To keep your Husqvarna grass trimmer and brushcutter in good condition, make sure you clean the cooling system.
For this you will need:
Protective gloves
Cleaning brush
The parts of a cooling system are:
the air intake on a starter (1)
the fins on a flywheel (2)
the cooling fins on a cylinder (3)
the cylinder cover (4)
muffler cover (5)
muffler plate (6)
Clean the cooling system with a brush once a week, or more frequently if necessary.
Make sure that the cooling system is not dirty or blocked.
