MAINTENANCE

Carburetor

WARNING! The complete clutch cover and

!shaft must be fitted before the machine is started, otherwise the clutch can come loose and cause personal injury.

Function

•The carburetor governs the engine’s speed via the throttle control. Air and fuel are mixed in the carburetor.

•Setting the carburettor involves adapting the engine to suit local conditions, e.g. climate, altitude and the petrol.

Basic setting

The basic carburetor settings are adjusted during testing at the factory.

CAUTION! For optimum adjustment of the carburettor, contact a qualified dealer/service workshop that has a revolution counter at their disposal.

Adjusting the idle speed (T)

Check that the air filter is clean. When the idle speed is correct, the cutting attachment should not rotate. If adjustment is required, close (turn clockwise) the idle adjustment screw T, with the engine running, until the cutting attachment starts to rotate. Open (turn anticlockwise) the screw until the cutting attachment stops. The idle speed is correctly set when the engine runs smoothly in all positions, and there is a clear margin to the speed at which the cutting attachment starts to rotate.

WARNING! If the idle speed cannot be

!adjusted so that the cutting attachment stops, contact your dealer/service workshop. Do not use the machine until it has been correctly adjusted or repaired.

Muffler

CAUTION! Some mufflers are fitted with a catalytic converter. See chapter on Technical data to see whether your machine is fitted with a catalytic converter.

The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material.

The muffler on your machine is equipped with a spark arrestor screen, this should be cleaned regularly. A blocked screen will cause the engine to overheat and may lead to serious damage.

CAUTION! Never use a machine with a defective muffler.

WARNING! Mufflers fitted with catalytic

!converters get very hot during use and remain so for some time after stopping. This also applies at idle speed. Contact can result in burns to the skin. Remember the risk of fire!

One of the primary characteristics of these models is their cutting efficiency. Both the 324L and 324LD are equipped with a robust 25.4cc two-stroke engine that provides a strong power-to-weight ratio, allowing users to tackle various tasks with ease. The engines in these trimmers are designed for performance and deliver a consistent cutting speed, making them suitable for everything from refined garden edges to clearing dense brush.

The lightweight design further enhances maneuverability, allowing users to navigate around obstacles and reach difficult areas without straining.

Another notable feature is the excellent cutting system. Both models include a Tap ‘n Go spool, which allows users to easily extend the trimmer line by tapping the head on the ground. This convenient feature ensures continuous performance without needing to stop and manually adjust the line. Additionally, the dual line cutting system provides an optimized cutting area, resulting in faster work completion.

Husqvarna has integrated several cutting-edge technologies into these models for increased efficiency and ease of maintenance. The air purge system removes air from the carburetor and fuel system, facilitating smooth starting. The Smart Start technology reduces the resistance in the starter cord by up to 40%, making it easier to start the engine even in challenging conditions.

Both trimmers are also designed with durability in mind. The reinforced materials used in construction resist wear and tear, ensuring longevity in tough environments. The design further promotes effective cooling to enhance engine performance and prolong service life.
