Safety instructions
Dangerous situations during operation can be avoided by safety-conscious and
proactive behaviour of the personnel.
For operation, the following principles apply:
•
Monitor the component during operation.
•
Safety devices must not be changed, removed or taken out of service. Check
all safety devices at regular intervals.
•
All guards and hoods must be fitted as intended.
•
The installation location of the component must always be properly ventilated.
•
Structural changes to the component are not permitted. Report any changes
to the component immediately to the person in charge.
•
Always keep danger zones clear. Do not leave any objects in the danger
zone. Only allow persons to enter the danger zone when the machine is de-
