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.

Powering up the Lifter
Place the power switch in the ON ( ) position (blue indicator light remains illuminated while
power is engaged). The power switch must remain in the ON position while operating the lifter. 4
WARNING: Never turn power off while operating lifter.
Placing the power switch in the OFF ( ) position during lifter operation could result in the
release of the load and possible injury to the operator.
4
If a vacuum pump or any other powered component fails to function while the power switch is in the ON position, examine
each circuit breaker (adjacent to power switch) to determine whether it has interrupted the electrical circuit to the component.
Although the operator can reset the circuit breaker, the power interruption may indicate an electrical problem that requires
attention. Correct any deficiency before resuming normal operation of the lifter (see wiring diagram provided).
