8.0 OSC OSCILLATING UNIT
An automatic oscillating mechanism is available for the BLITZFIRE Monitor. The BLITZFIRE Monitor can be purchased with the
oscillating mechanism factory installed or added at the factory later.
8.1 SAFETY - OSCILLATOR
8.2 GENERAL - OSCILLATOR
The BLITZFIRE 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 BLITZFIRE and the nozzle attached to it move back and forth. The horizontal
sweep can be set for 20, 30, and 40 degree coverage. The oscillating mechanism can be uncoupled and the water stream can be aimed
manually.
The speed of oscillation is a function of flow rate, see the BLITZFIRE Oscillation Speed graph. A minimum flow rate of 175 gpm is
required for proper oscillator operation.
8.3 OPERATION - OSCILLATOR
The BLITZFIRE 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.

DANGER
Modifying this oscillating mechanism to fit any other monitor will cause the reaction force of the
nozzle to be unaligned with the center of rotation. An unaligned monitor may spin very fast with a
very high force, which can result in serious injury or death. Do not modify the oscillator to fit any
other monitor.
WARNING
When the oscillator is in operation, the reaction force is acting in different directions on the leg
spikes. These sudden changes in direction may cause the monitor to become off-balance resulting
in sliding or loss of control. Make sure the monitor is on a firm surface with adequate holding power
and properly tied off before operating the oscillator.
CAUTION
The oscillator unit contains moving parts that can pinch fingers and hands when the unit is in
operation. Keep hands and fingers away from the moving parts of the oscillating unit when water is
flowing.
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.
