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 has
sufficient vacuum to lift the
Maximum Load Capacity, the vacuum lift
light turns on automatically.
Watching Vacuum Indicators
1B
Make sure
all vacuum
indicators remain
completely visible.
Watch the vacuum lift light and the vacuum gauge (fig.
1B) throughout the entire lift.
The vacuum pump runs continuously to maintain
sufficient vacuum for lifting the maximum load weight.
However, if the lift light turns off and the vacuum gauge
shows a level less than 16" Hg [-54 kPa]:
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 29 and perform the “Vacuum Test” on page 27.
3) Correct any faults before resuming normal operation of the lifter.
Controlling the Lifter and Load
1A
When the lifter is ready, use the hoisting equipment to raise
the lifter and load as needed.
Use a control handle (circled in fig. 1A) to keep the lifter and
load in the required position.
Once there is enough clearance, you may move the load as
required.
