Release the brake lever

Loosen the outer nut, A, a few turns. 

(No need to remove all the way)

Tighten inner nut, B, one revolution

Return brake lever to the locked position and test to see if 

tabletop holds firmly in desired position. If not, release brake 

and tighten nut B additional revolution(s). This procedure will 

take some trial and error.

Once desired brake-locking strength is reached, tighten nut 

A firmly up against nut B. Use care not to rotate nut B while 

doing so.

The brake lever should hold the tabletop firmly at any height 

or tilt position. If it fails to do so, follow this procedure to 

increase the braking strength. Please refer to 

Figure 12
