Mini 8, Gear Driven Sprinkler
User’s Guide
The Mini 8 rotor arc is pre-set at the factory.
The screen can be accessed through the
bottom of the riser. Remove the cap of the
Mini 8 and lift the riser assembly out of the
housing cannister. If plugged, the screen can
be removed, cleaned, and re-inserted into
the riser.
The Mini 8 rotor has a fixed LEFT stop. To find the left stop position,
rotate the nozzle turret clockwise (to the right) until it stops, then rotate the
nozzle turret all the way back to the left.
The Mini 8 rotor is designed for residential and light commercial
installations. It comes in three sizes, 4" pop up, 6" pop up and 12" pop up.
To increase the arc, insert the key into the arc adjuster shown in Figure 6.
Hold the turret in place while turning the tool clockwise. Keep turning until
the arc indicator arrow points to the desired arc angle.
Screen
Nozzling Up The System
The 1.5 GPM nozzle comes pre-installed from the factory. A nozzle tree
consisting of four additional nozzles is provided with each rotor (Figure 1).
Please see the nozzle performance chart for flow rates. By using various
combinations of nozzle flow rates, you can balance the sprinklers to
achieve approximately the same precipitation rates.
As an example indicated in Figure 7, the arc is set to 270˚. The sprinkler
will then water from the left stop and rotate clockwise (see Figure 8) until
270˚, the adjusted right stop, is reached. The sprinkler will then return back
to the left stop and repeat the cycle.
Mini 8 Nozzle Performance
Every case of Mini 8 product contains two Mini 8 rotor keys. The Mini 8 key
is used to pull up the riser, to remove the nozzle, to reduce the radius and
to adjust the arc (Figure 2).
To decrease the arc, insert the key into the arc adjuster. Hold the turret in
place while turning the tool counter clockwise. Keep turning until the arrow
points to the desired arc.

To line up the left stop with landscape features which define the left side of
the irrigated arc, simply turn the housing cannister and point the left stop
towards the desired direction. You may also pull the riser up with the key
and rotate the LOWER portion of the riser until the left stop is at the
desired position. DO NOT rotate the TOP portion of the riser.
