Maintenance
9.1 Inspection and maintenance
Machine damage
If the machine is not maintained it can suffer damage. This can cause faults which can result
in eventual or immediate death, serious injury or material damage.
Perform regular maintenance on the machine.
Dust disturbances when working with compressed air
When cleaning with compressed air, dust, metal chips, or cleaning agents can be whirled up.
Injuries can result.
When cleaning using compressed air, make sure you use suitable extraction equipment and
wear protective equipment (safety goggles, protective suit, etc.).
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
● Securely attach all loose parts again once you have completed the maintenance
● Carefully remove any dirt.
Note
Operating conditions and characteristics can vary widely. For this reason, only general
intervals for inspection and maintenance measures can be specified here.
