Safety instructions 

 

WARNING! 

If  a  fault  occurs  which  represents  a  risk  to  personnel,  equipment  and/or 
their  surroundings;  the  equipment  and  all  work  MUST  BE  STOPPED 
immediately.  It  must  also  be  ensured  that  it  is  not  possible  to  turn  on  the 
equipment again until the fault is cleared and made safe. 

The  equipment  should  only  be  used  the  unit  again  once  the  cause  of  the 
fault  has  been  traced  and  there  is  no  longer  any  danger  represented  to 
personnel, equipment and/or their surroundings. 

Faults  can  only  to  be  corrected  repaired  or  eliminated  by  qualified  staff, 
which  observe  and  implement  all  of  the  relevant  safety  instructions. 

 

Chapter 2 

Following  a  fault,  the  equipment  can  only  be  put  back  into  service  after  it 
has been checked by and approve by suitably qualified staff.
