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

Rev 17.2/12-21 MT-10TDC-HV-C: #3509411
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 otherunsuitable 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 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

MT-10TDC-HV-C: #35094 Rev 17.2/12-2112
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 the air filters whenever their bowls
contain liquid or other contaminates, or their
elements appear dirty (see “AIR FILTER
MAINTENANCE”in SERVICE MANUAL).

Rev 17.2/12-21 MT-10TDC-HV-C: #3509413
Checking the Battery
Always check battery energy before
every lift.
Use the battery gauge to determine whether the battery needs to be charged (see “BATTERY
RECHARGE”).1Never use the lifter unless battery energy appears in the green range.
• While the power switch is in the “on” position ( ), the battery gauge automatically
shows battery energy.2
• While the power switch is in the “off”
position ( ), use the battery test
button (circled) to check the battery
energy.3
1..... If the vacuum pump is running or the battery charger is connected to an AC power source, the battery gauge will shown an inaccurate energy
level.
2..... After the pump stops running, the battery gauge requires a few moments to stabilize before it shows an accurate energy level.
3..... If the lifter has not been used since the battery was charged, the battery gauge may falsely show a high energy level. This “surface charge”
dissipates after the pump runs for about 1 minute, allowing the gauge to show accurate energy.
OPERATION

MT-10TDC-HV-C: #35094 Rev 17.2/12-2114
TOUSE THE PAD SHUTOFFS
Each pad shutoff on the pad frame controls the vacuum line to the adjacent vacuum pad.
Activating or deactivating the airflow at specific pads enables the lifter to handle loads with
different weights and dimensions (see “SPECIFICATIONS”) or to avoid holes in the load surface.
Closing any pad shutoff
reduces lifting capacity.
To support the maximum load weight and larger load
dimensions, all pads must be activated; for smaller weights
and dimensions, some pads may be deactivated, provided
that the lifter still has sufficient capacity to support the
load (see “LOAD CHARACTERISTICS”).
1A 1B
To activate a pad,
open the shutoff
valve (ie, place
lever parallel with
vacuum line —
fig. 1A).
To deactivate a
pad, close the
shutoff valve (ie,
place lever
perpendicular to
vacuum line —
fig. 1B).
To calculate the lifting capacity when some pads are deactivated, consult the Per-Pad Load
Capacity and multiply by the number of pads currently activated. Always activate pads in
a symmetrical configuration and use as many pads as possible for each load being lifted, to
maximize lifting capacity and to minimize load overhang.
OPERATION

Rev 17.2/12-21 MT-10TDC-HV-C: #3509415
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)
1A
Determine which will be the
top edge of the load while
lifting, and position the long
row of vacuum pads near
that edge (fig. 1A).
Make sure all activated pads
will fit on the load and will
be loaded evenly.
Consult the Per-Pad
Load Capacity.
2)
2A
Center the pad frame from
left to right on the load
(fig. 2A).
OPERATION

MT-10TDC-HV-C: #35094 Rev 17.2/12-2116
Sealing the Pads on the Load
1)
1A
Place the power switch in the “on” position ( — fig. 1A).1
Keep power switch in “on” position ()throughout lift.
The vacuum pump will turn on, the low vacuum warning light will remain lit until the
vacuum pads seal. This is normal.
2)
2A
Place the pads in contact with the load
surface. Then place the vacuum control
valve lever parallel with the vacuum line
(ie, in the “attach” position — , fig.
2A).2
Keep control valve in “attach”
position ()throughout lift.
Caution: Any interruption of airflow
during lifter operation could cause a
load release and personal injury.
3) Press the lifter firmly against the load to help the activated pads begin to seal.3
1..... If any powered component fails to function while the power switch is in the “on” position, examine the circuit breaker to determine whether it
has interrupted the electrical circuit to the component. Although you can reset the circuit breaker, the power interruption may indicate an
electrical problem that requires attention. Any fault must be corrected before resuming normal operation of the lifter.
2..... Do not place the vacuum control valve in the “attach” position unless the vacuum pads are contacting the load.
3..... Although a vacuum pad may become distorted during shipping or storage, this condition should correct itself with continued use.
OPERATION

Rev 17.2/12-21 MT-10TDC-HV-C: #3509417
Reading the Vacuum Gauge
A vacuum gauge shows the current vacuum level in positive inches of Hg and negative kPa:
•
1B 1C
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. 1C).
If it takes more than 5 seconds for the vacuum
level to reach 5" Hg [-17 kPa], press on any
activated 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.1If it does not:
• Make sure the vacuum switch is adjusted correctly (see SERVICE MANUAL).
• When necessary, perform the “Vacuum Test”.
1..... 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

MT-10TDC-HV-C: #35094 Rev 17.2/12-2118
TOLIFT AND MOVE THE LOAD
Interpreting the Warning Light
Never lift load unless warning devices turn off, because
this could result in load release and personal injury.
When vacuum is
sufficient to lift the
Maximum Load Capacity,
the vacuum pump and the low vacuum warning light turn off temporarily, to conserve battery
energy.
When air leaks into the vacuum system, the vacuum pump turns on and off (along with the
warning light) as necessary to maintain sufficient vacuum for lifting.
Monitoring Vacuum Indicators
1A
Monitor the low vacuum warning light and the vacuum
gauge (fig. 1A) throughout the entire lift.
Make sure vacuum indicators remain
completely visible.
If the warning light turns on and the vacuum gauge
shows a level less than 16" Hg [-54 kPa]:
1) Keep everyone away from a suspended load until
it can be safely lowered to a stable support.
Stay clear of any suspended load while
indicators warn of low vacuum.
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.
