Home Generator Maintenance, Test, Fuel, and Outage Log Template

Portable and permanently installed generators have different operating and maintenance requirements. Every interval and procedure should come from the exact manufacturer manual.

What to know

  • Portable and permanently installed generators have different operating and maintenance requirements. Every interval and procedure should come from the exact manufacturer manual.
  • Record every inspection, test, fuel change, maintenance event, operating hour, and outage.

Create one permanent record for each generator.

Never operate a portable generator indoors, in a garage, basement, crawlspace, shed, porch, or carport.

Operate it outdoors at least 20 feet from homes and other occupied structures, with exhaust directed away from doors, windows, and vents.

Do not apply a portable-generator schedule to an automatic standby generator or vice versa.

CO alarms tested:

Never connect a portable generator to household wiring through an ordinary receptacle.

Backfeeding can energize utility lines, damage equipment, and expose workers or neighbors to lethal voltage.

Use approved transfer equipment installed according to code and manufacturer instructions.

Pre-use inspection

| Item | Result | Action | |---|---|---| | Fuel leak | | | | Oil level | | | | Air filter | | | | Cord and receptacle | | | | Battery | | | | Exhaust | | | | CO shutoff | | | | Fasteners | | | | Damage | | | | Clear operating area | | |

Do not operate a generator with a fuel leak, damaged wiring, missing panel, cracked tank, abnormal battery, fire damage, flood exposure, or burning odor.

Maintenance schedule

| Service | Manual interval | Last completed | Hours | Next due | Performed by | |---|---|---|---:|---|---| | Engine oil | | | | | | | Oil filter | | | | | | | Air filter | | | | | | | Spark plug | | | | | | | Valve clearance | | | | | | | Battery | | | | | | | Fuel system | | | | | | | Cooling vents | | | | | | | Transfer equipment | | | | | |

Use the exact owner’s manual. Do not copy one internet maintenance table onto every engine.

Fuel record

Fuel type:
Container:
Purchase date:
Stabilizer:
Stabilizer date:
Stored quantity:
Storage location:
Rotation date:
Disposal route:

Store fuel in approved containers, away from ignition sources and occupied living areas, according to local fire code.

Never refuel a running or hot generator.

Fuel stabilizer can extend storage life but cannot restore gasoline that is already stale.

Scheduled test

| Date | Start method | No-load result | Test load | Voltage | Frequency | Runtime | Fault | |---|---|---|---|---|---|---|---| | | | | | | | | |

For a planned test:

  1. Move a portable generator to its approved outdoor location.
  2. Inspect it.
  3. Confirm CO alarms work.
  4. Start it according to the manual.
  5. Allow stabilization.
  6. Apply an approved test load.
  7. Observe for leaks, smoke, noise, or faults.
  8. Remove loads.
  9. Stop it normally.
  10. Record the result.

Do not run a gasoline generator inside because the test is short. Carbon monoxide is not impressed by limited scheduling.

Outage-operation record

Outage start:
Generator start:
Fuel at start:
Equipment powered:
Total load:
Refueling times:
Operating hours:

CO alarms:

Fuel used:
Problems:

Never exceed running watts, surge watts, outlet rating, cord rating, or transfer-equipment rating.

Cleaning

Use the exact approved cleaning method.

Keep cooling openings clear, controls dry, dirt away from fuel fill, and combustibles away from exhaust.

Do not use a garden hose unless the manual explicitly permits it. Water can damage engine and generator windings.

Standby generators

Record:

  • Automatic exercise date
  • Exercise result
  • Battery condition
  • Fuel supply
  • Dealer service
  • Fault code
  • Remote-monitor status
  • Transfer-switch service

A successful weekly exercise does not prove the home can carry the intended outage load.

Bottom line

Record every inspection, test, fuel change, maintenance event, operating hour, and outage.

The generator should be boring before the emergency. Discovering stale fuel, a dead battery, missing adapter, and an untested transfer switch after the lights go out is a more cinematic experience than the household needs.
