⚠️ Safety Notice

Ensure the chainsaw is switched off before carrying out any inspection or maintenance.

Do not smoke or work near naked flames when handling fuel.

Fuel Age and Fuel Mix Check

Incorrect or old fuel is one of the most common causes of engine performance issues.

Check the Fuel Age

• Ensure you are using fresh unleaded petrol that is less than 30 days old.
• Fuel that has been stored for longer periods can deteriorate and affect engine performance.
• If the fuel is older than 30 days, drain the fuel tank safely and replace it with a fresh fuel mixture.

Check the Fuel-to-Oil Ratio

• Ensure you are using the correct fuel mixture of 40:1.
• This equates to:
  • 1000ml (1 litre) of unleaded petrol
  • 25ml of 2-stroke engine oil

Using an incorrect fuel mixture may cause starting problems, poor performance, or engine damage.

1. Pull the starter cord to start the engine.
2. Disengage the chain brake
3. Ready to use
