[12] Assembling armature
Do not assemble the used self lock. The self lock has to be always replaced with the fresh one.
Note:
Pay attention to the assembling direction of Self lock and Wave washer 6. (Fig. 39)
Magnet sleeve is installed to the armature shaft on commutator side for sensing the variation of rotating speed.
If it would be damaged, the electronic speed control does not work any more.
