7.0 OSCILLATION UNIT GENERAL INFORMATION
An automatic oscillating mechanism is available for the Blitzfi re Monitor. The Blitzfi re Monitor can be purchased with the oscillating
mechanism factory installed or added at the factory later.
7.1 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 Blitzfi re 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 Blitzfi re 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.
CAUTION
Because the oscillating mechanism is always moving, the monitor should be manned at all times.
When oscillation is disengaged, be prepared for unintended movement of the nozzle.
7.2 VARIOUS MODELS AND TERMS – OSCILLATOR
The Blitzfi re 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 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 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 Blitzfi re 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.
7.3 OPERATION – OSCILLATOR
Operating details for the Blitzfi re Oscillator are shown in fi gure 7.3.
The Blitzfi re 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.
