- Remove the Sweep Hose by twisting the nut to release it from the hose or by removing the Sweep Hose attachment clamp.
- Set the cleaner on its side on the double wheels.
- Loosen the three (3) screws on the underside of the cleaner (Figure 4). Tilt the cleaner over and allow screws to drop out.
- Remove the bottom housing.

NOTE: The left screw (1) is deeply recessed. To retrieve the screw after loosening, turn the cleaner over and it will fall out.
- Set cleaner on its single-side wheel. Insert a small flathead screwdriver under the hubcap notch to pry hubcaps from both double-sided wheels. (Figure 10.)
- Remove screws from the center of each wheel (Figure 11) and slide the wheel off to remove them (Figure 12). NOTE: Wheel screws are smaller in diameter than body screws. Set these screws apart from other screws to prevent mixing.
