Husqvarna 543 XP Review

Husqvarna 543 XP is a light and effective saw developed for tree care professionals and skilled landowners. The combination of low weight and high chain speed leads to efficient limbing work. Our unique X-Torq engine technology provides more power where you need it, including up to 20% less fuel consumption and 75% less exhaust emission.

Pros & Cons

  • Lightweight
  • Great for limbing
  • High chain speed
  • Price
  • No snap-lock cylinder cover


Great all-around saw. It’s not the most powerful you can find, but it can still handle most of the medium use. The chain speed is very fast. Depending on when you’re reading this, the saw might be discontinued.


Slimmed-down design

The chainsaw is easy and convenient to handle in any situation thanks to its low and slender body.

Felling marks

Distinct, colored marks on the chainsaw body used for aiming the direction of tree fall.

Retained bar nuts

This function prevents losing the bar nuts.

Side-mounted chain tensioner

Easier access to chain tensioning device compared to the front tensioning.

Snap-lock cylinder cover

When you need to change anything inside the saw or do some cleaning, you just pop the snap-lock on each side of the saw and you’re good to go.

Air Purge

When pressed, it removes air from the carburetor and fuel system for easy starting.

Adjustable oil pump

You can control oil flow based on application and weather conditions.

Visible fuel level

The fuel tank is transparent, so you can see how much fuel is left.


Three-piece crankshaft

Forged three-piece crankshaft for maximum durability for the toughest applications.

Air Injection

The centrifugal air cleaning system prevents larger dust and debris particles from reaching the air filter. In return you get improved engine life and less maintenance cleaning the air filter. All Husqvarnas have this.

Magnesium crankcase

Sturdily built crankcase withstands high RPMs and tough professional use. This ensures a long service life.



The vibration dampening system called LowVib is present in all Husky chainsaws. Metal springs in the engine suspension reduce vibrations felt by the operator. This allows you to work longer without your hands getting exhausted and it also prevents developing medical conditions.

The front handle and hand guard are offset by 7° to provide more natural holding position.

Inertia activated chain brake

In case of kickback the inertia mechanism will stop the chain from running. This significantly reduces the risk of injury.


There are several things that make starting the saw easy, such as the auto return stop switch or the Smart Start, which reduces the amount of cord pulls you have to make before the saw starts running.


Probably the best thing about newer Husqvarna saws. It reduces emissions by up to 60% and fuel consumption by up to 30%. You spend less on gas and breathe less fumes. It also makes the saw CARB compliant.
