Lift bar must be vertical to lift
load.
Interpreting the Lift Light
Never lift load unless lift
light is illuminated,
because premature lifting could
result in load release and
personal injury.
When the vacuum lifter is ready to lift
the Maximum Load Capacity, the
vacuum lift light turns
on
automatically and
the vacuum pump turns
off
temporarily, to
conserve battery energy.
Watching Vacuum Indicators
1A
Watch the vacuum lift light and both vacuum gauges
throughout the entire lift (fig. 1A).
Make sure all vacuum indicators remain
completely visible.
The vacuum pump turns on and off to overcome any
leakage. However, if the leak rate is greater than
normal, the notification buzzer chirps and the LCD
screen displays the message “Vacuum decrease on
circuit #”, along with a diagnostic code (see
1
Such leaks can cause the
battery to be discharged more quickly.
If the vacuum pump is unable to overcome leakage
, the notification buzzer sounds
continuously, the lift light turns off, and the LCD screen displays the message “INSUFFICIENT
VACUUM!”, along with a diagnostic code (see
). If this happens:
1)
Stay clear of any suspended load while
indicators warn of low vacuum.
Keep everyone away from a
suspended load until it can be safely
lowered to a stable support.
