How to Maintain Your 4500 Watt Inverter Generator

Maintaining your 4500 Watt inverter generator is essential to keep it running smoothly for years to come. Proper maintenance can also prevent costly repairs down the line. Here are a few tips to help you maintain your generator:

Regular Oil Changes

Regular oil changes are crucial to keep your generator running efficiently. Check the oil level before each use and change the oil after every 50 hours of use or as recommended by the manufacturer. Use the recommended oil type and viscosity for your generator.

Air Filter Maintenance

The air filter prevents dust and debris from entering the engine and causing damage. Clean the air filter after every 25 hours of use or as recommended by the manufacturer. Replace the air filter if it is damaged or excessively dirty.

Fuel System Maintenance

Keep the fuel system clean by using fresh fuel and adding a fuel stabilizer if the generator will not be used for an extended period. Drain the fuel tank and carburetor if the generator will not be used for more than a month.

Spark Plug Maintenance

The spark plug ignites the fuel in the engine. Check the spark plug after every 100 hours of use or as recommended by the manufacturer. Replace the spark plug if it is damaged or worn out.

Battery Maintenance

If your generator has a battery, keep it charged by running the generator for a few hours every month or as recommended by the manufacturer. Check the battery terminals for corrosion and clean them if necessary.

General Maintenance

Inspect the generator for any damage or loose parts before each use. Keep the generator clean and dry. Store the generator in a safe, dry place when not in use.
