Cleaning
Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates.
Acceptable cleaning agents include soapy water and other mild cleansers. Do not use solvents,
petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh chemicals
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 pump during cleaning, cover the suction hole
in the recess for the air filter 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. 7 Wipe all residue from the pad face, and allow the pad to dry completely before
using the lifter.

3) Monitor the hand cups' red-line vacuum indicators for approximately 2 hours: All of the red
lines must remain hidden during this time. If not, perform general maintenance (see
hand cup instructions) and repeat the test. If the problem persists, contact Wood’s Powr-Grip
or an authorized dealer for assistance.
WARNING: If hand cup fails vacuum test, discontinue use immediately.
Correct any deficiency in the hand cups before resuming normal operation of the lifter.
