6.0 OSC OSCILLATING UNIT
An automatic oscillating mechanism is available for the BlitzForce Monitor. The BlitzForce Monitor can be purchased with the
oscillating mechanism factory installed or added at the factory later.
6.1 SAFETY - OSCILLATOR
DANGER
Do not attempt to modify this oscillating mechanism to fi t any other monitor. To do so will cause
the reaction force of the nozzle to be unaligned with the center of rotation. The monitor may spin
very fast with a very high force.
WARNING
Keep hands and fi ngers away from the moving parts of the oscillating unit when water is fl owing.
There are moving parts that can pinch fi ngers and hands.
WARNING
Make sure the BlitzForce is on a fi rm surface with adequate holding power. As the nozzle goes
back and forth, the reaction force is acting in diff erent directions on the leg spikes. Surfaces such
as asphalt, turf and dirt generally have good holding power. Surfaces like concrete and loose
gravel hold poorly.
CAUTION
Because the nozzle attached to the BlitzForce 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.
6.2 GENERAL - OSCILLATOR
The BlitzForce oscillating mechanism can be used for exposure protection, cooling, or any other situation where it is desirable to
have a monitor sweep back and forth.
The oscillating mechanism is driven by a turbine wheel. A worm gear drive reduces the speed and increases the torque of the
turbine wheel. A simple crank mechanism makes the outlet of the BlitzForce and the nozzle attached to it move back and forth. The
horizontal sweep can be set for a 20, 30 and 40 degree sweep. The oscillating mechanism can be uncoupled and the water stream
can be aimed manually.
The speed of oscillation is a function of fl ow rate, see the BlitzForce Oscillation Speed graph on page 10. A minimum fl ow rate of 175
GPM is required for proper oscillator operation.
6.3 OSCILLATOR
Operating details for the BlitzForce Oscillator are shown in fi gure 6.3.
The BlitzForce’s oscillator is protected by a shock absorber system. If the nozzle encounters an obstruction the shock absorber will
compress or extend as needed to protect the gears from overload.
