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.
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. Maintain a firm grip
on the pad frame to keep the load under control at all times. 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.
