Inspection & Setup
Inspection & Setup
3 Point Carrier & Boom:
The 8420 boom and VSB can be mounted on the tractor
3 point hitch with or without a tank. If the boom is not
equipped with a tank, the tractor must be equipped with
front or side mount tanks to supply the boom with spray
solution.
The boom should be delivered setup and ready to mount
to the tractor without further assembly.
Crushing Hazard
To prevent serious injury or death:
Do not stand between sprayer and moving tractor
Stop tractor engine and set brake before installing pins
Mounting 3 pt. Carrier/Boom
Mount the carrier to the tractor 3 point hitch. Connect the
boom hydraulic and pump hydraulic hoses (if equipped)
to tractor hydraulic circuits. Adjust the top link to level the
sprayer when the boom is at spraying height. Move the
tractor to a at area with su󰀩cient clearance to unfold the
boom.
Spray Trailer & Boom:
The sprayer should be delivered setup and ready to attach
to the tractor without further assembly.
Attach to the tractor drawbar. Make sure that the clip pin is
inserted in the pull pin to prevent the pull pin from coming
out while transporting or spraying. The elliptical tank
sprayer has a height adjustable hitch. Set the hitch so that
the trailer is level when attached to the tractor.
A jack transport mount is available on some trailers which
prevents damage to the jack in very short turns.

Connect the boom hydraulic hoses and pump hydraulic
hoses (if equipped) to the tractor remotes. Hydraulic
centrifugal pumps require a tractor hydraulic circuit. Most
8420 booms are equipped with hydraulic fold while VSB
and 8220 booms are manual fold. The 8420 booms are
equipped with a parallel linkage and require a hydraulic
circuit. VSB and 8220’s bolt directly to the trailer frame.
The tractor engine should be shut o before
attaching the pump to the PTO shaft. Failure to do so
possibly cause serious injury or death.
Roller pumps are powered by the tractor PTO. The pump
may be equipped with a PTO drive shaft or the pump may
couple directly to the tractor PTO shaft.
Direct coupled roller pumps must have the chain attached
to the tractor frame to prevent the pump from rotating when
the PTO is engaged.
Spray Controller:
Several sprayer controllers can be tted with the 8420 boom
and the VSB’s. Usually the 8420 is controlled by the Raven
450 automatic controller or the Remcor 2551 controller. The
VSB and 8220 booms are usually controlled by a Remcor
2040 electric controller or the Hypro manual controller. If your
sprayer is equipped with a Raven or Remcor controller, refer
to the appropriate manual for detailed instructions on setting
the controller up for operation. The console should be mounted
in a convenient location in the tractor cab for easy access.
If your sprayer is equipped with a Hypro manual controller,
no further installation should be required.
Once the controller, foam marker control and any other
accessories are installed, move the tractor to a at area
with su󰀩cient clearance to unfold the boom.
Boom Inspection & Setup:
8420 Boom
The 8420 boom is equipped with an “over-center” break-
away that protects the boom when an obstruction is struck.
The breakaway may be folded to make transport easier.
If so, the breakaway must be unfolded manually.
Assure that the area is clear of all people before
unfolding boom. Failure to do so could cause bodily
injury to anyone hit by an unfolding boom.
Engage the hydraulic lever to unfold the boom. Carefully
unfold and fold the boom several times to purge any air
from the folding hydraulic system.
With the boom unfolded, check along the length of the
boom to assure that the boom is straight. If one or more
sections of the boom is not straight, refer to page 17 for
instructions on how to straighten boom.

cables to make sure that they have uniform tension when
the boom is unfolded.
8220 Boom
The 8220 boom is a manually folded boom. Remove the
pin from the transport lock and rotate the boom to the spray
position.
Flushing The System
Do not add any chemical to any tank until the sprayer
has been fully checked for leaks.
Load about 100 gallons of clean water into the spray tank.
Add a few gallons of water to any other tanks such as the
fresh water tank.
Open ball valves to allow water to gravity ow through the
system. Check for any leaks. Close all ball valves except
the main ball valve between the spray tank and the pump.
Any uid leak on the suction side of the pump will result in
an air leak when the pump is started.
It is important to ush the boom before installing the spray
tips.
The sprayer can be equipped with a variety of pumps. The
following section will help starting the sprayer with the most
popular pumps.
Centrifugal Pump (Hydraulic Drive)
Note: The hydraulic uid ow supplying the pump must be set
the rst time the pump is engaged and anytime a dierent hy-
draulic circuit or tractor is used. Before engaging the pump, turn
the hydraulic adjustment to its lowest setting for that particular
circuit. With the return and boom valves turned o, engage the
hydraulic lever and slowly increase the hydraulic uid ow until
the boom pressure gauge reads no more than 100 psi.
Inspection & Setup
VSB (Vari-Space Boom)
Do not let the VSB drop. Allowing the boom to
free-fall into spray position could cause bodily
injury to anyone struck by a falling boom.
The VSB is a manual fold boom. The length of the boom
will determine if it is equipped with a secondary section.
With the sprayer positioned in an open area, remove the
lock pin while holding the boom. Let the boom lower into
position.
Once the boom has been lowered, unfold the secondary
section (if equipped). It is important to ush the boom
before installing the spray tips. Check the suspension

