When a severe storm hits, there is a risk it could knock out the power. It doesn't matter if it is wind, snow, ice, or lightning, you need to be ready. When heat, air conditioner, or appliances must be turned on, your emergency generator cannot fail. Keep your generator in working condition year-round so you are always ready. Follow our maintenance tips to maintain your emergency generator.Check and Change the Oil
Before starting your generator, check the oil level. To maintain the generator, change the oil regularly. The oil and filter should be changed after 500 hours or yearly for unused generators. Some manufacturers recommend changing the oil after the first eight hours of use. Clean the Generator
Good maintenance helps your generator last a long time. While in operation, rotators and stators collect dust, debris, and other contaminants. They do not generate energy as efficiently as possible and burn out faster. Clean the air filters weekly to eliminate debris.
Check for oil drips, leaks, and damage. Inspect the hoses and belts. Keep the exterior clean.
Check the Fuel
Do not allow fuel to sit dormant in the tank for too long. Diesel is prone to contamination and corrosion within one year. Run the generator regularly and replace the fuel every three to six months. Consider adding a fuel stabilizer or draining fuel. Change the Battery
If your generator uses a battery, ensure it is charged before storing it. If possible, plug the battery into a trickle charger to keep it ready. Test the battery regularly to ensure it is in working condition. Check the battery connection for corrosion or looseness. You can clean the cables with baking soda and water. Change your battery every 2-5 years. Unchanged or weak batteries are one of the most common causes of generator failure.Run it Regularly
If you only bought a generator for emergencies, you (hopefully) aren't using it often. To ensure it does not fail you, start your generator once a month to keep it lubricated by oil.
Replace Plugs and Filters
Air Filters need to be checked and replaced every six months. Depending on where you store the generator, you may need to replace them more often. A new spark plug ensures a proper fuel-air mixture which helps the engine run more efficiently.Proper Storage
Store your generator in a dry, cool, and ventilated location. Store it somewhere easily accessible. Ensure the generator is gas-free before storing it.Preventative Maintenance
Prolong the lifespan of your generator by following a maintenance schedule. There are different tasks to perform weekly, monthly, bi-annually, and yearly. To keep track, follow this chart from Depco Power Systems.
Conclusion
Regular maintenance extends the generator's lifespan. Check the oil and change it regularly. Keep the generator clean to avoid dirt buildup. Do not allow the fuel to sit too long, this will cause it to become contaminated. If applicable, change the battery and keep it charged.
Start your generator once a month, don't let it sit idle. Replace filters and spark plugs to run the engine more efficiently. Store the generator properly and keep up with your maintenance schedule.
