A. APPENDIX • ACTIONS TO FACE MALFUNCTIONS

A1. Introduction

- 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.
- In each point, we develop all the possible causes of the exposed malfunction. Depending on the possible origins of the event, the solution will require more
or less checks.
- Hereafter, we summarize a description of each one of the valve block controls on which we will have to come into contact with in order to try to solve the
incident. In order to have a greater control over the tasks of regulation and assembly of the hydraulic power unit, it is necessary to thoroughly read the
Technical Manual included with the MP hydraulic product.
