Stop!
Do not dismantle new shrink disc.
Never tighten clamping screws before the machine shaft is pushed in.
Otherwise the hollow shaft may be deformed plastically. Protect the shrink
disc against contact while in operation by appropriate measures (e.g. cover).
Degrease hollow shaft bore and machine shaft!
