SAFETY
Wear personal protective
equipment that is appropriate for
the load material. Follow trade
association guidelines.
Do not remove or obscure safety
labels.
Do not make any modifications to
the lifter (see “LIMITED
WARRANTY”).
Use the lifter only in an approved
“OPERATING ENVIRONMENT”(see
“INTENDED USE”).
Do not use a lifter that is damaged,
malfunctioning, or missing parts.
Do not use a lifter if the sealing
edge of any vacuum pad is cut or
otherwise damaged.
Do not use a lifter to lift cracked or
broken glass.
Do not exceed the Maximum
Load Capacity or lift loads the
lifter is not designed for (see
“INTENDED USE”).
Do not use a lifter if the
Maximum Load Capacity or
any safety label appears to be
missing or obscured.
Make sure the contact surfaces of
the load and vacuum pads are clean
before attaching the lifter (see
“MAINTENANCE”).
Position the vacuum pads correctly
on the load before lifting (see
“OPERATION: Positioning the Lifter
on the Load”).
Do not lift a load if any vacuum
indicator shows inadequate
vacuum.
Keep unauthorized personnel away
from the lifter, to avoid injury in
case of an unintended load release.
Do not touch the vacuum release
controls during a lift.
Do not allow people to ride on the
lifter or the load.
Do not lift a load higher than
necessary or leave suspended loads
unattended.
Do not position a loaded or
unloaded lifter over people.
Before servicing a powered lifter,
place the power control in the
inactive position and, when
possible, disconnect the power source.

OPERATING FEATURES

Rev 6.0/12-19 MRTALP4-DC3: #350587
1) Remove all vacuum lifter restraints and save them with the shipping container for future
use.
2)
2A
If necessary, assemble the lift bar (item 1 in fig. 2A). Tighten
bolts (item 2 in fig. 2A) securely.
3) Adjust the lift point to optimize the lifter's hang angle:
3.1) Remove the retaining bolt (item 3 in fig. 2A) and loosen
the pivot bolt (item 4 if fig. 2A).
3.2) Move the lift point to the appropriate position.
3.3) Reinstall the retaining bolt and tighten both bolts
securely.
Note: Position the lift point to avoid contact with long
configurations of the pad frame during rotation.
4) Suspend the lifter from appropriate hoisting equipment:
4.1) Select a crane and/or hoist rated for the Maximum Load Capacity plus
the Lifter Weight.
Note: Any lifter use must comply with all statutory or regulatory standards for
hoisting equipment in your region.
4.2)
4A
4B
4C
Pull the tilt release
lever (fig. 4A) to
disengage the tilt
latch. Then raise the
lift bar (figs. 4B-C).
ASSEMBLY

4.3)
Make
sure hook
has restraining
latch (circled).
4D 4E 4F
Only use rigging rated for Maximum
Load Capacity plus Lifter Weight.
Attach the hoisting hook to the lift
point (fig. 4D-E).
Note: Use rigging (fig. 4F) as needed to
make sure the hook does not interfere with the load.
4.4) Use the hoisting equipment to remove the lifter from the shipping container. Avoid
damaging the vacuum pads.

5) Connect the electrical connectors (figs. 5A-B and figs. 5C-D) and install the 9-volt battery
for the notification buzzer as directed in “NOTIFICATION BUZZER BATTERY REPLACEMENT”on
page 37.
6) Assemble the pad frame for optimal load support (see “TOASSEMBLE/DISASSEMBLE THE PAD
FRAME”on page 9). Remove the pad covers (fig. 6A) and save them for future use, if
applicable.
7) Perform tests as required under “TESTING”on page 31.
