Check the oil and fuel levels in your generator if the unit will not start. Use a 15W-40 oil. Screw the dipstick all the way down to obtain the correct oil level reading. Replace fuel that has been sitting for longer than 30 days. If it has been in the tank for longer than this, it could be contaminated and cause problems with starting the generator.
Run, or exercise, the generator at intervals to keep the engine and seals lubricated. This also prevents carbon from building up and heats the generator windings to expel excess moisture. Exercising can prevent corrosion build-up on the slip rings.
Verify there is sufficient battery fluid in the battery if the generator fails to crank. Clean and tighten all the battery and cable connections. Inspect the fuse on the control panel. If it is blown, replace it with another fuse of the same amperage. Disconnect the work-load before starting if the generator cranks too slowly.
Remove the spark plug with the wrench if the generator cranks but will not start. Use a wire brush to clean carbon deposits from the plug. Replace the spark plug if it is damaged in any way.
Switch the generator to the "winter" position during cold, humid conditions of 55 degrees Fahrenheit or less. This will prevent carburetor icing and rough operation or stalling. The generator is equipped with a summer/winter lever. Switching to "winter" will pre-heat the intake air, preventing ice from forming in the carburetor.
Replace the air filter if the unit is exhausting black smoke. Remove the access cover and air filter cover. Lift out the air filter. Tap the filter against your hand to dislodge debris and dust. Use a vacuum if the filter is excessively clogged. Once the access cover is removed, the air filter is on the left side.
Inspect the generator for any blocked vents and air flow if the unit starts and runs, then stops when the start switch is released.
