Check Carbon Brushes for wear periodically.

do not, chances are that you will have a rectification
problem which may cause machine failure. (Fig.28)

new one.
(3) Put the cover on and securely tighten the tap
screws. When tightening the tap screws, see
that the tap screws are screwed in along the
existing screw threads – without cutting new
threads.
