Generator Maintenance Schedule: Keep Your Backup Ready Year-Round
Oil, filters, batteries, exercise cycles, and load bank testing — the maintenance checklist that prevents failed starts during storms.
A standby generator that never exercises or gets its oil changed is a very expensive garden statue. Most failed starts we see in Waco after storms come down to dead batteries, dirty filters, stale fuel (portables), or ignored fault codes — all preventable with a simple maintenance schedule.
Maintenance Essentials
Oil & filters
Follow manufacturer intervals — often yearly or every 100–200 run hours. Texas heat is hard on oil.
Battery health
Weak batteries are the #1 no-start cause. Test annually; replace every 2–3 years typically.
Exercise cycles
Weekly exercise keeps seals lubricated and proves the starter works. Verify it actually ran.
Controller faults
Don't ignore yellow lights. Small sensor issues become dark-house problems during outages.
Fuel quality (portable)
Stabilize gasoline or run dual-fuel. Stale gas gums carbs after storage.
Transfer gear checks
Confirm clean transfer operation during service — not only engine health.
Load bank / load test
Periodic loaded tests reveal problems that no-load exercise can miss.
