IV. Attaching the coupler bars
Install the right and left coupler bars (#5R & 5L) to the main frame (#1) using the connection shaft
(#14). Set the coupler bars aside for a moment. Take off, only from one end of the connection shaft,
the 3/8” x 20 side screw (#28), 3/8” spring washer (#27), and D clip washer (#26). Be aware that the clip
washer is designed to only go on one way. Watch how it comes off and take note of how it fits back on.
Slide the connection shaft (#14) through the short connection tube from left to right. Slide the
connection shaft through the tube in the left coupler bar (#5L). Replace the D clip washer (#26), the
3/8” spring washer (#27) and the 3/8” x 20 side screw (#28) on the left side and hand tighten. Next,
repeat the same steps on the right side. Take two small Allen wrenches and insert one in the center
of each side screw. Only tighten one side at a time and let the opposite Allen Wrench hold the other
bolt in place. Once that side is tight, tighten the other side.
