Petrol chainsaws are a powerful tool for tackling demanding forestry and agricultural tasks, or large garden maintenance projects. These machines deliver significant cutting power compared to electric alternatives, driven by the combustion of petrol – crucial for robust performance in challenging conditions. They’re generally heavier and require more user skill than cordless options.
When choosing a petrol chainsaw, engine size (measured in cc) is a key factor, influencing both power and noise levels. Larger engines provide greater torque for tackling thicker branches and larger logs. Consider the bar length too; longer bars increase cutting capacity but can impact maneuverability. Always prioritise safety features like chain brakes and throttle guards.
Remember that petrol chainsaws demand regular maintenance – including oil changes and air filter cleaning – to maintain optimal performance and longevity. Due to their power, they require a cautious approach and adherence to all manufacturer’s instructions. Amazon offers a range of models with varying engine sizes and features; carefully compare specifications before purchasing.

FAQ
What type of fuel does a petrol chainsaw need?+
Petrol chainsaws typically operate on unleaded petrol, though some models may benefit from using fuel mixed with an anti-stain additive. Always check the manufacturer’s instructions for specific recommendations.
How often should I change the oil in my petrol chainsaw?+
Oil changes are essential for maintaining engine lubrication and preventing wear. The frequency depends on usage, but generally every 25-50 hours of operation is recommended – or more frequently if used heavily.
What kind of chain brake does a petrol chainsaw have?+
Most petrol chainsaws feature an inertia chain brake, which automatically engages when the trigger is released and the engine is under load. This significantly reduces the risk of injury from kickback.
How do I sharpen my chainsaw chain?+
You’ll need a chain sharpening kit – typically including a guide and file. Carefully follow instructions for each step, ensuring you maintain the correct angle to avoid damaging the chain.
What safety gear should I wear when using a petrol chainsaw?+
Always wear appropriate personal protective equipment (PPE), including eye protection (safety glasses or goggles), hearing protection, gloves and long trousers. Sturdy boots are also crucial.
Are petrol chainsaws difficult to start?+
Older models can be tricky to start; however, modern chainsaws often have electric starting systems. Ensure the fuel level is adequate and follow the manufacturer’s starting procedure carefully.
How much does a new chainsaw chain cost?+
Replacement chains vary in price depending on length and quality, typically ranging from £15 to £50. It's best to buy replacement chains specifically designed for your chainsaw model.
What is the noise level of a petrol chainsaw?+
Petrol chainsaws are inherently noisy due to the engine’s operation. Noise levels vary by model but can reach around 90-110 dB(A) – always wear appropriate hearing protection.
How do I maintain the air filter on my chainsaw?+
Regularly check and clean the air filter, usually every 25 hours of use. A dirty filter restricts airflow and reduces engine performance. Replacement filters are readily available.
Can I store a petrol chainsaw outdoors?+
While some models are designed for outdoor storage, it’s best to avoid prolonged exposure to the elements. Protect the engine from rain and direct sunlight to prevent corrosion and prolong its lifespan.
