[3] DISASSEMBLY/ASSEMBLY
[3] -2. Gear assembly, Rotor, Stator assembly,
Speed change lever assembly (cont.)
Caution for Handling of Rotor
When handling or storing multiple Rotors, be sure to keep a proper
distance between Rotors as shown in Fig. 13
because Rotor is a strong magnet, failure to follow this instruction
could result in:
• Finger injury caused by pinching between Rotors pulling each other
• Magnetic loss of Rotors or damage on the magnet portion of Rotor.
(Fig. 14)
ASSEMBLING
(1) Put Rotor into Stator complete as drawn in Fig. 15.

1. Holding Stator complete on a workbench, insert Rotor
slowly in Stator complete until Rotor's drive end
reaches the workbench.

(2) Make sure that Rotor's gear engages with the super gears of Gear assembly
to rotate them smoothly, and push Rotor section (Rotor and Stator) fully in
Gear assembly, (Fig. 16)
(3) Assemble Speed change lever assembly as drawn in Fig. 17.
