THE FRICTION BRAKE is a hex head nylon screw (see Figure 3, Item 4) which bears against
the slide rod. Tightening the screw applies tension and loosening the screw relieves tension. A spotlight
operated at an extreme down angle will require more brake tension than one operated at a more level angle.
Furthermore, the preferred degree of tension may vary between individual operators. Secure the lock nut after
setting the desired brake tension; re-install the lens mechanism housing and the color boomerang.
