Remove upper shell (see page 10). 2. Remove fan (see page 19). 3. Remove fuel and air line hoses from burner head. 4. Remove spark plug wire from spark plug. 5. Remove spark plug from burner head using 13/16" open-end wrench. 6. Remove three screws using 5/16" nut-driver and remove burner head from combustion chamber. 7. Place burner head into vise and lightly tighten. 8. Carefully remove nozzle from burner head using 5/8" socket wrench (see Figure 28). 9. Blow compressed air thru face of nozzle. This will free any dirt in nozzle area. 10. Inspect nozzle seal for damage. 11. Replace nozzle into burner head and tighten firmly (80-110 inch-pounds/9.112.4 n-m). 12.

Remove upper shell (see page 10). 2. Remove filter end cover screws using 5/16" nutdriver. 3. Remove filter end cover and air filters. 4. Remove pump plate screws using 5/16" nutdriver. 5. Remove pump plate. 6. Remove rotor, insert, and blades. 7. Check for debris in pump. If debris is found, blow out with compressed air. 8. Install insert and rotor. 9. Check gap on rotor. Adjust to .003"/.004" (.076/.101 mm) if needed (see Figure 33). Note: Rotate rotor one full turn to insure the gap is .003"/.004" (.076/.101 mm) at tightest 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 14). Note: If rotor is still binding, proceed as follows. 13. Perform steps 1 thru 6 above. 14. Place fine grade sandpaper (600 grit) on flat surface. Sand rotor lightly in “figure 8” motion four times (see Figure 34). 15. Reinstall insert and rotor. 16. Perform steps 10 thru 12 above.
