Setting Up Your New Duromax Generator

Proper setup is crucial to ensure your Duromax generator operates safely and efficiently. Follow these steps when setting up your new generator for the first time:

Choose a suitable location: To avoid carbon monoxide poisoning, place the generator outdoors on a flat, level surface at least 20 feet away from windows, doors, and vents. Ensure the area is well-ventilated and protected from rain and snow.
Check the oil: Unscrew the oil fill cap and check the oil level using the dipstick. If needed, add the recommended oil type (usually SAE 10W-30) until it reaches the full mark on the dipstick. Be careful not to overfill.
Add fuel: Use fresh, clean gasoline with an octane rating of 87 or higher. Avoid using gasoline containing more than 10% ethanol. Fill the tank to about 1/4 inch below the top to allow for fuel expansion.
Ground the generator: Drive a copper grounding rod at least four feet into the earth near the generator. Attach a grounding cable (at least 10 gauge) to the generator’s grounding terminal and the rod.
Connect the battery (if applicable): Some Duromax models have an electric start feature that requires a battery. Connect the positive (red) cable to the battery’s positive terminal and the negative (black) cable to the negative terminal.
Turn the fuel valve on: Locate the fuel valve and turn it to the “on” position to allow fuel to flow to the carburetor.
Set the choke: If your generator has a choke lever, set it to the “closed” position when starting a cold engine. Once the engine warms up, move the choke to the “open” position.
Start the generator: For a recoil start, firmly grasp the starter cord handle and pull it slowly until you feel resistance. Then, pull the cord rapidly and smoothly. For an electric start, turn the key to the “start” position until the engine runs, then release.
Let the engine warm up: Allow the generator to run for a few minutes before connecting any appliances or equipment. This helps stabilize the engine’s speed and voltage output.
Connect your devices: Plug your appliances into the generator’s outlets, being mindful not to exceed the generator’s wattage capacity. Use heavy-duty, outdoor-rated extension cords to connect devices.

By following these setup steps, you’ll ensure your Duromax generator is ready to provide reliable power when you need it most. Remember to read your model’s owner’s manual for specific instructions and safety guidelines.
