Avoid contact with chemicals.  \n4. Always wear rubber gloves, safety goggles and appropriate protective clothing.  \n5. Work in a well-ventilated area.  \n6. 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.  \nWARNING:  \nChemicals 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. Solo high density polyethylene sprayers are fitted with chemical resistant seals which are compatible to a wide variety of agricultural and household chemicals; 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 the manufacturer’s instructions or call the 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, GOGGLES, AND APPROPRIATE PROTECTIVE CLOTHING!  \n• Read and follow operating instructions.  \n• Do not fill with, use, or spray flammable materials, including Diesel Fuel.  \n• Do not modify sprayer.  \n• Never spray in the direction of humans, animals or property which might be injured or damaged by spray formula.  \n• Do not use disinfectants, solvents or impregnating agents unless first tested to ensure they are not harmful to the environment or sprayer.  \n• Do not use liquids with a temperature above 110°F (43°C) .  \n• Wear appropriate protective clothing to prevent contact with chemical agents.  \n• Rinse and clean sprayer thoroughly after using.
