full range of motion after tightening the nut. Do not over tighten the nut.

Steps (4) and (5) apply to installations with an Adjust -a-Goal. Refer to instructions
received with AAG, for mounting board to AAG only. If you did not receive instructions
please contact factory. If your installation does not have an Adjust -a-Goal, please skip to
step ( 6).

prior to mounting the board.
5) While assembling the AAG on the ground, the AAG mounting frame can be installed on
the ends of the extension tu bes. Utilize eight of the 3/8” -16 x 1 1/4" hex head bolts with
washers and whiz -lock nuts to attach the support plates of the frame to the end brackets
