STEP 2 – Removing Scalloped Flange

Remove scalloped adjusting flange from jet retaining
flange by pulling straight out of jet. If it does not easily
release from its snapped-in position, place the flathead
of a screwdriver between the jet flange and the scalloped
adjusting flange and carefully pry it loose.

STEP 3 – Breaking and Removing Old Jet Nozzle

The old jet nozzle will be broken into pieces when
removing. To do this, grip old jet nozzle tightly with needle
nose pliers at points shown, and firmly pull nozzle toward
you. This nozzle will most likely come out in pieces so be
sure to remove all pieces from jet body. Also, be careful not
to damage threads of jet body.

CAUTION

Threads can be damaged when removing old nozzle. If threads are damaged you may not be able to install
the new nozzle and the entire jet may have to be replaced. To avoid this hazard, follow nozzle removal
instructions closely and be sure all broken nozzle pieces are removed from the jet.

STEP 4 – Installing New Nozzle

Hold new nozzle with needle nose pliers by gripping
nozzle on hex pattern (not on orifice) and insert into jet
body. After nozzle is inserted, be sure nozzle is seated
properly and is rotated clockwise (looking into jet) until
it stops. You may need to push nozzle into final position
with your finger. This will help you to “feel” the seated
position of the nozzle.

STEP 5 – Installing Split Retaining Ring

Insert split retaining ring with adjusting boss facing outward by pushing first one end into jet body and then the
other. Be sure retaining ring has snapped into jet body behind jet retaining flange and is laying flat around hex of
nozzle. Thread on retaining ring must engage internal threads of jet body without crossthreading and turn freely.

STEP 6 – Adjusting the Split Retaining Ring

Rotate the split retaining ring in threads of jet body with tip of screwdriver until it touches the nozzle.
Additionally, turn the ring until drive leg slots in the ring expose the next set of openings on nozzle.
This is the proper adjustment for the retaining ring. Do not over tighten as this may cause damage to the jet or
cause the jet to not operate properly.

CAUTION

Do not over tighten split retaining ring. Over tightening the split retaining ring can cause damage to the jet, or cause
the jet to not operate properly. Tighten until alignment is reached and no further.

STEP 7 – Re-installing Scalloped Adjusting Flange

Re-install scalloped adjusting flange. Be sure that the retaining ring is adjusting as described in Step 6 so that
drive legs of adjusting flange will pass through slots in retaining ring.
