Information
The handle in the handwheels GN 520.4 is locked in a conical bore in the operating position.
For reversal, it must first be pulled from the cone in axial direction.
A pressure spring holds the handle in both positions. When swung out, it automatically engages again.
This standard replaces the previous handwheels GN 520.3.
