Nozzle Replacement - G95 Risers - Hunter G835 Owner's Manual

nozzle RePlACeMenT – g95 RiSeRS
to view and replace the nozzles, it is necessary to compress the riser spring by grabbing the riser seal assembly
(fig 37), pressing downward and then holding riser firmly to prevent the spring from moving upwards.
the g95 riser has three color-coded nozzles that all face the same direction. all g95 nozzles are retained in the nozzle
housing (turret) with three setscrews (fig 40). each setscrew has a 3⁄32 inch allen recess at the top. Insert the metal
end of the Hunter wrench or a 3⁄32 inch wrench into setscrew that is 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 (fig 41).
to remove the long-range primary nozzle, first note the nozzle's orientation prior to removal. the g95's primary nozzle
has a protruding rail that must engage the slot on the right side of the nozzle opening. understanding this will help
during the installation process later. using needle-nose pliers, grab the nozzle's outer ring next to the recess on the
right side of the nozzle opening and then pull outward (fig 42). If necessary, grab the nozzle's orifice to gain a better
grip. 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. press firmly until the nozzle 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 orifice 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.
the g95's short-range and mid-range nozzles are performance matched to all g95 long-range nozzles. as a result,
replacement of these nozzles is normally required only when a nozzle has been damaged. If replacement does
become necessary, it is important to note that these nozzles must be installed in the correct orientation for optimal
performance.
prior to removal of the g95's short-range or mid-range nozzle, note the differences between the nozzle on the left
and right.
• G95 Adj. Arc - The short-range nozzle is black and on the left side. (fig 40)
Note - In 2010, the short-range nozzle will change to red.
using needle-nose pliers, grab the nozzle's orifice then pull outward. discard the old nozzle as the removal process
will damage the nozzle and negatively affect the performance. Insert the replacement nozzle into the nozzle housing
and press firmly until it stops. turn the nozzle-retaining setscrew clockwise to a position in front of the nozzle that
prevents nozzle movement. take care not to position the setscrew in front of or against the nozzle's orifice as
performance can be negatively affected.
