Configurations are created by installing or removing the pad frame’s extension arms, by
repositioning or removing the movable pad mounts, and by connecting or disconnecting the
vacuum hoses to certain vacuum pads. Always assemble the pad frame in a symmetrical
arrangement, to keep the lifter balanced (see illustrations).
For supporting the maximum load weight, all vacuum pads must be installed and all vacuum
hoses must be connected to the vacuum pads. For larger load dimensions, all vacuum pads and
extension arms must be installed on the pad frame. For smaller weights and dimensions, some
extension arms or vacuum pads may be removed, and the corresponding vacuum hoses may be
disconnected,
provided that the lifter still has sufficient capacity to support the load in
question
.
WARNING: Removing or disconnecting any vacuum pad reduces lifter's load
capacity.
To calculate the load capacity when some vacuum pads are disconnected, consult the Per-Pad
Load Capacity rating (see SPECIFICATIONS) and multiply by the number of pads currently in use.
Make sure all vacuum hoses are secure and routed to avoid being pinched, snagged, abraded or
otherwise damaged while the lifter is in operation.
WARNING: Make sure all vacuum hoses are coiled or routed so they cannot
become entangled, kinked or punctured during rotation or tilt.
To Connect/Disconnect Vacuum Hoses
The vacuum hose for each vacuum pad is connected to or
disconnected from the vacuum system by means of a quick
connector. To connect the vacuum hose, push the male and
female ends of the connector together until they lock. To
disconnect the vacuum hose, move the release ring on the
female end away from the male end until the connector
separates. Then clip the free end of the connector to the spring
clip on the extension arm.
Note: Whenever a quick connector is disconnected, the corresponding vacuum pad does not
contribute to the load capacity, whether or not the pad is mounted on the pad frame.
