How do I prepare my Petrol Chainsaw for Winter

Quick Answer

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

⚠️ Safety Notice

Before carrying out any maintenance:

• Switch off the chainsaw and allow the engine to cool completely.
• Work in a well-ventilated area away from open flames, sparks, or other ignition sources.
• Wear suitable protective gloves when handling the chainsaw.

Why Prepare Your Chainsaw for Winter?

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

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

Taking a few minutes to prepare your chainsaw before storage can help keep it in good working condition.

Preparing Your Chainsaw for Winter Storage

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 chainsaw and allow it to run until it stops naturally.

This removes any fuel remaining inside the carburettor.

Step 3: Clear the Fuel System

Press the primer bulb several times to move any remaining fuel through the fuel lines.

Attempt to restart the chainsaw.

If the engine does not start, the fuel system has been successfully emptied.

Storing Your Chainsaw

Store the chainsaw in a:

• Clean, dry location
• Well-ventilated area
• Place protected from moisture and extreme temperatures

Avoid storing the chainsaw in damp environments, as this can cause corrosion and damage to metal components.

If fitted, always engage the chain brake and fit the guide bar cover before storing the chainsaw.

Before Using the Chainsaw Again

When you're ready to use the chainsaw after storage:

1. Inspect the machine for any signs of damage or wear.
2. Fill the fuel tank with the correct fresh fuel mixture.
3. Check the chain oil reservoir and refill if required.
4. Inspect the guide bar and chain, adjusting the chain tension if necessary.
5. Start the chainsaw following the instructions in the user manual.

Where should I store my chainsaw?

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

Should I check the chain before using the chainsaw again?

Yes. Before using the chainsaw after storage, check the chain tension, guide bar, and chain oil level to ensure the machine is safe to operate.
