How To Start a Generator: Quick Setup Guide

Portable generators give you the freedom to have reliable power on demand. Learn how to safely set up, use, and maintain your power generator, and it will be ready to use every time you need it.

How to Start a Generator

Step 1: The Critical Safety & Preparation Checklist

Your safety and the integrity of your home are paramount. Before you begin, always follow these non-negotiable guidelines:

• Consult Your Manual: Every piece of equipment is unique. Always consult your owner's manual to ensure proper assembly and to confirm the exact starting procedures for your specific model.
• Location, Location, Location: Never run your generator indoors, in a garage (even if open), a shed, or a partially enclosed area. Carbon monoxide is an odorless, invisible, and deadly gas. Place the generator at least 15 feet away from your home, doors, and open windows.
• Inspect for Damage: Check your generator for any visible damage or signs of a natural gas leak near the intended operating area before fueling.
• Fuel Quality: You must use fresh gasoline. Over time, ethanol in gas absorbs water, causing the fuel to become "stale." Stale gasoline is not only difficult to start but can also permanently damage the engine.
• Protection from the Elements: Generators are not waterproof. To run the unit during a storm, you must use a specialized cover like a gentent to protect it from direct rain while ensuring adequate airflow.
• Refueling Protocol: Always turn the unit off and allow it to cool for 30 minutes to one hour before adding fuel. Hot fumes can ignite.
• The Law & Your Safety: DO NOT attempt to "back feed" your generator by plugging it into a standard wall outlet. This is illegal, extremely dangerous for utility line workers, and a serious fire hazard for your home.

Step 2: Starting the Generator (No Load)

A quick check and correct sequence ensure smooth startup:

1.   Check Fuel and Oil: Verify you have fresh gasoline, and the oil is filled up to the line specified on the generator.

2.   Clear the Deck: Ensure all cords are disconnected. You must start your generator before connecting any load.

3.   Fuel and Choke: Turn the fuel valve on (to allow fuel to travel to the carburetor) and pull the choke out.

4.   Ignition and Start:

• Flip the ignition (or engine) switch to the "on" position.
• If using the recoil cord, pull it until you feel resistance and then let it return.

5.   Troubleshooting Tips:

• If the engine doesn't start, move the choke to the "half run" position and pull the recoil cord again.
• If you have an electric start generator and it won't fire, the battery may be dead. You can charge it on a trickle charger.

6.   Warm-Up: Once the engine is running, push the choke back into the "run" position to let the engine come up to full operating speed. Allow the generator to run for 3 to 5 minutes before connecting any cords.

Step 3: Connecting Your Generator to Your Home

This is where planning and selecting the right products pays off.

Generator Power Cord Details for MTS/Inlet Boxes:

When using a generator power cord, make sure the ends connect correctly:

• The Male end (straight-blade plug) connects to the generator.
• The Female end (connector) connects to the power inlet box outside your home.

Troubleshooting Power Delivery

If you are connected but not getting power:

• Check that the main circuit breakers on the generator are fully depressed and not "popped out."
• Ensure any GFCI outlets on the generator are in the reset position (not the test mode).

Beyond Portable Power

For homeowners or professionals tackling a larger project, consider the efficiency of a home standby generator.

With the installation of a standby generator and an Automatic Transfer Switch (ATS), your generator runs automatically when utility power fails. The need to follow most of the manual starting procedures is eliminated, providing peace of mind and effortless operation.
