DANGER
Danger from burners and hot coupling parts
Risk of injury due to burners and hot surfaces. Burners or hot coupling parts can lead to an
explosion in potentially explosive atmospheres.
• Wear suitable protective equipment (gloves, safety glasses).
• Ensure that the area is not at risk of explosion.
Procedure
1. Secure the coupling parts to prevent them from falling.
2. Remove the axial locking elements (set screw, end plate).
3. Use a suitable pulling fixture.
4. Heat up the coupling part 1 (1), 2 (2), 11 (11), 32 (32) or the hub carrier part (120) using
a burner above the parallel keyway along its length to maximum 80°C.
5. Pull off the coupling part or hub carrier part. Use suitable lifting gear when doing this.
