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 pads(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
• 1" [2.5 cm] is the allowable thickness at Maximum Load Capacity.5
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.6
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 pads 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..... However, the allowable thickness increases as load weight decreases. Contact WPG for more information.
6..... Alternative rubber compounds are available for these purposes. Contact WPG or an authorized dealer for more information.

P1-DC3: #35123 Rev 5.2/12-2110
OPERATING ENVIRONMENT
Make sure the vacuum lifter is intended for use in 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.
Metal particles and similar environmental contaminants could result in
vacuum pump failure.
• The work environment is limited by the Operating Elevation and Operating
Temperatures.1, 2
• The lifter is not designed to be watertight.
Moisture can result in
reduced lifting capacity.
Do not
use it in rain or other unsuitable conditions.
DISPOSAL OF THE LIFTER
After the Service Life of the vacuum lifter has ended (see “SPECIFICATIONS”), dispose of it in
compliance with all local codes and applicable regulatory standards.
Note: Special disposal regulations may apply to the battery.
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

Rev 5.2/12-21 P1-DC3: #3512311
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.
Selecting a Screen Language
When the lifter is powered up for the first time, the Intelli-Grip®
control unit prompts the operator to select a language for the LCD
screen. Use the buttons as follows:
• To scroll down, press the “release” button ( ).
• To scroll up, press the “attach” button ( ).
• To select a language, press the “function” button ( ).1
Note: A similar process is used to navigate all menus.
1..... To change the language again, refer to the “INTELLI-GRIP®OPERATOR MENUS” section of the SERVICE MANUAL.

P1-DC3: #35123 Rev 5.2/12-2112
Performing Inspections and Tests
• Follow the “INSPECTION SCHEDULE”and “TESTING”.
•
Examine air filters regularly
and service when needed.
Service the 2 air filters whenever a bowl contains
liquid or other contaminates, or an element
appears dirty (see “AIR FILTER MAINTENANCE” in
SERVICE MANUAL).
•
Make sure
notification
buzzer can be
heard over noise
at operator
position.
Make sure the notification buzzer is clearly
audible at the maximum distance between the
operator and the lifter, despite any barriers or
obstacles.1, 2
Checking the 12-Volt Battery
Always check battery
energy before every lift.
While the lifter is powered up, a battery gauge on the LCD
screen displays the current energy level.3, 4
• If battery energy is in the red range, discontinue lifter
use and charge the battery (see “12-VOLT BATTERY
RECHARGE”).
• If battery energy continues to decrease and you try to
attach the lifter to a load, the notification buzzer will
sound continuously and the LCD screen will display “Lockout (low 12V battery)”, along
with a diagnostic code (see “INTELLI-GRIP® DIAGNOSTIC CODES”). In this case, you must
charge the battery in order to continue using the lifter.
1..... Maximum buzzer volume is 95 dBA at 2' [60 cm]. If CE or UKCA Standards apply, consult EN 7731 to make sure the notification buzzer is
compliant.
2..... The “Vacuum Test” provides a convenient opportunity to check this.
3..... If the lifter remains in “Power Save” mode for a long time, the pump will run periodically to test the battery.
4..... If the battery charger is connected to an AC power source, the reading on the battery gauge will not be accurate and “Replace 12V battery?”
may appear on the LCD screen, because the system cannot accurately evaluate the battery.
OPERATION

Rev 5.2/12-21 P1-DC3: #3512313
Preparing to Use the Remote Control System
1 EMERGENCY DISCONNECT BUTTON
2 TRANSMISSION INDICATOR LIGHT
3 “RELEASE” BUTTON
4 “ATTACH” BUTTON
5 POWER/“FUNCTION” BUTTON
1A
The optional radio transmitter (fig. 1A) and radio
receiver enable you to activate the lifter's “attach”
and “release” functions at distances up to 250' [76 m],
provided you have a clear and direct view of the lifter and
its status indicators.
To operate a lifter remotely, follow these safety rules:
• Visually verify the status of the lifter and load prior
to lifting.
Make sure nearby personnel are aware
of intended remote control actions.
• Monitor the lifter at all times to make sure it is
functioning as intended.1
• Be sure the load is lowered and supported correctly
before releasing it (see following sections).
Note: To prevent any radio transmission, press the
emergency disconnect button.2
1..... The Remote Control System is designed to prevent multiple lifters from responding. Nevertheless, radio-controlled lifters should be tested to
make sure each transmitter controls only one lifter.
2..... To reset the emergency disconnect button, twist the button clockwise and allow it to spring outward to its original position.
OPERATION

P1-DC3: #35123 Rev 5.2/12-2114
TOATTACH THE PADS TO ALOAD
Make sure the contact surfaces of the load and vacuum pads are clean (see
“Pad Cleaning”).
Positioning the Lifter on the Load
1) Center the pad frame on the load.1
2) Make sure all vacuum pads will fit on
the load and will be loaded evenly.
Consult the Per-Pad Load
Capacity.
3) Place the vacuum pads in contact with
the load surface.
1..... The lifter is designed to handle the maximum load weight when the load’s center of gravity is positioned within 2" [5 cm] of the lifter’s rotation
axis. Uncentered loads may rotate or tilt unexpectedly.
OPERATION

