RPS
50 Gear Driven Sprinkler Setting Instructions
®
NOTE: The RPS 50 is factory preset with a 40° arc setting, and includes a pre-installed #1.5 nozzle.
CHANGING A NOZZLE
1
REMOVING THE NOZZLE RETENTION SCREW
Use the Key (A) to remove the nozzle retention screw (B) by turning
counter-clockwise to remove or clockwise to re-install.
2
PULL UP THE RISER
Insert the Key (A) in the keyhole (C) on the top of the nozzle turret (D)
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 (E). Hold the riser assembly with one hand.
3
REMOVING THE NOZZLE
STANDARD NOZZLE PERFORMANCE
With nozzle retention screw removed, the nozzle may be removed by
either turning on the water (wear safety glasses when using this method),
U.S.
or by pulling outward on nozzle wing (F) with a pair of needle-nose pliers.

INSTALLING A NOZZLE
#3
30
Press the desired nozzle (G) into the nozzle socket (E). Make sure the
40
nozzle number is visible and the nozzle wing (F) are up. Then, re-install
50
the nozzle retention screw (B). NOTE: The nozzle retention screw is also
60
a break-up screw and used to adjust the distance of the spray.

SETTING THE ARC ADJUSTMENT
50
60
NOTE: The RPS50 Gear Driven Sprinkler has
#0.75
a fixed right start and an adjustable left stop.

1
POSITIONING NOZZLE TURRET TO ITS "RIGHT START"
60
Place your finger on the top center of the nozzle turret (D). Rotate the
#1
30
turret counter-clockwise to the left stop to complete any interrupted
40
rotation cycle. Rotate the nozzle turret clockwise to the right start.
50
This is the fixed side of the arc. The nozzle turret must be held in this
60
position for arc adjustments. The right start does not change.
#2

40
ADJUSTING THE RIGHT (FIXED) SIDE OF ARC
50
If the right side of the arc is not properly aligned, sprinkler may
60
spray in areas not intended for watering such as driveways or
#4
30
adjacent properties. The right side arc can easily be realigned.
40
50
OPTION 1: REPOSITION CAN ON THE FITTING
60
Turn the housing can left or right to the desired position.
#6
30
This may require temporary removal of the soil around the
40
sprinkler to allow you to grip the sprinkler can.
