carton. Lay out all parts and hardware and identify
using the illustrations on pages 3 and 4.
TOOLS REQUIRED FOR ASSEMBLY
(2) 1/2" Wrenches
(1) Screwdriver
(1) Pliers
(1) Hammer
•
Assemble a hitch arm to the inside of a frame tube
underneath the tank. Use two 5/16" x 2" hex bolts and
5/16" nylock nuts as shown in figure 2. Do not tighten
yet. Repeat for other side.
•
•
Assemble the axle through the holes in the frame
tubes.You may need to slightly loosen the bolts in the
frame tubes to make the axle fit. Retighten the bolts
only enough to flatten the lockwashers. See figure 1.
Assemble a spacer, a 1/2" flat washer, a wheel and
another 1/2" flat washer onto the axle. Lightly tap a
palnut onto the end of the axle. Repeat on other end
of axle. See figure 1.

Assemble the boom bars to the boom mount bracket
using two 5/16" x 1-1/4" carriage bolts, tooth lock
washers (between the bar and bracket), 5/16" flat
washers and knobs. The boom connecting hose
should extend upward. See figure 6.
•
•
At this time tighten all bolts starting with the bolts in
figure 2, then the bolts in figure 3.
Install the drain in the rear of the tank as shown in
figure 4. Place a 3/4" garden hose gasket onto the
drain body and insert the drain body out through the
hole in rear of the tank. Outside the tank, assemble
the nylon washer and then the nylon nut onto the
drain body. Tighten the nut securely enough to prevent
leaking, being careful not to damage the plastic parts.
Place the O-ring inside the nylon cap and screw the
cap onto the end of the drain body.
NOTE: Make sure the nozzle openings face straight
down when the boom bars are in the horizontal operating
position.

OPERATION
KNOWYOUR SPRAYER
Read this owner's manual and safety rules before operating your sprayer.
Compare the illustration below with your sprayer to familiarize yourself with the various controls and their locations.
ON-OFF SWITCH
BOOM ARM
ON-OFF VALVE
SPRAY GUN
ON-OFF SWITCH Turns pump/motor on or off.
ON-OFF VALVE Turns the flow on or off from the pump
to the boom nozzles.
out to obtain proper nozzle positioning.
SPRAY GUN Unhooks from tank for spraying shrubs,
small trees or areas inaccessible to the towed sprayer.
BOOM ARM Swivels up and down and adjusts in and
BEFORE STARTING
ADJUSTING SPRAY GUN NOZZLE
It is important to test the boom and spray gun with
plain water before attempting actual spraying. This will
enable you to check the sprayer for leaks and to set the
spray pattern and nozzle pressure. If a leak should occur,
thread tape may be used to better seal the fitting.
Turn the nozzle on the spray gun to adjust the spray from
a cone shaped fine mist to a straight stream. Maximum
gun pressure is attained with the ON-OFF valve shut off.
SETTING THE BOOM FOR SPRAYING
The correct positioning of the boom places the nozzles
approximately 40" apart and 14" above the ground. This
gives a spray width of approximately 80" with a slight
center overlap. See figure 11.
PUMP PRESSURE SWITCH
The pump is equipped with a pressure switch. The
pressure switch senses outlet pressure of the pump
and will turn off the electrical power to the pump at a
predetermined high pressure point (35 PSI). If the flow
demand is very low, the pump may reach this high
pressure point and the switch will cause "cycling" (the
pump cycles on and off rapidly). This is not a problem
unless the pump is subject to continuous cycling within
one second intervals for long periods of time.
a. Slide the boom bars out to the ends of the slots.
b. Swivel the boom bars until the nozzles are
approximately 14" above the ground.
c. Make sure the nozzles are adjusted so that the
openings point straight down.
40"
ON-OFF ADJUSTMENT OF BOOM NOZZLES
The sprayer is equipped with an "On-Off" valve for the
boom which allows the flow to the boom nozzles to be
shut off.

HOW TO USEYOUR SPRAYER
•
•
•
Drive to the starting place for spraying.
Set the boom in position for spraying.
•
Determine the approximate square footage of the
area to be sprayed. Use this amount to estimate
the number of gallons that will be required, based
on product recommendations. This can help avoid
unneeded solution left in the tank.
Set the throttle at the position determined in the 4th
step. Reach back and flip the pump/motor switch to
the "ON" position to start spraying.
Stay clear of flowers, shrubs and evergreen trees
when spraying weed control solutions to prevent
contact of the solution with these sensitive plants.
•
•
Determine the application rate (gallons per 1,000
sq. feet or gallons per acre) based on the chemical
manufacturers recommendations.
•
•
Use the tip chart on page 9 to determine what ground
speed will achieve the recommended application rate.
To determine the throttle setting for attaining the
desired ground speed, mark off 100, 200 and 300
feet intervals. The speed chart at the bottom of
page 9 indicates the number of seconds it takes to
travel these distances. Set the throttle and, with a
running start, travel the distances in the number of
seconds indicated by the speed chart. Once you have
determined the throttle and gear settings needed,
mark the throttle location so that you can easily
resume the same speed after stopping.
ATTENTION!
Do not allow chemicals to sit in pump for extended
times of idleness. Some chemicals will damage the
pump valve if allowed to soak untreated for a length
of time. Always flush the pump with water after each
use. See the instructions for cleaning the tank in the
maintenance section for flushing and disposal of
chemicals.
CAUTION: Wear eye protection, gloves
and protective clothing when handling
and working with lawn chemicals.
•
Add the chemical solution to the tank, following the
product instructions.
MAINTENANCE/STORAGE
CUSTOMER RESPONSIBILITIES
•
Read and follow the maintenance schedule and the maintenance procedures listed in this section.
MAINTENANCE SCHEDULE

CHECK FOR LOOSE FASTENERS
CLEANING STRAINERS
•
Before each use make a thorough visual check of
the sprayer for any bolts and nuts which may have
loosened. Retighten any loose bolts and nuts.
•
Periodically clean the strainer in the end of the intake
hose at the bottom of the tank. Remove the nylon
swivel nut from the hose, pull out the screen and flush
it with clear water.
CLEANING TANK
•
Periodically clean the strainers in the boom nozzles.
Remove the nozzle, pull out the screen and flush it
with clear water.
•
•
After use, fill the tank part way with water, start the
sprayer and allow clear water to be pumped through
the plumbing system and out through the boom
assembly and the handgun. Use the handgun to
thoroughly wash all internal parts of the tank, the
outside of the tank and the boom.
Refill the tank about half full with plain water and
a chemical neutralizer and repeat the cleaning
instructions above. Flush the entire sprayer with the
neutralizing agent. Follow the chemical manufacturers
instructions for disposal of all wash or rinsing water.
STORING
•
Drain all water out of the sprayer, paying special
attention to the pump and handgun. These items
are especially prone to damage from chemicals and
freezing weather.
The sprayer should be winterized before storage by
pumping a 50-50 solution of water and R. V. antifreeze
through the entire plumbing. Proper care and
maintenance will prolong the life of the sprayer.
•
LUBRICATION
Oil the wheels at least once a season.
