What is the first step to take when cleaning a clogged nozzle on a sprayer?

When dealing with a clogged nozzle on a sprayer, the first step should be to stop the sprayer. This is essential for safety reasons; continuing to spray while dealing with a clog can lead to unintended pesticide application, which may cause harm to the environment, the user, or others nearby. Stopping the sprayer ensures that it is safe to inspect and clean the nozzle without risk of accidental spraying.

After stopping the sprayer, the operator can assess the situation, identify the clog, and take appropriate measures to resolve the issue, whether that involves cleaning the nozzle, checking filters, or using solvents. The focus should always be on safety and proper handling of equipment before attempting repairs or maintenance.
