3 STAGE FILTERING SYSTEM

This backpack sprayer is equipped with a 3 stage ﬁltering system (see

ﬁgure 1). Stage 1 is a ﬁlter basket incorporated into the tank opening

where ﬂuid is added. Stage 2 ﬁlter is located at the inlet of the pressure

cylinder. Stage 2 is a removable In-Tank ﬁlter. Stage 3 is a removable ﬁlter

incorporated into the shut-off assembly. Periodic cleaning of these ﬁlters

is recommended to insure consistent ﬂuid ﬂow through the sprayer. This

will also reduce sprayer component wear.

The stage 3 ﬁlter is a removable ﬁlter incorporated into the inlet side of

the shut-off valve (see section “disassembling and repairing the shut-off

valve”). Make sure pressure is released before detaching the hose from

the shut-off. It is best to have no or minimal ﬂuid in the pressure cylinder

before removing and reinstalling the stage 3 shut-off ﬁlter as ﬂuid can

leak from the hose.

BASIC USE OF MIXES ON EXIT™ SETTING ADJUSTMENT

Set sprayer knob adjustment to desired amount of concentrate sprayed per gallon. Fill Chemical tank with

exact amount of chemical to cover the square footage per Chemical manufacturer’s instructions. Example:

1 ounce for 10 square feet. Evenly spray and cover the desired 10 square foot area until concentrate tank is

empty. Note: Setting 1 will mix less chemical with water - setting 7 will allow more concentrate to be mixed

with water when spraying. The water is the vehicle in which the chemical is being delivered. As long as you

cover the desired predetermined area with the appropriate amount of chemical the amount of water is

inconsequential. Setting the mix ratio helps you control how quickly the chemical is delivered per gallon.

FINE TUNING YOUR MIXES ON EXIT™ SPRAYER

(Use this process for calibrating your mix ratio settings)

1) Fill the concentrate tank and backpack tank - both with water.

2) Weigh the Concentrate tank and record the weight.

3) Set the dial to the desired position (example: set to 1 for 1 ounces per gallon).

4) Weigh your empty bucket (record the weight for future reference if your scale doesn’t have a

tare function).

5) Keeping the bucket on the scale, spray 1 gallon of water (adding an additional 8.34 lbs to the

empty weight of your bucket).

6) As you spray, keep your pump strokes consistent for most accurate measurement.

7) Remove the concentrate tank from the backpack sprayer and weigh the tank with it’s remaining

chemical in the tank.

8) Subtract the current weight of concentrate tank from the weight recorded in step 2.

9) Calculate the mix ratio using the following equation:

10) If results are slightly off from the expected mix ratio,

set knob –/+ to accommodate variance and retest to conﬁrm accuracy.

Once conﬁrmed note setting that provides exactly 1 ounce per gallon.

11) Repeat as needed for a range of settings

Mix Ratio = 127.9356

NOTE:

• Always follow chemical manufacturer’s instructions.

• When not spraying, set mix ratio dial to zero.

• Approximate mix ratios based on chemical concentrates

with approximate viscosity to water while pumping at a

rate of 60 beats per minute.

• Pumping faster than 60 BPM will result in higher mix ratios

and pumping slower will result in lower mix ratios.

HELPFUL SPRAYING INFORMATION

Use RAPID pump strokes to prime the pump. You will know the pressure chamber is ﬁlling with liquid

when you feel ﬁrm resistance from the pump. The air in the pressure chamber is compressed from

repeated strokes. By pressing the hand lever on the shut-off, the valve opens. For safety lock-off feature

(no-spraying), pull up on handle and move red locking mechanism into lock-off position as shown in ﬁg.

1. To disengage, pull up on handle and return red locking mechanism to neutral position as in ﬁg. 3. For

lock-on feature (continuous spraying), push down on handle and move red locking mechanism into lock-

on position as shown in ﬁg. 2. To disengage, push down on handle and return red locking mechanism to

neutral position as shown in ﬁg. 3.

LOCK-ON POSITION NEUTRAL POSITIONLOCK-OFF POSITION

Locking Mechanism Handle

Figure 1 Figure 2 Figure 3

For easy pump action use the END of the pump handle. The amount of liquid delivered during spraying depends

on the rate of pump stroke. The fan nozzle tip is rated at .4 gpm at 40psi. This is the nominal operating pressure

of the sprayer.

Note: If you experience a rapid drop in pressure, drain the sprayer completely and pump the handle with

an empty tank. The pressure chamber will ﬁll with the required volume of air to repressurize. Perform this

procedure from time to time as routine maintenance.

CLEANING

1) Always empty the sprayer and clean the tank thoroughly after each use.

2) Pump the sprayer handle until all of the contents and air exit through the nozzle (minimum of 30 strokes).

3) Fill tank half way with water and pump the water out as explained in step 2 (repeat several times

as necessary).

Other Cleaning Hints:

• Improper spray distribution usually means the nozzle is clogged, remove the nozzle and clean it.

• Soap can be added to the water to clean the tank.

• Do not use strong cleaning agents or abrasives.

• If you use a chemical agent to clean the tank follow the manufacturer’s recommendations for the

disposal of the waste water.

• Follow the chemical manufacturers instructions for clean up.

