sprayer components, even after the sprayer has been properly cleaned. These residual chemicals can have
unexpected effects on future uses. For example, spraying water or other liquids that are contaminated with residual
pesticide may result in unforeseen hazards to plant or animal life. This sprayer should not be used by people with
reduced physical, sensory or mental capabilities or lack of experience and knowledge.
