RPS GEAR DRIVEN SPRINKLER SETTING INSTRUCTIONS
CHANGING A NOZZLE
1
REMOVING THE NOZZLE RETENTION SCREW
Use the hex key end “A” of the universal tool to remove
the nozzle retention screw by turning counter-clockwise
to remove and clockwise to re-install.
2
PULL UP THE RISER
Insert the “B” end of the universal tool in the keyhole on the
top of the nozzle turret 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. Hold the riser assembly with one hand.
3
REMOVING THE NOZZLE
With the nozzle retention screw removed, the nozzle may
be removed by either turning on the water (wear safety
glasses when using this method), or by pulling outward
on the nozzle prongs with a pair of needle-nose pliers.
4
INSTALLING A NOZZLE
Press the desired nozzle into the nozzle socket. Make
sure the nozzle number is visible and the nozzle “prongs”
are up. Then, re-install the nozzle retention screw.
NOTE: The nozzle retention screw is also a break-up
screw and used to adjust the distance of the spray.
SETTING THE ARC ADJUSTMENT
NOTE: The RPS gear driven sprinkler has a fixed right start
and an adjustable left stop.
1
POSITIONING NOZZLE TURRET TO ITS “RIGHT START”
Place your finger on the top center of the nozzle turret.
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.
NOTE: The RPS is factory preset with a 180° arc setting, and includes a pre-installed #3 nozzle.

ADJUSTING THE RIGHT (FIXED) SIDE OF ARC
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 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 counter-clockwise and remove the internal riser assembly from the can. Once removed with
nozzle turret at its “right start,” reposition riser assembly so that nozzle arrow points to the desired start position.
Replace 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.
