1. Engine Oil — The Most Important Routine Service
Checking and changing the engine oil is the most important maintenance step.
Before Each Use
Check the oil level and make sure it is within the recommended range.
First Oil Change
Change the engine oil after:
20 operating hours or 1 month, whichever comes first.
Regular Oil Changes
After the first service, change the oil every:
50 operating hours or 3 months.
Basic Oil Change
- Stop the generator before maintenance.
- Place the generator on a level surface.
- Remove the oil dipstick.
- Remove the oil drain bolt and drain the used oil.
- Reinstall and tighten the drain bolt.
- Add the recommended engine oil.
- Check the oil level.
- Reinstall the dipstick.
2. Air Filter — Easy to Inspect and Clean
A clean air filter helps the engine breathe properly and protects the carburetor and engine from dust.
Routine Care
Check the air filter before every use.
If the foam filter becomes dirty:
- Remove the air filter cover.
- Remove and inspect the filter element.
- Wash it with warm soapy water or an approved non-flammable cleaner.
- Rinse and squeeze it dry.
- Apply a few drops of engine oil to the foam element.
- Reinstall the filter and cover.
Never operate the generator without the air filter installed.
3. Spark Plug — Only Occasional Attention Needed
The spark plug does not require frequent maintenance.
For the tri-fuel 6800PT, use the spark plug specification listed in the owner's manual.
Inspect the spark plug approximately every:
270 operating hours or once per year.
Check for:
- Carbon buildup
- Damaged insulation
- Excessive electrode wear
- Incorrect electrode gap
Clean and adjust the spark plug when appropriate, or replace it if damaged.
Heavy-Duty or Dusty Conditions
More frequent maintenance is recommended when the generator operates under demanding conditions.
High Temperature or Heavy Load
If the generator is frequently operated under high temperature or heavy load conditions:
Change the engine oil every 10 operating hours.
Dusty or Harsh Environments
If the generator is frequently used in dusty conditions:
- Clean the air filter every 10 hours
- Replace the air filter approximately every 25 hours if necessary
Long-Term Storage
Preparing the generator correctly for storage helps prevent fuel-system problems when you need it again.
Before long-term storage:
- Allow the generator to cool completely.
- Store it in a clean, dry location.
- Remove fuel from the gasoline tank.
- Clean the fuel filter components as required.
- Drain remaining gasoline from the carburetor.
- Tighten the carburetor drain bolt after draining.
- Store the generator according to the owner's manual.
This is especially important when the generator will not be used for an extended period.
