CHANGING A NOZZLE
1REMOVINGTHE NOZZLE RETENTION SCREW
Use your K-Key or a flat blade screwdriver to remove the nozzle retention
screw by turning counter-clockwise to remove and clockwise to re-install.
2PULL UP THE RISER
Insert the K-Key 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 up with one hand.
3REMOVING THE NOZZLE
With the nozzle retention screw removed, insert the K-Key into the slot
directly under the nozzle “prongs” at the top of the nozzle. Now, turn the
key 1/4 turn to “hook” the nozzle and pull the nozzle out.
4INSTALLING 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
1FINDING THE LEFT START POSITION
Place your finger on the top center of the nozzle turret. Rotate the
turret to the right until it stops and then back to the left until it stops.
Notice the position of the nozzle arrow.This is the “Left Start” position.
The sprinkler will begin spraying from this position and rotate clockwise
until it reaches the right Adjustable Stop-Return Point.
2ORIENTING THE LEFT START POSITION
Insert the K-Key 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. Being careful not to allow the nozzle turret to turn,
firmly pull up the entire spring-loaded riser. Hold the lower riser assembly
up with one hand. Now turn only the lower riser clockwise or counter-
clockwise until the nozzle arrow is pointing where you want the sprinkler
to begin spraying.
3CHANGING THE ARC
Insert the K-Key or a flat blade screwdriver into the
Arc Set Adjustment slot.Turn clockwise to increase
the arc or counter-clockwise to decrease the arc.
WHEN SET AT 360°,THE K2 SMART SET WILL ROTATE
CONTINUOUSLY IN A CLOCKWISE DIRECTION.

NOTE: The K2 Smart Set is factory preset with a 90° arc setting, and includes a pre-installed #2.5 nozzle.

SPRINKLER INSTALLATION
1INSTALL 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.
2INSPECTING 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
assembly and can easily be pulled out, cleaned and re-installed.
3WINTERIZATION TIPS
When using an air compressor to remove water from the system
please note the following:
1) Do not exceed 30 PSI.
2) Always introduce air into the system gradually to avoid air
pressure surges. Sudden release of compressed air into the
sprinkler can cause damage.
3) 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.
