6. Unscrew the end cap from the cylinder by hand;
make sure the check valve assembly and the end
cap turn as an assembly.
Note:
If the check valve and end cap do not turn to-
gether, the check valve body o-rings can be dam-
aged. If necessary, use a wrench.
7. Check the corners of the wrench flats on the main
body, and file off any burrs to prevent scratching the
end cap bore during removal.
8. Use your thumbs to press the check valve body out
through the end cap. The only resistance you should
feel is when the o-rings on the main body contact
the inner bore of the end cap.
9. Remove the retaining screw. Remove the support as-
sembly and inlet poppet.
10. Clean all parts in a non-residue solvent and allow
them to air dry before reassembly. Clean each part
separately to prevent damaging parts.
11. Inspect the main body o-rings. If the o-rings show
signs of damage, replace them and check the pas-
sages in the main body for debris.
12. Inspect the sealing surfaces on the main body for
erosion, cracks, or other damage. Replace the main
body if required.
