spool.
5. When the encoder is in place, then support the spool while installing the four mounting bolts and
washers that you removed earlier to finger tight, but not torqued.
6. Slide the belt onto the front gear. Ensure that it rides on the back gear centered.
The front gear may be offset up to 50% width of the belt and still maintain proper operation.
There is very little force on it and it will vary from spool to spool due to machine tolerances.
7. Tighten the four bolts to 35 in-lbs (4N.m).
8. At the bottom of the encoder assembly reposition and install the Spool cable ensuring the grip
ring clips into place.
9. Verify proper operation of the spool and belt before installing the right and top covers using hard-
ware that was removed earlier.
10. Tighten all M6 hardware to 35 in-lbs (4N.m).
