Inspection & Setup
Inspection & Setup
Your Wylie Power Sprayer was manufactured to the highest standards of quality. It is necessary though, to check
to make sure that nothing was damaged during shipping.
Check bolts and fasteners for tightness, especially lug nuts.
Check the pump and plumbing for any signs of damage.
Do not add any chemical to the spray tank until the
sprayer has been checked for proper operation. Failure to do so could result in chemical exposure.
Your Wylie Poultry House sprayer was completely assembled at the factory and should not need any additional
assembly before use.
Preparing Sprayer for Operation
Add about 50 gallons of water to the spray tank. Do not
add any chemical until the sprayer has been checked for
proper operation.
Attaching Sprayer to Tractor
Pin the hitch to the drawbar of the tractor. The elliptical tank
sprayer has a height adjustable hitch. Set the hitch so that
the trailer is level when attached to the tractor.

Operation
The DP-392 pump operates at a maximum pressure of 725
PSI. The handgun can operate at a high pressure, but the
boom should operate at no more than 60 psi. To increase
the handgun pressure, loosen the jam nut on the pressure
adjustment knob. The bypass valve can be open or closed,
but it may be easier to adjust with the bypass valve open.
Rotate the pressure adjustment knob clockwise (tighten)
to increase pressure.
Never point the trigger gun at any part of your
body. The high fluid pressure and/or chemical
exposure could cause serious bodily injury.
Operating Recommendations
Be aware of any obstructions, animals or people while
spraying. While the boom is equipped with a breakaway
to help protect the boom, damage or injury can occur
in a collision.
< Bypass

Maintenance
Maintenance
Line Strainer Cleaning
In order to clean the boom nozzles, remove the nozzle
from the stand. Use compressed air to blow debris from the
nozzle. Do not use pocket knives, wire or screwdrivers.
From time to time it may be necessary to clean the line
strainer. The line strainer is located in the hose between the
spray tank and the pump. With the tractor turned off, close
the ball valve beside the strainer. Unscrew the bowl from
the strainer base. Remove and clean the screen. Check for
any damage to the screen that would allow debris to get to
the pump and nozzles. Empty and rinse the bowl. Replace
the bowl and screen. Make sure that the gasket/o-ring that
seals the bowl to the base is not lost when cleaning. Open
the ball valve before starting the pump.
End of Day Procedure
Some disinfectants can be corrosive to the pump if allowed
to remain in thepump for extended periods of time. It is
best to flush the pump with clean water to prevent pump
damage. Add 5-10 gallons of clean water to an empty
spray tank. Turn the pump on and apply this flush solution
to a safe area.
Check the sprayer for any leaks or damaged parts. Repair
or replace as necessary.
Operation during cold weather may require protecting
the sprayer from freeze damage. See the next section for
instructions.
Chemically resistant rubber gloves must be worn
when cleaning the line strainer. Failure to do so
could result in chemical exposure
causing serious injury.
End of Season Procedure
Thoroughly flush the complete system with clean water.
Flush the trigger gun as well as the boom nozzles. Dispose
of the flush solution by spraying a safe area. Check the
chemical container label for any special instructions.

To protect the sprayer from freezing, one of two procedures
should be followed: draining the system or flushing with
anti-freeze solution.
O-Ring >
Draining the sprayer
With the spray tank empty, remove the strainer bowl to drain
water from the suction side of the pump. Open the bypass
valve so that the pressure drops to zero, then let the pump
run without liquids for two minutes. Lay the trigger hose out
flat, open the control valve, lock the trigger gun open and
allow the water to drain from the gun. Open other lines to
allow any water to drain.
< Screen
Strainer Bowl >
Figure C1
Cleaning Line Strainer
Cleaning Nozzles
Flushing with anti-freeze
Add a few gallons of anti-freeze solution (such as camper
trailer anti-freeze) to the spray tank. Open the valves and
start the pump to flush both the trigger gun and boom
nozzles. This procedure is the most complete way to protect the sprayer from freezing. Empty the pump as per the
instructions above.
While the line strainer usually keeps the system clean,
it is possible for foreign matter to clog the trigger gun or
boom nozzles.
Turn the tractor off before cleaning any nozzles. Wear
chemically resistant rubber gloves.
To clean the trigger gun nozzle, engage the trigger gun to
relieve any pressure. Remove the cap at the end of the barrel to access the tip. The tip should be cleaned with a brush
such as a TeeJet tip cleaning brush. Do not use a pocket
knife, wire or screwdriver to clear the nozzle. The tip could
be damaged, resulting in an improper spray pattern.