Preparing The Sprayer For Operation
Install the spray tips and tip screens in each nozzle
body.
Open the agitator ball valve on the spray tank. Engage
the pump and open the valves to bring the boom up to
operating pressure. With the boom spraying, check all
plumbing connections for leaks. Make sure that all tips
are spraying a uniform pattern.
If the Hypro manual control is used, the operating pres-
sure will have to be set. The operating pressure is set by
adjusting the pressure relief valve located on the top of the
Hypro control valve. With the boom valves closed, tighten
the pressure relief valve to increase the pressure.
Figure A14
Installing tip screen and spray tip
Inspection & Setup
Activate the switch for each boom section to open the boom
valves (automatic controller should be set to “manual”) and
ush the boom with clear water. Turn the pump o󰀨 once
the boom is ushed.
Roller Pump (PTO Drive)
With the agitator line open, engage the PTO drive to start
the pump. Water should be returning to the tank through
the agitator and the return line.
If an electric controller is used, turn the boom switches on
to allow water to ow through the open nozzle bodies. Turn
the pump o󰀨 when the boom has been ushed.
If the manual Hypro controller is used, ip the boom valves
up to open the valves and allow the water to ow through
the open nozzle bodies. Close the valves and turn o󰀨 the
pump when the boom has been ushed.

Operation
Loading Spray Material Into The
Sprayer
Spraying solution can be loaded by either lling with a
pre-mixed solution or mixing the chemical and carrier on
the sprayer. Most trailer mounted sprayers have a Mix n’
Fill tank mounted on the trailer while most 3 point sprayers
use the Mix n’ Fill tank on the nurse trailer.
Always wear protective clothing, i.e. apron, face
shield, gloves and respirator, when handling any
chemicals. Failure to do so will risk chemical expo-
sure to your body resulting in sickness, injury or
possibly death.
3 Point Carrier:
3 point carriers may be equipped with an optional “Quick
Fill”. Remove the cap from the spray tank “Quick Fill”
coupling and attach the supply hose to the coupling. Open
the “Quick Fill” ball valve as well as the supply line. Fill
the spray tank with water or mixed solution.
If you are mixing the chemical in the spray tank, carefully
add the desired amount of chemical to the spray tank.
Turn the pump on and allow the agitator to circulate the
chemical for several minutes.
Trailer Sprayers:
Remove the cap from the “Quick Fill” coupling on the Main
Fill valve and attach the supply hose to the coupling. Open
the main ll ball valve as well as the main tank ball valve.
Make sure that the Mix-n-Fill valve is closed. Open the
supply line. Fill the spray tank with water, less the amount
of chemical to be added. (The Ace pump can be used to
ll the tank by closing the main valve and opening the ller
and return valve.)
The EP-1000 spray trailer is equipped with a Mix-n-Fill
tank mounted in the trailer tongue while the HCS-500T
spray trailer has the Mix-n-Fill tank mounted on a parallel
linkage frame.
EP-1000 Trailer Mix-n-Fill:
With the Mix-n-Fill valve closed, add the desired amount
of chemical to the Mix-n-Fill tank.
Open the agitator and return lines, then engage the pump.
Close the spray tank ball valve about halfway to “starve”
the pump slightly. Open the Mix n’ Fill ball valve to allow
the chemical to be drawn into the pump. Close the Mix
n’ Fill ball valve once the tank is empty to prevent an air
leak on the suction side of the pump. With the return ball
valve open, let the pump circulate the solution for several
minutes. Rinse the Mix n’ Fill tank and draw the rinse water
into the spray tank.

With the Mix n’ Fill ball valve closed, add the desired
amount of chemical to the Mix n’ Fill tank. Open the agitator
and return lines, then engage the pump. Close the spray
tank ball valve about halfway to “starve” the pump slightly.
Operation
HCS-500T Trailer Mix-n-Fill:
Pull the lock pin and lower the Mix-n-Fill tank. Place lock
pin back in the frame so that the tank stops in the correct
horizontal position. Assure that the Mix-n-Fill ball valve
is closed.
The Mix n’ Fill tank should always be empty except
when adding chemical to the sprayer. Raising and low-
ering the tank with chemical is dangerous and greatly
increases the possibility of chemical exposure to your
body resulting in sickness, injury or possibly death.

