Testing.
WARNING
Fuel from the spray orifices can penetrate clothing and skin causing serious personal injury.
The nozzle tip should always be directed away from the operator. Enclosing the nozzle in a
transparent cover is recommended.
(1)
Use special tool (item 7, section III, appendix B) or (item 8, section III, appendix B) to test nozzles.
Figure 6-8. Nozzle Testing
(a)
If nozzle tester (item 7, section III, appendix B) (Figure 6-8, 2) is used, see test setup A. Use the
KJD10109 fuel line (1) and connect line to tester (2) and nozzle (3).
(b)
If nozzle tester (item 8, section III, appendix B) (6) is used, see test setup B. Use Y-900-3, Y-900-5
adapters (4) and Y-900-2 Fuel Line (5) from D-01110AA Adapter Set to connect nozzles to D-01109AA
Nozzle Tester (6).
WARNING
Before applying pressure to the nozzle tester, be sure that all connections are tight, and that
the fittings are not damaged. Fluid escaping from a very small hole can be almost invisible.
Use a piece of cardboard or wood, rather than hands, to search for suspected leaks.
(2)
Position tip of nozzle below top of beaker (7) and back out 30° from vertical. This is necessary to contain
all spray in beaker (7), as nozzle spray pattern is at an angle to the nozzle centerline. Leave connections
slightly loose.
