OPERATION
To Attach
1) Position the hand cup on the
contact surface so the red line
will be visible if it should
appear while lifting the load.
Caution: Some rubber compounds may stain
light surfaces or deform soft coatings. When
in doubt, test a sample of such materials for
permanent effects.
2) Press the rubber pad against the load as
needed to form a continuous seal.
Caution: Make sure the load is supported as
needed to prevent breakage.
3) Pump the plunger until the cup attaches
completely. When the red line is hidden,
vacuum is sufficient for lifting.
4) Check the plunger frequently to make sure
the cup remains securely attached. If the red
line appears while lifting, set down the load
immediately and pump the plunger until the
red line is hidden again (see WARNINGS).
To Release
1) Set the load on a secure support.
2) Press the valve release lever until the cup
disengages completely.
Caution: Remove the cup when not in use.
MAINTENANCE
Service
If the hand cup does not function normally, first
clean the rubber pad according to the directions
to follow. If the condition persists, see
TROUBLESHOOTING.
Note: Replace the pad at least once
every 2 years or whenever damage is discovered
(see Inspection).
Cleaning
1) Remove the air filter from
from the rubber pad.
2) Use a clean sponge or
lint-free cloth to apply
soapy water or another
mild cleanser to the pad face (see WARNINGS).
Caution: To prevent liquid from contaminating
the pump, hold the cup face-down or cover
the suction hole in the filter recess.
3) Wipe all residue from the pad face.
4) Allow the pad to dry and reinstall the air filter.
Inspection
Inspect the cup regularly for the following faults:
cuts or damage to sealing edges of rubber pad
•
cracks or dents in handle or pump
•
reappearance of red line soon after
•
attaching cup
sluggishness or dramatic changes in pump
•
action
slick surface or stiffness of rubber pad.
•
air filter missing from pad face
•
Correct any faults before using the cup (see
Service).
Storage
Store the cup in clean, dry condition within its
protective carrying case.

Moisture or contaminants can reduce the slip resistance of the rubber pad.
1
2 The Maximum Load Capacity is based on lifting under controlled conditions with new hand cups attached to horizontal
load surfaces. Many factors can reduce the capacity, such as lifting a load when the cup is attached to a vertical or inclined
surface, or lifting a load that applies leverage to the cup. Contact an authorized dealer or WPG for more information.
Extreme surface variation may prevent these cups from attaching or remaining attached.

Caution: Do not attach these cups to thin, fragile materials.

WARNINGS
Failure to observe WARNINGS could damage the
hand cup or the load, or cause injury to the user.
• Do not use the cup to lift loads that exceed the
Maximum Load Capacity (see SPECIFICATIONS).
Do not use the cup to support a person.
•
Do not leave a cup unattended which could
•
injure people if it disengages unexpectedly.
• Do not place the rubber pad against surfaces
which could damage the sealing edges.
• Avoid conditions that could cause the cup
to slip or to disengage prematurely, such as:
contaminants, cuts or scratches in the pad
face or load surface; attaching the cup to
porous materials; or applying pressure
against the pad edge.
• Do not use the cup to lift when the red line
is visible. If the red line reappears frequently,
discontinue use and see Service.
• Do not allow anything to interfere with free
movement of the plunger while the cup is attached.
• Do not touch the valve release lever while lifting.
• Do not use harsh chemicals (such as
solvents or gasoline) or rubber cleaners and
conditioners to clean the pad.
