Husqvarna 445S

Husqvarna 445S is a chainsaw designed to handle all your tasks, from forestry work like felling, cutting, and limbing to cutting firewood. Building on the reliable 400 series, this light chainsaw offers improved ease of use and a reinforced, robust design, as well as an optimized 2,2 kW X-Torq® engine for increased performance. The upgraded cutting experience is also ensured by the easy start function and features such as colored felling marks and captured bar nuts.

The 445S is engineered for residential users who need a versatile, powerful, and easy-to-use chainsaw for firewood cutting, pruning, and storm cleanup.

The 445S delivers 20% faster cutting than the previous 445 model, thanks to an optimized X-TORQ® engine and improved design.

The 445S features a 50.2 cc engine with 3 horsepower.

It comes standard with an 18" bar (recommended range: 13"–20") and uses the SP33G X-Cut chain.

The 445S includes Smart Start® technology, a quick-release air filter, captured bar nuts, visible felling marks, and a flip-up fuel cap.

It features LowVib® anti-vibration, inertia-activated chain brake, and side-mounted chain tensioning.

The 445S comes with a 2-year limited warranty for residential, non-income producing use. You can extend your warranty up to 5 years by purchasing at least 96 fl. oz. of Husqvarna pre-mixed fuel & oil at the same time as your chainsaw and registering your product online.

The warranty does not cover normal wear parts (such as air filters, spark plugs, chains, etc.), damage from improper maintenance, misuse, use of non-approved fuels (E15/E85), or commercial/rental use.

Using the chainsaw for commercial, agricultural, or rental purposes, failing to perform required maintenance, or using non-approved fuels will void the warranty.

Take your product and proof of purchase to an authorized Husqvarna servicing dealer. You are responsible for transportation costs. Registration is recommended but not required for service.

Keep your proof of purchase (receipt) for the entire warranty period, as Husqvarna may require it for verification before performing warranty work.
