8. How to replace carbon brushes
1. It is recommended to replace the pair of carbon
brushes to maintain performance when worn out to
about half the length.
2. Carbon brush caps have a slot.
Unscrew them with a flat tip driver
to open them. Be careful not to
allow the carbon brush inside to
jump out as it is kept there under
spring pressure.
3. With the mini-type screwdriver,
one of the carbon brush covers
is located under the switch lever,
therefore, the switch lever must be
removed before reaching it. Turn
the hexagonal head of the axis
supporting the switch lever, then
they can be removed.
4. Replace the worn carbon brushes with new pair. Note
that the end surface of the carbon piece is not exactly
flat but of slightly concave face, so see to that the
carbon piece is placed in the correct direction when
inserted into the holder to have its curved face make
smooth meeting with the rotation of the deep inner
commutator. Screw the cap tightly.
