Product Description
Hand cups use vacuum 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.
  Model  Pad  Nominal Dia.  Max. Load Capacity*
LJ6VH  LJ6  6" [15 cm]  70 lbs [32 kg]
N4000, N4300, N4950  G0695  8" [20 cm]  125 lbs [57 kg]
N5000, N5300, N5450  G0725  9" [23 cm]  150 lbs [68 kg]
N5450CS, N5000CS  VPCS9  9" [23 cm]  150 lbs [68 kg]
N6000, N6300, N6450  G0750  10" [25 cm]  175 lbs [79 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 hand cups attached to the upper, horizontal surface 
of static objects in ideal conditions. Many factors can reduce the capacity, 
including: lifting a load when the cup is attached to a vertical or inclined 
surface; or lifting a load that applies leverage to the cup. See 
www.powrgrip.com for more information.
Load and Environmental Conditions
Use the cup on clean, relatively smooth, nonporous surfaces, at temperatures 
from 10° to 120° Fahrenheit [-12° 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)  Position the hand cup on the contact surface so the red line will be visible 
   if it should appear while lifting the load. CAUTION: Test the cup for staining 
   or deformation of load surfaces with light colors or soft coatings.
2)  Pump the plunger until the cup attaches completely. When the red line is 
   hidden, vacuum is sufcient for lifting.
3)  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)  Pull one of the release tabs (on 6" [15 cm] cups) or press the valve 
   release lever (on other cups) until the cup disengages completely. 
   CAUTION: Remove the cup when not in use.
MAINTENANCE
Service
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 (see 
Inspection).
If the hand cup does not function normally, the cup face may be dirty or the 
cup may require service. First clean the cup face according to the directions to 
follow. If the condition 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.
Inspection
Examine and test the cup regularly to make sure it does not exhibit 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.
•  excessive glaze or stiffness of rubber pad.
•  air lter missing from cup face.
Correct any faults before using the cup (see Service).
Storage
Store the cup in clean, dry condition within its protective carrying case.
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 or 
   the effective capacity (see SPECIFICATIONS).
•  Do not use the cup to support a person.
•  Do not place the cup face 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 cup face or 
   contact surface; applying the cup to porous materials; or applying pressure 
   against the cup 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 release tabs (on 6" [15 cm] cups) or the valve release 
   lever (on other cups) while lifting.
•  Do not attach 10" [25 cm] diameter cups to thin, fragile materials.
•  Do not use harsh chemicals (such as solvents or gasoline) or unauthorized 
   rubber cleaners and conditioners to clean the cup.
