Proper storage of an ‌open frame type generator set‌ is crucial to maintain its performance and extend its service life. Unlike enclosed models, the exposed design of ‌open frame type generator sets‌ requires special attention to protect critical components from environmental damage. Below are essential storage guidelines to ensure your equipment remains in optimal condition during periods of inactivity.

1. Choosing the Right Storage Location‌

Store the ‌open frame type generator set‌ in a clean, dry, and well-ventilated area to prevent moisture buildup and corrosion.

Avoid locations with extreme temperature fluctuations, as this can damage electrical components and fuel systems.

If outdoor storage is unavoidable, use a waterproof cover that allows air circulation to prevent condensation.

 

2. Preparing the Generator for Storage‌

Fuel System Maintenance:‌

Add a fuel stabilizer to the tank and run the generator for a few minutes to circulate treated fuel through the system.

For long-term storage, consider draining the fuel tank and carburetor to prevent gum formation.

Oil Change:‌ Replace the engine oil to remove contaminants that could cause internal corrosion during storage.

Battery Care:‌ Disconnect the battery and store it in a cool, dry place. Maintain charge levels with a trickle charger if necessary.

 

3. Protecting Critical Components‌

Cover exposed electrical connections with dielectric grease to prevent oxidation.

Seal the air intake and exhaust openings with protective caps or plastic covers to keep out dust and pests.

Lubricate moving parts such as hinges and control linkages to prevent rust and ensure smooth operation when reactivated.

4. Proper Positioning and Security‌

Store the ‌open frame type generator set‌ on a level surface to avoid oil leaks or uneven weight distribution.

Elevate the unit on pallets or blocks if stored in areas prone to flooding or excessive moisture.

Secure the generator against theft or unauthorized use, especially in unmonitored locations.

 

5. Periodic Maintenance During Storage‌

Inspect the generator monthly for signs of moisture, rust, or pest infestation.

Crank the engine manually every few months to prevent bearing damage and ensure components remain lubricated.

Check protective covers and replace them if damaged to maintain proper shielding from environmental elements.

 

6. Reactivation After Storage‌

Before returning the ‌open frame type generator set‌ to service:

Remove all protective covers and inspect for rodent nests or debris.

Reconnect the battery and check electrolyte levels if applicable.

Refill fluids and test the generator under no-load conditions before applying full operational loads.

 

By following these storage practices, users can significantly reduce the risk of damage and ensure their ‌open frame type generator set‌ remains ready for reliable operation when needed. Proper care during idle periods preserves the equipment's value and minimizes costly repairs, making it a worthwhile investment for long-term use. Always consult the manufacturer's guidelines for model-specific storage recommendations.
