Hi, I'm Brad with Orbit.
Today, we're going to talk about how to adjust
your Saturn IV gear drive.
The Saturn IV is new in the line up of gear
drives by Orbit.
It's similar to the Saturn III but it uses
a key instead of a screwdriver adjustment.
All you'll need for this procedure is your
adjustment key.
Let's go ahead and get started now.
Here, we have a Saturn IV that's already been
installed in the ground.
The first thing you'll want to check is the
rotation of the arc on top of the head.
The arrow on top indicates the direction of
the spray.
First thing you'll want to do is turn the
turret or the green top all the way to the
left to clear it.
Turn it back to the right to indicate your
right stop.
The right stop is a fixed position.
To adjust the right stop, you'll want to loosen
the top of the head from the canister by turning
the collar like this.
Remove that from the canister.
You can see the teeth on the bottom of the
head.
It will keep it in place once it's put back
in.
We'll set this so that the arrow goes down
the right side of our area to be watered.
As you can see on this sidewalk is the right
edge of our area.
The sidewalk is also our left edge.
We'll twist the turret to check the adjustment
of our spray.
You can see that it's not going far enough.
At this point, we'll use the key to make further
adjustments.
To make pattern adjustments on the head, simply
insert the plastic end of the key into the
plus or minus slot indicated on top.
With the key in place, you can now make your
adjustments.
All adjustments you make, you're going to
want to do in the right stop position.
Again, you can turn the turret to the left
and then back to the right.
This is where you'll want to make your adjustments.
In this case, we need to increase the arc
so we'll turn the key clockwise.
One full turn of the key equals 90 degrees.
You can see, we need to go just at little
bit further.
If you need to make further adjustments, again,
repeat the same procedure by turning the head
back to the right stop position and then turning
the key.
There, our adjustment is complete.
You can leave the key in the head during the
adjustment but make sure to remove the key
before you activate your sprinklers.
After you've adjusted the spray pattern of
your head, you can now adjust the spray distance.
Using the defuser screw located under the
arrow we indicated earlier, you can decrease
or increase the spray coming out of the head.
In this case, we'll turn the key clockwise
to decrease the spray distance using the defuser
screw.
You can also loosen the screw to increase
the distance.
One thing you'll want to make sure not to
do is back the screw up too far as that's
what holds the nozzle in.
After you�ve set your distance, your head
is ready to go.
