Pivoting Inlet; Outlet Pivots; Elevation Holding Mechanism; Flows And Pressures - Task Force Tips BLITZFIRE Series Instructions For Safe Operation And Maintenance

2.4 PIVOTING INLET

The Blitzfire has a pivoting inlet so that different size hoses can be used without lifting the spikes off the ground. The pivoting inlet also
allows the monitor to be positioned on porches, stair landings, and the like. The pivot moves up and down 20 degrees. The Blitzfire is
equipped with three spikes to provide traction when flowing from the ground. For the spikes to provide traction they must remain in
contact with the ground. Assure that the hose is not on top of anything that would cause the spikes to lift off the ground. Figure 2.5
shows the inlet pivot's range of motion.

2.5 OUTLET PIVOTS

The Blitzfire's outlet pivots allow for 20 degrees of motion either side of center and elevation between 10 and 50 degrees from
horizontal. Push or pull on the nozzle to redirect the stream. The pivots are easy to reposition under pressure and are good for rapid
redirecting of the stream. However, if the pivot is rapidly bumped against its travel limit, the Safety Shut-Off Valve may activate and shut
off the monitor. Figure 2.5 shows the outlet pivots range of motion.
The Blitzfire has been designed to operate at very low elevation angles to maximize usefulness for interior attack. As with any monitor,
when the elevation angle is low the risk of sliding is increased. This is because at low elevation angles the reaction force is more
horizontal and less vertical.
Elevation drag adjusting nut.
Tighten to increase drag. Loosen to
decrease drag. Do not exceed 200 in-lb
(22 N-M) of holding torque.

2.5.1 ELEVATION HOLDING MECHANISM

The elevation pivot has a mechanism to support the weight of a nozzle. It is factory set to support the weight of nozzles likely to be used.
It may be adjusted (see figure 2.5). The mechanism releases when raising the nozzle so upwards drag from the mechanism is not felt.
Avoid the use of long stream straighteners or heavy nozzles which may overcome the holding torque of the elevation mechanism.

3.0 FLOWS AND PRESSURES

The Blitzfire Portable Monitor is designed for maximum flows of 500 GPM (2000 LPM) and a maximum pressure of 175 PSI (12 BAR). Do
not exceed these limits.
WARNING

3.1 AUTOMATIC, FIXED, AND SELECTABLE FLOW NOZZLES

A variety of water or foam nozzles may be used with the Blitzfire.
Automatic nozzles maintain a constant pressure by adjusting their opening to match the available flow. Consult the nozzle
manufacturer for maximum flow and pressure ratings. In all cases do not exceed 500 GPM (2000 LPM) and/or 175 PSI (12 BAR).

An inadequate supply of pressure and/or flow will cause an ineffective stream and can result in
injury, death or loss of property.
