MAINTENANCE

Oiling the air filter

Always use HUSQVARNA filter oil, order no. 503 47

73-01. 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 the 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 on the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom.

Spark plug

Two-part shaft

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

NOTE: Use only JONSERED replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by JONSERED.

Maintenance schedule

Below you will find some general maintenance instructions.

The condition of the spark plug is affected by:

•An incorrect carburetor setting.

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

•A dirty air filter.

These factors cause deposits on the spark plug electrode that may result in malfunction or starting difficulties.

0,5 mm

Daily maintenance

•Check throttle trigger and throttle trigger lockout function.

•Check stop switch function.

•Check that blade/trimmer head does not rotate at idling.

•Clean the exterior of the machine.

•Check that the harness is undamaged.

•Check the blade guard for damage or cracks.

•Change the guard in case of impacts or cracks.

•Check the trimmerhead for cracks and chips or damage. Replace if necessary.

•A non-balanced blade/trimmer head induces heavy vibrations that may damage the machine.

•Check that the blade nut is sufficiently tightened.

•Check that nuts and screws are sufficiently tightened.

Weekly maintenance

If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.

If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.

NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.

Angle gear

The angle gear is filled with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use JONSERED special grease.

Normally, the grease does not need to be changed except when the angle gear is repaired.

•Check the starter, especially cord and return spring.

•Clean the carburetor area.

•Clean the exterior of the spark plug.

•Remove it and check the electrode gap.

•Adjust it to 0,5 mm (.020"), or change the spark plug.

•Clean the cooling fins on the cylinder and check that the air intake at the starter is not clogged.

•Check that the angle gear is filled with grease up to 3/4. Use special grease.

•Clean the air filter.

•Clean or replace the muffler’s spark arrest screen (not on mufflers with a catalytic converter).

Monthly maintenance

•Clean the fuel tank.

•Clean the exterior of the carburetor and the space around it.

•Clean the fan and the space around it.

•Check fuel hose for cracks or other damage. Change if necessary.

•Change fuel filter in fuel tank.

•Check clutch, clutch spring and clutch drum for wear. Change if necessary.

•Check electrical wires and connections.

•Change the spark plug.

•Change the airfilter.

•Check and clean the muffler’s spark arrest screen if necessary (only mufflers with a catalytic converter).
