and only enough to support the swing joint and rotor in this initial
setting. Back-filling the gravel during this phase will also serve to
help support the enclosure's sidewalls during the heavy equipment
compaction process of the surrounding surface.

Setting the rotor to final Grade

With the rotor held within the enclosure's cover, check to see if the
swing joint needs adjustments in order to achieve a rotor grade
that is level to the enclosure cover. If so, remove/add gravel as
necessary to achieve desired grade. Continue back-filling and
packing the material. Finished level of the back-fill is to be at the
same level as the bottom of the rotor's compartment (approx. 5"
from the underside of the enclosure's cover. Check to see if the
rotor will remain in position if released. If not, pack more back-fill
material beneath the rotor.
Next, carefully lift and remove the cover from around the rotor. Now
stake and band the rotor per specifications taking care not to move
rotor's position. Once complete, replace cover to confirm that rotor
remains to grade. If not, adjust.
noTE: Care needs to be taken to ensure the
rebar stake does not penetrate subsurface
piping or irrigation mainline.

Setting rotor's arc orientation and arc adjustment

In order to position the rotor such that it will apply water in the
intended area, the arc orientation (direction) and the adjustable
arc must be set. These initial adjustments can be made without
10
water running through the rotor. The first step is to remove the
riser assembly so that the right fixed stop of the arc adjustment
mechanism can be aligned to the right side of the area to be
irrigated. In order to remove the riser assembly, the upper
snap-ring must be removed from the rotor.
Upper Snap-Ring Removal
Prior to removal of the upper snap-ring assembly, the rubberized logo
cap must be removed and the riser assembly must be pressed below
the snap-ring's rubberized seal. If the procedure below is not followed,
the upper snap-ring assembly cannot be removed from the rotor.
Remove the stainless screw from the center of the rubberized logo cap
using a Phillips screwdriver (fig 1). Prior to removing the rubberized
logo cap, note that the arrows on the logo indicate the position of the
nozzles on the riser assembly. As the rubberized logo cap is removed,
note there is a protruding pin on the underside of the logo cap (fig 2).
This pin is the alignment feature on the rubberized logo cap that must
be inserted correctly during assembly in order for the arrows on the
rubberized logo cap to be positioned over the nozzles below. Note
which hole the pin fits into on top of the riser (fig 3).

Once the rubberized logo cap is removed, use the heal on the palm
of your hand to forcefully press the riser assembly down (fig 4) and
below the rubberized wiper seal on the snap-ring assembly (fig 5).
