How to Start a Petrol Lawn Mower

Starting a petrol lawn mower for the first time—or after a long period of inactivity—can sometimes be a bit tricky. Understanding the correct procedure is essential to ensure your mower runs smoothly and efficiently. In this guide, we will walk you through the steps to start your petrol lawn mower, ensuring a hassle-free experience. Should you encounter difficulties, remember that MowShop has six service depots across the UK to provide professional assistance.

1. Prepare the Mower

Before attempting to start your petrol lawn mower, it’s important to prepare both yourself and the mower.

1. Check the Fuel: Ensure the petrol tank is filled with fresh fuel. Stale petrol can cause starting problems, so it’s advisable to use petrol that’s no older than a month. If you’re using fuel from a previous season, consider replacing it with fresh petrol.
2. Inspect the Oil Level: Verify that the engine oil is at the correct level. Consult your mower’s manual for the recommended type of oil and the proper level. Adding oil if it’s low is crucial for engine health.
3. Inspect the Air Filter: A clean air filter is essential for efficient engine operation. Check the air filter and clean or replace it if necessary.
4. Check the Spark Plug: Ensure the spark plug is in good condition and properly connected. A faulty spark plug can prevent the mower from starting. Replace it if it appears worn or dirty.

2. Starting Procedure

With your mower prepared, follow these steps to start it:

1. Engage the Choke: If your mower has a choke, engage it by pulling it to the ‘on’ position. The choke helps to enrich the fuel mixture for a smoother start, especially in colder weather.
2. Set the Throttle: Set the throttle to the ‘fast’ position. This setting provides the necessary engine speed for starting.
3. Prime the Engine: Some mowers have a primer bulb that needs to be pressed several times to pump fuel into the carburettor. Refer to your mower’s manual for the exact number of presses required.
4. Ensure the Safety Features are Activated: Most modern petrol mowers come with safety features like blade brakes and handles that need to be engaged before starting. Make sure these are correctly positioned.
5. Pull the Starter Cord: Firmly grasp the starter cord handle and pull it sharply. You may need to pull the cord a few times before the engine starts. Be sure to pull the cord straight out and avoid yanking it too aggressively to prevent damage.
6. Disengage the Choke: Once the engine starts, gradually disengage the choke to allow the engine to warm up.
7. Check Engine Performance: Let the mower run for a few minutes before beginning to mow. This allows the engine to reach its optimal operating temperature and ensures smooth operation.

3. Troubleshooting Common Issues

If your mower does not start after following the steps above, consider these troubleshooting tips:

• Check for Fuel Blockages: Ensure there are no blockages in the fuel lines or filter.
• Inspect the Battery (for electric start models): If your mower has an electric start, check the battery’s charge.
• Examine the Starter Mechanism: Ensure the starter mechanism is functioning correctly and that there are no obstructions.
