!
In countries that have a warm and dry climate there is a significant risk of fire. We therefore fit certain mufflers with a spark arrestor screen. Check whether the muffler on your machine is fitted with this kind of screen.
For mufflers it is very important that you follow the
uctions on checking, maintaining and servicing your
instr machine.
Never use a machine that has a faulty muffler.
Regularly check that the muffler is securely attached to the machine
.
WARNING! The inside of the muffler contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged muffler.
WARNING! Bear in mind that: The exhaust fumes from the engine are
hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material!

Locking nut

A locking nut is used to secure some types of cutting attachment.
When fitting, tighten the nut in the opposite direction to the direction of rotation of the cutting attachment. To remove it, undo the nut in the same direction as the cutting attachment rotates. (CAUTION! The nut has a left-hand thread.)
When loosening and tightening the saw blade nut, there

Carburetor

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 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.

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system.
The cooling system consists of: 1 Air intake on the starter. 2 Fins on the flywheel. 3 Cooling fins on the cylinder. 4 Cylinder cover (directs cold air over the cylinder). Clean the cooling system with a brush once a week, more

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

If the machine is low on power, difficult to start or runs poor 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.

MAINTENANCE
Oiling the air filter
Always use HUSQVARNA filter oil, art. no. 531 00 92-48. The filter oil contains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact.
Put the filter in a plastic bag and pour the filter oil over it. Knead the plastic bag to distr excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter to the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom.
