Overview of the ESS MBP 2.5/4.0
Air-assisted Electrostatic Sprayer
Air-assisted electrostatic sprayers produce electrically charged spray
drops that are carried to the plant canopy in a low pressure, gentle, air
stream. The heart of the MBP Mountain Man Sprayer is the patented
MaxCharge™ nozzle.
Air and liquid enter separately at the rear of the nozzle. Just before
leaving the nozzle, the air hits the liquid stream to make many thousands of tiny spray droplets that pass through the charging ring. An
electrical charge is applied to the spray droplets by the charging ring.
Then the charged spray droplets are blown out of the nozzle and
move into the plant canopy where they are attracted to plant material
by electrostatic forces. The electrostatic charge induced by the MaxCharge™ nozzle is strong enough to allow the droplets to move in any
direction to cover all plant surfaces, even defying gravity to coat the
underside of leaves and the back side of fruits and vegetables. The result is uniform spray coverage on hidden areas deep inside of the plant
canopy where other sprayers miss.
The MaxCharge™ nozzle is easy to clean and corrosion-proof. The interior ceramic outlet resists wear three times better than stainless steel
outlets. These features combine to give the best spray coverage on the
market. This quality product is virtually maintenance-free, and assures
you of savings in the application of chemical.
The comparison of air-assisted electrostatic spraying versus conventional spraying is dramatic.
Electrostatically charged droplets are
attracted to plant surfaces.
Where Does the Spray Go?
The University of California completed a series of tests to investigate what happens to spray liquid after it leaves the nozzle.
Conclusion: ESS technology places over 4 times the amount of
spray onto the plant surface using ½ the amount of chemicals.
Furthermore, they also reported that ESS sprayers send ⁄ less
chemicals to the ground and into the air. Less chemical used
overall, less waste and less drift than conventional equipment.
Imagine the environmental benet!

About the low-voltage system of the MaxCharge spray gun
9v
For operator safety, the MaxCharge spray gun is powered by a lowvoltage power supply. The rechargeable 9-volt batteries are in the
handle of the MBP spray gun. The electrostatic charge imparted to the
spray is not strong enough to harm people. Some people report feeling a “tingle” or a slight stinging sensation when the spray from the
nozzle falls on their bare skin.

to an external air source. Combining the best features of a
backpack spraying system with
the versatility and convenience
of a mobile air supply, the
MBP 2.5 /4.0 allows workers to
travel faster and further than
before. Although it is possible
to use the Mountain Man solo,
it is much more eciently used
by a two-man team. The ergonomically balanced cart has
handles fore and aft; one team
member can push and one can
pull. The backpack can be prelled with the chemical mixture
and carried along to a remote
location as the team moves
the cart. When the compressor
cart is in the desired location,
simply pull down the kickstand,
hook up the backpack, start the
gasoline-powered compressor,
and begin spraying.

Operating Instructions
All operators must read this Owner’s Manual completely and
thoroughly before operating the MBP 2.5 / MBP 4.0 sprayer.
They must be familiar with all operating instructions and
safety precautions.
Unpacking and assembling the sprayer
In the shipping box there should be
one spray gun in a box,
one backpack tank assembly,
one cart assembly,
one 30.5-meter (100-foot) air hose, and
one MBP Parts Kit.
Carefully open the spray gun box, remove the spray gun, and unwrap
the bubble wrap from the spray gun. Store the box and bubble wrap
for future shipping. The air hose is wrapped with a strap for shipping;
cut this strap.
Lay the backpack tank face down. Both shoulder straps are permanently attached at the top. To attach the bottom of the left shouder strap,
please follow these steps:
1. There is a hook on the bottom of the strap. Turn the strap
so that the end of the hook is pointing down
2. On the bottom right side of the back of the tank there are
two square holes in the metal rim. Insert the hook into the
bottom square hole from the top.
3. Turn the hook 180°.
4. Pull on the hook so that the end comes up through the top
square hole.
5. Pull the hook towards the top of the tank so that it will not
slip out.
6. The second strap simply hooks under the stainless steel
ring at the bottom of the tank.
The cart has had its handles and wheels removed for shipping. To prepare the cart for operation, fasten the handles and wheels onto the
cart.
The Parts Kit contains a collection of small parts commonly needed to
maintain and repair your MBP sprayer. Please store it in a safe place for
future use. Among the items in the Parts Kit you will nd one extra ow
disk and one extra strainer. We call your attention to these parts because they are indeed very small and easy to overlook; however they
are essential for your sprayer to run correctly. (See the section about
the air lter for detailed instructions on cleaning and replacing the air
lter. See the section on the liquid lter to clean or replace the ow
disk and the strainer.)

