The condition of the spark plug is affected by:
Below follows some general maintenance instructions.
If you need further information please contact your service workshop.
•An incorrect carburettor setting.
•An incorrect fuel mixture (too much or faulty oil).
•A dirty air filter.

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 HUSQVARNA special grease.
Normally, the grease does not need to be changed except when repairs are carried out.
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.
4.Check that the cutting |
head does not rotate while |
idling. |
5.Clean the air filter. |
Replace if necessary. |
6.Check that the guard is |
undamaged and not |
cracked. Replace the |
guards if they have been |
exposed to impact or are |
cracked. |

head is undamaged and |
not cracked. Replace the |
trimmer head if necessary. |
