Maintenance

Change coolant

Correct coolant level is important for the cooling system to function properly. Therefore the coolant level must be checked regularly.

The coolant should be visible when the filler cap is removed.

Repeated coolant loss normally indicates leakage. The cooling system should be checked by a professional. It is not sufficient just to top up with coolant.

If the engine boils, coolant will be lost. Open the radiator cap and allow the coolant to cool down. Allow the engine cool before filling.

The cooling system must not be filled with salt water, as this will cause corrosion damage to the engine.

Replace coolant if it is discoloured or cloudy

The cooling system must then be thoroughly flushed.

Use only glycol-based antifreeze approved to BS 6580:1992 or ASTM D 3306-89 or AS 2108-1977 (indicated on the packaging).

The antifreeze must be intended for alloy engines.

Your Husqvarna supplier can provide the right type of antifreeze.

Use antifreeze all year round and even in climates where there is no risk of frost.

Antifreeze contains additives that protect the engine cooling system against corrosion

The coolant and antifreeze should be changed at least every two years.

WARNING! Do not open the cap quickly

!when the engine is hot without first releasing the pressure by partially opening the cap. Risk of burns. Wear protective gloves and goggles.

WARNING! Antifreeze and coolant are

!dangerous to health. Keep them in storage in labelled containers and away from children and animals.

When emptying loosen the lower hose to the radiator.

Remove the filler cap.

Fill only with antifreeze and water mixed according to the following table.

IMPORTANT! Never add cold coolant to a hot engine. Risk of comprehensive engine damage.

Check the coolant when the engine has run for a few minutes after filling. There may have been air in the system that has been released.
