Maintenance
NOTICE
Damage to insulation
If metal swarf enters the winding head when cleaning with compressed air, this can
damage the insulation. Clearance and creepage distances can be undershot. This
may cause damage to the machine extending to total failure.
When cleaning with compressed air, ensure there is adequate extraction.
NOTICE
Machine damage caused by foreign bodies
Foreign bodies such as dirt, tools or loose components, such as screws etc., can be
left by accident inside the machine after maintenance is performed. These can
cause short circuits, reduce the performance of the cooling system or increase
noise in operation. They can also damage the machine.
When carrying out maintenance work, make sure that no foreign bodies are left
•
in or on the machine.
Securely attach all loose parts again once you have completed the maintenance
•
procedures.
Carefully remove any dirt.
