Installation 3-9 6. Firmly press the neighboring sections together while tightening the two M3 x 20 mm screws through each tie bar into the flanges of the sections. Alternately tighten the screws into the flanges and those into the sides of the extrusions to ensure that each tie bar is drawn into the corner of the extrusion. IMPORTANT: Be careful not to overtighten these screws. 7. Inspect the joint to see that the sections are well aligned, with minimal irregularities and gaps. 8. Repeat steps 6, 7, and 8 for each pair of sections. It may be necessary to use suitable blocks to support the row of sections so that neither the motor housing nor the bottom flange of the base section touches the work surface while you are connecting the motor drive section. 9. Center one of the support bars across the rear of the motor drive section over the holes on the rear surface of that section. 10. Insert two M4 x 20 Phillips sems screws through the holes in the support brace into the holes in the motor drive section, and tighten. 11. Go to the next section, Installing the Belt. Installing the Belt Refer to Figures 3-5 through 3-9. 1. Turn the assembled Pass-Thru mechanism over so that the motor points upward. 2. Referring to Figure 3-6, locate the tensioner ramp in the base section. Compress the spring until the hole in the tensioner ramp is aligned with a hole in the base section. Insert an 0.050" Allen wrench or a paper clip through the holes. This sets the idler pulley for zero belt tension.
