Servicing Reed Valves
Quincy compressor valve plates and reed valves should be inspected and
cleaned on a regular basis. The reed valves are made of stainless steel and can
be cleaned with a stiff bristle brush (not a wire brush!). A clean safety solvent
may also be used to loosen carbon deposits on the valve plates and reed valves.
Handle all parts with care; do not bend, mar or scratch any sealing surfaces.
