for cleaning. Do not use unauthorized rubber cleaners or conditioners, such as those intended
for cleaning tires or vinyl surfaces, because those products can leave a hazardous film on vacuum
pads which significantly reduces their lifting capacity (see Friction Coefficient preceding). The
use of any unauthorized cleaning agent is prohibited because it could damage the pad and/or
create a hazard to the operator or others.
WARNING: Never use solvents, gasoline or other harsh chemicals to clean
vacuum pad.
WARNING: Never use unauthorized rubber cleaners or conditioners to clean
vacuum pad.
To prevent liquid from contaminating the vacuum system during cleaning, cover the suction hole
in the recess for the filter screen or make sure the pad faces downward. Use a clean sponge or
lint-free cloth to apply an authorized cleanser and wipe the pad face clean. A toothbrush (or
similar brush with bristles that do not harm rubber ) may be used to remove contaminates
clinging to sealing edges. 6 Wipe all residue from the pad face, and allow the pad to dry
completely before using the lifter.

Cleaning).
2) Apply the lifter to a clean, smooth, nonporous surface. The surface should be flat or possess
no more curvature than the lifter is designed for (if any). 7
3) When the vacuum level registers above 16" Hg [-54 kPa] on the vacuum gauge, turn off or
disconnect the power source (as appropriate) and leave the pads attached to the surface.
4) Monitor the vacuum gauge: The vacuum level should not decrease by more than 4" Hg [-14
kPa] in 10 minutes.
WARNING: If lifter fails vacuum test, discontinue use immediately.
Correct any deficiency in the vacuum system before using the lifter. Contact Wood’s Powr-Grip
or an authorized dealer for assistance.

If these cleaning methods are not successful, contact Wood’s Powr-Grip or an authorized dealer for assistance.

Any test material used must be fully and independently supported, and capable of bearing the lifter’s weight. Do not use the
lifter to lift the test material during the vacuum test.
