75 Gear Driven Sprinkler Setting Instructions
®
NOTE: The RPS 75 is factory preset with a 180° arc setting, and includes a pre-installed #3 nozzle.
CHANGING A NOZZLE
1
REMOVING THE NOZZLE RETENTION SCREW
Use the hex (B) end of the Key to remove the nozzle retention screw
by turning counter-clockwise to remove or clockwise to re-install.
PULL UP THE RISER
2
Insert the (A) end of the Key in the keyhole (L) on the top of the nozzle
turret (I) and turn the key 1/4 turn to insure that the key does not slip out
of the keyhole when you pull it up. Firmly pull up the entire spring-loaded
riser to access the nozzle socket (G). Hold riser assembly with one hand.
3
REMOVING THE NOZZLE
With nozzle retention screw removed, the nozzle may be removed by
pulling outward on the nozzle prongs (D) with a pair of needle-nose pliers.
4
INSTALLING A NOZZLE
Press the desired nozzle (C) into the nozzle socket (G). Make sure
the nozzle number is visible and the nozzle "prongs" (D) are up. Then,
re-install the nozzle retention screw (F). NOTE: The nozzle retention
screw is also a break-up screw, used to adjust the distance of the spray.
SETTING THE ARC ADJUSTMENT
NOTE: The RPS75 Gear Driven Sprinkler has a fixed right start and
an adjustable left stop.
1
POSITIONING NOZZLE TURRET TO ITS "RIGHT START"
Place your fingers on the top center of the nozzle turret (I). Rotate the
turret counter- clockwise to the left stop to complete any interrupted
rotation cycle. Rotate the nozzle turret clockwise to the right start.
This is the fixed side of the arc. The nozzle turret must be held in this
position for arc adjustments. The right start does not change.
ADJUSTING THE RIGHT (FIXED) SIDE OF ARC
2
If the right side of the arc is not properly aligned, the sprinkler may
spray in areas not intended for watering such as driveways or adjacent
properties. The right side arc can easily be realigned.
OPTION 1: REPOSITION CAN ON THE FITTING
Turn the sprinkler can (K) and the fitting below it left or right to the
desired position. This may require temporary removal of the soil around
the sprinkler to allow you to grip the sprinkler can.
OPTION 2: REMOVE INTERNAL RISER ASSEMBLY AND REPOSITION
Unscrew the top (H) counter-clockwise and remove the internal riser
assembly from the can. Once removed with nozzle turret (I) at its right
start, reposition the riser assembly so that nozzle arrow points to the
desired start position. Replace the riser assembly back in the can and
screw on the top. At this point you have realigned the right arc stop,
and you can adjust the left arc to an appropriate setting.
