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 32 and perform the “Vacuum Test” on page 30.
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.
In Case of a Power Failure
In the event of a battery failure or electrical system failure, the notification buzzer will sound
continuously.
Although the vacuum reserve tanks are designed to support the load for at least 5 minutes
without power, this depends on many factors, including the “L
OAD
C
HARACTERISTICS
” on page 12
and the condition of vacuum pads (see “V
ACUUM

” on page 32).
Stay clear of any suspended
load during power failure.
If a power failure occurs, keep everyone away from a
suspended load until it can be lowered safely to a stable
support. Correct any faults before resuming normal
operation of the lifter.
