Notes
Note: Replace 16 whenever handle halves are removed.
Note: Spring Pin (21) and Switch Paddle (24) must be removed in order to access Screw (18). See additional note below.
Notes Prior to installing a new service nameplate: Apply isopropyl alcohol to the handle cover with a clean, lint-free applicator and allow to dry. Use a thin blunt punch with the same OD or a similar tool like a finishing nail with the same OD and the pointed tip ground down to remove spring pin from the handle halves and switch paddle. As an aid, be sure to prop up that corner end of ratchet to support the tapping out of the spring pin. When reinstalling pin, align the holes and carefully press or tap the pin in place.
