Note: Cleanliness is an important factor. Before assembly, all parts should be thoroughly
cleaned in cleaning fluid. Allow the parts to air dry. 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. Dirt and other
contaminants can damage the precision components. All disassembly and all assembly
procedures must be performed on a clean work surface and in a clean area. Keep cleaned
parts covered and protected at all times.
Note: O-ring seals, gaskets, and seals should always be replaced. A used O-ring may not
have the same sealing properties as a new O-ring seal. A reconditioning procedure should
