Since the first engines began to power the world, they have required maintenance to keep them running. Lack of maintenance is a sure path to breakdown and service interruption. To put it in perspective, normally we are used to tuning up our motor vehicles with frequent checkups, fluids and filters. Parts wear out; fluids break down or get used up. Routinely parts will slip a little out of place or will wear on specific locations and soon enough these small problems turn into larger ones ending up in the engine being out of tune. A standby generator is really quite comparable. Like an automobile, they are powered by internal combustion engines. Having an on schedule maintenance routine will keep your standby generator prepared for any type of power outage. Before performing maintenance, follow the manufacturer’s directions for disabling the generator and ensure the unit will not start while operating on it
The engine is lubricated by oil. If there is an unsatisfactory amount of lubrication for the engine, most generators will automatically disable to prevent any injury. Throughout operation, oil level or oil pressure sensors will alert the generator’s controller if the oil pressure or level drops beneath suitable levels. At this time, the controller will deactivate the generator. Check the oil level month-to-month and increase oil as needed. During prolonged operation, check the oil often. For some generators the oil filter will need to be changed as often as every 100 hours of operation for certain types of generators. Be sure that you are using the correct type of oil viscosity for the temperature range you generator experiences.
Air-cooled generators have cooling vents that guide air over the engine while it is working. Keeping these vents clear of any debris or obstruction is most critical to allow the engine to breathe. Examine the cooling vents and air intakes and remove any leaves, grass, or other debris that blocks the vents. Also, all lids sides and doors are properly fastened and locked tight. Inspect the cooling system on liquid-cooled generators for proper coolant levels and top off the coolant as needed. Search for cracked or leaking hoses and loose clamps. Replace any parts that are damaged or have apparent deterioration. Change the coolant as necessary according to the maintenance schedule found in the owner’s manual. On a liquid-cooled generator be sure to keep an eye on the fan belt for wear and tear, cracks, or any other type of signs leading to failure. Always be sure to replace a belt before it malfunctions and breaks as this can lead to more damage to the unit.
