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.

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
upwards, as well as more horizontal space when tilted
downwards. 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 upwards, push the toggle
towards the vacuum release button (also on control pendant); to
tilt the load downwards, push the toggle away from the release
button. Releasing the toggle switch locks the load in any position
within the 90° range of tilt movement.

WARNING: Load must be fully supported before releasing vacuum pads.
When the load is at rest and fully supported, push the vacuum release button on the movable
control pendant to force air into the vacuum pads, quickly breaking the vacuum seal. After the
pads have disengaged completely from the load, move the lifter away. Continue to hold the
release button until the pads are well away from the load; otherwise, the lifter would reattach
itself to the load.
