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
chemical neutralizer, such as 'Nutra-Sol', or equivalent, and
repeat cleaning instructions above. A mix of water and some
detergent, such as 'Dawn' dish soap would be a sufficient
alternative.
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.
After Spraying
Warning: Do not use the tank as a container for fuel oils,
kerosene, gasoline, or any other petroleum distillate product.
All polyolefins are softened and permeated by such
products. In an enclosed area the vaporization of these
materials from the outside surface of the tank could create a
dangerous condition.
The tank should not be used as a pressure vessel nor used
with chemicals or solutions having a weight of more than 12
pounds per gallon.
Store the tank in a dry dark place when not in use. Storage
out of sunlight will prolong the life of the trailer.
Do not drop, strike, or kick the tank, especially at low
temperatures. Tanks become brittle and are subject to
cracking at temperature below 20 Fahrenheit.
Always flush the tank with water and a neutralizing agent
(such as 'Nutra-Sol') at the end of each use, to prevent
contamination of solutions.
Roller pumps are positive displacement pumps, which means
that the entire solution being pumped must go somewhere or
the pump will break. In this roller pumping system, solution is
drawn from the tank, and forced to a planned source, such as
boom nozzles, or handgun. The pressure is controlled by a
pressure relief valve, which is a spring-loaded device that
controls the amount of fluid bypassed (or recirculated) to the
tank. The gray handle is to be tightened to increase pressure,
and loosened to decrease pressure.
The 'Tee-Valve' is the on/off control which allows the operator
to manually control the solution going to the boom.
Tank Care and Maintenance
Information About The Sprayer
Winter Storage
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.
Testing the Sprayer
Attach the sprayer to the tractor 3 point hitch. Mount the
pump to the PTO and affix the torque chain.
Open the tank lid and be sure the tank is clean and free
of foreign material. Fill the tank about 1/2 full with plain
water.
NOTE:
It is VERY important for you to test your sprayer with
plain water before actual spraying is attempted. This
will enable you to check the sprayer for leaks,
without the possibility of losing any expensive
chemicals.
Before starting, open the suction line valve (located
underneath the carrier frame), turn the relief valve handle
out to lower the line pressure. This will help prime the
pump.
CAUTION: Always be sure that the water (or solution)
has reached the pump before starting your sprayer. If
the pump is allowed to run dry, serious damage to
the pump will result.
Always have the pressure line open to the tips so that the
air which may be trapped in the line will be forced (or
purged) out.
Start the tractor PTO. Check the entire system for leaks.
Once the pump is primed, the pressure may be increased
by turning the handle of the pressure relief valve in. Keep
the pressure line open to the tips when setting the
pressure. Set the pressure and then lock the relief valve
handle in place. Shut off the directo-valve and check for
leaks again. Pressure will increase when the pressure
line valve is closed and then return to the preset pressure
when the valve is opened again.
During the testing period, be sure to observe the spray
pattern given by the spray nozzles. 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.
