The lifter can accommodate various load dimensions, depending on the position of the movable
pad mounts on the pad frame. Move the pad mounts inward or outward on the pad frame as
needed to provide adequate support across the load surface. The pad mounts must be arranged
symmetrically, to keep the lifter balanced.
WARNING: Make sure vacuum hoses are coiled or routed so they do not become
entangled, kinked or punctured.
To position a pad mount, use the pull ring to remove the cotterless
hitch pin from the pad frame. While making sure the vacuum hose
does not get pinched, move the pad mount 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 mount. On
the opposite end of the pad frame, position the corresponding pad
mount at an equal distance from the center of the lifter. Before applying the vacuum pads to a
load, make sure that all vacuum hoses are routed correctly and will not interfere with lifter
operation.

"ON" position (blue indicator light remains illuminated while power is engaged). 5 The power
switch must remain in the "ON" position while operating the lifter. 6
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

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.
6
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).
