Nozzle Replacement - G80 Risers - Hunter G835 Owner's Manual

nozzle RePlACeMenT – g80 RiSeRS
to view and replace the nozzles, it is necessary to compress the riser spring by grabbing the riser seal assembly
(fig 32), pressing downward and then holding riser firmly to prevent the spring from moving upwards.
the g80 riser has three color-coded opposing nozzles. all g80 nozzles are retained in the nozzle housing by the
shroud (fig 33) that covers the nozzle housing (turret). to remove the shroud, use a phillips head screwdriver and
remove the stainless steel screw at the top of the riser by turning it counter-clockwise. prior to removal of the shroud,
take note that the large nozzle arrow on top of the shroud's rubberized logo cap is orientated directly over the larger,
long-range nozzle (fig 34). this will help with the shroud installation process later.
While firmly holding the compressed spring and seal assembly downward, grab and lift the shroud off the nozzle
housing (fig 35). If preferred, slowly lift and release the compressed spring and seal assembly then remove them from
the riser assembly. note the orientation of the seal assembly for installation later. or alternatively, continue to firmly
hold the compressed spring and seal assembly downward while removing and replacing nozzles.
to remove the g80 long-range primary nozzle, use needle-nose pliers to grab the nozzle's orifice then pull
outward (fig 36). discard the old nozzle as the removal process can damage the nozzle and negatively affect the
performance. prior to nozzle replacement, note that there is a notch (recessed area) on the nozzle's outer ring. Insert
the replacement nozzle into the nozzle housing with this recess positioned at the top. the correct orientation of the
recessed area is important as it is part of the g80's nozzle retention system. press in firmly until the nozzle stops.
the g80's short-range and mid-range nozzles are performance matched to all g80 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 with the correct orientation for optimal performance.
prior to removal of the short-range or mid-range nozzle, note the differences between the nozzle on the left and
right. When facing the short-range and mid-range nozzles:
• G80 Full Circle - The short-range nozzle is black and on the right side
- the mid-range nozzle is blue and on the left side.
to remove the short or mid-range nozzle, grab and rotate the nozzle 90 degrees to the outside (away from turret)
then wiggle and pull it upward. to install a short-range or mid-range nozzle, position the nozzle so the orifice is
pointing outward and to the side. drop the nozzle into position by wiggling it downward. the final step is to rotate
the nozzle 90 degrees pointing it in the opposite direction of the primary long-range nozzle. this action locks the
nozzle in the nozzle housing.
prior to installation of the shroud, replace the retraction spring and seal assembly (if removed prior). to install the
nozzle housing shroud, position the shroud over the nozzle housing. the single opening for the primary long-range
nozzle in the shroud must be positioned directly over the nozzle. press into position and confirm all three nozzle
openings are lined up with the nozzles inside. Install the stainless steel screw into the rubberized logo cap by turning it
clockwise until hand tight. 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.
