protective clothing.

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. 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!
• Read and follow operating instructions.
• Do not fill with, use, or spray flammable materials, including Diesel Fuel.
• 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. For bleach solutions, try our Solo 475-B or 475-
B Deluxe sprayers.
• Remember that a sprayer with liquid is a significant amount of weight (8 lbs. per gallon). Do not climb when wearing
the sprayer. 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 assembly (#4800182) 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.
