(3) Place the J1 belt around the pulley of the Joint #1
motor unit to secure the unit loosely.
Make sure that the gear grooves of the belt are fit
into those of the pulleys completely.
Put the motor cable facing toward the other side of
Joint #1.
When securing the motor unit, make sure the unit
can be moved by hand, and it will not tilt when
pulled. If the unit is secured too loose or too
tight, the belt will not have the proper tension.
