10REPLACEMENT OF CARBON BRUSHES ON ELECTRICMOTORS AND FUSES1) Drive motor (front wheel) (Figure C).2) Carbon brush protection cap ( N. 2) (Figure C, Pos. 1).3) Side brush motor (Figure D).4) Carbon brush protection (N. 2) (Figure D, Pos. 4).5) Fan/main brush motor (Figure B).6) Carbon brush protection ring (N. 1) (Figure B, Pos. 6).7) Carbon brushes (Figure B-C-D, Pos. 7).8) 3A fuse (headlights) Figure A, Pos. 8).9) 50A fuse (general) (Figure A, Pos. 9).To replace carbon brushes:a) Remove protections.b) Remove carbon brushes (if worn out) and replace with new ones.c) Reposition the protections.ImportantThe carbon brushes of electric motors should be periodically checked (at least every 200 hours if used on hardfloors and 125 hours if used on carpet) and replaced if worn out. Both the performance and the life of the motorsgreatly depend on the state of these components. A worn out brush is 3/8 in. long or less.https://harrissupplyind.com - To Order Parts Call 608-268-8080
