Risk of burn injuries due to hot surfaces
In operation, the temperature of individual machine parts can increase - and only decrease
slowly after switching off. You can burn yourself if you touch hot surfaces.
● Allow the machine to cool before starting any maintenance and service work on the machine.
● 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 specified 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
motor.
● Ensure that no foreign bodies are left in or on the motor.
● Securely attach all loose parts once you have completed the work.
● Carefully remove any dirt.
9.1.2 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.
