Carbon	Check the carbon brush for wear. It is worn out
brushes	when more than half of its total length has been
	consumed. Check that it slides freely in the brush
	holder, that it is pressed correctly by the spring and
	that the spring is still elastic.
	Ensure that the surface along which the carbon
	brushes slide is evenly and highly polished and
	that any lines or porosity are extremely small and
	of similar dimensions.
	Check the wire for wear and ensure that the
	connection terminals are well tightened.
	Ensure that there are no big lines, deep grooves,
	craters, burns or splinters on the carbon brush
	edge and that all the carbon brushes are worn in
	the same way.
	Check the housing for wear and clearance.
	Brushes usually last from 6 months to 1 year,
	depending on use.
	Check the carbon brush and coupling pressure.
	When the warning light turns on, the carbon
	brushes need to be replaced, even if 300 hours
	have not been reached.
Terminals	Check that supply bolt nuts are well tightened and
	that the insulating materials are in good condition.
Fan	Ensure that air intakes are not clogged and that the
	fan turns freely.
Bearings	Check the temperature and the vibration and noise
	degree.
Insulation	Use a megger, especially when the environment is
	wet, to check the insulation value: it should never
	be less than 2 MOhm.
Screws	Check that the screws are not loose.
	Check that there are no faulty contacts in the
	electrical connections which could lead to local
	overheating.
Windings	General cleaning. Check that the insulation to
	ground is less than 2 MOhm.
