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 hook has restraining latch

(arrow in fig. 2B).

Only use rigging rated for Maximum

Load Capacity plus Lifter Weight.

Attach the hoisting hook to the eye

of the lift bracket (arrow in fig. 2A).

Use a clevis if the eye is too small

for the hook.

Note: Use rigging (figs. 2B-C) as

needed tomake sure the hook does not interfere with the load.

Remove the pad cover (fig. 3A) and save it for future use.

Mount the vacuum generating system in a location suitable

for operating both the lifter and the hoisting equipment

(mounting hardware not supplied; mounting holes are

shown in fig. 4A).

Securely position vacuum hose to avoid damage

during lifter operation.

Note: Consult the hoisting equipment manufacturer to determine how to mount the

vacuum generating system in a safe location that will not interfere with hoisting.

MT1TL6FAIR: #35080 Rev 9.0/5-238

Qualified service personnel should install female

quick connector (supplied) on air line, when

needed.

Securely position air line to avoid damage during

lifter operation.

5A 5B

Connect the lifter to an

appropriate compressed air

supply (see Power Source

under “SPECIFICATIONS”):

Then connect the female

quick connector to the male

quick connector mounted

on the air supply valve (figs.

5A-B).

6) Adjust the air pressure regulator to supply 80 psi [550 kPa]:1

Note: Vacuum pad must not be attached to any surface while adjusting the regulator.

6.1)

6A 6B 6C

Place the air

supply valve

lever parallel

with the

vacuum line

(ie, in the

“on”position

— fig. 6A).

6.2) Pull up the

adjustment

collar on top

of the

regulator

(fig. 6B), and turn the collar clockwise to increase pressure or counter-clockwise to

decrease pressure (fig. 6C).

1..... Exceeding this pressure consumes more air and does not improve lifter performance.

ASSEMBLY

Rev 9.0/5-23 MT1TL6FAIR: #350809

6.3)

When the pressure gauge registers a

minimum air pressure of 80 psi [550 kPa],

push down the collar to lock it in place

(fig. 6D).

Note:

Place the air supply valve lever perpendicular to the air

line (ie, in the “off” position — fig. 6E) when the lifter is not in

use; otherwise, the air compressor will cycle frequently.

7) Perform tests as required under “TESTING”.

INTENDED USE

LOAD CHARACTERISTICS

Do NOT lift explosives, radioactive

substances or other hazardous materials.

Make sure the vacuum lifter is intended

to handle each load according to these

requirements:

• The load weight must not exceed the Maximum Load Capacity.

• The load must be a single piece of relatively nonporous material with a flat and

relatively smooth contact surface.1, 2To determine whether the load is too porous or

rough, perform the “Lifter/Load Compatibility Test”.

• The load's contact surface must be able to obtain a friction coefficient of 1 with the lifter's

vacuum pad (see “Pad-to-Load Friction Coefficient”). Otherwise, the capacity should be

derated appropriately.

• The load's surface temperature must not exceed the Operating Temperatures.3

• The load's minimum length and width are determined by the current Pad Spread

(see “SPECIFICATIONS”).

• The load's maximum length and width are determined by its allowable overhang.4

• Although load thickness is not restricted, it may affect the lifter’s hang angle and the

amount of operator effort required for handling loads.

Note: Standard vacuum pads can stain or deform load surfaces with light colors or soft

coatings. Test such surfaces for damaging effects before using the lifter on them.5

1..... Although concave vacuum pads can also attach to some curved loads, curvature can reduce lifting capacity. Contact WPG for more information.

2..... A “single piece” of material includes curtainwall assemblies, unitized glazing systems and similar construction units.

3..... Vacuum pads made from a heat-resistant rubber compound can enable you to lift loads with higher surface temperatures. Contact WPG or an

authorized dealer for more information.

4..... The allowable overhang is the amount of load material that can extend sideways beyond the vacuum pad without breaking or otherwise being

damaged. This depends on the load material, its thickness, and the angle of handling (if any). Since every material has different physical

properties, the allowable overhang must be evaluated separately for each load type. Contact WPG or an authorized dealer for more

information.

