What characteristic should operators maintain while using mist blowers?

Maintaining equipment cleanliness and functionality is crucial for the safe and effective use of mist blowers. A clean machine ensures that the application of pesticides is consistent and that blockages that may lead to uneven application or spills are minimized. Regularly checking for functionality helps prevent accidents and ensures that the mist blower operates as intended, providing the correct dosage of pesticide to the intended area.

While other factors, such as avoiding windy conditions and minimizing exposure to sunlight, are essential for safety and efficacy, they pertain more to environmental considerations rather than the machinery itself. Additionally, the use of solvents is important, but it's the maintenance of the equipment that directly influences the performance and safety of pesticide application.
