Wiping cloths or rags should not be used to dry parts. Lint may be deposited on the parts which may cause later trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. All disassembly and all assembly procedures must be performed on a clean work surface and in a clean hydraulic area. Keep cleaned parts covered and protected at all times.Note: Only a portion of the items in the process are serviceable parts. All parts must be disassembled and assembled in order to obtain access to the serviceable parts.Note: O-ring seals, gaskets, and seals should always be replaced. A used O-ring seal may not have the same sealing properties as a new O-ring seals. Use Tooling (A) during the assembly procedure.Note: DO NOT mix parts from one pilot valve to another pilot valve.
