Maximum Load

Capacity1

1...... The Maximum Load Capacity is rated at a vacuum of 16" Hg [-54 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”).

Make sure to consider all possible

effects of “INDIRECT LOADING” on lifting

capacity (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”).

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.

Rev 32.0/11-23 MT-10TAC: #350897

ASSEMBLY

1) Remove all shipping materials and save them with the shipping container for future use.

2) Suspend the lifter from appropriate hoisting equipment:

2.1)

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.

2.2)

Make sure the lift slings

are securely attached to

the lifter (circled in fig.

2A).

2.3)

Make

sure

hook has

restraining

latch (circled

right).

Attach the free eye of

each lift sling to the

hoisting equipment

hook (fig. 2B).1

Only use clevis and clevis pin rated for

Maximum Load Capacity plus Lifter Weight.

Note: A large clevis makes it

easier to connect or

disconnect the lift slings.

2.4) Use the hoisting equipment to remove the lifter from

the shipping container. Avoid damaging the vacuum

pads.

Remove the pad covers (fig. 2C) and save them

for future use.

1..... If the lifter has a Center Spool Lift Bar, disregard the directions about lift slings. Instead, attach the hoisting equipment hook directly to the lift

spool. All other directions and warnings still apply.

MT-10TAC: #35089 Rev 32.0/11-238

3) Attach the vacuum pump assembly securely to the hoisting equipment in a protected

location where the vacuum package will move with the lifter and will not interfere with

hoisting equipment (see arrows in fig. 3A for two potential mounting locations).1, 2

Make sure power source has ground fault circuit

interrupter.

Connect the power cable:

4.1)

Wiring must be done by qualified

service personnel, taking all

appropriate safety precautions.

Wire the female connector provided

to an appropriate power source, as

indicated on the label attached.

4.2) Route the power cable so that it does not become damaged during operation.

4.3)

4A 4B

Insert the power cable’s

male connector into the

female connector and twist

to secure them together

(figs. 4A-B).

5) Perform tests as required under “TESTING”.

1..... For lifters equipped with the Frame-Mounted AC Power System, disregard the directions about mounting the vacuum pump assembly on the

hoisting equipment.

2..... Consult the hoisting equipment manufacturer to determine how to mount the vacuum pump assembly in a safe location that will not interfere

with hoisting equipment operation.
