! Safety Precautions !
General Guidelines
Every year many unnecessary accidents occur due to improper equipment handling and a
disregard for safety precautions. You, the operator, can avoid accidents by observing the precautions in
this section.
The operator should be a responsible
adult. Do not allow persons to
operate this sprayer until they
have displayed a thorough
understanding of sprayer safety precautions and
operational use!
All operators must fulfill all necessary state
pesticide applicator license requirements!
Never attempt to operate this sprayer when under the
influence of alcohol or drugs.
A chemical warning decal and an owner's manual
warning decal are located on the sprayer's tank. Be aware of their location. See Figure 1
and Figure 2. Always replace any warning decals that aren't legible or are missing.
If there is any portion of this manual that you do not fully understand, please contact
PaulB LLC.
Before Operation
Carefully study and understand this owner's manual.
Read and follow chemical manufacturer's labels, warnings, and instructions!
A material safety data sheet (MSDS) should be provided by the chemical manufacturer.
To avoid injury from chemical hazards, wear the proper protective clothing. Each
chemical manufacturer's clothing requirements are listed under the
“Personal Protective Equipment (PPE) section in the chemical instructions.
Never exceed the load rating of the piece of equipment that the spot sprayer is mounted
on. The 40 gallon spot sprayer weighs around 375 lbs. with a full tank.
Have all operators practice operating the sprayer until all persons are completely capable
of safe operation.
Give the sprayer a visual inspection for any worn parts, leaking hoses, or other
visible problems, and make the necessary repairs. See the maintenance section(page 6).

Figure 2: Owner's Manual Decal(# DE39)

During Operation
Always be aware of bystanders, particularly children!
DO NOT allow passengers to ride on the equipment the sprayer is mounted on.
Be aware of dangerous terrain such as holes, slopes, drop-offs, banks, rocks, and hidden
hazards. Operate the equipment and sprayer up and down slopes, not across.
Never leave running equipment unattended!
Remember that accidents can even happen to seasoned operators. Always take your time
and follow all safety instructions.
Following Operation
Always rinse the tank and flush the pump of all harmful chemical residue.
Store the sprayer away from human and livestock activity and in an area protected from
the elements.
Do not permit children to play on or around sprayer.
Pump Safety Precautions
Never pump flammable, explosive, petroleum-based, or any other non-compatible
products such as gasoline, fuel oil, kerosene, etc. Such practices will void the
manufacturer's warranty.
DO NOT allow the pump to get wet or to be exposed to the elements. Allowing the
pump to get wet or to be exposed to the elements voids the manufacturer's warranty.
Note: The pump may be run dry for limited periods without resulting in damage.
Never attempt to adjust the pressure of the pump. Any unapproved pump adjustment will
void the manufacturer's warranty.
Always disconnect the power to the pump when working on the pump. Failure to do this
could result in electrical shock.
Mounting the Sprayer
This spot sprayer is designed to be mounted on the rack of an ATV, on a garden trailer, or on a
utility vehicle such as a John Deere GatorTM. Mounting the sprayer correctly and securely will ensure
consistent and safe spraying.
Page 3

Sprayer Unit
1. Before mounting the sprayer on any piece of equipment determine whether the sprayer
weight exceeds the equipment manufacturer's load rating. The 40 gallon spot sprayer
weighs around 375 lbs with a full tank.
2. The sprayer tank is mounted on a steel
powder-coated frame with four pre-drilled
holes. For optimal stability mount the
sprayer with bolts using the pre-drilled
holes in the sprayer frame. See
Figure 3 on page 4. For some temporary
situations it may make more sense to strap
the spray down with heavy-duty straps. If you choose to strap the sprayer down ensure
that it is fastened securely.
Wiring Harness
1. The spot sprayer includes an eight foot wiring harness with a built in fuse and control
switch. The end of the wiring harness with a two-prong plug needs to be connected to
the pump's adapter plug.
2. The other end of the wiring harness needs to be attached a power source with at least a 10
amp and 12 volt capability. In most cases the power source is the 12 volt battery on the
piece of equipment being used(ex battery on an ATV, mower, utility vehicle). Attach the
red wire's ring terminal to a positive power source and the black wire's ring terminal to a
negative power source. See the Accessories section on page 12 if additional wire
length is needed.
3. The wiring harness also is equipped with an in-line on-off control switch. This control
switch should be positioned in a location that is easily accessible and will not interfere
with operation of the piece of equipment. The control switch can be strapped into place
if appropriate.
Page 4
Note: If you are permanently mounting the sprayer in an outdoors location that isn't protected
from the elements, it is important that you cover the pump to protect it.
Note: The end of the wiring harness with the ring terminals is detachable and can be left
attached to the battery for convenience purposes.

