On the other hand, a standby generator might operate as little as 26 hours a year based on only 30 minutes of weekly exercise and no outages or as much as several hundred hours a year, depending upon the number and duration of power outages.
In either case, a standby generator set could conceivably last 20 to 30 years. The maintenance cycle can— and should —be adapted to meet specific application needs. The more hours per year a unit operates, the more frequently it will require service.
Generator Maintenance Checklists
Environment also plays a role: The more severe the environment dusty, extremely hot or cold, highly humid, etc. Most OEM-recommended maintenance schedules for generators— whether a unit is powered by diesel or gaseous fuels —are roughly the same. The typical maintenance cycle includes a general inspection followed by scheduled inspection and service of the following critical systems:.
At a minimum, a good visual inspection should be done on a monthly basis, as well as after any extended generator run times.
Here are some basic tips:. In addition to monthly inspections; check the coolant thermal-protection level every six months. Use the appropriate tester for the type of coolant being used. At the same time, inspect the accessory drive belts for correct tension and condition. Annual maintenance of your standby generator begins with changing the engine oil and filter. If you want to extend oil-change intervals, consider an oil-analysis program.
This will give you recommendations based on the actual condition of the lubricating oil.
Replace the air filter and fuel filters, as well. If it is a diesel unit that does not use a lot of the fuel in its storage tank, consider having the fuel in the tank filtered and checked for additive content. The above items are by no means a complete list. Other PM aspects worth considering include the conducting of weekly exercise periods under load to test the entire system for proper operation and make the generator work at operating temperature.
OEMs provide detailed standby generator maintenance guidelines that should be followed to provide the longest most reliable service life possible for their respective equipment. General guidelines for specific applications also can be found in several recognized standards.
Standby Generator Maintenance – Be Prepared for Power Outages
It is an excellent resource on general-maintenance requirements and detailed information on some specific maintenance items. This standard also contains a suggested maintenance schedule which, if followed, will meet minimum maintenance requirements for Level 1 and Level 2 emergency standby power systems.
Remember: Establishing and following a thorough maintenance and service plan will provide you with a reliable power supply for many years. Be sure to take note of the frequency recommendations for these maintenance activities. This is a unique website which will require a more modern browser to work! Please upgrade today! Here are some basic tips: Maintain general cleanliness of the generator and its surroundings. In an enclosed unit, make sure there are no rodents trying to take up residence.
If the generator has been running, wait for 10 minutes after it shuts down to check the oil level this allows all of the oil in the engine to drain back into the sump.
Maintain the oil level as close to the full mark as possible without overfilling.
Add fuel and drain water from the separators as necessary. For gaseous units, inspect the fuel-supply piping for leaks or obvious damage. Confirm that there are no loose clamps or wire connections, and no corrosion or damage to terminals or wiring. Inspect batteries for cleanliness and signs of corrosion.
Check the operation of the battery charger.
What is generator maintenance?
Semi-annual inspections In addition to monthly inspections; check the coolant thermal-protection level every six months. Dirt, heat and moisture are their biggest enemies. Dirt can block the heat transfer necessary to keep the windings cool. Heat can damage the insulation on the windings.

Moisture can cause windings to short to each other or to ground. Any of these situations will reduce the power that a winding can produce. Transfer switches can be a little more challenging to inspect and maintain. To do a thorough annual inspection requires turning off all power to the switch.
This may involve coordinating a planned outage for a specific time period on a weekend or during the night.
Why Perform Generator Maintenance Inspections?
Other standby generator preventive maintenance aspects The above items are by no means a complete list. Weekly Maintenance Run the generator typically no-load, automatic transfer switch exercise cycle.
Verify that the unit ran and has no alarms or warnings. Ensure adequate fuel levels. Check that the circuit breaker is closed.
