5.2.4 TO DISENGAGE THE OSCILLATING MECHANISM
To operate the oscillating monitor manually, pull then twist the black knob located on the side of the monitor. Twisting will lock the knob in
the disengaged position. The crank, rod, and spring canister will continue to move. Move the nozzle to the desired position by hand.
5.2.5 COVERAGE AREA OF THE OSCILLATING MONITOR
To adjust the area of coverage, refer to figure 6.3. Engage the oscillating mechanism once the desired angle has been set.
Oscillation speed: The chart shows how many times per minute the
oscillator makes one complete cycle as a function of flow. The higher the
flow, the faster it oscillates.
Nozzle reach: Refer to the operating manual for the specific nozzle. For
reach with oscillation, subtract 20% from the distance.
Figure 5.2
CAUTION
Because the nozzle attached to the oscillator must slow down, stop and reverse direction at the end
of each sweep, the ends of the covered area will receive more water than the center. If the center
area of coverage needs the most cooling, occasionally narrow the area of coverage or use the
oscillator manually.
NOTICE
The type of nozzle and flow pressure are critical to the coverage area. The graph shows coverage
area based on the movement capability of the oscillating mechanism. Actual coverage will depend
on flow, pressure, type of nozzle, angle of fog pattern, and wind conditions.