Rev 5.2/12-21 P1-DC3: #3512315
Powering up the Lifter
1A
Press the lifter's power button ( — fig. 1A). The
vacuum pump will run for a few seconds, as a
normal function of the Intelli-Grip®self-diagnostics.
The lifter automatically tests the 9-volt battery for
the notification buzzer each time the lifter is
powered up. When this battery runs down, the
LCD screen displays “Replace 9V battery?” and the
buzzer chirps once per minute. Replace the battery
as needed (see “NOTIFICATION BUZZER BATTERY
REPLACEMENT”).
1B
To use the optional Remote Control System, briefly hold the
power button ( — fig. 1B) on the radio transmitter to
activate it.1
1C
Note: When you hold any button on the transmitter, the
transmission indicator light flashes green if the transmitter is
activated.
Sealing the Pads on the Load
Press the lifter’s “attach” button ( — fig. 1 C ).
Keep “attach” function
activated throughout lift.
1..... The radio transmitter turns off automatically after a period of inactivity.
OPERATION

2B
P1-DC3: #35123 Rev 5.2/12-2116
To use the optional Remote Control System, press the “attach”
button ( — fig. 1D) on the radio transmitter.
The vacuum pump will run until the vacuum pads seal completely. If the lifter takes too long to
attach, the notification buzzer chirps and the LCD screen displays “Vacuum not increasing
normally”, along with a diagnostic code (see “INTELLI-GRIP® DIAGNOSTIC CODES”). In this case, press
the lifter firmly against the load to help the pads begin to seal.1
Reading the Vacuum Gauges
The 2 vacuum gauges of the dual vacuum system show the current vacuum level in positive
inches of Hg and negative kPa:
•
1A 1B
Green range (>16" Hg [-54
kPa]): Vacuum level is sufficient
to lift the maximum load weight
(fig. 1A).
• Red range (< 16" Hg [-54 kPa]):
Vacuum level is not sufficient to
lift the maximum load weight
(fig. 1B).2
If it takes more than 5 seconds for the
vacuum level to reach 5" Hg [-17 kPa]
on either vacuum gauge, press on any
vacuum pad that has not yet sealed.
Once the pads have sealed, the lifter should be able to maintain sufficient vacuum for lifting,
except when used above the maximum Operating Elevation.3If 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..... The gauge face colors do not correspond with the circuit colors.
3..... 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 5.2/12-21 P1-DC3: #3512317
TOLIFT AND MOVE THE LOAD
Lift bar must be vertical to lift
load.
Interpreting the Lift Light
Never lift load unless lift
light is illuminated,
because premature lifting could
result in load release and
personal injury.
When vacuum is sufficient to lift the
Maximum Load Capacity, the vacuum
lift light turns on automatically and the
vacuum pump turns off temporarily, to
conserve battery energy.
Monitoring Vacuum Indicators
1A
Monitor the vacuum lift light and both vacuum
gauges throughout the entire lift (fig. 1A).
Make sure all vacuum indicators remain
completely visible.
The vacuum pump turns on and off to overcome any
leakage. However, if the leak rate is greater than
normal, the notification buzzer chirps and the LCD
screen displays the message “Vacuum decrease on
circuit #”, along with a diagnostic code (see “INTELLI-
GRIP® DIAGNOSTIC CODES”).1Such leaks can cause the
battery to be discharged more quickly.
If the vacuum pump is unable to overcome leakage, the notification buzzer sounds
continuously, the lift light turns off, and the LCD screen displays the message “INSUFFICIENT
VACUUM!”, along with a diagnostic code (see “INTELLI-GRIP® DIAGNOSTIC CODES”). If this happens:
1)
Stay clear of any suspended load while
indicators warn of low vacuum.
Keep everyone away from a
suspended load until it can be safely
lowered to a stable support.
1..... Automatic leak detection is not a substitute for performing the “Vacuum Test”, required by the “INSPECTION SCHEDULE”and “TESTING”. Sensitivity
of leak detection can be adjusted (see “INTELLI-GRIP® OPERATOR MENUS” in SERVICE MANUAL).
OPERATION

P1-DC3: #35123 Rev 5.2/12-2118
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
1A
When the lifter is ready, use the hoisting
equipment to raise the lifter and load as
needed.
Use a control handle (circled in fig. 1A) to keep
the lifter and load in the required position.
Once there is enough clearance, you may
move the load as required.
In Case of a Power Failure
In the event of a battery failure or electrical system failure, the notification buzzer will sound
continuously.
Although the vacuum reserve tanks are 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 vacuum pads (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 lowered safely to a stable
support. Correct any faults before resuming normal
operation of the lifter.
