NOTE: 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.
2. Carefully remove the motor brush, see fig 39. Check the brush
for signs of wear. If it's O.K. re-fit. If the brush has worn down to
a theard of its length replace with a new one.
3. Turn the scroll saw on its side allowing access to the other
brush access port, see fig 40-41.
