Generating Airflow
Place the power switch in the “on” position ( ), to engage the
vacuum pump.
1
Keep pump running
throughout lift.
The lifter is designed for the vacuum pump to run continuously.
Placing the power switch in the “off” position (
) during lifter
operation could result in a load release and personal injury (see “In Case of a Power Failure” on
page 20).
Positioning the Lifter on the Load
1)
1A
Make sure the contact surfaces of the load and vacuum pads
are clean (fig. 1A; see “Pad Cleaning” on page 30).
2)
2A
Center the pad frame on the load (fig. 2A).

1..... If any powered component fails to function while the power switch is in the “on” position, make sure the lifter is connected correctly to an
appropriate power source (see “ASSEMBLY”). If so, examine each circuit breaker (next to power switch) to determine whether it has
interrupted the electrical circuit to the component. Although you can reset the circuit breaker, the power interruption may indicate an
electrical problem that requires attention. Any fault must be corrected before resuming normal operation of the lifter.
2..... The lifter is designed to handle the maximum load weight when the load’s center of gravity is positioned within 2" [5 cm] of the pad frame’s
center point. Uncentered loads may rotate unexpectedly or interfere with the lifter’s tilt capability.