Compressor
NOTE
The compressor produces pressurized air which is used to atomize and
propel the liquid spray. The oil level should be checked before each
spray application. Use only 30-weight compressor oil in the compressor. Follow the Maintenance Schedule on page 9 for periodic engine
maintenance procedures.
Backpack tank
The MBP-4.0 is equipped with a 15 liter (about 4 gallons) tank which
is worn on the operator’s back. The MBP 2.5 tank’s capacity is 9.5 liters
(2.5 gallons). For both models, the tank is opened by turning the tank
lid counter-clockwise until it can be lifted o and closed by turning the
tank lid clockwise on the tank opening until it ts tightly.
It is extremely important that you do not overll the tank. If the liquid
level is too high inside the tank, chemicals may spray out the air bleed
hole.
Be aware that the MBP Engine and compressor become hot during normal use.
To put the tank on your back:
1. Put your left arm through the left strap.
2. Pull the other strap over your right shoulder.
3. Hook the end of the strap hook on the base of the metal rim
4. Tighten or loosen the strap to make it t.
To take the tank o your back:
1. Unhook the end of the strap hook from the base of the
metal rim.
2. Pull your left arm out of the left strap.
The tank should be thoroughly cleaned immediately after each use by
triple-rinsing the tank. A commercially available tank cleaner (like Nutra-sol) may be used and is recommended when the MBP-2.5/MBP-4.0
sprayer is used to spray wettable powders on a regular basis.
Note: Do not operate the sprayer when the tank lid is not securely
closed. Chemicals may splash out onto the operator if the tank is open
during operation.
ESS recommends the use of
NUTRA-SOL cleaner which
can be purchased from ESS.

To connect the quick connects:
1. Slide the sleeve of the quick connect socket up.
2. While holding the sleeve up, push the socket onto the quick
connect plug.
3. Release the sleeve.
4. Pull on the socket body to ensure that it is properly seated
and cannot be pulled o the plug when the sleeve is down.
The air connection
The quick connect for the air connection is on the top of the air hose
storage rack. The other end of the air line hose connects to the air leader of the spray gun. The air leader of the spray gun is below the liquid
leader and is easily recognizable because its connector is larger than
the liquid connector – it is not possible to connect the air hose to the
liquid leader. The air line hose is red.
The liquid connection
The quick connect for the liquid line is on the bottom of the backpack
tank and connects the liquid leader of the spray gun. The liquid line is
gray and only long enough to allow the user to move freely with the
spray gun.

