Make sure the Az/El cap mount screw holes are properly aligned with the holes in the antenna reflector. The arrow on the Az/El labeled TOP should point to the top of the antenna reflector. Make sure the reflector is oriented so the section with a hole in its rim is on the bottom.

6.Use a 7/16-in. socket or open-end wrench to install the four 5/16-in. self-tapping screws and flat washers in the holes. Turn each screw clockwise until contact is made with the mount surface. Then use a torque wrench with 1/2-in. socket to tighten them to 10 ft-lbf. Do not overtighten.
