Note: The vacuum pad can stain or deform load surfaces with light colors or soft coatings. The
operator should test such surfaces for detrimental effects before attaching them to the pad.

Generating Vacuum Flow
Place the power switch in the “ON” position. This engages the vacuum pump, causing air to be
drawn immediately at the vacuum pad.
WARNING: Never turn power off during operation; keep pump running while
load is attached.
The product is designed for the vacuum pump to run continuously. Placing the power switch in
the “OFF” position during product operation could result in the release of the load and possible
injury to the operator (see In Case of Power Failure to follow).
Positioning the Load on the Pad
Make certain that the contact surfaces of the load and the vacuum pad are free of any
contaminates that could prevent the pad from sealing against the load (see MAINTENANCE:
V
ACUUM

AINTENANCE
).
WARNING: Materials with rough or porous surfaces may reduce load capacity.
(see Vacuum Level with Rough or Porous Load Surfaces to follow.)
Position the load so that its center of gravity is centered on the vacuum pad, because off-center
loading can cause the load to rotate unexpectedly. Make sure that the load's contact surface
covers the entire face of the pad.
Note: If a hard object has been resting against the pad, it may be slightly distorted. Although
initially it may be difficult to seal the pad against a load, this condition should correct itself with
continued use.
Reading the Vacuum Gauge
The vacuum gauge indicates the current vacuum level in the product’s vacuum system. The
green range indicates vacuum levels sufficient for supporting the maximum load weight, whereas
the red range indicates vacuum levels that are not sufficient for supporting the maximum load
weight. The gauge needle should show a sudden surge in vacuum as the vacuum pad seals
against the load. If it takes more than 5 seconds for the vacuum level to reach 5" Hg [-17 kPa],
apply firm pressure at the center of the load until the pad seals completely.