Operating Instructions
Before operating the sprayer, it is important that you read this entire manual and know all safety
precautions. Always take your time and be alert when operating your sprayer. This will allow you to
safely spray without accident or interruption.
Before and During Operation:
1. Before operation it is important to give the sprayer unit a thorough inspection, which
covers the hoses, wiring harness, and other sprayer components. Ensure that the suction
strainer and the tank are rinsed out.
2. Before using any chemical or product ensure that it isn't a petroleum-based product or a
non-compatible chemical for the pump. Using petroleum-based products or non-
compatible chemicals voids the manufacturer's warranty. If you are unsure of the
acceptableness of a chemical or substance, contact PaulB LLC.
3. Fill the sprayer tank with the amount of water and chemicals as instructed by the
manufacturer of the chemical being used.
4. Connect the wiring harness to an approved power source as directed in the Mounting the
Sprayer section on page 3. Turn the control switch to the on position and allow the pump
to run until it reaches its maximum pressure. The pump will automatically turn off when
its maximum pressure is reached. The pump does not need to manually turned off with
the control switch.
5. When you are ready to spray, point the gun in the desired direction and squeeze the
trigger on the spray gun. The pump will automatically start when the spray gun is
engaged.
6. The spray gun's liquid flow can be adjusted by turning the spray tip at the end of the
spray gun wand. The spray gun's trigger can also be locked in the “on” position by
sliding the plastic tab on the top of the trigger towards yourself.
Following Operation:
1. Thoroughly rinsing the sprayer of any chemical residue is an important activity. It is
recommended to fill the tank with fresh water and engage the spray gun until the system
is entirely free of chemical residue. It is important not to rinse the sprayer in an area
where humans, animals, or sensitive plants could come in contact with chemical residue.
2. Store the sprayer in a location where it will be away from human or animal activity. Do
not allow children to play on or near the sprayer.

Maintenance Instructions
Routine Maintenance
It is very important to perform routine maintenance on your sprayer before and after each use.
Good maintenance practices will help to guard against any unnecessary sprayer breakdowns or
accidents.
1. It is recommended to perform a visual and physical inspection for any worn parts,
damaged hoses, or other visible problems. Make all necessary repairs before spraying.
See the Contact Us section (page 13) for instructions on ordering parts and getting
technical help.
2. After each use it is important to rinse the pump and all components by running water
through the system. Fill the tank with a sufficient amount of fresh water and engage the
spray gun. Rinsing the pump with fresh water will greatly improve the life of the pump!
3. The suction strainer should be taken out and rinsed regularly.
4. Always follow all pump safety precautions and warnings (page 3). Following these
guidelines will help to ensure many years of smooth and trouble-free pumping.
Winterizing your Sprayer
To avoid damage from freezing and corrosion, it is important to winterize your sprayer before
temperatures grow too cold.
1. Verify that the tank is empty and rinsed out. Dump a ½ gallon of RV nontoxic antifreeze
into the tank. It is not recommended to use standard antifreeze. Standard antifreeze
can be harmful to humans, animals, crops, and the environment.
2. Engage the pump and spray with the spray gun for several minutes. Ensure that the
antifreeze has been pumped through the entire system.
3. Store the sprayer in a dry location away from the elements.
4. Before spraying in the spring it is recommended to flush the sprayer with fresh water to
cleanse it of the antifreeze and any other buildup. It would also be beneficial to do a
thorough inspection of all sprayer components before spraying.
