SMALL VACUUM CUP
INSTRUCTIONS
SPECIFICATIONS
Product Description
Vacuum cups use vacuum to mount loads temporarily or to lift and carry
loads, as follows: A manual pump removes air from between the rubber
pad and the contact surface; a red line on the pump's plunger serves
as a vacuum indicator; a check valve allows the user to repump the cup
without removing it from the contact surface; and a release mechanism
allows the cup to disengage completely.

*Maximum Load Capacity includes a 3:1 safety factor and requires
the following: attachment on clean, smooth, nonporous flat surfaces; a
minimum vacuum level of 17½" Hg [-59 kPa]; and a friction coefficient of
1. This rating is based on tests of new vacuum cups attached to the upper,
horizontal surface of static objects in ideal conditions. Many factors can
reduce the capacity, including: attaching cups on vertical or inclined
surfaces to lift a load or to mount a load; dynamic loading (eg, mounting
loads on moving vehicles); or attaching loads that apply leverage to the
cup. See www.WPG.com for more information.
Contact Surface and Environmental Conditions
Use the cup on clean, relatively smooth, nonporous surfaces, at
temperatures from 0° to 120° F [-18° to 49° C] and elevation up to 5,000'
[1,524 m]. Moisture or contaminants can reduce the slip resistance of
the cup. Contact an authorized dealer or visit www.WPG.com for more
information.
OPERATION
To Attach
1) Clean the contact surface and, if needed, the face of the vacuum cup
(see Cleaning). CAUTION: Test the cup for staining or deformation
of surfaces with light colors or soft coatings.
2) Position the cup so the red line will be visible if it should appear while
the cup is attached.
3) Pump the plunger until the cup attaches completely. When the red
line is hidden, the cup is ready for use.
4) Check the plunger frequently to make sure the cup remains securely
attached. If the red line appears, pump the plunger until the red line
is hidden again (see WARNINGS).

CAUTION: The user must be able to monitor the red line and repump
1
the plunger whenever the cup is in use. If not, a secondary restraint
may be needed to protect mounted equipment.
To Release
1) Secure the load.
2) Pull a release tab until the cup disengages completely.
CAUTION: Remove the cup when not in use. If the cup remains
attached to a hot surface (eg, in direct sunlight) for an extended time,
the rubber pad could bond with the surface,resulting in damage to
the surface or to the pad when it is removed.
MAINTENANCE
Service
Regularly make sure the vacuum cup's air filter is in place. If not,
discontinue use until the filter is replaced. Since aging and wear reduce
the capacity of the rubber pad, it should be replaced at least once every
2 years or whenever damage is discovered.
If the cup does not function normally, the cup face may be dirty or
damaged, or the pump may require service. First clean the cup face
according to the directions to follow. If the problem persists, contact an
authorized dealer or visit www.WPG.com for assistance.
Cleaning
1) Remove the air filter from the cup face.
2) Use a clean sponge or lint-free cloth to apply soapy water or another
mild cleanser to the cup face; see WARNINGS and www.WPG.com
for more information. 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 cup face.
4) Allow the cup to dry and reinstall the air filter.
Storage
Store in a clean, dry location out of direct sunlight. Protect the cup face from
damage using the pad cover (when supplied) or another appropriate means.
WARNINGS
Failure to observe WARNINGS could damage the vacuum cup or the
load, or cause injury to the user.
• Do not use the cup to support loads that exceed the Maximum Load
Capacity or the effective capacity (see SPECIFICATIONS).
• Do not use the cup to support a person.
• Do not use the cup to support loads which could injure people if the
cup disengages unexpectedly.
• Do not place the cup face against surfaces which could damage the
sealing edge of the rubber pad.
• Avoid conditions that could cause the cup to slip or to disengage
prematurely,such as: contaminants, cuts or scratches in the cup face
or contact surface;applying the cup to porous materials; or applying
pressure against the cup edge.
• Do not use the cup 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 any release tab while using the cup.
• Do not leave the cup in use and unattended.
• Do not use harsh chemicals (such as solvents or gasoline) or
unauthorized rubber cleaners and conditioners to clean the cup.
