6. Lightly grease axle and then reassemble wheel. The
brushes should rotate only during forward rotation of
the wheel. If the brushes are driven (rotated) by both
forward and reverse rotation of the wheel, the drive
pin is jamming in the ratchet gear. Disassemble to
clean and lubricate drive pin and ratchet gear.
