6. Examine the carbide insert that is in the mixing chamber. Replace the mixing chamber if you
find the following:
◦ Evidence of erosion, wear, or other damage such as pitting
◦ Hole is oblong shape instead of round
◦ Diameter of the hole is larger than 1.8 mm (0.07 in.)
7. Apply a thin, even layer of BLUE LUBRICANT on the angled surface of the orifice assembly
with a clean, lint-free applicator.
NOTICE
Do not over-tighten the cutting head—it will damage mating surfaces and the orifice
mount. Such damage is not covered by warranty.
8. Make sure that the seating surface that is in the mixing chamber is free of abrasive and debris,
and then drop the orifice assembly—flat face down, taper side up— into the recess of the body.
9. Apply a thin, even layer of BLUE LUBRICANT to the threads of the nozzle body. Attach the
mixing chamber body to the nozzle body, and then tighten to 41–48 N-m (30–35 ft-lb).
10. Clean the top surface of the cutting head clamp with a clean, lint-free cloth to remove abrasive
and debris.
11. Put the cutting head assembly in the clamp. Before you close the clamp, make sure that the
flat on the cutting head sits flush with the top of the clamp.
12. Connect the abrasive feed line.
