11 Configuration with Vacuum Clamping Unit
The pre-configured model HS 300 LARGE | VAKUUM (Art.-No. 191.109.00) is equipped with a vacuum clamping
device. This allows workpieces to be fixed quickly and securely. The heart of the system is the electric vacuum
pump with vacuum tank and automatic switch-off, which is integrated in the bottom frame of the lift table. For
reliable and safe operation, the vacuum pump is supplemented with a foot switch, which is used to unclamp the
suctioned workpieces and which is slidably mounted on the bottom frame.
Included are two foldable support brackets, attached to the base frame, for placing large panels.
The vacuum pump is an electrically operated auxiliary device.
•
The vacuum pump must not be operated on wet or damp ground.
•
There is a risk of short circuit with increased risk of injury!
•
Maintenance and repair work on the vacuum pump may only be carried out by authorised
electricians in accordance with the electrical regulations.
•
If the connection plug is damaged or the insulation is defective, switch off the vacuum pump
immediately and have it repaired.
•
In the event of a power failure or failure of the vacuum pump, there is a risk of workpieces
falling down. Therefore, generally wear safety shoes with steel toecaps.
•
Caution: Danger of tripping! Lay the power supply cables and vacuum hoses so that they do
not pose a trip hazard and mark them with black and yellow marking tape if necessary.
Clamping the workpiece can be done in two different ways:
Figure 9: Vacuum clamping unit Figure 10: Vacuum suction cups Figure 11: Universal clamping plates
1. Via the vacuum clamping unit installed on the pre-configured model
with rotary axis and quick clamping system. Included in the clamping
unit are 1 round (Ø 100 mm) and 1 oval (300 x 100 mm) vacuum cup
(interchangeable). Further accessories see

17.2.
2. For hole grid table tops via op-
tional vacuum universal clamp-
ing plates made of aluminium
(flat or swivelling).
Risk of injury due to high negative pressure and volume flow! Items of clothing, hair as well as
skin and body parts can be sucked in and cause injuries.
•
Wear a hair net, protective goggles and close-fitting clothing.
•
Do not look or reach into the suction port when the pump is switched on.
•
Keep the suction port away from body parts and orifices.

The penetration of liquids (e.g. coolants or lubricants) can damage the vacuum pump and reduce
the adhesion of the workpiece. If necessary, connect a liquid separator between the pump and
the clamping device and make sure that the workpiece is firmly seated.
11.1 Switching on the Vacuum Pump
Figure 12: Vacuum main switch
Before starting up, make sure that all vacuum hoses between vacuum
pump, foot switch and clamping device are correctly connected and that
the vacuum clamping unit is properly fixed to the lift table. The vacuum
pump can then be switched on:
•
Plug the earthed plug into a power socket (230 VAC)
•
Switch on the vacuum pump with the switch (S) on the earthed plug
