Indicates a hazardous situation which, if not avoided, could result in death or serious injury. Indicates a hazardous situation which, if not avoided, could result in minor or moderate injury.
Set up Precautions 1. Gasoline fuel and fumes are flammable, and potentially explosive. Use proper fuel storage and handling procedures. Do not store fuel or other flammable materials nearby. Safety 2. Have multiple ABC class fire extinguishers nearby. 3. Operation of this equipment may create sparks that can start fires around dry vegetation. A spark arrestor may be required. The operator should contact local fire agencies for laws or regulations relating to fire prevention requirements. 4.
Operating Precautions 13. Avoid substantially overloading which will trip the circuit breaker. Slightly overloading the generator may not trip the circuit breaker, but will lead to premature generator failure. 14. Do not attempt to connect or disconnect load connections while standing in water, or on wet or soggy ground. 2. Never use a generator indoors, including in garages, basements, crawl spaces and sheds.
Operating Precautions (cont.) Safety 26. Use only accessories that are recommended by Harbor Freight Tools for your model. Accessories that may be suitable for one piece of equipment may become hazardous when used on another piece of equipment. 27. Do not operate in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Gasoline-powered engines may ignite the dust or fumes. 28. Stay alert, watch what you are doing and use common sense when operating this generator.
a. Unplug all devices from the generator. b. Turn the engine switch to its “OFF” position. c. Allow the engine to completely cool. d. Then, remove the spark plug cap from the spark plug. 2. Keep all safety guards in place and in proper working order. Safety guards include muffler, air cleaner, mechanical guards, and heat shields, among other guards. 3.

Operation Read the ENTIRE IMPORTANT SAFETY INFORMATION section at the beginning of this manual including all text under subheadings therein before set up or use of this product. Safety Pre-Start Checks Inspect engine and equipment looking for damaged, loose, and missing parts before set up and starting. If any problems are found, do not use equipment until fixed properly.
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. Note: Do not use gasoline that has been stored in a metal fuel container or a dirty fuel container. It can cause particles to enter the carburetor, effecting engine performance and/or causing damage.
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. 1. To start a cold engine, pull the START Knob out to the START position. To restart a warm engine, push the START Knob in to the RUN position. 1 Setup 2. Open the Fuel Valve. 2 OFF ON ON 3. Turn the Engine Switch to START. OFF START Operation 4.
Wattage Estimates 1. The total combined load through the outlet on the Generator must not exceed the rated maximum power of the unit. Wattages listed below are estimates for that type of equipment only. Check nameplate wattages on all loads before connecting to Generator. This Unit Can Power Any Running Start-up 2. Reduce the load if the AC Circuit Breaker turns off.
Maintenance WARNING Safety TO PREVENT SERIOUS INJURY FROM ACCIDENTAL STARTING: Turn the Power 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.
