Lift bar must be vertical to lift
load.
Interpreting the Warning Light and Optional Warning Buzzer
Never lift load unless warning devices turn off, because
this could result in load release and personal injury.
When the vacuum
lifter is ready to lift
the Maximum Load
Capacity, the vacuum pump and the low vacuum warning light turn off temporarily, to conserve
battery energy.
When air leaks into the vacuum system, the vacuum pump turns on and off (along with the
warning light) as necessary to maintain sufficient vacuum for lifting.
1A
Note: The low vacuum warning buzzer, if present, turns on and off together with the warning
light.
Watching Vacuum Indicators
Watch the low vacuum warning light and the vacuum
gauge (fig. 1A) throughout the entire lift.
Make sure vacuum indicators remain
completely visible.
If the warning light turns on and the vacuum gauge
shows a level less than 16" Hg [-54 kPa]:
1) Keep everyone away from a suspended load until
it can be safely lowered to a stable support.
Stay clear of any suspended load while
indicators warn of low vacuum.
2) Stop using the lifter until the cause of the vacuum loss can be identified: Conduct the
“Pad Inspection” on page 25 and perform the “Vacuum Test” on page 23.
3) Correct any faults before resuming normal operation of the lifter.
