When the electricity goes out for an extended period, powering up your generator is a lifesaver. You can keep your food from spoiling, power any medical equipment, charge your phone, and run your TV to keep you informed about any updates. You never want to be without it when the lights go out, so you must maintain it properly. But how?
Check the Spark Plugs
First and foremost, if you have a generator that runs on gas or propane (one with a spark-ignition engine), it has one or more spark plugs that ignite the fuel-air mix. Between the heat, normal wear and tear, and moisture, spark plugs may fail over time and not start the engine as they should.
Ideally, at least once per year, take the spark plug(s) out and evaluate them for signs of any of the following:
- Black deposits
- Erosion or damage
- Rust
- Oil deposits
- Cracks or chips
- Too little or too much of a distance between the electrodes (Could cause an inconsistent or weak spark)
Whenever any of the signs are present, replace the spark plug. If no indication of damage is visible, you may clean it and place it back in.
Change the Oil Regularly
The motor in your generator has moving parts that require oil to keep everything working as it should. The components may wear out prematurely if you don’t adequately lubricate them — making checking and changing the oil regularly a necessity.
To check it, first find the dipstick or cap, usually located on the side of your generator’s motor. Once found, wipe it down to prevent any dirt from entering the oil reservoir.
Then, pull out the stick, and use a paper towel to wipe it off. Next, dip the stick into the reservoir, and pull it back out. The level should be between the “low” and “full” marks. If there’s enough and it doesn’t appear darker than normal, gritty, or thick, you’re good to go. However, you’ll need to top off the oil if it’s low. Anytime the oil is discolored, viscous, or contaminated, change it.
Run Your Generator Periodically
You may not use your generator much, which can impact its performance. And when you need it most, you might find it won’t work if you’re not using it regularly.
To ensure your generator works and will continue to do so, start it every few months, and run it on a light load (about 30% of its full capacity) for about 15 to 30 minutes.
Once per year, let it run for that same length of time on a 50-75% load.
Your generator will be ready for the next storm if you properly maintain it, which means changing the oil and spark plugs and running it occasionally. If you need any other helpful hints to keep your generator functioning, read your generator’s manual or consult with a licensed electrician.
