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.

Positioning the Lift Bar
WARNING: Lift bar must be oriented vertically to lift load.
Never lift the load from a flat position with the lift bar latched parallel to
the load. Always disengage the tilt latch (see T

and raise the lift bar to a vertical orientation before attempting to lift.
About Red-Line Indicators
Each hand cup is equipped with a red-line vacuum indicator. When the red-line indicators are
hidden on all the hand cups, the lifter is ready to lift the load.
WARNING: Never attempt to lift load when any red-line indicator is visible.
Do not attempt to lift a load while any red-line indicator is visible; such an attempt could result in
a load release and possible injury to the operator.
Monitoring Vacuum Indicators
All hand cups must remain visible to the operator, so that the red-line vacuum indicators can be
monitored throughout the entire lift. If any of the hand cups experiences leakage, its red-line
indicator becomes visible, to signal the reduction in vacuum to the operator.
WARNING: Monitor red-line indicators throughout entire lift; never leave
suspended loads unattended.
Check all red-line indicators frequently to make sure the vacuum pads are attached securely. If a
red-line indicator becomes visible while you are lifting a load, move away and stay clear of the
load until it can be lowered to the ground or a stable support.
WARNING: Stay clear of suspended load while any red-line indicator is visible.
Discontinue lifter use until the cause of the vacuum loss can be determined. If it is caused by
contamination, thoroughly clean the contact surfaces of the load and the vacuum pads (see

: Cleaning), and reapply the lifter to the load. If a red-
line indicator remains visible when the lifter is attached to clean, smooth, nonporous materials,
the hand cup requires service or repair. Inspect the vacuum pad for damage (see
MAINTENANCE: V
ACUUM

: Inspection) and consult the hand cup instructions for
service directions. Perform inspection and maintenance as needed to identify and correct any
deficiency before resuming normal operation of the lifter.
Controlling the Lifter and Load
When the red-line vacuum indicators show that the lifter is ready, use the hoisting equipment to
raise the lifter and load as needed to clear any obstacles in their path. Use the control handle
and/or the hand cup handles to keep the lifter and load in the desired orientation while they are
suspended from the crane. Once sufficient clearance is established, the load can be rotated or
tilted as desired (see T
