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:

1Cooling ﬁns on the cylinder.

2Cylinder 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.

•An incorrect fuel mixture (too much or incorrect type of oil).

•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 0.7 mm (0,028"). 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.

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.

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 distribute the oil. Squeeze the 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.
