Instructions / Assembly

NOTE: The K2Pro is factory preset with a 90° arc setting, and includes a pre-installed #2.5 nozzle.
CHANGING A NOZZLE
1. REMOVING THE NOZZLE RETENTION SCREW
Use your K-Key (A) or a small flat blade screwdriver to remove the nozzle retention screw (B) by turning
counter-clockwise to remove and clockwise to re-install.
2. PULL UP THE RISER
Insert the K-Key (A) in the keyhole (F) 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 (F) when you pull it up. Firmly pull up the entire spring-loaded
riser (L) to access the nozzle socket (H). Hold the riser assembly up with one hand.
3. REMOVING THE NOZZLE
With the nozzle retention screw (B) removed, insert the K-Key (A) into the slot directly under the nozzle
prongs (G) at the top of the nozzle. Now, turn the key 1/4 turn to “hook” the nozzle and pull the nozzle out.
4. INSTALLING A NOZZLE
Press the desired nozzle into the nozzle socket (H). Make sure the nozzle number is visible and the nozzle
prongs (G) are up. Then, re-install the nozzle retention screw (B). NOTE: The nozzle retention screw (B) is
also a break-up screw should you wish to reduce the spray distance but NOT the flow.
SETTING ARC ADJUSTMENT
1. FINDING THE LEFT START POSITION
Place your finger on the top center of the nozzle turret (K). 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 (C). This is the “Left Start”
position (M). The sprinkler will begin spraying from this position and rotate clockwise until it reaches the
right Adjustable Stop (N).
2. CHANGING THE LEFT START POSITION
Insert the K-Key (A) in the keyhole (F) on the top of the nozzle turret (K) and turn the key 1/4 turn to insure
that the key does not slip out of the keyhole (F) when you pull it up. Being careful not to allow the nozzle
turret (K) to turn, firmly pull up the entire spring-loaded riser. Hold the lower riser (L) assembly up with
one hand. Now turn only the lower riser (L) clockwise or counter-clockwise until the nozzle arrow (C) is
pointing where you want the sprinkler to begin spraying.
3. CHANGING THE RIGHT STOP POSITION
Insert the K-Key (A) or a small flat blade screwdriver into the arc set adjustment (O). Turn clockwise to
increase the arc or counter-clockwise to decrease the arc. NOTE: The arc set arrow (E) in the center
of the nozzle turret (K) rotates to show the current setting. When set at 360°, the K2PRO will rotate
continuously in a clockwise direction.
4. OPERATING THE DISTANCE & FLOW CONTROL
To adjust water flow & distance insert your K-Key (A) into the Distance & Flow Control (D) and turn
counter-clockwise. During zone operation the Riser (L) will remain up.
