1) Insert Armature into Yoke unit as described in Figs. 14 and 15.

Because Yoke unit is a strong magnet, when assembling Armature
to Yoke unit, be sure to hold the commutator portion as illustrated
to 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 not reversible when assembled
to Armature.
Be sure to assemble so that the notch in
Yoke unit is positioned on the drive-end
of Armature.

cannot be assembled to Housing L.
