10.Install blades, pump plate, air filters, and filter end cover.

11.Replace fan guard and upper shell (see Upper Shell Removal, page 9).

12.Adjust pump pressure (see Pump Pressure Adjustment, page 10).

Note: If rotor is still binding, proceed as follows.

13.Perform steps 1 thru 6.

14.Place fine grade sandpaper (600 grit) on flat surface. Sand rotor lightly in “figure 8” motion four times (see Figure 28).
