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.
