9.1.2 Risk of explosion due to electrostatic charging
WARNING
Risk of explosion due to static charging
If you clean the machine with compressed air, plastic components may become statically
charged and create 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.
9.1.3 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.
9.1.4 First inspection
Perform the following checks after approximately 500 operating hours or one year, whichever
comes first:
