When the handle is in position "B", and piece "D" is in place, the device shown in the illustration will produce __________. See illustration SF-0011.
• Operation of an all-purpose fire nozzle (bale/handle positions for OFF, solid stream, and fog) • Function of piece D (the spray tip/deflector) versus piece E (fog applicator tube) • Difference between high velocity fog and low velocity fog and what attachment is required for each
• In position B, is the bale (handle) opened part‑way, fully open, or fully closed to water flow through the nozzle body? • With piece D installed but no additional attachment on point E, will the water exit as an unobstructed stream or be broken up immediately at the nozzle tip? • Which type of fog, high or low velocity, depends on whether a separate applicator tube is attached, or only the spray tip is in place?
• Identify which handle position (A, B, or C) is OFF and which gives solid stream when piece D is removed • Confirm whether any applicator tube is shown attached at point E in the illustration • Recall that low velocity fog on an all‑purpose nozzle normally requires an added applicator, while high velocity fog is produced directly at the spray tip
