2.3 PATTERN CONTROL
TFT's Industrial and Masterstream nozzles have full pattern control from straight stream to wide fog. Turning the stream shaper
clockwise (as seen from the operating position behind the nozzle) moves the shaper to the straight stream position. Turning the stream
shaper counterclockwise will result in an increasingly wider pattern.
Since the stream trim point varies with flow, the stream trim point should be "trimmed" after changing the flow to obtain the straightest
and farthest reaching stream. To properly trim a stream, first open the pattern to narrow fog. Then close the stream to parallel to give
maximum reach. Note: Turning the shaper further forward will cause stream crossover and reduce the effective reach of the nozzle.
Note: Models are also available with linear (push/pull), remote electric or hydraulic actuation of the stream shaper.

2.4 USE WITH FOAM
The Industrial and Masterstream nozzles may be used with foam solutions. Refer to fire service training for the proper use of foam.
For Class B fires, lack of foam or interruption in the foam stream can cause a break in the foam
blanket and greatly increase the risk of injury or death. Assure that:
Application rate is sufficient (see NFPA 11 or foam manufacturer's recommendations).
Enough concentrate is on hand to complete task (see NFPA for minimum duration time
requirements).
Foam logistics have been carefully planned. Allow for such things as:
Storage of foam in a location not exposed to the hazard it protects.
Personnel, equipment and technique to deliver foam at a rapid enough rate.
Removal of empty foam containers.
Keeping clear path to deliver foam as hoses, other equipment and vehicles are deployed.

Improper use of foam can result in injury or damage to the environment. Follow foam
manufacturer's instructions and fire service training to avoid:
Using wrong type of foam on a fire, i.e. Class A foam on a Class B fire.
Plunging foam into pools of burning liquid fuels.
Causing environmental damage.
Directing stream at personnel.

There is a wide variety of foam concentrates. Each user is responsible for verifying that any foam
concentrate chosen to be used with this unit has been tested to assure that the foam obtained is
suitable for the purpose intended.

2.4.1 FOAMJET LX WITH MASTERSTREAM NOZZLE
To increase the expansion ratio Task Force Tips "Foamjet LX" (model FJ-LX-M) may be used with the Masterstream nozzle. This low
expansion foam tube attaches and detaches quickly from the nozzle. Note: As expansion ratio is increased, the reach of the stream will
be decreased due to the greater amount of bubbles in the stream and their inability to penetrate the air. Generally, the reach with foam
is approximately 10 % less than with water only. Actual results will vary based on brand of foam, hardness of water, temperature, etc.
