maintenance tip: Cap gasket is prelubricated for improved sealing.Occasional lubrication is recommended.

SAFETY PRECAUTIONS:

1. Before using sprayer with chemicals, fill sprayer with fresh water to assure that you have it properly assembled; pressurize and

practice spraying. Also, check for any leaks at this time. When thoroughly familiar with the sprayer operation, follow normal operating procedures.

2. Ensure all pressure in the sprayer is relieved by locking the shut-off valve in the open position.

3. Avoid contact with chemicals.

4. Always wear rubber gloves, safety goggles and appropriate protective clothing.

5. Work in a well ventilated area.

6. Individuals should be trained in the proper use of this sprayer, chemical handling procedures, and first aid/emergency care. Where training is not available, individuals should study and follow the procedures detailed in this manual.

WARNING:

Chemicals can be harmful to individuals and the environment if improperly used. In addition, some chemicals are caustic, corrosive or poisonous and should be avoided. Read warnings and chemical manufacturers’ instructions. Hudson high density polyethylene sprayers are fitted with Viton exercised to ensure that sprayer components are clean, functioning properly, and in a good state of repair before and during use. If in doubt about a particular chemical, check with the manufacturer. If you suspect or observe indications that the material may be unsafe in a Hudson sprayer...STOP. DO NOT USE OR APPLY CHEMICAL. ALWAYS WEAR RUBBER GLOVES, GOGGLES, AND APPROPRIATE PROTECTIVE CLOTHING!

Read and follow operating instructions.• Do not fill with, use, or spray flammable materials.• Do not modify sprayer.• Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula.• Do not use disinfectants, solvents or impregnating agents unless first tested to ensure they are not harmful to the environment or • sprayer. Do not use liquids with a temperature above 110°F (43°C).• Wear appropriate protective clothing to prevent contact with chemical agents.• Rinse and clean sprayer thoroughly after using. Disposal of contaminated rinse should be in accordance with applicable ordinances. • Observe the precautionary instructions of the chemical manufacturer. DO NOT USE ANY ACID (INCLUDING CITRUS) OR CAUSTIC • CHEMICALS (INCLUDING BLEACH). Remember that a sprayer with liquid is a significant amount of weight (8 lbs. per gallon). Use caution when bending, leaning or • walking. Bend at the knees rather than the waist. During sprayer operation, the pressure cylinder (#4400240) contains compressed air and liquid. Compressed air and liquid under • pressure are inherently dangerous. Before making adjustments on sprayers fitted with a pressure regulating valve body (#4074323) or control knob (#4074344) located on the pressure cylinder or any other repair or inspection of any sprayer, be sure to relieve pressure through the shut-off valve and wand.

Removing plastic adjustable nozzle

Unscrew the nozzle cap (1) from the nozzle body (3). This is best accomplished while the retaining nut (2) is fastened tightly to the elbow (5). Next, unscrew the retaining nut (2).

pump leveR installation: All hardware necessary for pump lever installation is included with the sprayer. The pump lever (C) should be installed as follows: place lever handle (C) onto the shaft (A). Align bolt holes and install the two bolts (E) and washers (F); then tighten. To install pump lever on the opposite side, remove the stop plate (D) and washer, install the pump lever as above. The stop plate (D) should be mounted on the inner bolt hole with the closed end of the stop plate pointing downward on the opposite side of the pump shaft.

Push the nozzle body (3) out of the retaining nut (2). The filter with gasket (4) will come out with the body. To reinstall the nozzle, reverse the above instructions.

assembly instRuctions foR Wand

1. Insert wand into shut-off valve as shown.

2. Tighten the screw cap clockwise onto the shut-off valve.

sHouldeR stRap installation:

The top of the shoulder straps are pre-attached to the sprayer by means of a buckle. The lower end of the straps are attached by fastening the strap hooks to the metal frame between where frame exits the plastic tank and makes a bend.

filling:

Mix the spray formula and the proper volume of water in a separate container. Pour the mix through the filter basket in the tank opening. This keeps debris from entering sprayer. Add 2 or 3 gallons of spray formula mix. Pump the sprayer handle to prime the pump and fill the pressure cylinder. The volume of liquid in formula mix tank will appear to decrease as the pressure cylinder is filled. Liquid will flow through the top of the pressure regulator when the cylinder is completely full. Add the remaining formula mix to the tank. Remember that it’s not necessary to completely fill the sprayer tank each time. Mix only the amount needed to get the job done.

