FAQ
Should I choose a petrol or battery chainsaw?
Both petrol and battery chainsaws can provide excellent cutting performance, so the best choice depends on how you plan to use the saw. Battery chainsaws are quiet, easy to start, low maintenance and well suited to pruning, property maintenance and regular firewood cutting. Petrol chainsaws offer long continuous running time and remain a strong choice for demanding work, larger timber and situations where you need to work for extended periods away from battery charging.
What size chainsaw do I need?
Choose a chainsaw according to the type and diameter of timber you expect to cut most often rather than simply buying the largest saw available. Smaller chainsaws are lighter and easier to manoeuvre for pruning, garden maintenance and smaller firewood. Larger and more powerful saws are better suited to heavier timber, frequent cutting and more demanding rural or professional work.
What chainsaw bar length should I choose?
Guide bar length should suit the size of timber being cut and the power of the chainsaw. A shorter bar is generally lighter and easier to control, making it a good choice for pruning, smaller logs and general property maintenance. Longer bars allow larger diameter timber to be cut but add weight and require a saw designed to drive that cutting equipment. Always stay within the bar lengths approved for the particular chainsaw model.
What type of chainsaw is best for cutting firewood?
For occasional firewood cutting, a lightweight or mid-sized chainsaw may be all that is required. If you regularly process larger quantities of hardwood or larger diameter logs, a more powerful saw with an appropriately sized guide bar will generally make the work faster and place less strain on the machine. Battery chainsaws can be excellent for regular domestic firewood use, while petrol models remain popular for prolonged or particularly demanding cutting.
What chainsaw do I need for hardwood or larger trees?
Dense hardwood and larger timber require more cutting power than small branches or softwood. Choosing an undersized chainsaw for consistently heavy work can slow cutting and place unnecessary load on the machine. If you regularly work with large Australian hardwood logs or substantial trees, look for a model specifically designed for heavier-duty use with an appropriate power output and manufacturer-approved guide bar.
Is a lighter chainsaw better for home use?
Often, yes. A lighter chainsaw can be easier to manoeuvre and less tiring during pruning, firewood preparation and general property maintenance. Weight and balance are important because fatigue can make a chainsaw harder to control. The ideal saw provides enough power for your normal cutting jobs without being unnecessarily large or heavy for the person using it.
How long will a battery chainsaw run?
Battery chainsaw runtime depends on battery capacity, the saw, timber size and hardness, and how continuously you are cutting. Light pruning can require far less energy than repeatedly cutting large hardwood logs. For larger properties or longer working sessions, consider a higher-capacity battery or an additional battery. Choosing a battery system shared with your other garden equipment can also make batteries and chargers more useful across several tools.
Can I fit a longer guide bar to my chainsaw?
Many chainsaws can use more than one guide bar length, but that does not mean any bar can be fitted to any saw. The engine or motor, chain specification, sprocket and lubrication system are designed to work within a particular range of cutting equipment. Use only bar and chain combinations approved for your chainsaw model, as an excessively long or incompatible setup can reduce performance and affect safe operation.
What safety equipment should I have when using a chainsaw?
Chainsaw work requires appropriate personal protective equipment. Depending on the job, this commonly includes chainsaw protective legwear, suitable boots, eye and hearing protection, gloves and head protection. The equipment should suit both the saw and the type of work being undertaken. If you are new to chainsaws, professional instruction or practical guidance is also worth considering before tackling more demanding cutting or tree work.
What maintenance does a chainsaw need?
Regular chainsaw maintenance includes keeping the chain correctly tensioned and sharp, maintaining adequate chain lubrication, cleaning the guide bar and checking the chain, sprocket and other cutting components for wear. Petrol models also require engine-related servicing such as air-filter and fuel-system maintenance, while battery models generally require less routine servicing. Following the manufacturer's maintenance schedule and using compatible replacement bars, chains and parts helps maintain reliable cutting performance.
