Imagine—it’s freezing, you need power fast, but your generator’s not budging. Sounds frustrating, right? Cold weather and generators aren't always the best combination. Even the most reliable Gentrax generator can struggle to start when temperatures drop.
Knowing proper cold start methods can save you a lot of hassle. This guide walks you through the winter generator start procedure step-by-step to safely start your Gentrax inverter generators in cold weather.
Why Cold Weather Affects Generator Start-Up
When temperatures drop, even the best inverter generators need a little extra love. As engine oil thickens, it’s harder for the engine to turn over. Spark plugs may also misfire due to moisture or colder combustion chambers.
Batteries drain faster, reducing the power needed for electric starts. The fuel flow slows down, especially if you’re not using a fresh one. So, knowing how to start a generator in cold weather safely can make all the difference.
Step-by-Step: Starting Your Gentrax Generator in Cold Weather
[Step 1: Move It to a Sheltered, Dry Spot
Can portable generators get wet? No. Cold rain or frost can create electrical hazards, even when manufacturers like Gentrax design generators for the outdoors. Avoid this by keeping your generator on a dry, elevated surface and under a well-ventilated cover or awning.
Step 2: Check Oil and Fuel Levels
Proper oil viscosity helps the engine start and run smoothly. Always use fresh fuel and top up oil levels. If the temperature regularly drops below 0°C, switch to a winter-grade oil. Check your manual for the specific type.
Step 3: Switch to Manual Start Mode (if applicable)
Switching to a manual pull-start mode can help in colder temperatures. Some models, like the Gentrax 3.5 kW Inverter Generator, may respond better to this starting method. It’s more direct and requires less from the battery.
Step 4: Prime the Engine
Prepare the carburettor for ignition by following your Gentrax manual’s instructions. Be careful not to over-prime, as this can cause Gentrax generator problems like flooding the engine, which can make starting harder. A few steady presses are usually all it takes.
Step 5: Pull Start Gently, Then Firmly
Start by slowly and gently pulling to engage the flywheel, then follow up with a firm pull. If you prep your generator properly, three to five attempts should be enough.
Step 6: Let It Warm Up Before Plugging In
Don’t connect devices immediately upon starting. Give the engine at least 2-3 minutes to warm up so the oil can circulate.
Cold-Weather Generator Care Tips
Portable generators aren’t cheap. Here are some cold weather startup tips for home generators to protect your investment:
Store Off the Ground
The ground can expose your generator to frost or wet soil. Always store it off the ground. Consider placing it on a wooden board or rubber mat.
Cover When Not in Use
If you’re not using your generator, cover it up to keep it dry and prevent any debris. Use a weather-resistant cover, one with ventilation slots, to prevent heat or moisture from getting trapped.
Drain Fuel If Not Used Often
Stale fuel clogs carburettors, especially in cold weather. If you’re not using your generator for weeks, empty the fuel tank and run the carburettor dry.
Run Regularly
Inverter generators must be run every couple of weeks, even if briefly. This will keep internal parts lubricated and prevent build-up in the fuel system.

Frequently Asked Questions
Why is it harder to start my Gentrax generator in cold weather?
Cold temperatures thicken engine oil, slow down fuel flow, and reduce battery efficiency. Moisture can also affect spark plugs and combustion. All of this makes starting more difficult—but totally manageable with the right prep.
Can I run my Gentrax generator in the rain or snow?
No. Even though Gentrax generators are built tough, using them in wet conditions can be dangerous. Always operate your generator in a dry, sheltered spot with proper ventilation to avoid electrical hazards.
What oil should I use for my generator in cold weather?
If temperatures drop below 0°C, switch to a winter-grade engine oil with lower viscosity. Check your Gentrax manual for the recommended cold-weather oil type for your specific model.
Should I use the electric or manual start in freezing temperatures?
Manual pull-start is often more reliable in cold conditions since the battery can lose charge in low temps. For models like the Gentrax 3.5kW inverter generator, switching to manual mode can help get things going faster.
How long should I let my generator warm up before plugging anything in?
Let it run for at least 2–3 minutes before connecting devices. This gives the engine and oil time to reach optimal operating temperatures and ensures stable output.
How do I store my Gentrax generator during winter?
Store it off the ground, ideally on a wooden or rubber surface. Cover it with a breathable, weather-resistant generator cover. If unused for weeks, drain the fuel and run the carburettor dry to prevent clogging.
