The forward and reverse motion switches are located in the side of the case with the switch buttons PN 3127 coming up through the side frame of the case.

Access to the switch box is not from inside the case but rather from the outside of the case. The side panel drops down after removing the bottom metal trim (pull slightly outward on the bottom of the panel). When the panel drops the back of the switch box is exposed. The cover is held in place by two small nuts on screws from the front of the switch box. The installation of the switches requires solder connections with tight tolerances. Because the connections are very close proximity to the switch box enclosure be certain to replace the paper insulator when replacing the switch cover. This is not a "plug and play" type installation and requires a higher level of skill.
