and attach it to the portable base. Attach the upper monitor assembly to the
portable base using the same technique used to attach it to the deck mount
adapter (see section VI.A.1).
5. Confirm correct latch pin engagement by checking visual indicator cut outs in
latch pin caps (See Figure 16).
6. Aim the monitor nozzle towards the intended target. The monitor discharge
should not be turned more than 45 degrees to either side of the front leg
bracket.
7. Charge the hose lines slowly to prevent water hammer.
8. Operate the monitor as described in section VI.A.1, deck gun operation. (See
Warning below).
9. To lower the discharge below 30 degrees, simultaneously press and hold the
“down” button and the “aux 2” button on the transmitter. Once the desired
position is attained, release the down button. The aux 2 button must be
continually depressed in order to sustain this position. If the aux 2 button is
released, the monitor will automatically return to the safe 30-degree elevation
position. As soon as the nozzle elevation is raised above 30 degrees the
up/down electronic stop will re-engage itself and need to be over-ridden again
to go below 30 degrees elevation.
Warning:
Use extreme caution when lowering the discharge elbow below the angle allowed by the
up/down electronic stop when flowing the Stinger RF
® in portable mode. If the discharge
is lowered below the electronic stop, the nozzle reaction force may cause the monitor and
hose lines to slide. If the discharge is lowered below horizontal, the nozzle reaction force
will cause the monitor and hose lines to become airborne. Serious injury or death could
occur if these warnings are not followed.
C. Normal Operation
The 8297 RF Monitor uses the standard Left/Right, Up/Down, and Fog/Stream
commands to provide stream direction and pattern adjustments.
To move the monitor left or right, press and hold the left or right button until the monitor
discharge is in the correct position or a programmed limit is reached. To move the
monitor “up” or “down,” press and hold the up or down button until the monitor is in the
correct position or the electronic stop is reached. To adjust the stream pattern, press and
hold the fog or stream button until the desired stream pattern is reached. Elkhart electric
nozzles have a unique ball screw drive which when it reaches the extents of travel will
continue spinning until the button is released.
