Switch on the lifting device.

Place the lifting device on a sheet metal plate or similar and suck in the plate.

Attention: Only suck in the plate, do not lift it! The plate can come loose during
the inspection and fall down.
If the vacuum is built up, create a leak at the sealing lip of the suction plate. The
vacuum at the manometer decreases. When the pointer reaches the red danger
zone, the warning device must give an alarm.
To ensure that the warning device operates safely, always test the device for
function before each use.
1. The function test is performed at ambient temperature without an attached
workpiece
(manometer shows 0 mbar).
2. Press button for approx. 1 second
3. Evaluate the signal tone:
Signal tone approx. 2 sec. → Function test successful. → Warning device ready for
operation.
Very short signal tone (10 ms) → Battery voltage too low → Replace the batteries or
sensor faulty → Replace entire warning device
No signal tone at all → Batteries dead → Replace the batteries oder Electronics faulty
→ Replace entire warning device.
Note: A short signal tone of 10 ms is necessary for technical reasons to test the voltage
of the batteries.
(For further information see separate operating instructions in the appendix)
Check all vacuum hoses and clamps for proper mounting and tighten the clamps if
necessary.
See "Testing for Leaks"" in chapter "Maintenance"
Correct any faults before using the device. If faults occur during operation, switch
