11. Slide the pulley guard into the rail. Position the belt through the alignment slots of the pulley guard. Insert the two pulley guard screws and tighten. The screws should align with the clearance holes on the rail coupler. Fig. 9

12. Place the belt into the pulley and align the pulley with the pin hole in the pulley holder. Insert the pin from underneath. It is important that the pin be inserted from the bottom as shown. Fig. 10

13. Slide the pulley assembly into the rail until it hooks onto the edges of the rail end. Check to make sure both sides of the pulley assembly are hooked on the rail end. The holes in the ends of the pulley assembly should match up with the mounting holes at the end of the rail. Important: confirm the pulley pin is still in place. Fig. 10-11

14. On the other end of the rail, slide the drive sprocket assembly to adjust its position until the tabs rest in the slots in the rail end. Insert two mounting screws and tighten with a 1/4” wrench or socket. Fig. 12.
Note: This is also illustrated in step 1G on the assembly & installation poster.

15. On the door end (pulley), tension the belt by tightening the adjustment nut on the pulley assembly until the belt does not ride on the rail (approximately 1/8” off the rail. Fig. 11
Note: This is also illustrated in step 2 on the assembly & installation poster.
