CAUTION

• Do not disassemble the rear hub assembly.
• The magnetic encoder collects any metallic particle easily, because it is magnetized. Make sure 

that the magnetic encoder should not collect any metallic particle. Check that there is not any 
trouble prior to reassembling it.

• When the rear hub assembly is removed and installed, make sure that the magnetic encoder does 

not contact with surrounding parts to avoid damage.
