Installation & Maintenance Notes

Service is commonly recommended every 200 operating hours or every two years, whichever comes first. The required interval may vary by model, operating conditions, and maintenance history. Generators used for extended periods or in dusty environments may require more frequent service.

Before Servicing:

• Turn off the generator
• Disable automatic starting
• Disconnect the battery as directed
• Allow the engine to cool completely

Oil Change: Two quarts are supplied, but the engine may not require the entire amount during an oil change. Always follow the generator owner’s manual for the correct oil capacity. Use the included paper funnel to reduce spills.

Air Filter: Ensure the new air filter is correctly seated in the housing to prevent dirt and debris from entering the engine.

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

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

After Installation: Confirm the oil level, inspect for leaks, and test the generator according to the manufacturer’s instructions before returning it to automatic operation. Apply the maintenance reminder sticker to track your next service date.

Always verify your generator’s complete model number, serial number, production date, engine displacement, and existing maintenance-kit number before ordering.
