If the lifter is equipped with a Remote Control System, there are 2 enable switches: a rotary
switch on the radio transmitter, as well as a push-button switch on the lifter (see OPERATING
FEATURES). To actuate the enable switch on the lifter, simply press the enable button. To
actuate the enable switch on the optional radio transmitter, rotate the transmitter power/enable
switch beyond the “ON” position to the “START” position. 13
A strobe light flashes as long as the operator is actuating the enable or release controls. This
serves to show the operator when signals are being transmitted successfully from a remote
location and also to warn other personnel that the operator is suspending the apply function.

WARNING: Load must be fully supported before releasing vacuum pads.
Make sure the load is at rest and fully supported. Then turn the apply/release switch on the
movable control pendant to the “RELEASE” position (counter-clockwise) to force air into the
vacuum pads, quickly breaking the vacuum seal. Continue to hold the apply/release switch in
this position until the pads disengage completely from the load.
When the apply/release switch is no longer held in the “RELEASE” position, it automatically
returns to the neutral position (stand-by mode). Do not turn the apply/release switch to the
“APPLY” position until the pads are contacting the next load to be lifted. This conserves battery
energy and reduces the time required to apply the pads to the load, by preventing the vacuum
reserve tank from losing its vacuum.
Alternatively, if the lifter is equipped with a Remote Control System, actuate and hold the enable
switch on the radio transmitter or the enable button on the lifter, causing the strobe light to flash
(see A

preceding). While holding the enable
switch, press a release button (on the optional transmitter or on the lifter) to force air into the
vacuum pads, quickly breaking the vacuum seal. Continue to hold both controls until the vacuum
pads disengage completely from the load.
WARNING: If vacuum pads do not disengage completely, do not attempt to
move the lifter or load.
The operator must never attempt to move the lifter or load until the vacuum pads are completely
disengaged, as this could cause an unexpected load release and potential injury to the operator
or others. If the vacuum pads do not disengage completely on the first attempt, repeat the
release process. If the load cannot be successfully released for any reason, reapply the vacuum
pads to the load as previously directed (see T

preceding) prior to
moving the lifter or load.
After the load is successfully released, the lifter will automatically activate the stand-by mode to
conserve the battery energy until the lifter is ready to lift another load. Once the stand-by mode
is activated, only the blue power light remains illuminated.
Prior to lifting another load, perform the Every-Lift Inspection as directed in MAINTENANCE:
