Assembly Instructions
Remove all parts from the box. Open the parts box and parts
bag. Find the two horizontal mounts (5277930 and
5277931). Position the boom brackets and fasten the
horizontal mounts (weld nuts facing up) and boom brackets
(5277933) to the sides of the frame using four 3/8” x ¾”
screws (5034660). Attach the boom mounts (5095332) to
the boom brackets with four 5/16” x ¾” screws (5117323)
and 5/16” nuts (5006307). Mount the boom using the U-bolts
and remaining 5/16” nuts. Position the nozzles on the boom
and attach the boom feeder hose with the hose clamp. Using
four more 3/8” screws, attach the upright tubes (5277927 and
5277928) to the sides of the frame. Start four more 3/8”
screws into the horizontal mounts, position the 90 degree
upright tubes (5100775) and tighten the screws. Start two
3/8” screws into the weld nuts on each of the slide tubes and
slip the slide tubes over the upright tubes. Attach each of the
lock and ride plunger mounts to the four slide tubes using
3/8” screws and nuts. Using the lock and ride plugs
(5102133) and anchor plates (5027426), secure the sprayer
to the ATV. Check that all screws are tightened. Screw the
gauge into the gauge tee on top of the valve mount using a
9/16” wrench. Check that the drain plug cap is screwed on
securely. Plug the lead wire (5274443) into the plug off the
pump and hook to a 12 volt battery source. Note: there is a
switch on the pump and a switch on the lead wire.
Tools Needed
A ½” wrench and socket, a 9/16” wrench and socket, pliers,
Phillips screw driver and pipe sealant for the gauge.
(1) Unit assembly, (1) boom, (2) boom brackets (5277933),
(2) boom mounts (5095332), (1) parts box with parts bag.

Operation & Calibration
The performance of any agricultural chemical depends upon
the proper application of the correct amount.
Be sure that your equipment has been calibrated before
spraying.
Initially begin spraying by opening the handgun. This will
enable the air in the line to be eliminated through the tip, while
building pressure.
The pumping system draws solution from the tank, through
the strainer, and to the pump. The pump forces the solution
under pressure to the handgun or boom nozzles.
Pressure may be decreased by opening the bypass valve
to the tank. When it is closed the highest spraying pressure
will be reached.
• Open the handgun by squeezing the handle lever
• Rotating the adjustable nozzle tip on the handgun will
change the tip from a straight stream to a cone pattern (finer
mist). Be sure the thumb nut on the adjustment nozzle is
tight.
• The pump motor's demand switch shuts off the motor when the
handgun, bypass valve and boom lines are fully closed.
The system remains pressurized, and the pump motor will
restart automatically when the handgun or boom line is
opened. If, however, the bypass line is open, the pump will
not shut off automatically.
• The 3 nozzles are fixed on 17 1/2" spacing.
• All three nozzles spraying at the same time will allow a
maximum coverage of 30 ft. Overlapping of the ends of the
spray pattern will not be needed.
• The center nozzle will cover a 80" swath.
• Each of the three nozzles has a means of shutting down, so
you may choose the coverage that is needed.
Adjusting Pressure
- When the bypass valve is closed, pressure is at the highest point.
- Opening the valve will decrease pressure.
Testing the Sprayer
It is important to test the sprayer with plain water before
actual spraying is attempted. This will enable you to check the
sprayer for leaks in the plumbing system.
1. Open tank lid and be sure the tank is clean and free of foreign
material. Fill the tank about half full with plain
water.
2. Open the valve on the filter/valve assembly next to the pump
and allow water to flow to the pump. The valve is located at this
point to enable the strainer to be taken apart for cleaning.
3. There are two valves located on the valve and handgun bracket.
One of these is a shut-off for the boom and the other is for
pressure adjustment. Open the valve that controls flow to the
boom and open the bypass control valve.
4. You may now start the sprayer.
5. The pressure should now be increased to as desired by closing
the bypass valve.
6. During this testing period be sure to observe the spray pattern
given by the spray nozzles. Each nozzle should overlap the next
nozzle approximately 30%. If there is any pattern distortion, it will
be necessary to remove and clean the affected tips.
CAUTION: Never use a metal object or other sharp item
for cleaning a nozzle tip. It is better to use a nozzle brush
(not wire brush) or compressed air for tip cleaning.
Drain all water out of your sprayer, paying special attention to
the pump, handgun, and valve(s). These items are especially
prone to damage from chemicals and freezing weather.
The sprayer should be winterized before storage by pumping a
solution of RV antifreeze through the entire plumbing system.
This antifreeze solution should remain in the plumbing system
during the winter months. When spring time comes and you are
preparing your sprayer for the spray season, rinse the entire
plumbing system out, clearing the lines of the antifreeze
solution. Proper care and maintenance will prolong the life of
your sprayer.
Winter Storage
Using the Boom Nozzles
Four things must be considered before spraying with the boom:
How much chemical must be mixed in the tank. 1.
Rate of spray (gallons per acre to be sprayed) 2.
What pressure (p.s.i.) will be used. 3.
Speed traveled (mph) while spraying. 4.
- Refer to the chemical label to determine your chemical mixture.
- See the tip chart to determine the pressure to be used. The
chart will also show the speed used when spraying.
- Start the pump and open the valve(s) to the boom nozzles.
- Check the spray pattern. Usually you can see the coverage
better on a solid concrete surface, such as a driveway.
- The boomless nozzles should be approx. 33" above the objects
being sprayed.
After Spraying
After use, fill the sprayer tank part way with water. Start the
sprayer, and allow the clear water to be pumped through the
plumbing system and out through the spray nozzles.
Refill the tank about half full with plain water and use a common
tank neutralizer and cleaner, and repeat cleaning instructions
above.
Flush the entire sprayer with the neutralizing/cleaning agent, then
flush out one more time with plain water. Follow the chemical
manufacturer's disposal instructions of all wash or rinsing water.
For the boom, (if applicable) remove the tips and screens from the
nozzle assemblies. Wash these items out thoroughly. Blow the
orifice clean and dry. If the orifice remains clogged, clean it with a
fine bristle (NOT WIRE) brush, or with a toothpick. Do not damage
the orifice. Water rinse and dry the tips before storing.
WARNING: Some chemicals will damage the pump valves if
allowed to soak untreated for a length of time! ALWAYS flush
the pump as instructed after each use.

nozzles from overlapping with the center nozzle.