Nozzle assembly
It is very important to follow all the maintenance
and cleaning procedures to ensure that the electrostatic sprayer will function properly. Although the
MaxCharge™ nozzle will outperform all electrostatic
spray technology on the market, regular cleaning
will ensure peak operating performance.
The nozzle assembly is located at the end of the
spray gun wand. It is composed of a nozzle body,
internal o-ring, Teon ring, cover, external o-ring,
and a hood (see labeled drawing at right). To access
the nozzle components, just unscrew the nozzle
cover by hand.
Cleaning the spray gun
Always rinse the spray gun out with clean soapy
water after every day’s spraying. That is the most
important thing you can do to ensure trouble free
operation of your MBP sprayer. By cleaning after
each and every working day you will avoid the longterm chemical buildup that eventually causes clogs,
poor spray patterns and shortens nozzle life.
Establish maintenance intervals to disassemble and
clean the nozzle. Your nozzle maintenance schedule
will vary depending on the types of chemicals used
and adherence to pre- and post-spray checks. In
general it is sucient to thoroughly clean nozzles
every 50 hours. If heavy loads of wettable powers
are used, the cleaning schedule should be sooner.
To clean the nozzle assembly
1. Slide the hood over the nozzle cover.
2. Unscrew the cover from the nozzle base and remove the Teon ring. Clean any debris from
around the nozzle tip.
Note: There is a small o-ring in the nozzle around the base of the tip, take care that it doesn’t fall
o. If it does, clean it and press back into place. Also, take care not to damage the nozzle tip when
the cover is removed.
3. Soak the ring, cover, and hood in a mild detergent solution. Use a small brush (soft or mild
bristle) to clean the inside of the cover and the hole through it. Also, be sure to clean the hood.
It is important to clean inside the hood and the two cavities. Rinse thoroughly.
4. Scrub the nozzle base with the detergent solution using a soft bristle brush. Clean the ceramic
outlet. Be sure to thoroughly clean the base cavity and take care not to damage the nozzle tip.
Rinse and make sure the small o-ring is in place.
5. Reassemble nozzle by placing the Teon ring on the base and screwing the cover on hand
tight. Next, slide the hood over the nozzle and seat it securely against the external o-ring.
Wipe clean the exterior of all hoses and ttings connected to the nozzle.
The electrode cover should be hand tight. Never use pliers or other tools to tighten it. The insulating
ring should be loose.

You may wish to purchase Nutra-Sol Tank Cleaner from ESS (S/N#
1566), which cuts hard water scale and chemical deposits from the
electrode and internal component of the spray gun. The regular use of
Nutra-Sol will keep your equipment operating at peak performance.
The recommended mixing ratio is 4 ounces in 12.5 gallons of water
(113 grams in 47 liters of water).
Pre-spray check
I. Inspect Nozzles
Check nozzle cover to make sure it is on hand tight (do not
over tighten or use a wrench). Make sure the hood is seated
rmly to the nozzle base and against the external o-ring.
II. Preparing the Tank Mix
If you will be spraying wettable powders it is a good idea to
use a compatibility agent with the water and tank mix.
Compatibility agents are chemicals mixed with the water
that make mixing easier and keep heavy concentrations
uniformly in suspension. Some brand name additives are
COMPLIMENT™, UNITE®, and BALANCE™. Check with your
local chemical supplier for others that are available.
Post-spray check
ESS recommends the use of
NUTRA-SOL cleaner which
can be purchased from ESS.
Order S/N#1566.
After each spray it is essential that hoses and spray gun be
ushed with clean soapy water. This will help prevent
chemical build-up that can clog lines and nozzles. Also, it is
recommended that the nozzle exterior (black portion of
nozzle) and nozzle hoods be cleaned with soapy water at this
time.

Batteries
9v
The nozzle charging operates on two 9-volt rechargeable batteries
which are located in the base of the spray gun. In average conditions,
the batteries will last 10 to15 hours of operation on a charge. They
should be recharged when the charging indicator on top of the spray
gun shell doesn’t glow when air is going through the spraygun.
After approximately 800 to 1000 hours of service the battery pack will
no longer be able to hold an adequate charge and will need to be replaced. Replace with nickel-hydride rechargeable batteries. Order the
MBP’s replacement battery pack from ESS.
Remember to charge the
spray gun batteries after
every work session!
To change the batteries:
1. Unscrew the two 6-32 x ½” Phillips head machine screws
which hold the battery cover in place.
2. While holding the leads in one hand, gently disconnect the
batteries from the leads. Be careful not to tear the leads o
the wires or to tear the lead wires out of the power supply.
3. Connect the fresh battery pack to the leads.
4. Replace the battery cover. Screw the two 6-32 x ½” Phillips
head machine screws back in to secure the battery cover.
5. Charge the spray gun before attempting to use it.

