12. After cleaning, apply a thin film of grease on to the cone of the collet
chuck. This improves the lubrication and increases the clamping
force of the collet chuck.
13. Screw the covers back onto the mandrel. Tighten until the bolting tool
clicks. This means that the intended torque has been achieved.
14. Pull the suction guard over the mandrel.
15. Confirm completion of the maintenance in the software.

During longer downtimes
➢ Turn the shaft of the HF-mandrel at least 10 times by hand every 3
months.
The downtimes of the machine are automatically saved.
In the case of longer downtimes, an automatic run-in time of the mandrel
occurs. This run-in time occurs after switching on the machine and can
take several minutes to complete, depending on the downtime.
