4.6 Special Hazards

●
The operating range have to be covered for unauthorized persons, especially children.
●
The workplace have to be sufficiently illuminated.
Attention
●
Take care handling wet, dirty and not solidified components.
●
The working with the vacuum lifting device in case of atmospheric editions under 37,5° F is
forbidden!
Because the goods could be fall down caused by dampness or freezing.
●
Take care in case of thunderstorm!
Prohibition
●
Since the load is held on the suction plates of the unit by a vacuum, it will fall off as soon as
this vacuum is lost.
●
This can happen if the vacuum generator fails. An integrated vacuum reservoir maintains the
vacuum for a short safety period whose duration depends on the porosity of the work piece
surface.
●
If the vacuum generator fails, lower the load immediately if this is possible. Otherwise, leave
the danger area below the load immediately.
Danger
●
The unit draws in large amounts of air and hair and items of clothing can be drawn into the
air inlet. Do not look into the air inlet when the unit is running: it is even possible for your
eyes to be drawn into the air inlet.
Danger
4.7

Workplaces

●
The workplace of the operator is in front of the operator handle.
●
The operator must stand so that he can see the vacuum gauge at all times.

4.8 Behaviour in Emergencies

An emergency situation exists when:
●
power suddenly fails (unit switches off),
●
the vacuum drops below -0.42 bar (red area of the pressure gauge).
●
In such cases, lower the load immediately if this is possible. Otherwise, leave the danger area
below the load immediately. The load will be dropped from the lifting device!
Danger

4.9 Testing the Safety Devices

The lifting device is equipped with following safety equipment:
●
pressure gauge (with red danger zone display)
●
alarm signal (audio)
Check this equipment
Attention
●
at the beginning of each shift (when operating in shifts),
●
once a week (when operating continually).
●
Correct faults before operating the device. If faults occur during operation, switch the device off
and correct the faults before continuing work with the device.
