Husqvarna 439 Review

Husqvarna 439 is a compact and very light, medium-range 14” (35 cm) chainsaw. It’s a handy tool for farmers and demanding consumers who need a versatile tool for lighter cutting tasks. If you’re looking for the lightest possible saw in this range you’re in the right place.


For some reason, the Husqvarna 439 is not talked about at all online even though it’s not bad at all. For people who want a very light saw, this might be the one. But to get to such a lightweight, the performance was sacrificed. It’s also a bit pricey. If you don’t care about carrying around about 2 more pounds (1.2 kg) in your hands, you can get something like the Husqvarna 450, which offers A LOT more power for the same price.


Husqvarna’s been making chainsaws for a long time now, so they probably know a thing or two about designing their products to be a pleasure to use. They’ve optimized the saw body so there are no protruding parts, the underside is smooth, the starter cover is rounded and the controls are well-protected. They’ve also offset the front handle by 7° so you get a better grip and it’s more natural to hold.

Weighing in at 8.64 pounds (3.91 kg) it’s the lightest one in this range. You can easily position it to prune one limb while leaving the one next to it untouched.

The dimensions of 17.32 x 9.44 x 10” (L x W x H) make it the smallest semi-professional Husqvarna saw. Storing or transporting in the trunk of a car is no problem.

The saw comes with a 14” (35 cm) low kickback bar, but you can use one from 12” (30 cm) up to 16” (40 cm). As far as chains go, some people prefer Oregon chains, so you can try it as well when yours gets blunt. You can sharpen the chain yourself or take it to your local dealer to do it for you. Depending on how busy your dealer is, he may not do it immediately, so it’s better to have a backup chain.


The Air Injection centrifugal air cleaning system reduces wear and increases operating times between filter cleanings.

Ease of use

The air filter is quick and easy to release.

With an adjustable oil pump, you can control oil flow depending on application and weather conditions.

Equipped with Smart Start, fuel pump, and auto return stop switch for easier starting. You’ll need less cord pulls to get started.

The air purge bulb and fuel pump do a good job of making starting easier.

A transparent window in the fuel tank makes refueling straightforward.

You can use felling marks to help you align the saw to a tree more accurately.


Probably the most important feature is Husqvarna’s inertia-activated chain brake system that takes a lot of the fear out of kickbacks. You’re cutting through a fallen tree and suddenly, you hit a knot and the bar jumps back at you. This situation was once every chainsaw operator’s greatest dread. It’s still scary, but it’s also when the sudden change in inertia activates this saw’s chain brake. This prevents potentially fatal consequences.

A vibration dampening system called LowVib cuts down on user fatigue. In turn, your enjoyment is increased and the odds of getting hurt are reduced.

I recommend getting additional safety gear if you don’t have one yet.


Like most Husqvarna chainsaws, it uses a 2-stroke (or 2-cycle) air-cooled engine. This model specifically has a 35.2 cc engine, that can produce up to 2.01 horsepower, which is enough for any medium-duty work. It can cut through most trees without getting bogged down.

The engine uses efficient X-Torq technology which cuts fuel consumption up to 20% and decreases emissions. This saves you money on fuel and you’ll breathe fewer fumes. It’s also CARB compliant.

It uses a gas and oil mix for fuel. The ratio is the usual 50:1 (gas to oil). It’s important to use good quality unleaded gas with at least an 87 octane rating. In fact, it’s recommended to use 89 or better, just to be safe.

Since it produces so little vibrations, you’ll be able to make accurate and clean cuts, even after using it for a while. You can further increase your quality of life by getting a pair of anti-vibration gloves.

If you decide to get one for yourself, make sure not to run it at high speeds for the first 10 hours or so. You’ll be glad you did because it’ll increase the engine life noticeably.

As far as noise goes, all gas chainsaws are noisy and this is no exception. At 112 dB(A) it’s no noisier than other Husqvarna chainsaws in this range. To protect your hearing, I recommend a helmet or at least earplugs.


You get 90 days of commercial warranty and standard 2 years of homeowner warranty. You can buy an increased 2 or 3-year protection plan on Amazon.
