.076/.101 mm (.003"/.004") if needed
(see Figure 17).
Note: Rotate rotor one full turn to insure the
gap is .076/.101 mm (.003"/.004") at tight-
est position. Adjust if needed.
10. Install blades, pump plate, air filters,
and filter end cover.
11. Replace fan guard and upper shell.
12. Adjust pump pressure (see page 7).
Note: If rotor is still binding, proceed as
follows.
13. Perform steps 1 through 6 above.
14. Place fine grade sandpaper (600 grit)
on flat surface. Sand rotor lightly in
