2. Insert the clamps into the clamping slots.
3. Mount the vacuum plate on the machine table.
» Vacuum plate mechanically mounted.
6.2. INSTALLATION OF THE COMPRESSED AIR
NOTICE
Damage due to liquid taken up by suction
Liquids that penetrate between the clamping face and workpiece seating face can
damage the Venturi vacuum pump and reduce the coefficient of friction of the work-
piece.
»
Check that the workpiece is securely seated.
1. Connect a compressed air hose with a shut-off valve (included in the scope of
supply) to the screwed connector.
2. Connect the other end of the compressed air hose to the 7.2 mm hose coupling
adaptor.
3. Connect the 7.2 mm hose coupling adaptor to the compressed air supply.
» The compressed air is now installed.
6.3. INSTALLATION OF THE VACUUM
NOTICE
Damage due to liquid taken up by suction
Liquids that penetrate between the clamping face and workpiece seating face can
damage the vacuum pump and reduce the coefficient of friction of the workpiece.
