9.1 Inspection and maintenance
Damage from foreign bodies in the machine
Foreign bodies such as dirt, tools or loose components 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.
• Ensure that no foreign bodies are left in or on the machine.
• Securely attach all loose parts once you have completed the work.
• Carefully remove any dirt.
