ble)
Use only “function” button and “power” button to power
down lifter. Lifter cannot be powered down while any
other button is pressed.
U03
“Timed release: # seconds”
1 chirp per
button press
on
Timed release function is activated for number of seconds
shown (see
). Press
“function” button to cancel action or press “attach” button
to override. No corrective action is necessary.
U04
“Also hold [Fn] to release”
(none)
(none)
Hold “function” button and “release” button at same time
to release load.
U06
“Let go of [Fn] and Release”
(none)
on
Use only “attach” button to attach load. While “attach”
button is pressed, lifter does not respond to pressing any
other button. Release all buttons and press button(s) again
to activate different function.
U08
“Menu not available in Attach”
(none)
(none)
Operator Menus cannot be accessed while lifter is
attached to load.
U09
“Counterweight not retracted”
continuous
on
“Release” function is prevented because counterweight is
not positioned correctly. Reposition counterweight as
directed (see Counter-Balancer
OPERATING
INSTRUCTIONS,
if necessary).
U10
“Use POWER button for Live
Stats”
(none)
(none)
“Power” button (not “function” button) is now used to
access Live Stats. No corrective action is necessary.

Immediately lower load onto stable support until adequate
vacuum can be obtained. Check load and vacuum pads for
damage. Consult relevant topics in “ASSEMBLY”,
“OPERATION”, “INSPECTIONS AND TESTS”, and
“MAINTENANCE”.

V004
“INSUFFICIENT VACUUM #!”
(# indicates relevant vacuum
circuit)
continuous
on
Immediately lower load onto stable support until adequate
vacuum can be obtained in vacuum circuit indicated. Check
load and vacuum pads for damage. Consult relevant topics
in “ASSEMBLY”, “OPERATION”, “INSPECTIONS AND TESTS”,
and “MAINTENANCE”.
This code can be activated in connection with Code N00.

V014
V015
“Vacuum decrease on circuit #”
(# indicates relevant vacuum
circuit)
3 chirps
(none)
Vacuum decreased at greater rate than expected in
circuit(s) indicated. Possible causes include bouncing or
landing load, as well as use on rough or porous loads and
other sources of vacuum leaks. Consult relevant topics in
“ASSEMBLY”, “OPERATION”, “INSPECTIONS AND TESTS”,
and “MAINTENANCE” to eliminate leaks when possible.
When appropriate, you can also adjust sensitivity to
vacuum level reductions (see “INTELLI-GRIP

“Vacuum not increasing
normally”
1 chirp every
2 seconds
on
Although lifter began to attach, vacuum level did not
increase at normal rate. Make sure all vacuum pads seal
