Maintenance

Changing the Motor Brushes
DISCONNECT THE MACHINE FROM THE
MAINS SUPPLY BEFORE CONTINUING!
Check the carbon brushes every three months. Replace if worn.
Take careful note of the orientation of the
brushes when you remove them, remember
that they have bedded themselves to the
profile of the commutator in that position.
If you fit them reversed they may not be in
exactly the same position, which can cause
excessive sparking and heat until they have
re-bedded themselves.