Spraying with your ESS sprayer
Note: When using unfamiliar equipment or chemicals, always test on a
small area before treating the entire crop or surface. Do not use a chemical
with the ESS sprayer if the label prohibits use in low-volume sprayers.
Spray Technique
As in spray painting, the goal is to achieve even coverage over the surface. The ESS MaxCharge spray gun is designed to help you do just that
-- by propelling the chemical spray with a gentle air ow, you can stay
well away from the target surface and let the electrostatic attraction do
the rest of the work.
Please note: the spray droplets are very, very ne --- about 40 microns
each. If you are used to working with a conventional sprayer, you may
make the mistake of thinking the target is not wet enough because
you do not see large beads of liquid. In fact, after a pass with theMBP’s
MaxCharge spray gun, the surface of the target should just barely glisten with moisture. The ne droplets will evaporate quickly.
Here are some tips to achieve the best possible coverage with the ESS
MBP sprayer.
1. Before each job, ensure that your sprayer is in good
working order (see the pre-spray checklist on page XX of
this manual).
Let the MaxCharge™ Spray
gun do the work!
There’s no need to stick the tip
of the spray gun into the plant
canopy. The electrostatically
charged spray will blow into
the plant canopy and the droplets will even change direction
to nd a dry surface to cling to.
2. The optimal spraying distance is at least 18 inches away
from the target surface, however 36 to 48 inches may
provide a more even coating. This gives the ne mist
produced by the MaxCharge nozzle room to develop into a
chaotic cloud that will be attracted to the target surface.
3. Hold the spray gun at right angles to the target surface.
Starting at the highest point and using zig-zag horizontal
strokes about 1 meter (3 ft.) wide, spray down to the
lowest point. Try to have each stroke overlap the previous
stroke by about 50%.
4. You can use vertical strokes if it suits the area better. Just
make sure to work in a methodical pattern and let your
strokes overlap.
5. When moving to the next section, allow it to overlap the
previous section by a few inches. Do not leave a gap.
6. The target surface should just barely glisten with the spray.
Do not over-saturate the surface; if you see runs or puddles
it means you are wasting chemicals. Do check to make sure
the newly-sprayed surface is very slightly damp.
7. Be careful to keep the spray gun barrel as level as possible.
If you allow the nozzle to point down too much, it may drip
occasionally.
8. Unlike spray painting, you don’t have to stop the spray on
every return stroke. Just engage the trigger lock and
concentrate on the regular pattern of spraying.
9. Periodically check to make sure the red light is illuminated
on the spray gun.

