What should be done if there is a significant change in the length of the hose?

When there's a significant change in the length of the hose, recalibrating the equipment is important because the change in hose length can affect the pressure and flow rate of the substance being delivered. Equipment like sprayers or applicators are calibrated to work under specific conditions, including the dimensions of the hose used. With an altered hose length, the existing settings might not deliver the intended amount of pesticide or other materials accurately, leading to ineffective treatment or potential over-application. Recalibrating ensures that the equipment adjusts to the new parameters, maintaining accuracy and safety in application, which is crucial in pest management practices where precision is key.
