The second generation of Husqvarna’s 545 chainsaw is a 50cc unit that’s ready for felling, limbing and bucking of small and midsize trees. Designed for professional forestry and tree care crews, this durable saw has improved power and a slimmed-down design. A host of innovative features guarantee comfortable and efficient operation, season after season.

Features

  • RETAINED BAR NUTS: The retaining function prevents loosing the bar nuts.
  • SLIMMED-DOWN DESIGN: Low, slender saw body makes the chainsaw easy and convenient to handle in any situation.
  • LOWVIB®: System designed to reduce vibration levels to the operator, which lessens fatigue.
  • ADJUSTABLE OIL PUMP: Allows you to control oil flow depending on application and weather conditions.
  • MAGNESIUM CRANKCASE: Sturdily built crankcase withstands high rpms and tough professional use, ensuring a long service life.
  • X-TORQ®: Delivers lower fuel consumption and reduced exhaust emission levels in accordance with the world´s most stringent environmental regulations.
  • AUTOTUNE: AutoTune gives optimal engine performance throughout automatic engine setting. No time spent on carburetor adjustments. It compensates for different fuels, altitude, humidity, temperature and clogged air filter.
  • EXCELLENT COOLING CAPACITY FOR A LONGER ENGINE LIFE: Our new cooling system is optimised in every detail to give you a reliable chainsaw for any situation.
  • FELLING SIGHT TO LAST A LIFETIME: Perfect sight is critical when felling – so we made one that will outlast the chainsaw itself.
  • AIR INJECTION®: Centrifugal air cleaning system removes larger dust and debris particles before reaching the air filter. This results in reduced air filter cleanings and improved engine life.
  • SNAP-LOCK CYLINDER COVER: Saves time when changing spark plugs and cleaning.
  • VISIBLE FUEL LEVEL: Transparent fuel indicator makes it easy to check fuel level.
  • SIDE-MOUNTED CHAIN TENSIONER: Easier access to chain tensioning device.
  • SMART START®: The engine and starter have been designed so the machine starts quickly with minimum effort.
  • THREE-PIECE CRANKSHAFT: Forged three-piece crankshaft for maximum durability for the toughest applications.
  • EASY TO START: Combined start/stop switch and fuel pump make the saw very easy to start.
  • RETAINED STARTER SCREWS: The retaining function prevents loosing the screws holding the starter.
