Cutting firewood with a chainsaw: working effectively and safely

Using a chainsaw to cut your own firewood is certainly more cost effective than buying logs, and can also be more sustainable. Here’s how to do it.

Protective equipment when cutting firewood

First things first, whenever you are working with a chainsaw you need to be wearing the appropriate Personal Protective Equipment.   This includes face protection and safety glasses to protect your face and eyes from flying wood chips. If you are using a petrol chainsaw, you will need ear protection, such as ear plugs or ear defenders, but if you are using a cordless chainsaw, most of them are so quiet that they do not require ear protection.  You should also protect your hands, legs and feet properly by wearing appropriate cut protective work gloves, chainsaw trousers and boots.  For those just getting started, we make a chainsaw PPE starter kit that includes the basics.

Before you use your chainsaw for the first time, read the operating manual for your machine to familiarise yourself with the tool, and make sure it is in good working condition before each use.  Please remember that personal protective equipment is no substitute for safe working techniques.

Which firewood?

If you don’t use your fireplace often, most wood will be suitable. Soft woods, such as spruce, will heat up faster, due to their higher resin content. This also means that they burn more quickly so you will need to add logs to the fire more often.

Hard woods, such as beech or oak, take longer to heat up but burn for much longer. This makes them well suited if you use your stove or fireplace for longer periods of time.

Make sure the wood is seasoned (dried out) before burning it. For the best burn and heat output, firewood should be seasoned until its moisture content is around 20%. You can easily check wood moisture content with the help of our wood moisture gauge.

Firewood with a higher moisture content is hard to light and keep burning, plus the heat that is produced is wasted in drying the excess moisture. More importantly, the tars and creosote in the smoke produced by the excess moisture can line flue pipes and your chimney and eventually cause a fire.  Plus lots of smoke is never a good thing for you or your neighbours.

Cutting to length

To get started turning a fallen tree into firewood, we recommend cutting all the timber into one metre lengths that are easier to work with. You can cut the wood directly on the ground if it’s flat enough, or you can quickly make yourself a cutting stand from other pieces of wood.  Just make sure you have permission before getting started as there are restrictions and regulations around processing wood from a fallen tree in the UK.

Tips for sawing firewood from a trunk on the ground

If the trunk is on a solid, even surface you can use your chainsaw to cut it up directly on the ground, but make sure your chainsaw does not cut into the ground, as this will blunt the chain.

The very first step before you use the chainsaw to make firewood is to check that the trunk cannot roll away, by securing the log with wedges or smaller pieces of wood.

If the surface of the ground is not suitable for working on directly, you may need some kind of stand to help you: this not only saves your saw chain but also your back.  You can quickly create an ideal log support by cutting a groove in a piece of wood.  Remember to always make sure that any wood you are cutting with a chainsaw is secured in place and not able to roll away before you start.

Splitting the lengths for firewood

Metre-long pieces of trunk probably won’t fit in your fireplace, and thicker trunks need to be split for ease of use – in any case, smaller pieces of firewood will always dry better and more quickly than large logs. This is important, as damp wood is hard to light, doesn't burn well and releases soot and smoke.

Processing into firewood

It’s best to use a sawhorse when processing split lengths of wood and smaller branches to create firewood. A sawhorse helps you secure the wood safely, and at a good height for conveniently cutting firewood.

Storing firewood

Once you have cut your own logs, they will need to dry for 1-2 years before they can be used on the fire (softwoods will season quicker than hardwoods, such as oak, which will likely need the full two years).  Make sure that you stack your logs so that the air can circulate between them. Then cover them with a waterproof tarpaulin to protect them from rain and damp weather.

Made for medium-power chainsaw, our Picco Duro 3 saw chain, uses carbide-tipped teeth that are no match even for dirty or particularly tough wood. Designed for durability, it stays sharp for up to four times longer than standard saw chains.

Summary: cutting firewood with a chainsaw

  • Depending on the subsurface and task, you can work directly on the ground, on a sawhorse, or on a cutting stand 

  • Personal protective equipment is required for cutting firewood with a chainsaw

  • Collecting wood in a forest requires the owner’s permission or a permit, and may be subject to restrictions
