Lint may be deposited on the parts which may cause trouble. Inspect all parts. If any parts are worn or damaged, use new parts for replacement. Dirt and other contaminants can damage the precision component. Perform assembly procedures on a clean work surface. Keep components covered and protected at all times.Note: Check the O-ring seals, the gaskets, and the seals for wear or for damage. Replace the components, if necessary.
