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.
Nominal Size Maximum Load Capacity*
3" [8 cm] diameter 15 lbs [7 kg]
3" x 6" [8 cm x 15 cm] 40 lbs [18 kg]
4½" [11 cm] diameter 40 lbs [18 kg]
6" [15 cm] diameter 70 lbs [32 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: 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.powrgrip.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 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).
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 lter is in place. If not, discontinue use
until the lter is replaced.
VACUUM CUP
INSTRUCTIONS
- for all cup sizes listed hereafter -
Products are manufactured under an
ISO 9001 quality management system
Rev. 1.4 / 08-13 Instruction Sheet 32630 SC
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.powrgrip.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.powrgrip.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. 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.
