Generators are maintained to keep track of their electrical and mechanical components to ensure quality service. Before the operation and maintenance of the generator sets, please read and fully understand the generator’s features, warning and maintenance steps in the manual and other documents that come with the unit in order to familiarize yourself with operation and maintenance processes. If the generator operates for more hours it will frequently require service.  Maintenance should only be carried out when the unit is not actively working.


 Service schedule

Observe user’s manual maintenance schedule for your generator and keep your record book updated with the dates of service and any issues found and fixed. Check for corroded elements, stuck buttons, loose wires, spark plugs, fuel pumps, turbocharger, injectors, bolts etc.

Lubrication service

As the generator has a lot of movable parts and gears, it is advisable to lubricate each of its moving parts regularly for proper functioning. Make use of good, quality lubricants.

Cooling system

Use the proper generator coolant to avoid overheating when running the generator for longer hours. And always check the coolant level during the shutdown period at the specified interval.

Battery inspection

Always ensure the battery is fully charged and well-maintained to avoid battery decay. It should always be cleaned and the specific gravity and electrolyte levels checked. Also, check the battery voltage and the distilled water in the battery. Top up if needed. Replace your battery every 2-3years.

Fuel system

Drain the fuel filters at the designated intervals because of the water vapour that collects and liquefy in the fuel tank. Fuel lines and filters can get clogged within weeks of operation. When this happens, they should be cleaned using biocides.

Power up your generator

Make a point of running your generator for about half an hour every three months to charge the battery. This will ensure that it will start up smoothly when you need it to.




Always clean the generator post-use by removing grease, fuel etc.  If there are any signs of corrosion, treat with inhibitor products. Keep the generator in a dry space and cover it up to keep away dust.

Fill up your tank

Ensure the tank is filled with gas to avoid damaging the generator. If you have fuel in there,  use  a stabilizer so that your ethanol does not undergo separation and cause damage.

Exhaust system inspection

 Inspect the exhaust system entirely including the exhaust pipe to ensure there are no leaks along the exhaust line, weld, gaskets and joints and in case there are, repairs should be made immediately.


Always monitor oil pressure, coolant temperatures and fluid levels regularly since in most cases engine issues give an early caution. Pay attention to changes in sound and engine performance for they will indicate when the generator needs service. Be on alert for vibration, excessive exhaust smoke or loss of power.

If you are having problems with your generator, contact your favourite OKC electrician, Colburn Electric.
