How to use the S15 Sprayer
~ continued
Technical spray information and how to ensure accuracy
The S15 has an adjustable height nozzle that offers spray widths from approximately 3 feet/.9 meters to 5 feet / 1.5 meters.
Spray Width Adjustment
You can adjust the spray width of the S15, which will change the application coverage, by
moving the Adjustable DCV holder up or down. To use, loosen the knob located on the front
of the skirt, and slide the DCV & Nozzle assembly up/down to the desired spray width or to a
position indicated on the Application Chart on the previous page, then tighten knob. There
are indices molded into the DCV Holder for easy repeatability.
The S15 uses Teejet TF nozzles are designed
to “feather” at the edges to allow the second
pass to “feather in,” and so provide uniform
coverage. The area of “feather” or overlap,
is approximately 15% of the spray width at
the edges, for a total of 30% over the two
edges/ends of the spray pattern. To maximize
uniform coverage the next pass should overlap
the prior to allow for the 15% “feather” or
overlap.
Ensure accuracy
It is important that the S15 sprayer has a minimum of 1-gallon/4-litres
of liquid in the tank at all time, and is pushed in a manner that keeps the
spray head parallel to the ground at all times, so that the spray nozzle
is constantly kept at the same correct height. Keeping the height of the
nozzle constantly parallel to the ground ensures the nozzle will spray to its
stipulated spray application cover. If the sprayer is pushed at a downward
angle and the nozzle tip is nearer to the ground, the spray width will be
reduced and over application will occur. In the reverse situation of the
spray nozzle height being increased by pushing the sprayer at an upward
angle the nozzle fan will be wider, the spray width will become
inaccurate, and under application will likely occur. To ensure spray
width accuracy it is important that the operator is aware that the
sprayer is pushed in a manner that keeps the nozzle constantly
parallel with the ground.
To aid accuracy use a proprietary spray dye indicator which allows
the operator to see where they have sprayed. Contact your local
landscape supplier for a recommendation.
After use
1.
Empty any unused contents out of the spray tank. The S15 tank has been designed to easily empty and clean. Dispose of the tank
contents and all washings in accordance with the manufacturer’s disposal instructions on the product that has been used.
2. Wash out the tank thoroughly using clean water and or a preparatory tank cleaner. Make sure that the nozzle and spray gun (if included)
are thoroughly washed as well. To wash through the pipework to the spray nozzle, add an additional 1/2 gallon/2 liters of clean water to
the tank and wash this through the nozzle by pushing the sprayer over a safe area for the purpose of disposal of washings.
3. Empty all water out of the sprayer making sure no water is left in the pump over winter - do not allow to freeze, unless you have setup
the S15 to operate in freezing temperatures using an Ice Melt or snow pre-treatment materials.

are required a cross pattern as shown
