all further disassembly or reassembly be completed by a factory professional. Units should be
sent directly to the factory for repairs or service.
CAUTION
TSE units are spring loaded. Never remove
Snap Ring on Hub-Disc when removing Rear

wear safety goggles when working with spring
or tension loaded fasteners or devices.
