Behaviour in Emergencies
An emergency situation exists when
•
power suddenly fails (device switches off),
•
the vacuum pressure drops below -0.6 bar to the red section on the scale of the vacuum gauge.
Lower the load immediately if possible. If this is not possible, immediately leave the dangerous area near
the load, since it will be dropped from the device.

Checking the Safety Devices
The lifting device is equipped with
following safety devices:
•
vacuum gauge with red danger zone
•
warning device, audible (optional)
Check these devices at the beginning of each shift (when operating in shifts) or once
a week (when operating continually).
Checking the Vacuum Gauge and the
Warning Device
To ensure safe operation of the device, a battery test of the warning device must be
carried out before each use of the device.
Warning device monitors the operating vacuum and power failure
Switch on the lifting device.
Place the lifting device on a stone slab or similar material and apply vacuum.
Caution
: Simply apply vacuum to attach the suction pads to the stone slab. Do not lift
the stone slab, since it may be dropped during the test!
When the vacuum has built up, lift the edge of a suction pad to create a leak.
The reading on the vacuum gauge decreases. When the vacuum drops below red
danger zone, the warning device must sound.
Checking the Vacuum Hoses and
Hose Clamps:
Check all vacuum hoses and clamps for proper mounting and tighten the clamps if
necessary.
Checking the Vacuum Reservoir
See “Testing for Leaks"“ in chapter “Maintenance“
Correct any faults before using the device. If faults occur during operation, switch
the device off and correct the faults before continuing work with the device.
