Husqvarna’s 545 petrol chainsaw, supplied with a 15″ bar and chain, utilizes the innovative X-Torq technology, delivering enhanced power where it matters most while improving overall efficiency.
Featuring effective anti-vibration dampeners through Husqvarna’s LowVib system, this chainsaw minimizes vibrations, providing comfort for your arms and hands. Its streamlined design makes it easy to handle in various situations. The side-mounted chain tensioner ensures convenient access, and retained bar nuts prevent accidental loss. A visible fuel level prevents unexpected interruptions, and felling marks contribute to improved precision.
Designed for full-time professional use on small to medium diameter timber, the 545 boasts a magnesium crankcase capable of withstanding high rpms and heavy-duty usage for an extended service life. The forged three-piece crankshaft enhances durability for challenging applications, while the centrifugal air cleaning system reduces wear and extends time between filter cleanings.
Equipped with a 50.1cc engine featuring X-Torq, this model achieves lower fuel consumption, reduced emissions, and increased torque where it’s most needed. Husqvarna’s AutoTune system ensures optimal engine performance by automatically adjusting for fuel, altitude, humidity, temperature, and air filter condition. The Smart Start feature reduces resistance in the starter cord by up to 40 percent, making the machine effortlessly easy to start.
For added safety, an inertia chain brake is included to halt the saw in the event of a sudden upward movement. The Husqvarna 545 combines top-quality design, high-performance operation, and user-friendly features, making it an excellent choice for professional use.
This petrol chainsaw requires a mixture of petrol and 2-stroke oil at 50:1.
The quality of the petrol and oil is extremely important with running and the life of the engine.
Unsuitable fuels or mix ratios that do not comply with the specification can cause damage the engine (piston seizing, excessive wear)
We recommend to run your chainsaw on E5 petrol if possible, and always ensure the fuel is used or disposed of after 30 days have passed.
