General Maintenance
Inspect the Hand Cup Regularly:
• Make sure the air filter is in place; if not, discontinue use until the filter is replaced.
• Examine the plunger assembly and handle for dents, cracks or other damage.
• Make sure the face of the vacuum pad feels grippy (not slick). Otherwise, replace the pad.
• Examine the vacuum pad for cuts or roughness on the sealing edge (see Inspect the Sealing Edge below).
• Periodically test the cup for excessive leakage (see Leak-Test the Hand Cup below), sluggishness
in plunger action or radical changes in the number of strokes needed to keep the red line hidden.
• If the cup does not function normally, review the TROUBLESHOOTING GUIDE (overleaf) to determine
what corrective action is needed.
Clean the Vacuum Pad:
• Remove the air filter from the pad face.
• Use a clean sponge or lint-free cloth to apply soapy water or another mild cleanser to the pad face.
Never use solvents or rubber conditioners as a cleaning agent
(see WARNINGS).
• To prevent liquid from contaminating the pump during cleaning, hold the cup facedown
or cover the suction inlet in the filter recess.
• Wipe all residue from the pad face and allow the cup to dry.
• Reinstall the air filter.
Inspecting and Testing the Cup for Leakage
Inspect the Sealing Edges:
• Slowly draw your finger along the entire length of the sealing edge, to check for roughness or
foreign material.
• Examine the sealing edge for cuts by bending the edge of the pad face towards you to create a hump,
turning the hand cup as necessary.
• If cuts or cracks are present in a sealing edge, a V-shaped gap will appear.
• Any pad that exhibits a gap or excessive roughness in a sealing edge must be replaced.
Leak-Test the Hand Cup:
• Attach the cup to a clean, smooth, scratch-free piece of glass or metal for approximately 2 hours.
• The red line on the plunger serves as a vacuum indicator:
▪ If the red line
does not
appear during the test period, the cup is usable.
▪ If the red line
does
appear, perform general maintenance and repeat the test.
• If the problem persists, check the TROUBLESHOOTING GUIDE (overleaf) to identify possible causes
and appropriate corrective actions.
• If these measures do not restore the cup to normal performance, contact the Wood's Powr-Grip
Customer Service department or an authorized dealer for assistance.
