Start the cleaning with
distilled water and a ¼” wood dowel with the tip cut to a chisel point.
Rub the dowel tip across
the acceleration & collection nozzle slits until all the debris has
been scrubbed off.
Rinse with distilled
water.

Clean the dowel tip by
cutting a new chisel tip.
On the reverse side of
the acceleration & collection nozzle slits, use the dowel tip to clean
the slit.
Rinse with distilled water.

Note: All three O-rings are interchangeable.

|
Use a single edge razor
blade to clean the inside edges of the slits.
Do not use any metal object that does not easily fit
into the slit - doing so will damage the slit.
Do a final rinse by
squirting water through the slits, wipe and/or blow dry.
Reassemble, reinstall and
leak check the PC system.
