II. Product Description

The Oscillating R.A.N. is designed to provide the firefighter the advantage of automatically oscillating

the discharge of the R.A.M. monitor in the horizontal direction. The Oscillating R.A.N. can be retro-

fitted to any R.A.M. monitor in a manner of minutes. The oscillator gives the firefighter the ability to

automatically sweep in any desired angle between 25 and 40 degrees. The automatic oscillation can

be simply disengaged for manual operation. The Oscillating R.A.N. can be quickly disconnected from

the R.A.M. monitor depending on the requirements of the situation. The Oscillating R.A.N. maintains

the same 500 GPM flow rating as the standard R.A.N. nozzle.

III. Support Bracket Installation

Important: Follow installation instructions to prevent damage to the monitor.

A. Pivot Bolt Removal

Remove the top and side pivot bolt from the R.A.M. monitor. This can be achieved with the

use of a 5/8” wrench. See Figure 1 below for pivot bolt location.

Figure 1: Pivot Bolt Removal

B. Bracket Installation

Install the support bracket with the supplied extended pivot bolts (Figure 2). This can also be achieved

with the use of a 5/8” wrench. Use Loctite #242 thread locker or equivalent on the pivot bolt threads.

Each bolt should be started before either bolt is completely tightened. Be sure to line up the blind

holes on the discharge ball joint and the double ball joint before tightening the bolts. Failure to

do so will result in damage to the monitor. In order to ensure the bolts are lined up with the blind

hole, move the discharge back and forth during the tightening of the pivot bolts. If the discharge will not

move left and right or up and down during the installation of the pivot bolts, loosen the pivot bolts and

realign the blind holes. See Figure 2 and Figure 3 for support bracket location.
