How to Turn on a Gas Lawn Mower?

Spring has sprung, the sun is shining, and your lawn is begging for a trim. But before you can tackle that overgrown grass, you need to master the art of starting your gas lawn mower. This seemingly simple task can feel daunting for a first-timer, but don’t worry! This guide will walk you through the steps, from preparing your mower to troubleshooting any potential hiccups, leaving you confident and ready to mow.

Essentially, starting a gas lawn mower is a two-step process: 1) preparing the mower and 2) starting the engine. We’ll delve deeper into each stage, breaking it down into clear, actionable steps.

Preparing Your Gas Lawn Mower

Before you can even think about turning your mower on, you need to ensure it’s ready to go. This involves a few basic checks and preparations.

1. Fuel Up

The first step is to make sure your mower has fuel. Gas lawn mowers require a specific blend of gasoline and oil, which is typically 87 octane unleaded gasoline mixed with two-cycle oil. The ratio of gas to oil varies depending on the mower model, so consult your owner’s manual for the correct mix.

Important Considerations:

  • Fresh Fuel: Always use fresh gas for your lawnmower. Old fuel can gum up the engine and lead to starting problems.
  • Storage: If you haven’t used your mower in a while, it’s a good idea to drain the old fuel before adding fresh fuel.
  • Fuel Tank Location: The fuel tank location varies by mower model. It’s usually found on the side or top of the mower.

2. Check the Oil Level

Gas lawn mowers require oil to lubricate the engine parts. Before starting your mower, check the oil level using the dipstick.

Procedure:

  • Locate the dipstick on the engine.
  • Pull it out and wipe it clean with a rag.
  • Re-insert the dipstick fully.
  • Pull it out again and check the oil level. The oil level should be between the “Full” and “Low” markings on the dipstick.
  • If the oil level is low, add more oil using the oil fill cap.

3. Inspect the Spark Plug

The spark plug is crucial for igniting the fuel-air mixture in the engine. A dirty or faulty spark plug can make it difficult to start your mower.

Procedure:

  • Locate the spark plug on the engine. It is usually located near the top of the engine, covered by a wire boot.
  • Disconnect the wire boot.
  • Use a wrench to loosen and remove the spark plug.
  • Inspect the spark plug. It should be clean and free of carbon buildup. If it’s dirty, clean it with a wire brush. If it’s damaged, replace it.
  • Reinstall the spark plug, tightening it to the proper torque.

4. Clear the Mower Deck

Before starting, make sure the mower deck is clear of any debris.

Procedure:

  • Remove any grass clippings, twigs, or other objects from the mower deck.
  • Check for any obstructions around the blades.
  • Ensure the blade is sharp and free of damage.

Starting Your Gas Lawn Mower

Now that your mower is prepped and ready, you can begin the exciting part: starting the engine.

1. Prime the Engine

Priming the engine helps ensure it has enough fuel to start.

Procedure:

  • Locate the primer bulb on the carburetor. It is usually a small, red or yellow bulb.
  • Press the primer bulb several times until it feels firm. This will fill the carburetor with fuel.

2. Engage the Choke

The choke helps enrich the fuel-air mixture, making it easier for the engine to start, especially when cold.

Procedure:

  • Locate the choke lever. It is typically a lever on the side of the engine.
  • Move the choke lever to the “choke” position.

3. Start the Engine

With the engine prepped, you’re ready to start it.

Procedure:

  • Make sure the mower is on a flat surface.
  • Hold the mower firmly in place.
  • Pull the starter rope firmly and quickly.
  • Continue pulling the rope until the engine starts.

Troubleshooting:

If the engine doesn’t start on the first try, don’t panic. Here are some common problems and solutions:

  • No Fuel: If you haven’t recently added fuel, make sure the gas tank is full and that the fuel line is connected.
  • Dead Battery: If your mower has an electric start, the battery might be dead. Charge the battery or use jumper cables to start the mower.
  • Clogged Air Filter: A clogged air filter can restrict airflow to the engine, making it difficult to start. Replace the air filter.
  • Old Fuel: Old fuel can cause starting problems. Drain the old fuel and add fresh fuel.
  • Flooded Engine: If you’ve tried starting the engine several times and it’s not starting, it might be flooded. To clear a flooded engine, turn the choke off, open the throttle, and pull the starter rope several times.
  • Faulty Spark Plug: If the spark plug is faulty, the engine won’t start. Replace the spark plug.

Running Your Gas Lawn Mower

Once you’ve successfully started your mower, you’re ready to tackle your lawn.

1. Engage the Cutting Blades

The blades are controlled by a lever or switch, which you’ll need to engage before you start mowing.

Procedure:

  • Locate the blade engagement lever or switch.
  • Move the lever or switch to the “engage” position.

2. Adjust the Cutting Height

Most gas lawn mowers offer adjustable cutting heights.

Procedure:

  • Locate the cutting height adjustment lever or knob.
  • Adjust the height to your desired level.

3. Start Mowing

You’re ready to mow! Always wear safety glasses and appropriate footwear while operating your lawnmower.

Tips:

  • Overlapping: Overlap each pass by a few inches to ensure even cutting.
  • Safety First: Never mow while wearing loose clothing or jewelry.
  • Avoid Obstacles: Be aware of any obstacles in your path, such as trees, rocks, or sprinkler heads.

Shutting Down Your Gas Lawn Mower

Once you’ve finished mowing, it’s essential to shut down your mower properly.

1. Disengage the Blades

Before turning off the engine, disengage the blades.

Procedure:

  • Move the blade engagement lever or switch to the “disengage” position.

2. Turn Off the Engine

To turn off the engine, you’ll need to locate the engine stop switch.

Procedure:

  • Locate the engine stop switch.
  • Move the switch to the “off” position.

3. Allow the Engine to Cool

Let the engine cool down before putting the mower away.

Why:

  • Allowing the engine to cool down prevents heat damage.
  • It’s also a good time to clean any debris off the mower deck.

Conclusion

Turning on a gas lawn mower might seem intimidating at first, but it’s actually quite straightforward. By following the steps outlined above, you can be confident in starting your mower, keeping it running smoothly, and getting your lawn looking its best. Remember, always refer to your owner’s manual for specific instructions and safety precautions for your particular model. Happy mowing!
