6. Check that the workpiece is securely seated.
» The workpiece is now clamped.
7.2. REMOVING THE WORKPIECE
1. Before removal of the workpiece, clean the vacuum plate under vacuum using an
industrial vacuum cleaner.
Fault
Operating vacuum not achieved or is too
low, and the compressed air unit is running
Vacuum plate changed over to vacuum
connection: Operating vacuum not
achieved or is too low, and the vacuum
pump is running
The clamping face of the vacuum plate is
damaged
The restraining force is insufficient to ma-
chine the workpiece
10. Cleaning
Clean with a cloth or compressed air.
Do not use any corrosive cleaning agent.
11. Storage
Store in an enclosed dry room.
Do not store close to corrosive or aggressive chemical substances, solvents, moisture
or dirt.
Protect against direct sunlight.
Store at temperatures between +15° C and +35 °C.
Relative atmospheric humidity max. 60%
12. Spare parts
Use only original spare parts and wearing parts.
Use only a Ø 4 mm sealing cord.
13. Disposal
Comply with the national and regional environmental protection and disposal regu-
lations for correct disposal or recycling. Segregate items into metals, non-metals,
