• The actuator is not allowed to be used outside the specified field of application, especially in
aircraft or any other form of air transport.
• Assembly must be carried out by trained personnel. Any legal regulations or regulations
issued by authorities must be observed during assembly.
• The mechanical end stops for restricting the angle of rotation are only allowed to be removed
for adjustment purposes. It is essential for them to be in place during operation.
