1. Initial Setup: The First Start-Up Checklist

Add Engine Oil (Crucial Step)

New generators are shipped without oil. This is the most critical step on your generator maintenance checklist. Locate the oil fill port (often with a yellow cap) and add the recommended oil type (typically 10W-30). Running the engine dry will cause immediate, irreparable damage.

Connect Grounding Wire

For safety, connect the generator’s grounding bolt to a suitable ground rod. This is a vital step for preventing electric shock during operation.

Add Fresh Fuel

Use fresh, unleaded gasoline. Avoid ethanol-heavy gas where possible, and never use fuel that has been stored for more than 30 days. Old fuel is the enemy of a smooth new generator oil break-in.

2. Routine Generator Maintenance TipsOil Change Schedule

Oil Change Schedule

Change the oil after the first 20 hours of operation (the essential "break-in" period), and then every 100 hours of runtime thereafter. This simple habit protects your engine investment.

Spark Plug and Air Filter

Inspect the spark plug annually or every 100 hours—a clean spark plug ensures easy starting. Also, clean or replace the air filter periodically, especially if operating in dusty conditions. A clogged filter reduces efficiency and power output.
