5.4 ANCHORING BY TYING OFF

The safest method of restraining the monitor is to use a tie down strap. It is inherently more reliable than other methods since it does not
rely on traction or digging in of the spikes. It is also the safest method because, even if the monitor moves, its travel is limited by the
strap. A forward attachment point and a strap are provided with the Blitzfire. A loop on the end of the strap may be placed over the
anchor point or the strap may be wrapped around an object, such as a tree, and the snap end of the strap passed through the loop and
pulled tight. Keep the entire length of the strap as close to the ground as possible. Snap the hook into the hole in the front of the Blitzfire.
If the strap is too short to reach a suitable anchor, it may be extended with strong rope or chain. Keep the distance between the Blitzfire
and anchor as short as possible. Remove all slack between the Blitzfire and anchor before flowing water. Figure 4.3.3 shows the
elements of tying off the monitor.

6.0 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.

6.2 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. Like the standard Blizfire, the oscillator operates between 10 and 50 degrees above the
horizontal and 20 degrees either side of center. Flow and pressure ratings are the same as the standard Blitzfire. The oscillating
Blitzfire also has the same trip mechanism as the standard unit.
Figure 4.3.3 Tying Off of Blitzfire Monitor
Do not attempt to modify this oscillating mechanism to fit 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.
Keep hands and fingers away from the moving parts of the oscillating unit when water is flowing.
There are moving parts that can pinch fingers and hands. Keep the guard in place.
Make sure the Blitzfire is on a firm surface with adequate holding power. As the nozzle goes back
and forth, the reaction force is acting in different 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.
Because the nozzle attached to the Blitzfire 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.
