Safety Pre-Start Checks Inspect Engine and Generator looking for damaged, loose, and missing parts before set up and starting. If any problems are found, do not use equipment until fixed properly.
Starting the Engine Safety Before Starting the Engine a. Inspect the Generator and Engine. b. Disconnect all electrical loads from the Generator. c. Fill the Engine with the proper amount and type of both unleaded gasoline and oil. Manual Start 1. Turn the Engine Switch on. Setup 1 2 2. Move the Choke to the START position. 3. Turn the Fuel Valve to the ON position. 3 ON START Operation RUN OFF 4.
5 Safety 5. Allow the Engine to run for several seconds. Then, move the Choke Lever very slowly to its RUN position. Move Slowly RUN START Note: Moving the Choke Lever too fast could stall the Engine. Setup IMPORTANT: Allow the Engine to run at no load for five minutes with no load after each start‑up so that the Engine can stabilize. 6 PUT OUT AD RLO OVE LOW OIL 6. Wait for the OUTPUT light to light up. Break-in Period: a.
Connecting 120VAC Loads to the Generator Calculate Power Draw: Safety Power draw can be calculated by multiplying volts and amps. The resulting number is wattage. • Never exceed the running wattage for the Generator or any outlet amperage rating. • Refer to appliance/tool owner’s manuals to determine the wattage of electrical load devices. • Long power cords and extension cords draw additional power. Keep cord length at a minimum.
Stopping the Engine Safety To stop the Engine in an emergency, turn the Engine Switch off. EMERGENCY SHUT OFF Setup Under normal conditions, use the following procedure to shut off the Generator: 1 1. Unplug all electrical load devices from the Generator. Unplug Loads 2 Operation 2. Turn the Engine Switch off. 3. Close the Fuel Valve. Maintenance 3 ON OFF NOTICE Drain fuel at end of season or warranty is void. See Storage on page 16 for complete storage instructions.
Maintenance TO PREVENT SERIOUS INJURY FROM EQUIPMENT FAILURE: Do not use damaged equipment. If abnormal noise, vibration, or excess smoking occurs, have the problem corrected before further use. Safety WARNING TO PREVENT SERIOUS INJURY FROM ACCIDENTAL STARTING: Turn the Engine Switch of the equipment to its “OFF” position, wait for the engine to cool, and disconnect the spark plug cap before performing any inspection, maintenance, or cleaning procedures. Follow all service instructions in this manual.
Checking and Filling Fuel Safety WARNING! TO PREVENT SERIOUS INJURY FROM FIRE: Fill the fuel tank in a well-ventilated area away from ignition sources. If the engine is hot from use, shut the engine off and wait for it to cool before adding fuel. Do not smoke. 1. Clean the Fuel Cap and the area around it. 2. Unscrew and remove the Fuel Cap. 3. Remove the Strainer and remove any dirt and debris. Then replace the Strainer. Note: Do not use gasoline containing more than 10% ethanol (E10).
Air Filter Element Maintenance 2. Remove the Air Cleaner Cover and the air filter elements and check for dirt. Clean as described below. 4. Install the cleaned filter. 5. Secure the Air Cleaner Cover and replace the Access Panel before use. Safety 1. Remove the Access Panel on the side of the Generator. 3. Cleaning: • For “paper” filter elements: To prevent injury from dust and debris, wear ANSI-approved safety goggles, NIOSH‑approved dust mask/respirator, and heavy-duty work gloves.
Storage When the equipment is to remain idle for longer than 20 days, prepare the Engine for storage as follows: Safety 1. CLEANING: Wait for Engine to cool, then clean Engine with dry cloth. NOTICE: Do not clean using water. The water will gradually enter the Engine and cause rust damage. Apply a thin coat of rust preventive oil to all metal parts. 2. FUEL: To protect the fuel tank during storage, fill the tank with gasoline that has been treated with a fuel stabilizer additive.
Troubleshooting FUEL RELATED: 1. Fill fuel tank with fresh 87+ octane stabilizer-treated unleaded gasoline and open fuel valve. Do not use gasoline with more than 10% ethanol (E15, E20, E85, etc.). 2. Choke not in START position, cold engine. 2. Move Choke to START position. 3. Gasoline with more than 10% ethanol used. (E15, E20, E85, etc.) 3. Clean out ethanol-rich gasoline from fuel system. Replace components damaged by ethanol. Use fresh 87+ octane stabilizertreated unleaded gasoline only.
Problem Engine misfires Possible Causes Probable Solutions 1. Check wire connections. 2. Incorrect spark plug gap or damaged spark plug. 2. Re-gap or replace spark plug. 3. Defective spark plug cap. 3. Replace spark plug cap. 4. Old or low quality gasoline. 4. Use only fresh 87+ octane stabilizer-treated unleaded gasoline. Do not use gasoline with more than 10% ethanol (E15, E20, E85, etc.). 5. Incorrect compression. 5. Diagnose and repair compression.
