Controlling the Lifter and Load
When the 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 to keep the lifter and load in the desired
orientation while they are suspended from the crane, as
shown. Once sufficient clearance is established, the load
can be rotated or tilted as desired (see T

In Case of Power Failure
In the case of a power failure (ie, in battery), 2 vacuum reserve tanks are designed to maintain
vacuum temporarily and a power loss warning buzzer will sound an alarm to alert the operator of
potential danger.
Stay clear of any suspended load in the event of a power failure.
Although the lifter is designed to support the load for at least 5 minutes without power, this
depends on many factors (see INTENDED USE: L

). If a power failure occurs, keep all personnel clear of the
suspended load until it can safely be placed on the ground or a stable support. Correct any
deficiency before resuming normal operation of the lifter.