Always read and follow manufacturer’s instructions printed on the product label. This can save money and help prevent crop and environmental damage.

*Brass adjustable nozzle is not a standard item on all Hudson sprayers. Spray tips should be assembled as above for desired spray pattern.

spRaying:

Prime the pump with rapid pump strokes. When you feel very firm resistance, the pressure chamber is filling with liquid. With repeated piston strokes, the air in the pressure chamber is slowly compressed. By pressing the hand lever, the valve opens, and liquid is forced through the nozzle. The shut-off valve has a retaining clip which keeps the valve in the “OPEN” position for continuous operation. Pump using the end of the pump handle, as it is less fatiguing. The volume of liquid delivered varies with the working pressure which should be as high as needed to ensure an adequate spray pattern for each individual application.

NOTE: Should the pressure drop very quickly, drain the tank completely and pump without liquid. By this procedure, the air chamber is refilled with the required volume of air. It is advisable to pump the tank completely empty from time to time.

Wettable poWdeRs:

Avoid use in piston pump sprayer model 93425! The Hudson model 93475 sprayer with a diaphragm pump are generally resistant to abrasive materials and are recommended for this purpose. Note: If you use a wettable powder in your 93425 sprayer, be sure it is thoroughly mixed in the formula solution. Immediately after use, be sure to remove the piston, clean and lubricate the Viton® collar with petroleum jelly. Thorough flushing of sprayer will extend the life of its working parts. If you use wettable powders in the piston pump sprayer, be sure to inspect regularly for seepage around the piston and repair accordingly.

cleaning:

• After spraying, clean the tank thoroughly. If some

spray liquid is left inside, drain tank completely.

• Pumpingcausesairtobetakeninandtheremaining liquid to be discharged. Pump until liquid and air are coming out through the nozzle.

• Refilltankwithafewquartsofcleanwaterandpump

the water out as explained above (if necessary, repeat this procedure several times).

• If the shut-off valve is removed, the pump can be flushed quickly. Improper spray distribution is the result of a clogged nozzle, which is easily removed and cleaned.

• Soapandwatermayalsobeusedtocleantank.

• Do not use aggressive cleaning agents or

abrasives.

• Follow the recommendations of the chemical manufacturer for disposal of waste water and chemicals.

• Activated charcoal in liquid or other form may be

used to absorb chemicals in tanks or spills.

NOTE: When cleaning the sprayer after working with hormone weedkillers, follow the instructions of the herbicide producers. Neutralize with activated charcoal. (Example: add 0.35 oz./1 g. of activated charcoal to 1.7 pint/1 liter of water and leave this detergent in the tank and the lines approximately for 24 hours.) This is very important if other chemicals should be sprayed as the residues of the herbicide may damage susceptible plants. Cleaning after application of products containing carbolineum, if they are not water soluble, should be done with a 5% soda lye having a temperature of 104°F (40°C). Rinse with plenty of clean water.

maintenance and stoRage tips:

To protect the piston, cylinder and Viton® collar, a fine mesh, stainless steel screen is located on the pressure cylinder inlet.

If you find that your sprayer will not empty the formula tank, check for a clogged inlet screen (2). The inlet screen is located at the bottom of the pressure cylinder on the side that faces your back.

One indication that it needs cleaning is that when you let go of the pump handle, it “springs” to the down position. The screen can be cleaned with a small bristle brush or a discarded toothbrush. See diagram for location of screen.

• After operation, the sprayer should be storedaway

from direct sunlight to prevent UV damage.

• After removing the pump or when mounting a new

Viton® collar, treat both the collar and the piston with water-resistant grease.*

• Before winter,drain all liquid in tank, lines and air chamber. (See “Cleaning.”) Leave shut-off valve locked in the “open” position.

• Forservice,visitourwebsitewww.hdhudson.comto

locate your nearest Hudson dealer. Always insist on original Hudson spare parts.

• Regularly inspect hose, wand, pump, tank and

shut-off valve for wear, damage or leaks. Repair promptly.

• Occasionallylubricatecapgasket.*

Avoid excessive wear by:

1) Regular lubrication of Viton® collar, cylinder and piston with water resistant grease.*

2) Prompt and thorough cleaning and flushing of sprayer. Soap and water work well.
