The Husqvarna 545 Mark II Gas Chainsaw features best-in-class cutting capacity that's ready for small and midsize tree trimming, felling and bucking. Smart Start offers an effortless start-up with a side-mounted tensioning system for simple slack adjustments. This gas powered chainsaw is equipped with Air Injection, a centrifugal air cleaning system, that removes dust and debris before it reaches the air filter, to improve engine life and reduce air filter cleanings. Additionally, AutoTune optimizes engine performance throughout various working conditions, compensating for things like different fuels, altitude, humidity, temperature and clogged air filters. For easy handling, this gas chainsaw is designed with a low, slender saw body and an anti-vibration system. The powerful, efficient 3.6 HP X-Torq engine reduces emissions (up to 60%) and increases fuel efficiency (up to 20%). It uses Husqvarna 2-stroke lubricant with a 50:1 oil tank volume (0.68 US pint or 0.32L tank volume).

For additional information on this product, please see the Product Documents section for all downloadable user manuals, installation guides, brochures and warranty statements.
