PERATING INSTRUCTIONS
A. Normal Operation
1. 81498001 Joystick Transmitter
A. Monitor Control
With the 81498001 Joystick Transmitter, the monitor, nozzle, and valve are
controlled with the joystick and accompanying switches. Simply push and hold the
joystick to move the monitor to the desired stream direction. Release the joystick
when the proper stream position is achieved. The nozzle spray pattern is controlled
using the rocker switch on the top of the joystick. The controller provides an
automatic left-right speed adjustment to allow the user better directional control.
During normal operation, the left-right motor will move slowly for about two seconds
before accelerating to full speed. This allows the user to be able to position the
monitor quickly but also gives the fine control needed to aim the monitor accurately
at a distant target. Any combination of left or right and up or down can be used
simultaneously.
B. Valve Control
To flow water for short durations operate the valve with the trigger on the front of the
joystick. The valve will remain open as long as the trigger is squeezed. When it is
released, the valve will close. To continuously flow water, simultaneously push the
lock open pushbutton and squeeze the water valve trigger on the joy stick; once the
water valve starts moving the operator may release both switches and the valve will
travel to the full open position. To close the valve, push and release either the lock
open pushbutton or the water valve trigger on the joystick.
2. 81502001 Handheld Transmitter
The 8494 RF Monitor uses the standard Left/Right, Up/Down, and Fog/Stream
commands to provide stream direction and pattern adjustments. The transmitter provides
an automatic speed adjustment to allow the user better directional control. During normal
operation, the left-right motor will move slowly for about two seconds before accelerating
to full speed. This allows the user to be able to position the monitor quickly but also gives
the fine control needed to aim the monitor accurately at a distant target.
To move the monitor left or right, press and hold the left or right button until the monitor
discharge is in the correct position. The left-right motor will begin to turn the monitor
slowly and then accelerate to full speed after a couple of seconds. If any of the up-down
or fog-stream buttons are selected while the left-right motion is in slow speed, the left-
right motor will immediately go to high speed until the monitor stops moving. The unit will
revert to normal operation when the buttons are released.
1) To move the monitor up or down, press and hold the up or down button until the
monitor is in the correct position or an electrical stop is reached.
2) 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 end of travel will continue spinning until the button is released.
