Live Online Training Maintenance, servicing and repair

Live Online Training: Maintenance, servicing and repair

Live Online Training combines the advantages of online and face-to-face trainings. It is streamed from the LESER Chatroom and performed according to the same standards as the face-to-face training. No matter from which location you participate - in the office, in the home office or in the workshop, in the practical part you even work on the safety valve yourself.


  • LESER will send you a training box with a LESER API safety valve. You do the maintenance included the disassembly, malfunction analysis as well as assembly by yourself
  • Demonstrations at the fully equipped assembly and test bench in the LESER Chatroom combine theory and practice
  • The communication between the participants is ensured by a fixed number of participants. During the training you are connected live with our trainers and other participants, you can ask questions and share information with each other
  • With successful final examination you will receive a certificate. During the Corona pandemic, this certificate is used as the basis for LARC certification in addition to face-to-face training

Be excited about our workshop together with the LESER Training Box.
