Fitting

• Remove the preservative agent from the hollow shaft and the machine shaft with a suitable cleaning
agent (such as benzine).
Do not allow the cleaning agent (e.g. benzine) to contact the shaft­sealing rings.
Ensure adequate ventilation. Do not smoke!
Danger of explosion!
• Check the hollow and machine shafts to ensure that seats and edges are not damaged. If necessary,
rework the parts with a suitable tool and clean them again.
Coat with a suitable lubricant to prevent frictional corrosion of the contact surfaces.
