4 BRIGGSandSTRATTON.COM Important Safety Instructions WARNING The engine exhaust from this product contains chemicals known to the State of California to cause cancer, birth defects, or other reproductive harm.
5 WARNING Generator voltage could cause electrical shock or burn resulting in death or serious injury. Use approved transfer equipment to prevent backfeed bt isolating generator from electric utility workers. • When using generator for backup power, notify utility company.
6 BRIGGSandSTRATTON.COM CAUTION Excessively high operating speeds could result in minor injury and/or equipment damage. Excessively low speeds impose a heavy load on generator. • DO NOT tamper with governed speed. Generator supplies correct rated frequency and voltage when running at governed speed.
7 WARNING Exhaust heat/gases could ignite combustibles or structures resulting in death, serious injury and/or property damage. • Keep at least 5 feet (152 cm) of clearance on all sides of generator including overhead.
8 BRIGGSandSTRATTON.COM Fuel Tank Cap Vent Lever The fuel tank cap is provided with a vent lever ( A , Figure 2) to seal the fuel tank. The vent lever must be in the “ON” position for the engine to run. When the engine is not in use, leave the vent lever in the “OFF” position to reduce the possibility of fuel leakage.
9 Generator Components A - Fuel Tank Cap Vent Lever — Turn the vent lever to the “ON” position when operating the generator. Turn to the “OFF” position when not in use. B - Fuel Tank — Capacity of 1.0 U.S. gallon (3.7L). C - Choke Lever — Used when starting cold engine.
10 BRIGGSandSTRATTON.COM Maintenance Maintenance Schedule Follow the hourly or calendar interval, whichever occurs first. More frequent service is required when operating in adverse conditions noted below.
11 WARNING Unintentional sparking could cause fire or electric shock resulting in death or serious injury. When Adjusting Or Making Repairs To The Generator • Disconnect the spark plug wire from the spark plug and place the wire where is cannot contact spark plug.
12 BRIGGSandSTRATTON.COM Changing Engine Oil If the generator is used under extremely dirty or dusty conditions, or in extremely hot weather, change the oil more often. CAUTION Avoid prolonged or repeated skin contact with used motor oil. • Used motor oil has been shown to cause skin cancer in certain laboratory animals.
13 Service Spark Plug 1. Loosen the four handle screws and remove the handle (Figure 8). Figure 8 2. Remove the top maintenance cover. 3. Clean area around spark plug and remove spark plug boot (Figure 9). Figure 9 4. Remove spark plug and inspect for pitting, corosion, cracks, or other signs of damage.
14 BRIGGSandSTRATTON.COM Inspect Muffler and Spark Arrester Inspect the muffler for cracks, corrosion, or other damage. Remove the spark arrester, if equipped, and inspect for damage or carbon blockage. WARNING Exhaust heat/gases could ignite combustibles or structures resulting in death, serious injury and/or property damage.
15 Rewind Starter Replacement Disassemble Rewind Starter 1. Remove control panel, inverter, and fuel tank as described in the Troubleshooting section. 2. Locate the rewind starter handle ( A , Figure 13) and remove the screw that is located under the handle.
16 BRIGGSandSTRATTON.COM Figure 15 Inspect Rewind Starter Parts 1. Inspect the pulley for wear, cracks, rough edges, or burrs in the rope groove and look for wear in the center hole. If wear or damage is found, replace the pulley and spring assembly. 2.
17 Troubleshooting Fuel System Fuel Pump The fuel pump ( A , Figure 16) is located on inside of cover. It is operated by vacuum pulses from the engine.
18 BRIGGSandSTRATTON.COM Fuel Valve The fuel valve is mounted behind the side maintenance cover. Check the valve for proper operation as follows: 1. Using small, flat-head screwdriver, pry off cover to the fuel valve knob (Figure 19). Figure 19 2. Remove screw under the cover to remove the knob ( B , Figure 20).
19 2. Remove control panel from enclosure and, without disconnecting wiring, set control panel aside ( D , Figure 23). 3. Remove inverter from enclosure ( E ) and, without disconnecting wiring, set inverter assembly aside. Figure 23 E D 4. Close vent on fuel cap.
20 BRIGGSandSTRATTON.COM 4. Remove breather filter ( B , Figure 29) to expose the air cleaner assembly screw. Loosen and remove screws ( C ) to remove air cleaner assembly.
21 5. Remove air cleaner assembly and set aside (Figure 30). Figure 30 7. Remove the hose that is connected to carburetor assembly (Figure 32). 8. While leaving the stepper motor attached, carefully slide carburetor assembly off engine. 9. Remove bowl nut (Figure 33) and the fuel bowl.
22 BRIGGSandSTRATTON.COM 11. Ensure the inlet needle and spring ( A ) are assembled correctly, with the spring located below the float bosses (Figure 35). 12. Using a carburetor nozzle screwdriver, remove the main jet and emulsion tube (Figure 36). Clean as needed.
23 Stepper Motor The stepper motor (electric throttle actuator) responds to the inverter module to continuously match engine speed to the power needs of the generator. The stepper motor (Figure 37) is attached to the top of the carburetor assembly. Figure 37 Before removing the motor assembly, first check the resistance of the motor lead wires.
24 BRIGGSandSTRATTON.COM 4. Actuate the throttle lever to check for proper movement (Figure 42). The lever should move freely in both directions. 5. If the linkages stick, spray lubricant on the lever and manually move the lever. This should free the linkages.
25 Engine Will Not Start The Engine Cranks But Has No Spark If the engine cranks but has no spark, it could be the micro switch ( A , Figure 43). Test the continuity of the microswitch as follows: 1. Remove the control panel. 2. Disconnect the 10-pin connector (Figure 44) that is connected to the ignition module (module with three LED lights).
26 BRIGGSandSTRATTON.COM Low Oil Switch The low oil indicator system is designed to prevent engine damage caused from insufficient engine oil. If the engine oil level drops below a preset level, the yellow LED low oil indicator light (Figure 47) illuminates and an oil switch will stop the engine.
27 Ignition Spark Circuit When the engine is running the 27V coil produces a voltage that is present at the ignition module. When the magnet on the flywheel (rotor) passes by the trigger coil, this trigger voltage is sensed by the ignition module.
28 BRIGGSandSTRATTON.COM Test Ignition Coil 1. Locate the connector for the ignition coil ( A , Figure 56) and disconnect.. 2. Attach meter test leads to primary side of the ignition coil and measure the resistance ( B , Figure 57). • If resistance is 0.
29 Figure 58 3. Attach one test lead to either terminal of ignition coil connector and the other lead to the spark plug cap (Figure 58) to measure the secondary resistance.
30 BRIGGSandSTRATTON.COM 3. Measure for 120 VAC ouput ( C , Figure 62). 4. Disconnect the main winding connector and measure resistance across the windings ( D , Figure 63). 5. Then measure resistance across sub-windings ( E , Figure 64). • If resistance is 1.
31 2. Disassemble panel cover to locate and check the wire connections ( A , Figure 66). 3. Locate battery winding connector ( B , Figure 67) and mesure resistance across the terminals ( C ). Figure 66 A A • If resistance is 0.3 - 0.7 Ω the winding is good.
