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 illustration). 
To support the maximum load weight, all vacuum pads must be installed on the pad frame and 
all vacuum hoses must be connected to the vacuum pads. To support the largest load 
dimensions, all extension arms must also be installed on the pad frame. To support 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 removed, consult the Per-Pad Load
Capacity (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.
