2...... The Maximum Load Capacity is rated at a vacuum of 18 Hg [-60 kPa] on clean, smooth, nonporous flat surfaces with a friction coefficient of 1. Pad
compound, load rigidity, strength, surface conditions, overhang, angle, center of gravity and temperature can also affect the lifting capacity. A qualified
person should evaluate the effective lifting capacity for each use (see definition under “Rated Load Test”).

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 padsare 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 1.0/2-21 MRTALPCH6-DC3: #35125AUS7
1) Remove all shipping materials and save them with the shipping container for future use.
2)
2A
If necessary, assemble the lift bar (fig. 2A). Tighten the 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.1
3.3) Reinstall the retaining bolt and tighten both bolts
securely.
Note: Position the lift point to avoid contact with 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).
1..... Moving the lift point forward (away from operator) helps keep the hang angle vertical while the lifter is loaded; moving the lift point rearward
(towards operator) helps keep the hang angle vertical while the lifter is unloaded.
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”.
6) Assemble the pad frame for optimal load support (see “TOCHANGE THE PAD FRAME
CONFIGURATION”). If applicable, remove the pad covers (fig. 6A) and save them for future
use.
7) Perform tests as required under “TESTING”.
