MAINTENANCE

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.

The cooling system consists of:

1Air intake on the starter.

2Fins on the flywheel.

3Cooling fins on the cylinder.

4Cylinder cover (directs cold air over the cylinder).

Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder.

Spark plug

The spark plug condition is influenced by:

•Incorrect carburetor adjustment.

•A dirty air filter.

These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.

If the machine is low on power, difficult to start or runs poorly at idle speed: always check the spark plug first before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0,6-0,7 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.

CAUTION! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is fitted with a suppressor.

Two-piece shaft

The drive shaft end in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive shaft ends (splined coupling) on models with two-piece shafts will seize if they are not lubricated regularly.

Air filter

The air filter must be regularly cleaned to remove dust and dirt in order to avoid:

•Carburettor malfunctions

•Starting problems

•Loss of engine power

•Unnecessary wear to engine parts

•Excessive fuel consumption.

Clean the filter every 25 hours, or more regularly if conditions are exceptionally dusty.

Cleaning the air filter

Remove the air filter cover and take out the filter. Wash it clean in warm, soapy water. Ensure that the filter is dry before refitting it.

An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced.

If the machine is used in dusty conditions the air filter should be soaked in oil. See instructions under the heading Oiling the air filter.

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.
