What is a precaution when using automatic nozzles?

When using automatic nozzles, avoiding lubrication is crucial because these nozzles are designed to operate effectively without the need for any external lubricants. Lubricating them can lead to malfunctions or affect the internal mechanism, which relies on specific tolerances and friction levels to function properly. Excess lubrication can cause the nozzle to become sticky or fail to adjust pressure correctly, resulting in potential operational hazards.

Furthermore, the design of automatic nozzles typically incorporates materials that reduce friction naturally, ensuring they perform as intended. By keeping them free from additional lubricants, you maintain their efficiency and reliability while operating. Ensuring no extra substances compromise their functionality is vital for effective flow control during firefighting operations.
