NOTICE
The motor unit is set at the initial position
when it is shipped; therefore, install it
without changing the position. If the motor
unit may not be at the initial position, push
the following shifting switch ten or more
times to move the protrusions on the motor
unit clockwise (check from the inside of the
motor unit). (Check the shifting up and down
of the shifting switch in advance as it may
have been switched by customization.) If the
motor unit is installed off the initial position,
some gears may become unavailable and the
hub or the motor unit may be damaged.
