ASSEMBLING
Because Yoke unit is a strong magnet, when assembling Armature to
Yoke unit, be sure to hold the commutator portion as illustrated below
on
left
.
Do not hold the Armature core as illustrated to right or your
fingers will be pinched between Yoke unit and the fan of Armature
that is pulled strongly by the magnet force.
Yoke unit is directional when assembled
to Armature. Be sure to assemble so that
the notch in Yoke unit is positioned on
the drive-end of Armature.
If assembled wrong, the Motor section
cannot be assembled to Housing (L).
