The lifter can accommodate various load dimensions, depending on the position of the sliding
pad arms and movable pad mounts on the pad frame (see illustration in OPERATING FEATURES).
Move the pad arms and pad mounts inward or outward on the pad frame as needed to provide
adequate support across the load surface. The vacuum pads must be arranged symmetrically, to
keep the lifter balanced.
WARNING: Make sure all vacuum hoses are coiled or routed so they do not
become entangled, kinked or punctured.
To position a pad arm, use the pull ring to remove the cotterless
hitch pin from the arm’s sliding mount. While making sure the
vacuum hose does not get pinched, slide the arm to the desired
position and align the holes for the pin. Push the pin through the
holes until the retaining ball emerges on the far side of the arm
mount. On the opposite end of the pad frame, position the
second sliding pad arm at an equal distance from the center of
the lifter.
To position each set of vacuum pads on a pad arm,
remove the cotterless hitch pins from the pad mounts,
move the pads inward or outward equal distances on the
pad arm, and secure them with the cotterless hitch pins.
Before applying the vacuum pads to a load, make sure
that all vacuum hoses are properly connected and will
not interfere with lifter operation.

"ON" position (blue indicator light remains illuminated while power is engaged). 4 The power
switch must remain in the "ON" position while operating the lifter. 5
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 (see T

After the power switch is placed in the "ON" position, the low vacuum warning light and the vacuum pumps turn on until the
lifter attains full vacuum. Since the lifter is operating in energy conservation mode at this stage, the pumps and warning light
may subsequently turn off. However, this does not indicate that the lifter is ready to lift a load.
5
If a vacuum pump fails to function while the power switch is in the "ON" position, examine the circuit breaker (below power
switch) to determine whether it has interrupted the electrical circuit to the pump. 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).
