  • Page 25: Appendix • Actions To Face Malfunctions

    - The aim of this document is to let you know the procedures to follow in case of malfunctions that may occur in the handling during procedures such as installation, start up or maintenance of any of MP drive equipment, whatever type they are.
  • Page 26 MP sava3 Hidraulic Power Unit 1 ¼” 1 ½” Disposal of the return pipes in the valve block. - The return pipes are small union joints on the lower side of the valve block (open the tank’s level cap and have a look at the aforementioned side in order to identify them) where the hydraulic oil flows through during the different operations of this valve block.

  • Page 33: At Floor

    MP sava3 Hidraulic Power Unit 1 ¼” 1 ½” 4. At floor A4.1.The lift descends continuously - Descent valve (Locking seal) - The seal of the descent piston is not watertight. The problem can be clearly detected when there is rapid balancing. To assure ourselves of this, we must remove the right cap of the hydraulic power unit (level cap) and the transparent sheaths of the return pipes in the valve block.

  • Page 34: A4.2.The Lift Descends When Loaded

    - The existence of air inside the cylinder may cause an effect that is easy to identify. When a load is introduced, it causes a spring-like response in the system.  Bleed the cylinder to get rid of any air inside it (see the technical manual for the MP hydraulic cylinder MTHDCMP). - Hydraulic oil.
  • Page 35 MP sava3 Hidraulic Power Unit 1 ¼” 1 ½” NOTES: - It is necessary to bleed the installation after any change of fittings. - The usual amount of leakage through the cylinder joint is between 0,5 and 1 L per month.