Preparing a tank mix

The tank mix depends on two factors: water requirement and dosage.
Water requirement is the amount of water needed to cover the given
treatment area. Dosage is the amount of chemical which should be
applied in a given treatment area.
First determine the water requirement for your sprayer over a known
area. An easy way to determine water requirement is to spray a trial
application with water. Put a gallon of clean water in the ESS SC-1 tank
and thoroughly spray a known area. After spraying the known area,
determine how much water was used from the amount left in the tank.
This is the water requirement for the given area. Next measure the
known area to determine how many square feet were sprayed. Write
down both values for future reference.
___________ (gallons) Water Requirement
for __________________ (size of known area in ft)
Next determine the dosage. This is the amount of chemical you wish to
dispense in a given area. Appropriate dosage depends upon chemical
label recommendations, disinfection or sanitization goals, level of pest
or disease infestation, past experience with particular chemicals, and
other variables.
Because electrostatic spraying is a much more eective spraying method, ESS recommends that you experiment to nd the optimum chemical concentration. Start spraying using the same chemical rate used in
the past with either hydraulic or air assisted sprayers. For example, if
in the past you have used 2 ounces of chemical in a hydraulic sprayer
to spray a known area; then mix 2 ounces of chemical to the water
required by the MBP to spray the same known area. In other words, the
same amount of chemical is sprayed out in the area but with much less
water.
DO nOt
OVerfill
tHe tanK
ESS recommends that the tank not be
lled past the full level mark, since the
force of agitation may cause liquid to
escape through the air bleed hole in the
tank lid.
Example:
You have two greenhouses covering 10,000 square feet that are sprayed using a conventional hydraulic sprayer. In the past you mixed 6 ounces of chemical to 25-50 gallons of water in order to spray both
house at full rate.
With your new ESS sprayer you need to nd out how much water is needed to spray the known area.
The amount of water required to spray both houses is the amount of water in which you mix the
6 ounces of chemical in. Depending on the crop sprayed, you will use approximately 1to 2 gallons of
water with the ESS sprayer to cover 10,000 square feet. This applies to all chemicals, even wettable
powders.
ESS MBP 2.5 / MBP 4.0 MOUNTAIN MAN OWNER’S MANUAL
21
Page 28
After becoming familiar with the sprayer spraying at full rate, you can
start reducing the amount of chemical used for each spray. Keeping
the amount of water in the tank constant, cut the amount of chemical
mixed in by 15 to 25% for each spray until a desirable kill is no longer
achieved. If you are planning to cut rates then it is very important to
scout your crop to determine spray eciency.
Chemical compatibility
It’s sometimes desirable to spray a mixture of two dierent chemicals
at the same time. It is good practice to conduct a jar test to determine
if the chemicals to be mixed are compatible. If they are not, then investigate alternative chemicals or use a compatibility agent to maintain
the chemicals in suspension. It is also a good idea to treat the water
with a pH agent.
ESS does not recommend the use of wetting agents or
spreader-stickers.
How to conduct a jar test
Needed:
Solutions of chemicals in
approximate dilutions
Jar with lid
Gloves and Safety
Glasses
After mixing solutions of
the desired chemicals, place
them in a large jar, cap it securely, and shake vigorously.
Carefully observe the interaction between the chemical
compounds. If the water
becomes milky or cloudy, the
combined solution may plug
the nozzles. Let the jar sit for
one to two hours. If there is
precipitate on the bottom
of the jar, then seek another
combination of chemicals.
A note about operating temperatures
The MaxCharge nozzle should always be operated at temperatures
above 10° Celsius (50° Fahrenheit). When the ambient temperature is
colder than this, the evaporative cooling caused as the spray is atomized will freeze the nozzle opening.
Nozzle freeze-up can also occur when the liquid to be sprayed is colder
than 10° C (50° F).
IMPORTANT
Water temperature must be at least
10° C (50° F). When the liquid and air
meet in the nozzle, the temperature of
the liquid deceases. As a result, water at
temperatures below 10° C (50° F) may
freeze and clog the nozzle.

Spraying with optional spray guns
Spray guns with multiple nozzles are available as optional equipment for your MBP 2.5/4.0 sprayer.
Triple- and double- headed spray guns
are available as optional equipment for
your MBP “Mountain Man” sprayer.
Whenever you use a multi-head spray gun, there are trade-os in the
amount of liquid sprayed out and the distance covered. A two-headed
spray gun will deliver more liquid, the spray swath will be wider, however, the distance the spray can travel will be reduced.
For example, a single-nozzle spray gun sprays 170 mL/minute and
sprays 15 to 20 feet* (4.6 m. to 6.1 m.). A two-headed spray gun, with
all other conditions the same, will deliver 200 mL/minute and only
reach 12 to 15 feet (3.7 m. to 4.6 m.).

Siphoning
The MBP 2.5/4.0 sprayer’s design relies on siphoning of the liquid from
the backpack tank. If your spray gun is held above your head, the
liquid will not spray properly. To get the best performance from your
sprayer, hold the spray gun no higher than your shoulder.