Operation
Open the Mix n’ Fill ball valve to allow the chemical to be
drawn into the pump. Close the Mix n’ Fill ball valve once
the tank is empty to prevent an air leak on the suction side
of the pump.
With the return ball valve open, let the pump circulate the
solution for several minutes. Rinse the Mix n’ Fill tank and
draw the rinse water into the spray tank. Raise and lock the
Mix n’ Fill tank in the transport position. Close the return
line ball valve before starting to spray.
Other Spray Trailers:
Add chemical to other spray trailers by pouring the desired
amount of chemical in the spray tank through the llwell.
Open the spray tank valve and the agitator valve. Start the
pump and mix the chemical thoroughly.
Operating The Sprayer
The 8420 boom is equipped with lock bars to prevent
boom movement during transport. The lock bars should
be lowered before operation to allow the boom to self-level
during operation.
The boom must always operate perpendicular to the
ground. Failure to do this can cause excessive yaw
movement and can damage the boom.
Levelling Trailer Sprayers
Adjust the drawbar clevis on trailer units to level the spray
trailer. Set the boom to the desired spraying height by
adjusting the parallel linkage.
Levelling The Boom On 3 Point Units
Set the 3 point hitch on 3 point mounted units at the desired
boom spraying height. Adjust the top link to level the boom
while in the spraying position. (See Figure B13)
Activating The Sprayer
If you are using an automatic controller, refer to the owner’s
manual for instructions on setting the controller for the
desired spray volume and speed.

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.
Engage the pump, activate the master switch on the con-
troller and begin spraying.
The 8420, 8220 and VSB are designed to operate at speeds
of 5-10 mph. Care and common sense, however, must be
used to determine the optimum speed for a particular spray-
ing operation. Factors such as rough surface conditions,
hillsides and terraces will require a slower operating speed.
Listed below are several things you should check to main-
tain trouble free spraying:
*Make sure spray tips are sized for the desired volume
and speed. (Refer to the TeeJet Catalog or Wylie
Catalog website if using TeeJet™ tips.)
*Clean pump strainer as needed to maintain adequate
ow to the pump.
*Keep tractor hydraulic level full for consistent
pump operation.
*Keep the agitator ball valve open and the return line
ball valve (if equipped) closed or slightly open while
spraying.
End Of The Day Procedure
Some chemicals require the boom to be ushed at the
end of the day to prevent corrosion in the pump or settling
of chemical in other components. To ush the pump and
boom, close the main tank, agitator and return line ball
valves, then open the fresh water tank valve. Set the con-
troller for manual operation, engage the pump and open
the boom valves to allow fresh water to ush the pump
and boom.
Operation
(4) Remove tips and strainers from the nozzle bodies.
Clean strainers and check tips for wear and damage.
(5) Open controller ball valves. Allow the system to
drain completely to prevent any parts from breaking due to
freezing. Loosen at least one cap from each boom section
to allow any water inside the nozzle bodies to drain. Check
any ttings where water can collect and disconnect to allow
drainage. Reconnect all ttings and ensure tightness once
system is drained.
(6) For further protection, pump environmentally safe
antifreeze or winter grade windshield washing uid into
the lines.
Preparing The Sprayer For Storage
(1) Flush the tank, pump and lines with clean water.
(2) Remove cap from the “Quick-Fill” and open ball
valve.
(3) Remove the drain plug from the primary strainer and
the plug from the “Tee” to drain the tank and suction lines.
Remove pump plug to drain pump housing.

(2) Secondary strainers are located at each nozzle. To
clean, remove the nozzle cap (tip and gasket come out
with cap). Remove strainer from the nozzle body. Clean
and replace.
Wear chemical resistant rubber gloves,
apron and face protection when cleaning the
system. Failure to do so can cause sickness
or death. Read safety information provided
by chemical manufacturer for proper handling
procedures.
(1) Turn ball valve o󰀨. Remove the strainer’s base and
take out wire mesh screen. Clean and replace. Turn ball
valve on.
(3) Discard and replace damaged strainers.
It is possible for debris to get past the strainers and clog the
orice of the tip. Clean the tips with a TeeJet™ cleaning
brush only. Using wire, pocketknives or wire brushes
can cause damage to the tip, altering spray volume or
pattern.
