Manual Extract Disassembly General precautions
Hydraulic devices all consist of precision components and require extra attention during disassembly and assembly. Select a clean place to conduct the procedures.
The valve must be handled with utmost care to prevent dirt or soil from entering the inside.
After the valve has been removed from the hydraulic motor, the following must be done.
1. Place blanking plugs in the ports VA and VB.
2. Place labels (or adhesive strips) on mating faces.

Clean the assembly exterior before the start of disassembling to ensure a clean condition. Work should be carried out on a suitable work bench with a clean sheet of paper and rubber placed on top. Handle each part carefully to avoid any dents or scratches.
