Carburetor – General Chainsaw Adjustment
Adjusting the carburettor involves adjusting the engine to the local conditions e.g. climate, altitude, fuel and type of two-stroke oil. The carburettor is equipped with three adjustment options.
L = Low speed jet
H = High speed jet
T = Idling adjustment screw
The L and H jets adjust the fuel flow to match the airflow that the throttle valve opening allows. Turning them clockwise makes the fuel/air mixture weaker (less fuel in relation to the amount of air) and turning them anti-clockwise makes the fuel/air mixture richer. A weak mixture increases the engine speed and a rich mixture decreases the engine speed. The T screw controls the throttle position when idling. Turning the T screw clockwise gives faster idling; turning it anti-clockwise lowers idling speed (see manual for complete guide).

Sturdily built crankcase withstands high RPMs and tough professional use. This ensures a long service life.
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.
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.
Forged three-piece crankshaft for maximum durability for the toughest applications.
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.
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 combined start/stop switch and fuel pump or the Smart Start, which reduces the amount of cord pulls you have to make before the saw starts running.
