Product Description
Vacuum cups use vacuum to mount small loads temporarily, as follows:
A manual pump removes air from between the rubber vacuum pad and
the mounting 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 mounting surface; and a release tab allows the cup to
disengage completely.
Maximum Load Capacity*
10 lbs [5 kg]. *Maximum Load Capacity includes a 3:1 safety factor and
requires the following: attachment on clean, smooth, nonporous at
surfaces; a minimum vacuum level of 17½" Hg [-59 kPa]; and a friction
coefcient 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: mounting loads on vertical
or inclined surfaces; 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° Fahrenheit [-18° to 49° Celsius]. Moisture
or contaminants can reduce the slip resistance of the cup. The red-line
indicator may not perform reliably at elevations above 5000 feet [1524
meters]; see Service.
OPERATION
To Attach
1) Clean the mounting 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).
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 vacuum
pad could bond with the surface, resulting in damage to the surface or
to the vacuum pad when it is removed.
MAINTENANCE
Service
Regularly make sure the vacuum cup's air lter is in place. If not,
discontinue use until the air lter is replaced.
Since aging and wear reduce the capacity of the rubber vacuum 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 lter 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 lter recess.
3) Wipe all residue from the cup face.
4) Allow the cup to dry and reinstall the air lter.
Storage
Store in a clean, dry location out of direct sunlight. Use the pad cover to
protect the cup face from damage.
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 vacuum 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 mounting 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 either 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.
