[3]-1. Rotor, Ball bearing 629LLB, 607LLB, Spiral bevel gear 10 (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. 3R
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.
