Drive Motor Carbon Brush Replacement

Do not use a pressure washer to clean around the
motors. Use tap pressure only.
FOR SAFETY: Before leaving or servicing machine,
stop on a level surface, turn off machine and remove
motor carbon brushes.
1. Open the console cover.
2. Tilt the recovery tank back until it stops on the
lanyard.
3. Grasp the lower end of the flexible steering shaft
and pull it straight up until it is disengaged with the
hex steering shaft. Place the loose end into one of
the fill ports.
4. Remove the cover and gasket at the steering shaft
area.
5. Grasp the drive wheel by reaching under the front
bumper and turn it to near the left steering stop.
6. The drive motor carbon brushes are located under
screw caps. The caps are accessible by gently
moving the harness aside.
7. Rotate the drive wheel to near the right hand stop
to access the right side carbon brush.
8. Replace the gasket and cover, set the drive wheel
straight ahead, set the steering wheel straight
ahead, and gently align the steering shaft coupling
and slide onto the lower shaft.
9. Slowly close the cover and make sure the shaft
slides without binding.

side of the loop when the opposite side is tight.
To adjust chain tension:
1. Remove bumper.
2. Loosen five (5) 10mm screws that hold the drive
gear motor and slide the gear motor up until the
chain tension is correct. Retighten the five (5)
mounting blots.
