Caution for Handling of Rotor
Fig. 10A Fig. 10B
* Magnetic loss of Rotors
* Damage on the magnet portion of Rotors
When handling or storing multiple Rotors, be sure to keep a proper distance between Rotors as shown in Fig. 10A
because Rotor has 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 Rotors. (Fig. 10B)

3 Before pushing Rotor section (Rotor and Stator) fully
in Gear assembly, make sure that Rotor’s gear engages
with the super gears of Gear assembly to rotate them smoothly.
(1) Assemble Gear assembly and Rotor section in the reverse order of disassembly. (Refer to Figs. 9 and 8)
Note: Be careful not to pinch your fingers between Stator and Rotor’s fan when assembling Rotor. (Fig. 11)
1. While holding Stator on workbench, insert Rotor into Stator
slowly until the drive end of Rotor reaches the workbench.
2. When the drive end of Rotor reaches
the workbench, lift up Stator slowly.
