INSTALLING THE LINERS (FIGURE 3)
1. Lay the machine down on its back exposing the underside of the machine.
2. Before installing new liners, check the wheel housing and its corners for wear.
3. Install the pressure screw (4) for the top liner (3).
4. Insert the top liner (3) through the bottom and rotate it around the motor shaft into the upper part of the housing.
5. Place the side liners (1 & 2) in the housing, so the threaded studs can be pushed through the holes in the side of the housing.
6. Thread the nuts onto the studs and tighten them slightly.
7. Position the side liners (1 & 2) so the liners stick out at the bottom of the housing approximately .09” (2 mm).
8. Tighten the side liner nuts.
9. Tighten the pressure screw (4) until the edges of the top liner (3) are in contact with the upper edges of the side liners (1 & 2).