5..... Alternative rubber compounds are available for these purposes. Contact WPG or an authorized dealer for more information.

Indirect loading

can reduce

lifting capacity.

Rev 9.0/5-23 MT1TL6FAIR: #3508011

INDIRECT LOADING

Make sure to account for dynamic loading or other inadvertent

loading that can negatively affect lifting capacity, such as:

• Weight amplification that results when a loaded vacuum lifter

abruptly starts/stops moving, changes direction or bounces up

and down (eg, when a telehandler transports a loaded lifter across rough terrain).

• External force that effectively increases the weight of a lifter’s attached load (eg, when a

load of sheet material reacts to wind gusts).

OPERATING ENVIRONMENT

Make sure the lifter is suitable for each work environment, given the following restrictions:

•

Never use lifter

in dangerous

environments.

This lifter is not intended for any environment that is

dangerous to the operator or damaging to the lifter. Avoid

environments containing explosives, caustic chemicals and

other dangerous substances.

• The work environment is limited by the Operating Elevation and Operating

Temperatures.1, 2

• The lifter is not designed to be watertight.

Moisture can reduce

lifting capacity.

Do not use it

in rain or other unsuitable conditions.

CE/UKCA — A secondary positive holding device is required to lift loads on construction sites.

DISPOSAL OF THE LIFTER

After the Service Life of the lifter has ended (see “SPECIFICATIONS”), dispose of it in compliance

with all local codes and applicable regulatory standards.

1..... Although lifter use may be possible at higher elevation, lifting capacity is reduced whenever the lifter is unable to attain vacuum in the green

range on the vacuum gauge. Contact WPG for more information.

2..... Special provisions may allow the lifter to operate outside the specified temperature range. Contact WPG for more information.

INTENDED USE

MT1TL6FAIR: #35080 Rev 9.0/5-2312

OPERATION

BEFORE USING THE LIFTER

Determine whether the vacuum lifter is capable of each intended task (see “SPECIFICATIONS”

and “INTENDED USE”). Then complete the following preparations:

Taking Safety Precautions

•

Read all directions and safety rules before using

lifter.

Always wear appropriate personal protective

equipment.

Be trained in all industry

and regulatory standards

for lifter operation in your

region.

• Follow trade association

guidelines about precautions needed for each load material.

Performing Inspections and Tests

• Follow the “INSPECTION SCHEDULE”and “TESTING”.

•

Examine air filters regularly

and service when needed.

Service each air filter whenever its bowl contains

liquid or other contaminants or its element

appears dirty (see “AIR FILTER MAINTENANCE” in

SERVICE MANUAL).

Rev 9.0/5-23 MT1TL6FAIR: #3508013

TOATTACH THE PAD TO ALOAD

Generating Airflow

Place the air supply valve lever in the “on” position (fig. 1A — see ).

Never place air supply valve lever in “off” position while

operating lifter.

The vacuum pump is designed to run continuously. Any interruption of

airflow during lifter operation could result in an unintentional load release

and personal injury (see “In Case of a Power Failure”).

Positioning the Lifter on the Load

Make sure the contact surfaces of the load and vacuum pad

are clean (fig. 1B — see “Pad Cleaning”).

Determine which will be

the top edge of the load

while lifting, and position

the vacuum pad near that

edge, centering the pad

from left to right (fig. 2B).

Make sure the pad will fit

entirely on the load.

OPERATION

MT1TL6FAIR: #35080 Rev 9.0/5-2314

Sealing the Pad on the Load

Place the vacuum pad in contact with the load

surface. Then press the lifter firmly against the load

to help the vacuum pad begin to seal (fig. 1A).1

Reading the Vacuum Gauge

A vacuum gauge shows the current vacuum level in positive inches of Hg and negative kPa:

•

1B 2B

Green range (>16" Hg [-54 kPa]): Vacuum

level is sufficient to lift the maximum load

weight (fig. 1B).

