Cleaning
Regularly clean the face of each vacuum pad to remove oil, dust and any other contaminates.
Acceptable cleaning agents include soapy water, glass cleaner and alcohol. Do
not
use other
solvents, petroleum-based products (including kerosene, gasoline and diesel fuel) or any harsh
chemicals for cleaning, because they can damage the pad and create a hazard to the operator or
others.
WARNING: Never use solvents, gasoline or other harsh chemicals 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 appropriate 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.

Rinse all residue from the pad face, and allow the pad to dry
completely before using the lifter.

Test the vacuum system for leakage routinely, as directed in the preceding I
NSPECTION
and
T

S
CHEDULES
.
1) Clean the face of each vacuum pad as previously directed (see V
ACUUM
P
AD
M
AINTENANCE
:
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).
14
When the pumping cycle is
completed, the vacuum level should register above 16" Hg [-54 kPa] on the vacuum gauge (if
not, see V
ACUUM

DJUSTMENT
to follow).
3) After the vacuum pump stops running, leave the pads attached to the surface and interrupt
the energy flow from the battery: Disconnect the electrical connector uniting the battery to
the vacuum generating system.
Note: After the vacuum test is completed, move the valve handle to the “RELEASE” position
(power
off
) before reconnecting the battery.
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.
13
If these cleaning methods are not successful, contact Wood’s Powr-Grip or an authorized dealer for assistance.
14
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.
