The movable control pendant is not intended to be disconnected during lifter operation.
Disconnecting the control pendant is likely to result in a load release and injury to the operator or
others nearby.
Turn the apply/release switch on the movable control pendant to the “APPLY” position
(clockwise). This energizes the vacuum pumps, causing vacuum to be drawn immediately at the
vacuum pads. Press the lifter onto the load until all the pads seal against it. The apply/release
switch must remain in the “APPLY” position throughout the entire lift.
WARNING: Keep apply/release switch in “APPLY” position throughout lift.
Note: If a vacuum pad has been lying against a hard object (as during shipping), it may be
slightly distorted. Although initially it may be difficult to apply the pad to a load, this condition
should correct itself with continued use.
Reading the Vacuum Gauges
The lifter is equipped with 3 vacuum gauges: 2
small vacuum gauges are located on the pad
frame, to indicate the current vacuum level in each circuit of the lifter's vacuum system. A third,
large vacuum gauge is located on the lift bar. So long as the air filters on the pad frame are
maintained properly (see B
EFORE
U
SING THE
L
IFTER
: Performing Inspections and Tests preceding),
the large vacuum gauge indicates the lower of the vacuum levels existing in the 2 circuits.
Each vacuum gauge registers vacuum in the same way: The
green range indicates vacuum
levels sufficient for lifting the maximum load weight, whereas the
red range indicates vacuum
levels that are
not
sufficient for lifting the maximum load weight. The gauge needle should
show a sudden surge in vacuum as the vacuum pads seal against the load. If it takes more than
5 seconds for the vacuum level to reach 5" Hg [-17 kPa] on a vacuum gauge, press on any pad
that has not yet sealed.
