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

chemical neutralizer, such as 'Nutra-Sol', or equivalent,

and repeat cleaning instructions above. A mix of water and

some good quality dish detergent 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.

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.

Troubleshooting the Pump:

Pump will NOT run:

- Check inline fuse on the wires on the pump.

- Make sure on/off switch is in the 'on' position (-).

- Make sure you 12 volt source (battery) is fully charged.

- Insure a tight connection at the battery clips.

If none of the above will work, try pulling the wires off the

pressure switch, and short them out. If your pump runs

when you do this, you know you will need to replace

your pressure switch.

Pump runs, but does not prime:

- Check line strainer (screen) in the tank, connected to

the bottom of the intake tube. Periodically take the

screen at this location out and clean it.

- Make sure the bypass line valve is closed, to allow the

pressure to build up in your system. (If equipped with

bypass)

Operation

Your sprayer may be equipped with (2) ON/OFF switches.

One on the wire assembly that you hook up to your battery,

the other is on the pump itself, on the opposite end of the

pressure switch. The "-" is the "ON" position and the "o" is

the "OFF" position for the switches. Make sure both

switches are depressed in the "-" position for operation.

In addition to the ON/OFF switch, the pump is equipped with

an electronic pressure switch that is factory pre-set for it to

shut off at 60 p.s.i.. This switch assembly is the 'square box'

on the head portion of the pump.

Always fill the tank with a desired amount of water first, and

then add the chemical slowly, mixing as you pour the

chemical into the tank. You may use the handgun to spray

into the solution in order to mix the chemical and water.

Initially begin spraying by opening the handgun. This will

enable the air in the line to be purged through the handgun

tip, while building pressure.

The pumping system draws solution from the tank, through

the strainer/filter, and to the pump. The pump forces the

solution under pressure to the handgun and/or boom

nozzles.

Open the handgun by squeezing the handle lever.

•

Rotating the adjustable nozzle tip on the handgun will

•

change the tip pattern from a straight stream to a cone

pattern (finer mist).

- Unscrew the head portion of your pump and remove the check

valve assembly from inside. You need to make sure the O-Ring

comes out with this piece as well. (See the exploded view to

help identify these components) These pieces can be cleaned

which, in most cases, will help restore some, if not most, of your

prime. Soak this check valve in a solution of hot, soapy water. A

good name-brand dishsoap works well for this. A little bit of

'scrubbing' with perhaps an old toothbrush may be required to

actually break up any build-up that may be on the check valve.

Rinse off the pieces and replace them back into your pump.

Reassemble the pump. Hook it back up and test.
