Sealing the Pads against the Load
The apply/release switch is located on the movable control pendant. The movable control
pendant allows the vacuum controls to be moved away from the lifter, so that the operator can
control airflow at a distance equal to the length of the extension cord.
WARNING: Do not disconnect control pendant during lifter operation.
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 to the “apply” ( ) position (clockwise) to make sure the apply
function is activated.
WARNING: Keep apply/ release switch in “APPLY” position throughout lift.
Alternatively, if the lifter is equipped with a Remote Control System, press an apply button ( )
on either the radio transmitter or the lifter, to make sure the apply function is activated.
This energizes the vacuum pumps, causing air to be drawn immediately at the vacuum pads.
The low vacuum warning buzzer also sounds an alarm until the lifter attains sufficient vacuum to
lift the maximum load weight (see T

follow). Press the lifter onto the load until all the pads seal against it. The lifter must remain in
the apply mode throughout the entire 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 Gauge
The vacuum gauge indicates the current vacuum level in the lifter’s vacuum system. 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], press on any pad
that has not yet sealed.
