CAUTION: Examine each air filter regularly, and empty when necessary.
The lifter is equipped with one or more air filters to help protect the vacuum system from
contaminants. In order for a filter to function, the operator must empty the filter bowl before
enough liquid accumulates to contact any portion of the filter element (see MAINTENANCE: A

Positioning the Lifter on the Load
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
P
AD
M
AINTENANCE
). 4
WARNING: To avoid accidental load release, always center lifter’s vacuum pad
on load.
Center the lifter’s vacuum pad to within 2" [5 cm] of the load center, since off-center loading
could result in a load release and possible injury to the operator, and it may also damage the
lifter.
5 Make sure that the vacuum pad will fit entirely on the load’s contact surface (see
SPECIFICATIONS: Pad Spread). Then lower the lifter onto the load until the pad is touching the
contact surface.
Sealing the Pad against the Load
Firm pressure at the center of the lifter
helps the vacuum pad begin to seal
against the load. Pull the valve handle
outward until it latches securely in the
“APPLY” position (power on), as shown.
This energizes the vacuum pump, causing
air to be drawn at the pad immediately.
The red low vacuum warning light also
turns on and remains illuminated until the lifter attains sufficient vacuum to lift the maximum
load weight (see T
O
L
IFT AND
M
OVE THE
L
OAD
: Load Capacity and the Warning Light to follow). The
valve handle must remain in the “APPLY” position throughout the entire lift.
WARNING: Keep valve handle latched securely in “APPLY” position throughout
lift.
Note: If a vacuum pad has been lying against a hard object (as during shipping), it may be
slightly distorted. Although initially it may be difficult to apply the pad to a load, this condition
should correct itself with continued use.

Since oil damages the rubber in a standard pad, the load surface must be free of oil unless the lifter is equipped with an
optional chemical-resistant pad, which may be used on oily surfaces.
5
The lifter is designed to handle the maximum load weight (see SPECIFICATIONS: Maximum Load Capacity) when the load’s
center of gravity is positioned within 2" [5 cm] of the vacuum pad’s center point. Occasional loading deviations are permissible,
provided that the operator can maintain control of the load at all times and that the load weight is low enough to avoid damaging
the lifter.
