how to adjust the fixed left stop on a Rainbird 5000

[sweaterfan]

Hi,

I recently bought a house that has Rainbird 5000 sprinkler heads and one of the sprinklers was obviously improperly installed, soaking the kitchen windows. The left stop needs to be adjusted, but is fixed on the 5000. The Rainbird instructions say I can "unscrew the cap and pull out the assembly..." but I'm not sure what they mean by this. Is there a screw on the top that holds down the cap, or do I have to dig around the head a little to expose the case and twist the top of the body?

Or is there a better solution?

Thanks.

Mike

One step behind casey!
Installing and Removing Nozzles:
1. Insert tool into pull-up slot, turn 90 degrees, and lift up stem. (A)
2. Insert the desired nozzle into the nozzle socket, and turn the radius
adjustment screw clockwise to secure the nozzle in place. (B)
3. Insert the selected nozzle’s identification plug into the opening on
the top of the rotor.
4. To remove the nozzle, back out the radius adjustment screw,
place the blade of the screwdriver under the nozzle removal tab
and press the handle down. (C)
Setting the Arc:
The arc is adjustable from 40 –360 degrees (PC units only). The rotor
is factory set to 180 degrees.
Align Fixed LEFT Edge:
1. Pull up turret and turn to the left trip point (counterclockwise).
CAUTION: If the rotor does not turn easily to the left, first turn it
right (clockwise) to the right trip point.
2. Rotate entire case to the desired fixed left position, OR unscrew
cap and pull out assembly. Rotate internals to re-align left trip
point to the desired point and re-install.
To increase or decrease the arc: (D)
1. While holding the nozzle turret at the fixed LEFT stop, insert tool
or screwdriver into the adjustment socket.
2a. Turn the screwdriver clockwise, (+) to INCREASE arc.
2b. Turn the screwdriver counterclockwise, (-) to DECREASE arc.
3. Each full clockwise turn of the screwdriver will add or remove 90
degrees of arc.
4. When the maximum arc of 360 degrees or minimum arc of 40
