Hi Crizal:

That’s exactly the model I have. I got it from my father in law about 15 years ago and totally restored it a couple months ago. I took many pictures as I worked on it. I use it all the time and am very happy with it.

Here’s the user manual:

Your column to base tightness is set by the column tube key. That procedure is shown on page 9 of the user manual. They show it being pushed it with your finger. That will not work. Instead put a clamp on it as shown in the picture below. Once you clamp it tight, tighten the set screw with an allen wrench to hold it in place. If you get it too tight, it will be hard to crank the column up and down. Too loose and the column will rotate in the base.

Below are some pictures of the column tube key removed from the column. It’s got a wedge shape that meshes with the groove in the column.

Note: This adjustment is for getting the column not to rotate within the base. If your trouble is with the arm rotating about the column, that’s a different adjustment.

regards, Kerry
