5. Do both of the following when you place the yoke on Cyberlight:
• Make sure the U-shape of the yoke is opposite the center access door, as shown in Figure
1-9.
• Align the bottom holes on the yoke with the yoke pivot hole labeled in Figure 1-9.
6. Insert the two 5/16 inch allen bolts through the round holes in each side of the yoke, and
through the holes in the side of the Cyberlight. Tighten them using your fingers or an allen
wrench.
7. Place a locknut on the end of each 5/16 inch allen bolt. You can use either a 9/16 inch socket
wrench or a 9/16 inch wrench to turn the nut. Tighten the nut until so you are still able to pivot
the fixture.
8. Position the yoke as desired, using the deviation degree markings on the yoke for exact
positioning. When you have placed the fixture correctly, firmly tighten the T-handles.
