Remove upper shell (see Upper Shell Removal, page 10). 2. Remove fan (see Fan, page 10). 3. Remove fuel and air line hoses from nozzle assembly (see Figure 23, page 12 or Figure 24). 4. Turn nozzle assembly 1/4 turn to left and pull toward motor to remove (see Figure 25). 5. Place plastic hex-body into vise and lightly tighten. 6. Carefullyremovenozzlefromthenozzleadapter using 5/8" socket wrench (see Figure 26). 7. Blow compressed air through face of nozzle. This will free any dirt in nozzle area. 8. Inspect nozzle sleeve for damage. 9. Replace nozzle into nozzle adapter until nozzle seats. Tighten 1/3 turn more using 5/8" socket wrench 4.5 to 5.1 N-m (40 to 45 in-lbs). See Figure 26. 10. Attach nozzle assembly to burner strap (see Figure 25). 11. Attach fuel and airline hoses to nozzle assembly. See Fuel and Air Line Replacement and Proper Routing, page 14. 12. Replace fan (see Fan, page 10). 13. Replace fan guard and upper shell (see Upper Shell Removal, page 10).

Remove upper shell (see Upper Shell Removal, page 10). 2. Remove side cover screws using 5/16" nut driver (see Figure 19 or 20, page 11). 3. Remove side cover. 4. Inspect fuel and air line hoses for cracks and/or holes. If fuel line hose is damaged, disconnect from nozzle adapter (see Figure 23 or 24) and from fuel filter (see Fuel Filter, page 11). If air line hose is damaged, disconnect from nozzle adapter (see Figure 23, page 12 or Figure 24, page 13) and from barb fitting on pump end cover (see Figure 27). 5. Install new air and/or fuel line. Attach one end of air line hose to barb fitting on pump end cover (see Figure 27) and the other end to nozzle adapter (see Figure 23, page 12 or Figure 24, page 13). Attach one end of fuel line hose to fuel filter (see Fuel Filter, page 11) and the other end to nozzle adapter (see Figure 23, page 12 or Figure 24, page 13). Note: Route hoses as shown in Figure 23, page 12 or Figure 24, page 13, according to model. Hoses are not to touch photocell bracket. 6. Replace side cover. 7. Replace upper shell and fan guard (see Upper Shell Removal, page 10). Pump End Cover Barb Fitting Air Hose Barb Fitting 40/55/70 Models 115/165 Models Figure 27 - Air Hose to Barb Fitting 1. Remove upper shell (see Upper Shell Removal, page 10). 2. Remove filter end cover screws using 5/16" nut driver (see Figure 28 or 29). 3. Remove filter end cover and air filters. 4. Remove pump plate screws using 5/16" nut-driver. 5. Remove pump plate. 6. Remove rotor, insert, and blades (see Figure 28 or 29). 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 .076/.101 mm (.003"/.004") if needed (see Figure 30, page 15). Note: Rotate rotor one full turn to ensure the gap is .076/.101 mm (.003"/.004") at tightest position. Adjust if needed. 10. Install blades, pump plate, air filters, and filter end cover. 11. Replace fan guard and upper shell (see Upper Shell Removal, page 10). 12. Adjust pump pressure (see Pump Pressure Adjustment, page 11).
