Installation & Maintenance Notes

Follow the generator service schedule and service procedures in your generator owner’s manual.

Before Servicing:

• Turn off the generator

• Allow the engine to cool completely

Air Filter: Ensure the new air filter is correctly seated in the housing to maintain clean engine airflow.

Oil Filter: Lightly coat the new oil-filter gasket with clean engine oil and install according to the manufacturer’s specified tightening instructions. This helps remove contaminants from engine oil effectively.

Spark Plugs: Check the generator spark plug gap before installation and tighten to the engine manufacturer’s specified torque for dependable ignition.

After Installation: Refill the engine with the approved oil type and quantity, then inspect the oil-filter area for leakage.

Always verify your generator’s complete model and serial numbers before ordering.
