In Case of Power Failure
The lifter is equipped with a vacuum reserve tank, designed to maintain vacuum temporarily in
case of a power failure (ie, in battery).
WARNING: 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, including the condition of the load and the lifter’s vacuum system (see

). 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.

WARNING: Make sure load is positioned correctly on lifter (see T

unbalanced loads may rotate unexpectedly when latch is
disengaged.
Remember that the load is longer in its diagonal dimensions than in its side
dimensions. Make sure there is sufficient clearance for the load to rotate
without contacting the operator or any nearby objects. Keep the load under
control at all times, using hand cups or other appropriate means. Pull the
rotation release lever to disengage the rotation latch, and rotate the load to
the desired position. To stop the load’s motion automatically at each quarter
turn, simply let go of the rotation release lever immediately after initiating the
rotation, so that the rotation latch engages at the next stop. Whenever
rotation is not required, keep the rotation latch engaged, to prevent
accidental damage to the load and possible injury to the operator.

CAUTION: Make sure load is positioned correctly on lifter (see T

); unbalanced
loads may damage lifter.
Remember that the load requires more vertical space when tilted
to the upright position, as well as more horizontal space when
tilted to the flat position. Make sure there is sufficient clearance
for the load to tilt without contacting the operator or any nearby
objects. The tilt toggle switch on the movable control pendant
controls the powered tilt motion: To tilt the load towards the flat
position, push the toggle up; to tilt the load towards the upright
position, push the toggle down. Releasing the toggle switch locks
the load in any position within the 90° range of tilt movement.
