Technical spray information and how to ensure accuracy
The S25 SPRAY-PRO Mark III has an adjustable height nozzle that offers a spray width
from approximately 3 feet/.9 meters to 5 feet / 1.5 meters.
Spray Width Adjustment
You can adjust the spray width of the S25, 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.
The SPRAY-PRO 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 second pass over the area
should allow for the 15% “feather” or overlap.
Ensure accuracy
It is important that the S25 SPRAY-PRO sprayer 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 becoming inaccurate,
under application will likely occur. To ensure spray width accuracy it is important that
the handlebar height is set right for the individual user, and the operator is aware that the
sprayer is pushed in a manner that keeps the nozzle constantly parallel with the ground.
Keeping the top of the tank parallel with the ground is a good guide.
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 S25 SPRAY-PRO 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 or 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 S25 to operate
in freezing temperatures using an Ice Melt or snow pre-treatments.
Maintain the wheel knurled pins regularly by cleaning any debris or dirt
from the Drive Wheel axle area. Keep knurled pins well lubricated to
prevent seizure. An Extra set is included!

Most applications will only require

should be used.
