Portable Generators:

Carburetor Maintenance:
  • Run unit every 30 days with a load to keep fuel from gumming up the carburetor.
  • When you are finished using the generator shut it down by turning off the fuel line. This will allow the generator to continue running until the fuel has been basically drained from the carburetor which will help prevent carburetor problems.
  • Purchase a container of stable and pour it into the fuel tank. This will help to keep the carburetor clean.
Battery Maintenance:
  • If the battery is not a 0 maintenance battery check it's specific gravity monthly and add water if necessary. If the specific gravity reading on the battery is low the battery should be replaced as this means the acid level of the battery is low.
  • If the battery is over three years old you should consider replacing the battery as most batteries will not last much longer than 3 years.
  • Run the generator monthly for an hour with a load. This will allow the generators built in charging system to charge the battery and help keep the engine running well.
Oil Maintenance:
  • Generally generators without an oil filter should have their oil changed every 50 hours or once a year. This should be verified with the manual provided by the manufacturer.
  • Generally generators with an oil filter should have their oil and oil filter replaced every 250 hours or once a year. This should be verified with the manual provided by the manufacturer.
  • Oil level should be checked prior to running the engine every time. This will help to insure the unit has proper oil level which will prevent damage to the engine. If the oil level appears low top it off with oil having the viscosity recommended by the manufacturer of the engine. This information should be available in the generator's manual.
  • Check for leaks. After you have verified you see no signs of oil on the engine run the unit and verify you don't see any oil leaking from the engine.
General Maintenance:
  • Periodically check any hoses, and wires on the generator for signs of wear, cracking or pealing, or dry rotting. If you do see any of these signs the hose or wire should be replaced as soon as possible.
  • If the unit has a transfer switch attached to the house it is recommended that you perform a transfer test monthly to verify proper operation of the generator under load and the transfer switch.
Running The Generator:
  • Before running the unit every time verify the proper level of oil and check the oil to make sure it is relatively clean and free from dirt. Check your hoses and wires for any kind of wear. Verify the exhaust is clear of any kind of debris.
  • Remember generators use engines which put out carbon monoxide. To prevent carbon monoxide from building up in your home you will want to make sure the generator is a safe distance from any doors or windows on your home and that the exhaust pipe is pointed away from your home.
