Controlling the Lifter and Load
When 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 handles or other
appropriate means to keep the lifter and load in the desired orientation while they are suspended
from the crane.
WARNING: When lifter is positioned above center, tilt latches must be locked
out before lifting load.
If the lifter is positioned
above center
on a load encountered in the flat orientation, the load
automatically tilts to the upright position when lifted (see T
O
T
ILT THE
L
OAD
: Tilting Loads
Positioned Above Center to follow). In this case, failure to lock out the tilt latches could result in
an unexpected load release or damage to the lifter. If the load is positioned
on center
, the load
can be tilted as desired once sufficient clearance is established (see T

: Tilting
Loads Positioned On Center
to follow).
In Case of Power Failure
The lifter is equipped with 2 vacuum reserve tanks, 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.
