g35 & g75 RiSeRS
To view and replace the nozzles, it is necessary to compress the riser spring by grabbing the riser seal assembly (g 27
above), pressing downward and then holding riser rmly to prevent the spring from moving upwards.
The G35 nozzles are yellow with single orices. The G75 nozzles are color-coded with two orices. All nozzles are retained
in the nozzle housing (turret) with a setscrew (g 30). Each setscrew has a
3
⁄32 inch Allen wrench recess at the top.
On the G35 or G75 rubberized logo cap, locate the arrowhead shaped area directly above the nozzle (g 31). Insert
the metal end of the Hunter wrench or a
3
⁄32 inch wrench into the membrane within the arrow that is directly above the
nozzle to be replaced. Engage the setscrew and turn counter-clockwise until the bottom of the setscrew clears the
top of the nozzle.
Note the nozzle’s orientation prior to removal to aid in the nozzle installation process. Using needle-nose pliers, grab
the right side of the nozzle on its outer ring and pull outward to remove the nozzle. In some cases it may be necessary
to grab the nozzle’s orice to remove the nozzle. Discard the old nozzle as the removal process can damage the
nozzle and negatively affect the performance.
Insert the replacement nozzle into the nozzle housing with the smaller orice positioned to the right. Press rmly
until it stops. Turn the nozzle-retaining setscrew clockwise while making sure that the setscrew does not distort the
nozzle. Lower the setscrew in front of the nozzle only as far as necessary to prevent nozzle movement. Take care not
to position the setscrew in front of or against the nozzle’s orice as performance can be negatively affected.
If the nozzle size or color has been changed, please note that the adjustable stator will likely need to be reset. Refer
to the Stator Adjustment section in this manual for information on how to reset the stator.
