APPLICATION Task Force Tips automatic and smooth bore nozzles are used by the Department to flow water from hand lines. OPERATIONAL POLICY This section intentionally left blank. OPERATIONAL GUIDELINE Members operating the Task Force Tips nozzles should be familiar with the basic operation and flow capabilities of each nozzle. For recommended pump discharge pressures, refer to Training and Equipment Manual, Section 303.005, Pump Operator’s Guide. PROCESS The valve handle operates the slide valve or ball shutoff portion of the nozzle. The valve handle has detented flow positions. These detent positions allow the nozzle operator to regulate the flow of the nozzle depending on the situational need. 1. How the valve handle operates: • Pull back on the valve handle to open. • Push forward on the valve handle to close. • Close valve handles slowly to prevent water hammer.

The nozzle has a full pattern control from straight to wide fog as follows: • Turning the stream shaper clockwise (as seen from the operating position behind the nozzle) moves the shaper to the straight stream position. • Turning the shaper counterclockwise results in an increasingly wider pattern. Since the stream trim point varies with flow, the stream can be “trimmed” after changing the flow to obtain the straightest and farthest-reaching stream. Properly trim the stream as follows: 1. Open the pattern to narrow fog. 2. Close the stream to parallel to give maximum reach. If equipped with a debris screen, small debris pass through the screen and may become trapped inside the nozzle. This trapped material can cause poor stream quality. The nozzle can be flushed by using the following steps: • Rotating the shaper counterclockwise to the flush position while still flowing. This opens the nozzle allowing debris to pass through. . • Rotating the shaper out of flush to continue normal operations.
