Interpreting the Lift Light

Never lift load unless lift
light is illuminated,

because premature lifting could

result in load release and
personal injury.

When vacuum is sufficient to lift the
Maximum Load Capacity, the vacuum

lift light turns

automatically and the

vacuum pump turns

off

temporarily, to

conserve battery energy.

Monitoring Vacuum Indicators

Monitor 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

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:

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.

2) Stop using the lifter until the cause of the vacuum loss can be identified: Conduct the

“Pad Inspection”

and perform the

“Vacuum Test”

3) Correct any faults before resuming normal operation of the lifter.

1..... Automatic leak detection is

not

a substitute for performing the

, required by the

. Sensitivity

of leak detection can be adjusted (see “INTELLI-GRIP® OPERATOR MENUS” in
