Chainsaws are used in many environmental conditions to cut down trees, break up debris and sometimes even to shape topiary or ice sculptures. The Husqvarna 345 chainsaw is designed to perform in all of these conditions and has several specifications that help the Husqvarna 345 cut longer and meet a range of challenges.



The power of a chainsaw engine determines many things, such as the size of the chain bar, the speed at which the chain rotates the vibration of the unit and the type of work the saw can perform. The Husqvarna 345 features a 45 CC 2-cycle engine that runs at 3.0 horsepower, which provides an idle speed of 2,700 rpm and a speed of 9,000 rpm at full power. The engine also features Champion RCJ7Y spark plugs and an SEM Capacitor Discharge (CD) NGK BPMR 7 Amp ignition system. Husqvarna Smart Start technology gives the 345 model chainsaw a quick reaction time.


The Husqvarna 345 chainsaw weighs 10.4 lbs. This lightweight design gives the user more freedom when manipulating the saw around wood or debris.

Fuel System

The fuel tank on a Husqvarna 345 chainsaw can handle up to 0.5 liters of fuel mixture. The inner workings are lubricated with an automatic oil pump pumping 0.25 liters of 2-stroke oil which operates at up to 9 ml per minute at top speed. All of this is regulated and cooled by a Zama C3-EL18 carburetor. The type of fuel used in the Husqvarna 345 is a mixture of 2 percent 2-stroke oil and 98 percent gasoline. Low 87 octane gasoline or regular unleaded gasoline is recommended for use. A lower octane gasoline than 87 can cause engine knocking, while a higher octane can overheat the engine, causing serious damage and possible injury.


The standard length of bar that comes with the Husqvarna 345 is 13 inches but can be increased up to 20 inches with a 19-inch usable cutting length.


Although chainsaws are sold on their cutting power, good chainsaws also include features to help keep the user safe. The Husqvarna 345 includes several safety features, such as low vibration technology, dual action chain brake for faster stopping and an air injection system. Additionally, the Husqvarna 345 includes a side-mounted chain tensioner.
