Fall Is Coming to Pennsylvania. Is Your Generator Ready?
Key Maintenance & Operational Practices to Keep It Running Strong
As Philadelphia gears up for shorter days, dropping temps, and the occasional surprise storm, your generator becomes more than a backup, it’s a lifeline. Whether you rely on it for home comfort, worksite power, or peace of mind, proper care is what keeps it humming when the lights go out.
Here’s your no-fluff guide to prepping your generator for the colder months and keeping it in peak shape all year round.
1. Stay on Top of Routine Maintenance
Oil & Filter Changes
Your engine’s health starts with clean oil. Change the oil every 50–200 hours of use or at least once a year, depending on how often you run it. And don’t forget: always replace the oil filter when you change the oil.
Air Filters & Spark Plugs
Dust, debris, and dirt are your generator’s enemies. Replace the air filter as needed (especially if you’re in a rural or dusty area). Check spark plugs every 100 hours or annually.
Battery & Fuel System
Each month, inspect and clean your battery terminals, check the charge, and monitor electrolyte levels. Replace batteries every few years. Also, check fuel lines and filters regularly—and if your generator will sit for a while, add a fuel stabilizer to keep the fuel fresh.
2. Use It or Lose It: Regular Usage & Load Management
Run It Monthly
Don’t wait for an emergency to find out your generator’s not working. Run it for 30 minutes once a month under load to lubricate internal components, charge the battery, keep fuel circulating, and spot early issues.
Avoid Babying It
Running under a light load, especially in diesel units, can cause carbon buildup. Instead, aim for at least 70% of rated capacity during tests to keep it in fighting shape.
Do a Load Bank Test
Once a year, conduct a load bank test. It’ll push your generator to its limits, burn off carbon, and expose any hidden performance issues.
3. Mind Your Start-up and Shutdown Procedures
Cool It Down
After running under load, remove the load and let your generator idle for 3–5 minutes before shutting down. This helps normalize internal temperatures and extends engine life.
Stick to SOPs
Using consistent startup and shutdown routines reduces wear and tear. Treat your generator like a tool, not a toy.
4. Smart Storage & Fuel Care
Keep It Clean & Covered
Store your generator in a dry place with a breathable, weather-resistant cover to keep out moisture and dust. Moisture leads to corrosion, don’t let it sneak in.
Fuel Stabilizer or Drain It
If the generator will sit unused for more than a month, add a stabilizer and run the unit briefly to circulate it. Or, drain the fuel entirely for long-term storage.
Mothballing Tips
Many experienced operators recommend a full mothballing before long storage: drain fuel, change oil, clean everything, and cover properly.
Watch the Slip Rings
Even when idle, slip rings can rust. A quick run every few weeks helps prevent corrosion in these critical parts.
5. Inspect, Monitor & Repair Promptly
Look for Trouble
Do regular visual inspections. Check for leaks, cracked hoses, corrosion, loose connections, and any signs of overheating or wear.
Use Quality Fluids
Cheap oil or fuel can cause costly damage. Stick with high-grade oil, coolant, and fuel for optimal performance and longevity.
Don’t Delay Repairs
A tiny leak today can become a major breakdown tomorrow. Fix small problems fast before they grow.
6. Call in the Pros Once a Year
Get a Pro Inspection
At least once a year, schedule a visit from a qualified technician. They’ll do a full inspection, fluid analysis, diagnostics, load testing, and ensure you stay compliant with any warranty requirements.
Don’t Wait for the Storm
Philadelphia area fall weather can be unpredictable. Now’s the perfect time to give your generator the care it deserves before the first frost or outage hits. A little preventative maintenance now can save you hours of stress (and cold) later.
