Risk of burn injuries as a result of hot surfaces
Individual machine parts can become hot in operation. Burns can result when coming into
contact with these parts.
• Never touch machine parts during operation.
• Allow the machine to cool down before starting work.
• Check the temperature of parts before touching them. If required, wear suitable protective
equipment.
Damage if the machine is not maintained
The machine can be damaged if it is not appropriately maintained. This can cause faults which
can result in eventual or immediate death, serious injury or material damage.
• Maintain the machine at the specied maintenance intervals.
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.
9.2.2 Inspections in the event of faults
Natural disasters or unusual operating conditions, such as overloading or short circuit, are faults
that overload the machine electrically or mechanically.
Immediately perform an inspection after such faults.
Note
Inspection specications
• Carefully comply with the relubrication intervals for rolling bearings that deviate from the
inspection intervals.
• When servicing a three-phase machine, it is generally not necessary to dismantle it. The
machine only has to be dismantled if the bearings are to be replaced.
