Each shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad. By
activating or deactivating the vacuum flow at specific pads, the operator can use the lifter to
handle loads of various weights and dimensions (see Load Capacity and Pad Spread in
SPECIFICATIONS). In addition, certain pads may be deactivated in order to avoid holes in the
load surface. To support the maximum load weight and larger load dimensions, all pads must be
activated; for smaller weights and dimensions, some pads may be deactivated,
provided that
the lifter still has sufficient capacity to support the load (see INTENDED USE: L
OAD
C
HARACTERISTICS
).
WARNING: Closing any pad shutoff reduces lifting capacity.
To activate a pad, open the pad shutoff (place valve lever parallel with
vacuum line); to deactivate a pad, close the pad shutoff (place valve lever
perpendicular to vacuum line). To calculate the lifting capacity when some
pads are deactivated, consult the Per-Pad Load Capacity rating (see
SPECIFICATIONS) and multiply by the number of pads currently
activated.
Note that calculated capacities may not exceed the
Maximum Load Capacity (see SPECIFICATIONS). Always activate
pads in a symmetrical configuration, to keep the lifter balanced while
lifting, and use as many pads as possible for each load being lifted, to maximize lifting capacity
and to minimize load overhang.

the “ON” position, to engage the vacuum pump. The lifter is designed for the vacuum pump to
run continuously.
WARNING: Never place air supply valve in "OFF" position while operating lifter;
keep pump running throughout lift.
The air supply valve must remain in the “ON” position while operating the lifter. Placing the air
supply valve in the “OFF” position during lifter operation could result in the release of the load
