Quick Answer

If your petrol hedge trimmer is difficult to start, runs unevenly, or will not start at all, checking the spark plug is a good place to begin. A dirty, damaged, or faulty spark plug can prevent the engine from igniting the fuel mixture correctly, resulting in poor performance or failure to start.

⚠️ Safety Notice

Before carrying out any maintenance:

• Switch off the hedge trimmer and allow the engine to cool completely.
• Remove the spark plug cap to prevent accidental starting.
• Work in a well-ventilated area away from open flames or sources of ignition.
• Wear suitable protective gloves and eye protection.

Tools Required

You will need:

• Spark plug spanner or wrench

• Wire brush (recommended)
• Clean cloth
• Petrol (for cleaning, if required)

Step 1: Remove the Spark Plug

1. Remove the spark plug cap (high-tension lead) from the spark plug.
2. Using a spark plug spanner, turn the spark plug anti-clockwise until it can be removed.

Note: The spark plug may be tight and require some force to loosen.

Step 2: Inspect the Spark Plug

Examine the spark plug for:

• Carbon build-up
• Dirt or oil deposits
• Worn or damaged electrodes
• Cracks in the ceramic insulator

A dirty or damaged spark plug may not produce a strong enough spark for the engine to start or run correctly.

Cleaning the Spark Plug

If the spark plug is dirty:

• Clean the electrode and threads using a wire brush.
• Alternatively, wipe the spark plug with a clean cloth lightly dampened with petrol.
• Allow the spark plug to dry completely before testing or reinstalling.

If the spark plug is excessively worn or damaged, replace it with a new one of the correct specification.

Step 3: Test for a Spark

1. Reconnect the spark plug to the spark plug cap.
2. Hold the threaded section of the spark plug firmly against a clean, unpainted metal part of the hedge trimmer to create an earth connection.
3. Ensure the Start/Stop switch is in the START position.
4. Move to a shaded area where the spark is easier to see.
5. Pull the starter cord while observing the tip of the spark plug.

Results

• A white or blue spark indicates the spark plug is working correctly.
• No visible spark may indicate a faulty spark plug or an ignition system fault.

Important: Hold the spark plug using insulated pliers or another insulated tool. Keep your hands away from the electrode during testing to avoid electric shock.

Step 4: Test with a Different Spark Plug

If you have access to a known working spark plug:

1. Connect it to your hedge trimmer's spark plug cap.
2. Repeat the spark test.

Results

• If the replacement spark plug produces a spark, your original spark plug should be replaced.
• If neither spark plug produces a spark, the fault may be with the ignition coil or another part of the ignition system.

Step 5: Reinstall the Spark Plug

1. Carefully screw the spark plug into the engine by hand to avoid cross-threading.
2. Tighten it securely using the spark plug spanner.
3. Push the spark plug cap firmly back into place.

If the Problem Persists

If your hedge trimmer still does not start or continues to run poorly after checking the spark plug:

• Check the fuel mixture is fresh and correctly mixed.
• Inspect the air filter and clean or replace it if necessary.
• Ensure the fuel filter is not blocked.
• If there is still no spark, the ignition coil or another ignition component may require inspection or replacement.

If you require further assistance, please contact our Technical Support Team.

Quick Answer

If the fuel lines on your petrol hedge trimmer have become cracked, damaged, or detached, they should be replaced to restore a reliable fuel supply to the engine. When fitting new fuel lines, ensure they are routed correctly and connected securely to prevent fuel leaks and starting problems.

⚠️ Safety Notice

Before carrying out any maintenance:

• Switch off the hedge trimmer and allow the engine to cool completely.
• Remove the spark plug cap to prevent accidental starting.
• Empty the fuel tank before removing the fuel lines.
• Work in a well-ventilated area away from open flames, sparks, or other ignition sources.
• Wear suitable protective gloves and eye protection.

Before You Begin

You will require:

• Outlet hose (longer fuel hose)
• Inlet hose (shorter fuel hose)
• Replacement fuel filter (recommended if the existing filter is worn)

Tip: Place the replacement fuel hoses in hot (not boiling) water for a few minutes before installation. This softens the hoses, making them easier to feed through the fuel tank openings.

Understanding the Fuel Line Layout

Your hedge trimmer uses two fuel lines:

Correct routing is essential for the fuel system to operate properly.

Replacing the Outlet Hose (Longer Hose)

1. Feed the longer hose through the opening in the fuel tank.
2. Pull enough hose through the opening to attach the fuel filter.
3. Secure the fuel filter to the end of the hose inside the tank.
4. Position the filter so it can move freely and reach the fuel as the hedge trimmer is operated.
5. Connect the external end of the hose to the carburettor fuel inlet.

Replacing the Inlet Hose (Shorter Hose)

1. Feed the shorter hose into position.
2. Connect one end to the primer bulb.
3. Connect the opposite end to the correct carburettor connection.

This hose allows fuel to circulate through the fuel system each time the primer bulb is pressed.

Final Checks

Before starting the hedge trimmer:

• Ensure all fuel line connections are fully seated.
• Check that the fuel filter is securely attached inside the fuel tank.
• Inspect both fuel lines for kinks, twists, or trapped sections.
• Press the primer bulb several times and confirm that fuel flows through the system.
• Check carefully for any signs of fuel leakage.

If the Problem Persists

If the hedge trimmer still does not start or runs poorly after replacing the fuel lines:

• Check the fuel lines are connected to the correct carburettor ports.
• Ensure the fuel filter is not blocked.
• Verify the primer bulb is operating correctly.
• Confirm fresh fuel mixed to the manufacturer's recommended ratio is being used.

If you are unable to resolve the issue, please contact our Technical Support Team for further assistance.

Frequently Asked Questions

Why do fuel lines need replacing?

Fuel lines can harden, crack, or split over time due to age, vibration, and exposure to fuel, resulting in leaks or poor engine performance.

Which fuel line is longer?

The outlet hose is the longer hose. It carries fuel from the tank, through the fuel filter, to the carburettor.

Why should I place the fuel hoses in hot water?

Warm water softens the fuel hoses, making them more flexible and easier to install through the fuel tank openings.

Why isn't the primer bulb filling with fuel?

This usually indicates that the fuel lines are connected incorrectly, the fuel filter is blocked, or there is an air leak in the fuel system.

Can I reuse the old fuel filter?

If the fuel filter is dirty, damaged, or showing signs of wear, it should be replaced when fitting new fuel lines to ensure reliable fuel flow.
