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 “I
NTELLI
-G
RIP
® D
IAGNOSTIC
C
ODES
” on
page 38).

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 “I
NTELLI
-G
RIP
® D
IAGNOSTIC
C
ODES
” on page 38). 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.
2) Stop using the lifter until the cause of the vacuum loss can be identified: Conduct the
“Pad Inspection” on page 35 and perform the “Vacuum Test” on page 33.
3) Correct any faults before resuming normal operation of the lifter.
1..... Automatic leak detection is not a substitute for performing the “Vacuum Test” on page 33, required by the “I
NSPECTION
S
CHEDULE
” on page 31
and “T
ESTING
” on page 32. Sensitivity of leak detection can be adjusted (see “INTELLI-GRIP® OPERATOR MENUS” in SERVICE MANUAL ).
