oriented .
– Use a medium adjustable wrench to loosen the adapter lock nut .
– Remove both the adapter and the lock nut .
ƒ Atomizer or quill
– If using a quill or atomizer nozzle with a specific orientation, use a permanent marker to mark the shaft to
show which direction the quill or nozzle is oriented .
– If fluid inlet does not have wrench flats, use a ¼" NPT nipple threaded into the fluid inlet adapter to remove
the adapter from the shaft . If the adapter has a multi-port valve, you can use the existing assembly to aid in
removal .
d. Loosen the collet and slide the shaft out of the body of the holder .
2. Separate the upper and lower body of the holder .
