Solo 388 Contractor Industrial Sprayers Instruction Manual

WARRANTY:

Solo model 378 and 388 sprayers are covered by Solo’s 1-YEAR LIMITED WARRANTY. Solo manufactured parts which fail due to defective material or workmanship will be repaired or replaced without charge.

SAFETY PRECAUTIONS:

• Solo’s Contractor Industrial Sprayers are manufactured for specific chemical applications. Failures to use these sprayers for the purposes and with the chemicals intended could be harmful to the operator and cause the sprayer to fail.
• Before adding chemicals, fill the unit with clean water, pressurize and check for proper assembly and operation. CHECK PROPER OPERATION OF PRESSURE RELIEF VALVE PRIOR TO EACH USE!!
• Do not exceed 45 psi pressure.
• Observe the recommendations of the chemical manufacturer.
• Prior to removing any part of the sprayer pull the pressure relief valve to release any pressure in the tank.
• Wear rubber gloves, safety goggles and appropriate protective clothing.
• After pumping be sure handle is in the locked down position.
• Individuals should be trained in the proper use of this sprayer. 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 manufacturer’s instructions. Solo high density polyethylene sprayers are fitted with chemically resistant seals which are matched to the specific chemicals used in the Contractor- Industrial trades; however, care should be 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 manufacturer. If you suspect or observe indications that the material may be unsafe in a Solo sprayer… STOP! Do Not Use or Apply Chemical. ALWAYS WEAR RUBBER GLOVES, SAFETY GOGGLES

AND APPROPRIATE PROTECTIVE CLOTHING.

• Read and follow operating instructions.
• Do not fill sprayer over maximum fill mark. Releasing pressure in an overfill condition can cause harmful venting of sprayer contents.
• Relieve pressure only with sprayer upright and while standing on the side of the sprayer opposite the pressure relief valve. Venting of sprayer contents can occur if liquid is over bottom of relief valve.
• CAUTION: To prevent injury from ejected pump assembly and/or solution, never stand with face or body over the top of the tank when pumping, or loosening pump.
• Do not modify sprayer or pressure relief valve.
• Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula.
• Do not use liquids with a temperature above 120°F (45°C).
• Remember that a sprayer with liquid is a significant amount of weight (8 lbs. per gallon). Use caution when bending, leaning or walking. Bend only at the knees and support yourself as required to ensure personal safety.
• Do not inflate sprayer without liquid in the tank.
• Do not climb on ladders or other unsteady or potentially unsafe structures when operating your sprayer.

ASSEMBLY INSTRUCTIONS FOR WAND

1. Ensure that the O-ring is on the non-threaded end of the wand.
2. Insert the non-threaded end of the wand into the open end of the shut-off valve.
3. Tighten the screw cap

USING THE ADJUSTABLE NOZZLE

To change the spraying pattern, first make sure the retaining nut (2) is screwed tight to the elbow (5). If it is not tight, the nozzle cap (1) and nozzle body (3) will rotate inside the retaining nut and the nozzle will not adjust. For a straight stream pattern, rotate the nozzle cap outward. For a hollow cone pattern, rotate the nozzle cap inward towards the retaining nut.
If it becomes difficult to rotate the nozzle cap, remove the nozzle cap from the nozzle body and lubricate the O-ring on the nozzle body with a non-water- soluble grease*.

REMOVING ADJUSTABLE NOZZLE
Unscrew the nozzle cap (1) from the nozzle body (3). This is best accomplished while the retaining nut (2) is securely fastened to the elbow (5). Next, unscrew the retaining nut (2).
Push the nozzle body (3) out of the retaining nut (2). To reinstall the nozzle, reverse the above instructions.

OPERATION

• Before using sprayer with chemicals, fill sprayer with fresh water to assure that you have it properly assembled; pressurize and then practice spraying. When thoroughly familiar with sprayer operation, follow normal operating procedures.
• Turn pump handle counter clockwise to remove pump.
• Fill tank with premixed formula up to desired level. (Do not exceed maximum fill mark.) Observe recommendations of chemical manufacturer.
• Tighten cap and pump assembly for a good seal.
• Pump to a maximum 45 psi or 3 bar pressure. The valve stem on the pressure relief valve will rise up to vent excess pressure over 45 psi.
• Start or stop spraying by squeezing or releasing the lever on the shut-off valve. The spray pressure can be monitored with an optional pressure gauge.
• Prior to every removal of pump, release pressure first by pulling up on the pressure relief valve stem.

CLEANING

• Carefully clean sprayer after every use.
• Pour or spray all remaining chemical out of sprayer
• Pour a small amount of water for water soluble chemicals, or mineral spirits for oil-based chemicals, into the tank.
• Pressurize and spray through system until all liquid is gone.
• Repeat process with warm soapy water.
• Repeat process with warm clear water.
• Use an absorbent cloth to dry all internal surfaces.
• Follow the recommendations of the chemical manufacturer for disposing of waste water and chemicals.
• Do not use aggressive or abrasive cleaning agents.

MAINTENANCE

• Prior to storage, empty, clean and dry sprayer.

• Always store the sprayer in a dry area, protected from freezing, heat and sunlight.

• Lubricate O-ring in pressure relief valve with nonwater-soluble grease (Silicone grease for model 388) on a regular basis.
  Disassembly: Unscrew pressure relief valve from tank and pull the valve body out of the screw cap. Clean, lubricate, and replace.

• Pump Maintenance: Pump pressure sealing is accomplished with an O ring (5) on the pump piston (4) which moves within the cylinder (3). Periodically this O-ring should be greased with a non-water-soluble grease (Silicone Grease for model 388). If worn, it should be replaced. A small umbrella valve (6) at the bottom of the cylinder prevents the formula from entering the cylinder. Keep these parts clean and replace if worn.
  Disassembly: Unscrew pump assembly from tank. Carefully remove umbrella valve (6) from the bottom of cylinder (3). While holding cylinder firmly with one hand and the handle of the pump piston (4) firmly in the other, with the piston fully inserted in the cylinder, pull back on the piston quickly and forcefully. To re-assemble, place the piston assembly back into cylinder, place heel of hands on opposite sides of the tank cap, while keeping cylinder in place with fingers, tap bottom of cylinder against a flat padded surface. Assembly will lock into place.
  

• Tank Cap: A small amount of non-water-soluble grease (Silicone Grease for model 388) on tank cap threads and the gasket eases tightening and loosening.

• Regular Inspection: Inspect and replace worn or damaged parts promptly. Pay particular attention to tank cap gasket, pressure relief valve and seal, inflation valve (if fitted), umbrella valve, O-rings and seals throughout sprayer. Regular lubrication of O-rings and seals is recommended. (Silicone Grease for model 388).