•Red range (<16" Hg [-54 kPa]): Vacuum level

is not sufficient to lift the maximum load

weight (fig. 2B).

If it takes more than 5 seconds for the vacuum level to reach 5" Hg [-17 kPa], press on the

vacuum pad until it seals completely.

Once the pad has sealed, the lifter should be able to maintain sufficient vacuum for lifting,

except when used above the maximum Operating Elevation.2If it does not, perform the

“Vacuum Test”.

1..... Although a vacuum pad may become distorted during shipping or storage, this condition should correct itself with continued use.

2..... If the lifter is used above the maximum Operating Elevation (see “SPECIFICATIONS”), it may not be able to maintain sufficient vacuum for lifting.

Contact WPG for more information.

OPERATION

Rev 9.0/5-23 MT1TL6FAIR: #3508015

TOLIFT AND MOVE THE LOAD

Interpreting the Vacuum Gauge

Never lift load unless vacuum gauge registers

in the green range, because premature lifting

could result in load release and personal injury.

Vacuum is sufficient to lift the

Maximum Load Capacity

whenever the vacuum gauge registers

in the green range.

Monitoring the Vacuum Gauge

Monitor the vacuum gauge (fig. 1A) throughout the

entire lift.

Make sure the vacuum gauge remains

completely visible.

The vacuum pump runs continuously to maintain

sufficient vacuum for lifting the maximum load

weight. However, if the vacuum gauge shows a

level less than 16" Hg [-54 kPa]:

Stay clear of any suspended load while

gauge warns of insufficient vacuum.

Keep everyone away from a

suspended load until it can be safely

lowered to a stable support.

2) Stop using the lifter until the cause of the vacuum loss can be identified: Conduct the

“Pad Inspection” and perform the “Vacuum Test”.

3) Correct any faults before resuming normal operation of the lifter.

Controlling the Lifter and Load

When the lifter is ready, use the hoisting equipment to raise

the lifter and load as needed.

Use the control handle (fig. 1B) to keep the lifter and load in

the required position.

Once there is enough clearance, you may move the load as

required.

OPERATION

MT1TL6FAIR: #35080 Rev 9.0/5-2316

In Case of a Power Failure

Although the lifter is designed to support the load for at least 5 minutes without power, this

depends on many factors, including the “LOAD CHARACTERISTICS”and the condition of the vacuum

pad (see “VACUUM PAD MAINTENANCE”).

Stay clear of any suspended

load during power failure.

If a power failure occurs, keep everyone away from a

suspended load until it can be safely lowered to a stable

support. Correct any faults before resuming normal

operation of the lifter.

TOTILT THE LOAD

1) Make sure the load has enough

clearance to tilt without

contacting anyone or anything.

2) Tilt the load tothe position needed:

• Tilting the load to the upright position

happens automatically when it is lifted

(fig. 1A).

• Tilting the load to the flat position is

accomplished during the landing (see

section below).

TOLAND THE LOAD

•

For a landing in the upright position,

simply lower the load onto an

appropriate support.

• For a landing in the flat position, lower

the lifter until the bottom edge of the

load is supported.

Then continue to lower the lifter, carefully

allowing the load and lifter to tilt forward

and downward (fig. 1B and inset) until the

entire load rests on the support.

OPERATION

Rev 9.0/5-23 MT1TL6FAIR: #3508017

TORELEASE THE PAD FROM THE LOAD

Make sure load is at rest and fully supported before releasing

vacuum pad.

Do not move lifter until pad releases completely, because such movement could

result in load damage or personal injury.

1) Initiate release of the vacuum pad:

• P

ull a release tab on the pad (circled

in fig. 1A), or;

•

Place the air supply valve lever in the “off” position (fig. 1B).

2) Make sure the pad releases completely from the load.

3) Perform the Every-Lift Inspection (see “INSPECTION SCHEDULE”).

Now, the lifter can be attached immediately to another load.1

1..... If you released the vacuum pad by pulling its tab and the next lift is not imminent, place the air supply valve lever to the “release” position until

you are ready to lift another load.
