Clean circuit board terminals.
Securely reconnect leads.
Tighten terminal screws. Replace brushes if leads are damaged.
Replace brushes.
For loose motor brush lead connections and terminals.
Brushes must be 1/2 in. [13mm] minimum. NOTE: Brushes do not wear at the same rate on both sides of motor. Check both brushes.
Broken or misaligned motor brush springs. Rolled portion of spring must rest squarely on top of brush.
Motor brushes may be binding in brush holders.
Motor armature commutator for burn spots, gouges or extreme roughness.
Replace spring if broken. Realign spring with brush.
Clean brush holders. Remove carbon with small cleaning brush. Align brush leads with slot in brush holder to assure free vertical brush movement.