Chapin Backpack Sprayer Operator’s Manual - English

STORING / MAINTAINING YOUR SPRAYER

• The sprayer should be stored out of direct sunlight in a cool dry space.

• Before freezing weather make sure to drain all liquid in the tank, pump, pressure cylinder, hose,

shut-off valve, wand and nozzle, to avoid liquid expansion and cracking in the sprayer components

(See “Cleaning” section). Lock the shut-off valve in the “open” position.

• When service is required call your nearest dealer and always insist on original manufactured

replacement parts.

• Inspect the hose, wand, pump, tank and shut-off valve for wear, damage or leaks on a regular basis

and repair defects promptly.

Este pulverizador de mochila está equipado con un sistema de ﬁltración en 3 etapas

(ver Figura 1). La etapa 1 es una canastilla de ﬁltro incorporada en la abertura del

tanque donde se coloca el ﬂuido. El ﬁltro de etapa 2 está ubicado en la entrada del

cilindro de presión. La etapa 2 es una varilla de ﬁltro desmontable. La etapa 3 es

un ﬁltro desmontable integrado en el montaje de cierre. Se recomienda limpieza

periódica de estos ﬁltros para garantizar un ﬂujo uniforme del ﬂuido a través del

pulverizador. Esto también reducirá el desgaste del componente pulverizador.

El ﬁltro de la etapa 3 es un ﬁltro desmontable incorporado en el lado de la entrada

de la válvula de cierre (vea la sección “desarmado y reparación de la válvula de

cierre”). Asegúrese de liberar la presión antes de retirar la manguera del dispositivo

de cierre. Es mejor tener una cantidad mínima o nada de líquido en el cilindro de

presión antes de retirar y reinstalar el ﬁltro de cierre de la etapa 3, ya que el líquido

podría gotear por la manguera.

LLENADO DEL TANQUE DEL PULVERIZADOR

Asegúrese de que la canastilla de ﬁltro esté en su lugar para evitar que entren

residuos al tanque. Llene el tanque del pulverizador con agua.

LLENADO DEL TANQUE DE SUSTANCIA QUÍMICA

Empuje el tanque de sustancia química hacia arriba (ﬁgura 1), y

luego sáquelo (ﬁgura 2).

Coloque el tanque de sustancia química en una superﬁcie plana y

llénelo con la cantidad deseada de sustancia química.

Siempre siga las instrucciones del fabricante de la sustancia

química. Inserte el tanque de sustancia química en el pulverizador

hasta que escuche un chasquido.

Uso básico del ajuste de Mixes On Exit™

Coloque la perilla del pulverizador en la cantidad deseada de concentrado esparcido por galón. Llene el

tanque de sustancia química con la cantidad exacta de sustancia química para cubrir el área deseada,

siguiendo las instrucciones del fabricante de la sustancia química. Ejemplo: 1 onza por 10 pies cuadrados.

Pulverice de manera uniforme y cubra el área deseada de 10 pies cuadrados deseados hasta que el tanque

de concentrado esté vacío. Nota: La posición 1 mezclará menos sustancia química con agua; la posición

7 permitirá que se mezcle más concentrado con el agua al pulverizar. El agua es el vehículo en el que se

esparce la sustancia química. Mientras cubra el área deseada predeterminada con la cantidad apropiada

de sustancia química, no importa la cantidad de agua. Conﬁgurar la relación de mezcla le ayuda a controlar

la rapidez con la que se esparce la sustancia química por galón.

Cómo aﬁnar sus mezclas en el pulverizador Mixes On Exit™.

(Use este proceso para calibrar su conﬁguración de relación de mezcla)

1) Llene el tanque de concentrado y el tanque de mochila, ambos con agua.

2) Pese el tanque de concentrado y anote el peso.

3) Coloque la perilla en la posición deseada (por ejemplo, en 1 para 1 onza por galón).

4) Pese su cubo vacío (anote el peso para referencia futura, si su báscula no tiene función de tara).

5) Dejando el cubo en la báscula, pulverice 1 galón de agua (sumando 8.34 libras adicionales al peso

vacío de su cubo).

6) Mientras pulveriza, mueva la bomba de manera uniforme para que la medición sea más precisa.

7) Quite el tanque de concentrado del pulverizador de mochila y pese el tanque con la sustancia química

restante en el tanque.

8) Reste el peso actual del tanque de concentrado del peso registrado en el paso 2.

9) Calcule la relación de mezcla usando la siguiente ecuación.

10) Si los resultados varían ligeramente de la relación de mezcla esperada, mueva la perilla -/+ para

adaptarse a la variación y repita la prueba para conﬁrmar su exactitud. Una vez conﬁrmada, anote la

posición que permita la mezcla de exactamente 1 onza por galón.

11) Repita las veces que sea necesario para diferentes conﬁguraciones.

Relación de mezcla = 127.9356

NOTA:

• Siempre siga las instrucciones del fabricante de la sustancia química.

• Cuando no esté pulverizando, coloque la perilla de mezcla en cero.

• Use tasas de mezcla aproximadas con base en concentrados químicos

con viscosidad similar al agua mientras bombea a una velocidad de

60 golpes por minuto.

• Bombear a más de 60 golpes por minuto generará tasas de mezcla

más altas, y bombear más lento generará tasas de mezcla más bajas.
