Wood’s Powr-Grip MRTA811LDC - Manual (Page 18)

Rev 9.0/6-12 16 MRTA8-DC: #35075
In Case of Power Failure
The lifter is equipped with a vacuum reserve tank, designed to maintain vacuum temporarily in
case of a failure at the lifter's power source.
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 or use other appropriate means to keep the load under
control at all times. Squeeze the rotation release lever to disengage the
rotation latch, and rotate the load to the desired position.
11 To stop the
load’s motion automatically at each quarter turn, simply let go of the rotation
release lever immediately before the end of the turn, 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.
11
If the load's center of gravity is not centered on the pad frame, it may be necessary to relieve pressure on the rotation latch
by applying force to the pad frame in the appropriate direction of rotation.
