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).

The Husky 455 E-Series Triobrake Chainsaw has a 3.5 hp 55.5 cc motor that puts out 9,000 rpm to cut through the hardest of woods. You do not need to give it throttle to start it and it has a compression switch for easier starts. The controls are simple to use, just pull the choke which is combined with the stop switch for easier starting.
TrioBrake on Husqvarna chainsaws means the chain can be stopped by inertia via the front hand shield or the brake activator at the rear (a right-handed trigger).
The 455 E Triobrake boasts easy handling and high torque over a wide rpm range, offering impressive performance in all cutting conditions. Usually supplied with a 18 to 24 inch inch bar length.
