Concrete safety instructions 
and applied symbols 
 
Concrete safety instructions are provided in the 
following operating instructions which will point out 
any unavoidable remaining risks during the machine 
operation. These remaining risks contain hazards for: 
 
Persons 
Product and machine 
The environment 
 
Symbols used in the operating instructions should 
draw attention to the safety signs! 
 
This symbol points out that specifically 
personal injury risks may be anticipated (Mortal 
danger, risk of injuries). 
This symbol signifies that especially 
hazards for the machine, material and the 
environment may be encountered. 
 
The most important objective of the safety signs 
exists in the prevention of personal injuries. 
If the warning triangle with the wording “danger” is on 
a safety notice, hazards for the machine, material and 
the environment are not excluded. 
If the warning triangle with the wording “caution” is on 
a safety reference, personal injuries are not 
anticipated. 
 
The applied symbol cannot replace the text of the 
safety reference. The text must therefore always be 
completely read! 
 
Basic safety measures during normal 
operations: 
 
The machine may only be operated by trained and 
authorized personnel who know the operating

Basic safety measures during service 
and maintenance: 
Adhere to the inspection and maintenance intervals 
specified in the operating instructions! 
 
Block access to the work area of the machine

maintenance or repairs! Attach or set up a warning 
sign that points out maintenance or repair work! 
 
  Pull the power plug prior to any maintenance 
or repair work or switch off the main switch for the 
power supply and secure with a lock, if the power 
supply is installed. 
The key to this lock must be in the hands of the 
person that is completing the maintenance or repair 
work! Only use perfect load suspension and lifting 
equipment when replacing heavy machine parts! 
 
  Properly dispose of environmentally 
hazardous lubricants, coolants or cleaning agents!
