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 450R gear driven sprinkler has a fixed right start and an ad-
justable 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.
2. 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.
450R ROTOR SETTING INSTRUCTIONS
NOTE: THE 450R IS FACTORy PRESET WITH A 180° ARC SETTING, AND INCLUDES A PRE-INSTALLED #3 NOZZLE.

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.
3. ADJUSTING THE LEFT (VARIABLE) SIDE OF THE ARC
INCREASING THE ARC: Insert the plastic key end “D” of the universal tool into
the arc set adjustment slot. While holding the nozzle turret at the “right start,” turn
the universal tool clockwise. Each full 360° turn of the universal tool will increase the
arc 90°. Adjust to any arc between 40° and 360°. The universal tool will stop turning,
or there will be ratcheting noise, when the maximum arc of 360°
has been reached.
DECREASING THE ARC: Insert the plastic key end “D” of the
universal tool into the arc set adjustment slot. While holding the
nozzle turret at the right start, turn the universal tool counter-
clockwise. Each full 360°
turn of the universal tool will decrease the arc 90°. Adjust to
any arc between 40° and 360°. The universal tool will stop turning, or
there will be a ratcheting noise, when the minimum arc of 40° has
been reached.
SPRINKLER INSTALLATION
1. INSTALL AND BURy
Do not use pipe dope. Thread the sprinkler on the pipe. Bury the
sprinkler flush to grade. NOTE: Gear driven sprinklers and pop-up
sprays should not be installed on the same watering zone.
2. INSPECTING THE FILTER
Unscrew the top and lift the complete sprinkler assembly out of the
housing can. The filter is located on the bottom of the sprinkler as-
sembly and can be easily pulled out, cleaned and re-installed.
3. WINTERIZATION TIPS
When using an air compressor to remove water from the system
please note the following:
a) Do not exceed 30 PSI.
b) Always introduce air into the system gradually to avoid air pres-
sure surges. Sudden release of compressed air into the sprinkler
can cause damage.
c) Each zone should run no longer than 1 minute on air. Sprinklers
turn 10 to 12 times faster on air than on water. Over spinning rotors
on air can cause damage to the internal components.
