Carbon Brush Notes:
− The original (new) length of each carbon brush is 1” (25.4mm) on brush and wheel drive motors.
− Replace carbon brushes when shorter than 3/8” (10mm) {1/4” (6mm) for drive motor} to obtain
the same motor efficiency as new brushes.

Important:
Motor damage resulting from failure to service the carbon brushes is not covered under
warranty. See the Limited Warranty Statement.
