Adjustment of the Dislodged Control Knob

Getting Started

Put the dislodged control knob back on.

How to Adjust

1. Detach the Belleville spring washers inside the dislodged control knob using tweezers.

2. Attach the Belleville spring washers to the axis where the control knob became dislodged.

* Be aware of the mounting orientation of the Belleville spring washers. Follow the way as illustrated in the figure.

* If the threaded axis caves in, turn the axis in the direction of the arrow.

3. Insert an Allen wrench into the hole in the center of the knob and give it about three turns counterclockwise to loosen the set screw.

* Turning it counterclockwise allows the set screw to rise a little.

4. Align the knob with the axis in the center and turn it clockwise to screw it down.

* After screwing it down to some extent, check the knob for looseness by holding it to move up and down.

5. Hand-hold the knob and fasten the set screw securely.

In Closing

After fastening the set screw, turn the knob to ensure that the axis works properly and the knob has no looseness.

* If it works loose, repeat the above procedure 1 through 5.

* If the knob feels too tight to turn, go back to the procedure 4 and turn back the knob counterclockwise lightly and then fasten the set screw again.
