Emergency Generator Maintenance Services in Port Washington, WI

Storms that cause power outages cause real headaches to residents of Wisconsin…unless they have a standby generator to provide power. That’s why savvy Wisconsinites have emergency generators regularly maintained by a certified technician who can spot problems and make repairs before the next power outage. Understanding the top benefits of a generator for your home can help you make informed decisions about your emergency power needs.

The Value of Preventative Maintenance

The average emergency power generator can run for up to 30,000 hours, translating into anywhere from 20 to 30 years of use. To get this performance, however, it is important to have an emergency generator maintenance properly. Preventative maintenance can help it run smoothly for many years so that it will always be available in emergencies.

Weekly Maintenance

A property owner needs to know a backup generator will work in emergencies. Here are some simple weekly maintenance tasks to keep backup generators in working condition:


  • Turn the generator on and make sure it runs without alarms or warning signals.
  • Check fuel levels and for leaks.
  • Ensure the circuit breaker is closed.
  • After the check, set the generator to “Auto” mode so it is ready to fire right up when you need it.

Visual Inspection

A monthly visual inspection should be performed, especially when the generator is being used. Here are the basics to check:

  • Is the generator clean? If it is enclosed, make sure it is free of rodents.
  • With the engine off, read the level of oil. It should be as close to full as possible. If the engine has been on, let it cool for about 10 minutes before checking.
  • Make sure there is enough coolant in the overflow tank.
  • Make sure the level balances of fuel and water are correct in diesel systems.
  • Check the pipe that supplies the fuel tank in gas systems for damage.
  • Check for unstable wires and clamps.
  • Make sure no terminals have corroded. 
  • Make sure the batteries are clean and the charger is working.
  • Check for loose clamps or connections between wires.
  • Look for terminal corrosion and other damage to wiring.
  • Inspect batteries for cleanliness and signs of corrosion. Make sure the charger for the battery is working.

Regular Preventative Maintenance

Maintenance schedules are normally made according to the backup generator’s type and use. Diesel generators need more maintenance than gas-fueled generators. And the more use the system gets, the more frequently it should be checked. Climate also plays a role. Generators in severe climates need more maintenance.


No matter how often it is performed, power generator maintenance includes inspection of the following:


  • The fuel system.
  • The coolant system, including water pumps.
  • The lubrication system.
  • Air system, which includes combustion air, cooling air, and air filters.
  • The ignition system, which includes batteries, the battery charger, and spark plugs.
  • The alternator.
  • The transfer switch.
