Installing the Belt
Do these steps to install the belt.
1. Turn the assembled mechanism over so that the motor points upward.
2. Locate the tensioner ramp in the base section (Figure 2-5). 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.
3. Locate the length of toothed belt that was enclosed with the extension
section. Table 2-1 lists the required length of belt for your system. Make
sure you have the right length; if you do, cut the belt anywhere between
two teeth.
4. With the toothed side of the belt toward you position the right end of the
belt about halfway along the elevator.
