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).

Husqvarna 440E is a popular mid-level chainsaw.

The Husky 440 E chainsaw is a 18” (45 cm) lightweight, powerful and efficient all-round gas chainsaw. It’s an ideal chainsaw for general use on farms and estates when cutting small wood and firewood. The Husqvarna 440 E is a high-quality efficient chainsaw that delivers impressive performance and is easy to look after. A 40.9 cc engine with X-Torq technology.

Weighing in at 9.7 pounds (4.39 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 15.2 x 8.6 x 11.1” (L x W x H) make it the smallest semi-professional Husqvarna saw.


The Husqvarna 440e saw has a forged three-piece crankshaft that gives it maximum durability and allows it to cope with the toughest tasks.

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

Combined choke/stop control makes the common problem of flooding much less likely to happen.


Like most Husqvarna chainsaws, it uses a 2-stroke (or 2-cycle) air cooled engine. The 440e specifically has a 40.9 cc engine, that can produce up to 2.4 horsepower, which is plenty enough for any medium duty work. It can cut through most trees with little trouble.

The engine uses the efficient X-Torq technology which cuts fuel consumption up to 20% and decreases emissions. This saves you money on fuel and you’ll breathe less 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. The 440 E chainsaw fuel tank is not that big, you should still get about 2 hours of use.

Difference between Husqvarna 440 and 440E?
They’re nearly identical, though the newer 440E has a tool-less chain tensioning system. Both have the same engine and are made to withstand light and medium workload.
