5.2 PATTERN AND FLUSH CONTROL

TFT’s 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 shaper counterclockwise will result in an increasingly
wider pattern.
Since the stream trim point varies with fl ow, the stream
should be “trimmed” after changing the fl ow to obtain the
straightest and farthest reaching stream. To properly trim
the stream, fi rst 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 eff ective reach of the nozzle.
The nozzle reaction is greatest when the shaper is in
the straight stream position. The nozzle operator must
be prepared for a change in reaction as the pattern is
changed.
Care must be taken to avoid dents or nicks in the nozzle tip
because they can seriously aff ect the stream reach.
5.2.2 SHAPER TACTILE INDICATOR
The G-Force has a tactile indicator on the stream shaper.
The tactile indicator allows the stream shaper position (and
fog angle) to be determined by feel rather than by sight.
The fog angle can be adjusted (see section 5.2.4) so that
a desired fog angle is achieved when the tactile indicator
in on top of the nozzle. The G-Force has an optional detent
to aid in returning to a known fog angle. Note: The fog
angle will change as fl ow and pressure change (becoming
wider with increased fl ow).
