Install the three stainless steel Azimuth spoke arms to the inner Azm bearing ring with three M6
screws. The encoder housing should be precisely placed at the Azm bearing center by making
sure the scale readings on all three AZ spoke arms are exactly the same at the edge of the Azm
inner bearing. Tighten the M6 screw and the center screw to lock the encoder housing to the Azm
spoke arms. If there are no additional holes on your Azm bearing,
you can install the AZ spoke
arms in the same three holes used by the footers, and use the same wing nuts to lock the
spoke arms.
Install the Azm encoder arm assembly by carefully inserting the encoder shaft into the center hole
of the brass encoder housing. Adjust the depth so the threaded shank of the encoder does not
touch the housing.
Tighten the Nylon setscrew on the side of the brass housing onto the
shaft .
