vacuum pads are connected in
an equal and alternating distribution to the 2 circuits of the vacuum system. Always position
vacuum pads in a symmetrical arrangement, and make sure that the corresponding 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.
Note: When you are assembling a linear configuration (see illustration), a third vacuum pad may
be mounted in line on each of two pad arms. Although these additional pads do help prevent
load breakage,
they must not be included in calculations of load capacity , because each
arm of the pad frame has a maximum structural capacity of 350 lbs [159 kg].
To Install/Remove Extension Arms
1) Remove the cotterless hitch pin from one extension arm.
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) Use a quick connector to connect the corresponding 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.
