Personal protective measures 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.).
CAUTION
Cleaning with compressed air
If cleaning is performed using compressed air, chips of metal can be blown into the winding
head. This can damage the insulation, and result in clearances and creepage distances less
than the minimum allowable. This may cause damage to the machine extending to total failure.
When cleaning with compressed air, ensure there is adequate extraction.
CAUTION
Foreign bodies in and on the machine
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 bodes 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.
Risk of explosion when cleaning with compressed air
If you clean the machine with compressed air, plastic components may become statically
charged and ignite a potentially explosive atmosphere; an explosion can occur. This can
result in death, serious injury or material damage.
Do not use compressed air to clean plastic parts in an explosive atmosphere. When cleaning
the machine, make sure that the air in the vicinity of the motor is free of gas and dust.
