Preparing Your Generator for Storage

Before storing a generator for a while, you’ll want to ensure it’s in prime condition for the next use.

1. Start by running the generator for a short period (15-20 minutes) to make sure everything’s functioning correctly. This process also helps burn off any remaining fuel, which is key in preventing issues related to old gasoline.
2. Change the oil and oil filter (12,000-watt units and above only). Old oil can contain particles that might cause engine wear if left unattended. By swapping out the oil, you help protect the engine’s internal components and maintain smooth operation.
3. Clean the air filter. A clean air filter is vital for proper engine function, as it ensures the engine receives the right amount of clean air. If the filter’s clogged or dirty, it can restrict airflow, reducing efficiency and possibly harming the engine. So, take a few minutes to clean or replace it as needed.
4. Clean your portable generator’s spark arrestor. If the arrestor contains too much carbon buildup, engine performance will hinder, can surge, or experience power loss. Keeping it clean also helps prevent fire hazards.

By following these steps, you’ll set yourself up for successful generator storage and reliable future use.

Pre-Storage Cleaning and Maintenance

Cleaning and maintenance are crucial before you tuck your generator away for an extended period.

1. Wipe off any debris from the exterior using a soft cloth. Pay special attention to the air intake and exhaust areas to prevent blockages. A clean surface not only looks good but also helps you spot any potential issues that might need fixing.
2. Check for signs of wear or damage as well. Inspect the generator’s casing, fuel lines, and electrical connections for any cracks or fraying. Addressing these issues before storage can save you from headaches down the road. If you spot significant damage, consult your generator’s owner’s manual for advice on repairs or replacements.
3. Apply a protective spray to ward off rust and corrosion. A good rust inhibitor can be valuable, especially if your generator will be in a humid area. This little step goes a long way in maintaining your generator’s condition.

By taking care of these cleaning and maintenance tasks, you ensure your generator remains in great shape, ready for whatever comes next. For a full guide on generator maintenance*, check out our generator maintenance checklist.

Safe Generator Storage Best Practices

When it comes to generator storage, location is crucial. Choose a dry, cool spot away from direct sunlight, like a well-ventilated garage or shed. Avoiding excessive heat and humidity helps protect your generator’s components and fuel system.

Before storing your generator, make sure the gas valve is closed and use a generator gas stabilizer. A generator gas stabilizer prevents gasoline from deteriorating, which could lead to hard starts or engine troubles later. Run the generator for a few minutes with the stabilizer so the whole system benefits. Let it cool completely before stowing it away.

Consider covering your generator to shield it from dust and moisture with a protective cover for portable generators or inverters. A quality cover keeps your generator safe from environmental hazards, helping to maintain its appearance and functionality.

Lastly, is it safe to store a generator in a garage? The answer is yes, as long as it’s well-ventilated and the generator is cool before storage. This ensures safe and effective generator storage.

Generator Storage Locations

Knowing where to store a generator when not in use is crucial for its longevity. A well-ventilated garage or a dedicated storage shed can be ideal locations, provided they are dry and shielded from direct sunlight. Proper generator storage not only keeps your equipment in working order but also ensures safety.

By storing a generator in a location that meets these conditions, you minimize the risk of damage from environmental factors. Always remember to use a generator gas stabilizer to maintain fuel quality, and routinely check the condition of your generator to prevent long-term issues.

Portable and standby generators provide reliable backup power, but understanding generator safety is crucial to protect people, property, and equipment. Use this guide to learn about key hazards, such as carbon monoxide risks, and how to use a generator safely. Whether you’re a seasoned portable generator user or are considering purchasing your first unit, we’ll provide portable generator safety tips that apply to many setups.

Understanding Generator Safety

Improper generator use can lead to carbon monoxide (CO) poisoning, electric shock, fire from fuel or hot surfaces, and mechanical injury. Many incidents occur during outages when equipment is quickly set up without proper ventilation or electrical safeguards. Focusing on generator safety precautions from the start helps you avoid these pitfalls.

Following the manual, using approved accessories like Storm Shields for wet weather, and planning your setup in advance dramatically reduces risk. Always operate a portable generator outdoors in an open area on a flat, level surface away from any windows or doors and install working CO alarms. Reports indicate that CO-related injuries and fatalities linked to portable generators during storms and cold snaps are often preventable with correct placement and ventilation. If evaluating generators for rent, ensure you understand the unit’s fuel type, output, and safety features before use.

Carbon Monoxide Awareness

Carbon monoxide is a colorless, odorless gas created by fuel-burning engines. Even low levels can make you sick; higher concentrations can be fatal within minutes. Because CO is undetectable by smell or sight, rely on proper placement and functioning CO alarms. Champion’s CO Shield* technology provides added safety by automatically turning off the portable generator should it detect dangerous levels of CO. Note: CO Shield is not a substitute for an indoor carbon monoxide alarm or for safe operation.

Generator safety precautions are key to generator safety:

• Symptoms: headache, dizziness, nausea, confusion, weakness, and chest pain. Severe exposure may cause loss of consciousness.
• If exposure is suspected: move to fresh air immediately and call emergency services.
• Prevention: run generators only outdoors, at least 20 feet from windows, doors, and vents, with the exhaust directed away from the building. Never operate in garages, basements, crawlspaces, or enclosed porches—even with doors open.
• Install battery-powered or hardwired CO alarms on every level of your home and test them regularly.

Safe Operating Procedures

Do

• Read the owner’s manual before use and follow all labels.
• Use heavy-duty, outdoor-rated extension cords with intact grounding.
• Keep the unit dry on a stable, level surface; use Storm Shields in wet weather.
• Refuel only when the engine is off and cool; store fuel in approved containers.

Don’t

• Do not run a generator indoors, in a garage, or under a carport.
• Avoid backfeeding the home through a wall outlet.
• Do not overload circuits or exceed rated wattage.
• Do not operate near combustible materials or block airflow around the unit.

Correct placement and ventilation are essential. Position the generator outdoors with at least 20 feet of clearance from openings and aim the exhaust away from structures. In rain or snow, use a Storm Shield designed for generator operation that maintain airflow and keep the unit dry.

Regular maintenance supports safety and reliability. Follow oil change intervals, inspect and replace air filters as needed, check fuel lines for cracks, test GFCI outlets, and run the generator periodically for at least 15 minutes. Replace worn cords and verify all connections are tight and undamaged.

Emergency Preparedness

Plan ahead for outages. Identify where the generator will sit, how it will connect to essential loads, and how you will store and rotate fuel. Keep a kit with spare oil, filters, spark plugs, and approved fuel containers. Confirm CO alarms work and inspect extension cords before each use. These steps reinforce portable generator safety when it matters most.

To power household circuits safely, use a professionally installed manual transfer switch or interlock kit that isolates your electrical system from the utility grid. This prevents backfeeding a generator, protects utility workers, and ensures the generator supplies only selected circuits. Never attempt to power your home by plugging the generator into a receptacle.

During severe weather, secure the generator on a stable surface, use a Storm Shield in wet conditions, and monitor wind direction to keep exhaust moving away from the home. Manage noise considerations, keep a fire extinguisher nearby, and always shut down and cool the unit before refueling. Prioritize these portable generator safety tips over convenience whenever you operate a generator, whether it’s your own unit or one sourced from renting.
