How do I prepare my Petrol Hedge Trimmer for Winter

Quick Answer

Preparing your petrol hedge trimmer for winter storage helps prevent fuel deterioration, carburettor blockages, and starting problems. Before storing the machine, empty the fuel tank, run the engine until it stops, clear any remaining fuel from the system, and store the hedge trimmer in a clean, dry location.

Note: The accompanying video demonstrates this procedure using a CDB30 grass trimmer. However, the same principles apply to most 2-stroke petrol-powered garden machines, including petrol hedge trimmers.

⚠️ Safety Notice

Before carrying out any maintenance:

• Switch off the hedge trimmer and allow the engine to cool completely.
• Work in a well-ventilated area away from open flames, sparks, or other sources of ignition.
• Wear suitable protective gloves when handling the cutting blades.
• Ensure the blade cover is fitted before storing the machine.

Why Prepare Your Hedge Trimmer for Winter?

Fuel left in the machine during long periods of storage can deteriorate and leave deposits in the fuel system. This can lead to:

• Starting difficulties
• Poor engine performance
• Blocked carburettors
• Additional maintenance before the next season

Preparing your hedge trimmer correctly before storage will help keep it in good working condition and make it easier to start when required again.

Winter Storage Procedure

Step 1: Empty the Fuel Tank

Drain any remaining fuel from the fuel tank into a suitable container.

Removing old fuel helps prevent residue and varnish from forming inside the fuel system during storage.

Step 2: Empty the Carburettor

Start the hedge trimmer and allow it to run until it stops naturally.

This uses the remaining fuel in the carburettor and fuel lines.

Step 3: Clear the Fuel System

Press the primer bulb several times to circulate any remaining fuel through the fuel system.

Attempt to restart the engine.

If the engine does not start, the fuel system has been successfully emptied and the hedge trimmer is ready for storage.

Step 4: Store the Hedge Trimmer

Store the machine in a:

• Clean, dry location
• Well-ventilated area
• Place protected from moisture and direct sunlight

Where possible:

• Store the hedge trimmer off the ground.
• Keep it in a shed, garage, or other dry environment.
• Protect it from excessive dust and damp conditions.
• Fit the blade cover before storage.

Additional Maintenance Before Storage

For the best protection during storage, we also recommend:

• Cleaning the cutting blades thoroughly.
• Applying a suitable blade lubricant or protective oil.
• Inspecting the machine for signs of wear, damage, or loose fixings.
• Cleaning or replacing the air filter if required.
• Wiping down the exterior to remove dirt, sap, and moisture.

Before Using the Hedge Trimmer Again

Before using the machine after winter storage:

1. Fill the fuel tank with fresh fuel mixed to the manufacturer's recommended ratio.
2. Inspect the fuel lines and primer bulb for signs of cracking or deterioration.
3. Check the cutting blades for damage and lubricate them if necessary.
4. Ensure all controls operate correctly.
5. Start the hedge trimmer following the normal starting procedure.

Frequently Asked Questions

Why should I drain the fuel before winter?

Fuel can deteriorate during storage, leaving deposits that may block the carburettor and make the engine difficult to start.

Should I leave fuel in the carburettor?

No. Running the engine until it stops helps remove fuel from the carburettor and reduces the risk of fuel-related problems during storage.

Where should I store my hedge trimmer?

Store it in a clean, dry, and well-ventilated location away from moisture, direct sunlight, and sources of ignition.

Should I lubricate the blades before storage?

Yes. Applying a suitable blade lubricant or protective oil helps prevent corrosion and keeps the blades in good condition.

What should I check before using the hedge trimmer again?

Inspect the fuel system, refill with fresh fuel, lubricate the blades, and ensure all controls and safety features are operating correctly before use.
