Winterizing Portable Generators For Storage

As winter approaches, it’s crucial to properly prepare your portable generator for storage to ensure it remains in top condition and ready for use when you need it most. Winterizing your generator protects your investment and guarantees reliable performance when power outages strike.

This guide will walk you through the essential steps to winterize your portable generator for storage.

Understanding Portable Generators

Before diving into winterization, it’s important to have a solid grasp of how portable generators work. This knowledge will help you better understand the importance of each step.

Cleaning and Inspection

Start the winterization process by thoroughly cleaning your generator’s exterior. Use a damp cloth to remove dirt, dust, and debris. Pay special attention to the cooling fins, air intakes, and exhaust ports. Once clean, carefully inspect the generator for any signs of damage, wear, or loose connections. Address any issues before storage to prevent them from worsening over time.

Fuel System Preparation

Proper fuel system care is critical for winter storage. Begin by draining the fuel tank completely. Run the generator until it’s entirely out of fuel for optimal protection. Alternatively, add a fuel stabilizer to fresh gasoline and run the generator for a few minutes to distribute the treated fuel throughout the system. This step prevents fuel degradation and carburetor clogging.

If your generator has been running on old fuel, consider cleaning the carburetor to remove any buildup that could cause starting problems in the spring.

Oil and Filter Maintenance

Change the oil in your generator before storage. Old oil can contain contaminants that may damage engine components over time. While you’re at it, replace or clean the air filter to ensure proper airflow when you start the generator again. Check the spark plug and replace it if necessary to guarantee easy starting after storage.

Battery Care

Battery care is essential for generators with electric start. Disconnect and remove the battery, clean the terminals, and store it in a cool, dry place. Consider using a trickle charger to maintain the battery’s charge during long-term storage.

Protecting Against Moisture and Pests

Moisture is a generator’s enemy during storage. Use moisture-absorbing products like silica gel packets inside the generator housing. Cover air intakes and exhaust ports with tape or plastic wrap to prevent pests from making homes inside your generator. Store the generator in a dry, elevated location to protect it from potential flooding or moisture accumulation.

Storage Location Considerations

Choose a cool, dry place for storage, such as a garage or shed. Ensure the area has proper ventilation to prevent moisture buildup. Avoid storing the generator in areas subject to extreme temperature fluctuations, as this can lead to condensation inside the engine.

Pre-Storage Test Run

Before finalizing storage, run the generator briefly to ensure all systems function correctly. This test run can help identify any issues that need addressing before long-term storage.

Periodic Maintenance During Storage

Even in storage, your generator needs attention. Perform monthly check-ups to ensure everything remains in good condition. Consider running the generator for a short period every few months to keep internal components lubricated and prevent seals from drying out.

Preparing for Spring Use

When it’s time to bring your generator out of storage:

• Reinstall the battery if applicable
• Refuel with fresh gasoline
• Perform a final inspection before use
• Check all fluid levels and connections to ensure everything is in order

Conclusion

Properly winterizing your portable generator for storage is an investment in its longevity and reliability. By following these steps, you’ll ensure that your generator is ready to provide power when you need it most, whether during a winter storm or for your spring and summer activities. Remember, well-maintained generators are more reliable; taking the time to winterize properly will pay off in the long run.

FAQS

Why is it important to winterize a portable generator before storing it?

Winterizing a portable generator before storage is crucial because:

• Cold weather can damage various components if the generator isn’t prepared
• Proper winterization prevents rust, corrosion, and other deterioration during storage
• It ensures the generator will start smoothly and run well when needed after storage

What are the key steps to winterize a portable generator?

The main steps to winterize a portable generator for storage include:

• Cleaning the generator thoroughly and inspecting it for any damage
• Changing the oil to prevent sludge buildup and keep it flowing smoothly
• Draining the fuel tank and carburetor to avoid stale fuel and clogging
• Checking the battery and using a battery tender to maintain its charge

Where should I store my portable generator during the winter months?

When storing your portable generator for the winter, choose a location that is:

• Cool and dry to prevent moisture damage and rust
• Well-ventilated to avoid any dangerous fume buildup
• Protected from direct weather elements like rain and snow
• Secure and out of reach of children or pets

Is it necessary to run my generator periodically during winter storage?

Yes, it’s a good idea to start and run your portable generator every few months while it’s in storage. This keeps the engine lubricated, prevents parts from seizing up, and ensures the generator will be ready to operate when you need it.

How often should I charge my generator’s battery during winter?

If you’re storing your portable generator for an extended period without use, it’s best to connect the battery to a battery tender or trickle charger. This maintains the battery’s charge level and prevents it from draining or deteriorating. Check the battery every month to ensure it stays properly charged.

What can happen if I don’t winterize my portable generator before storage?

Failing to winterize your portable generator before winter storage can lead to several problems:

• Moisture can cause rust and corrosion on metal parts
• Stale fuel can clog the carburetor and fuel lines
• Oil can thicken and cause engine damage upon startup
• The battery may drain completely and be unable to start the generator
• Pests could nest inside and chew on wires or other components

Can I store my portable generator with fuel in the tank over winter?

It’s best to drain the fuel tank and carburetor before winter storage. Over time, fuel can degrade and form gummy deposits that clog the fuel system. If you do store the generator with fuel, add a fuel stabilizer to prevent deterioration and make sure to run the generator regularly.
