VII. Stream Pattern Adjustment
The stream pattern on the Oscillating R.A.N. can be adjusted from wide fog to straight stream by
rotating the nozzle tip. Rotating the tip to the right will adjust the nozzle into the straight stream
position. In order to achieve a wide fog pattern, the nozzle tip will need to be rotated to the left. Do
not attempt to adjust the stream pattern while the automatic oscillation is engaged. Move the
engagement lever to the manual position before attempting to adjust the stream pattern.
VIII. Maintenance
A. Maintenance After Use
The Oscillating R.A.N. has been designed and manufactured to provide years of trouble free
service. After each use, the waterway should be flushed and visually inspected for debris. This
can be done by flowing a clean water source through the nozzle. If there is any debris in the
waterway, it should be removed before the next use to ensure proper performance of the
nozzle. The paddle wheel should be rotated by hand to ensure that the nozzle is functioning
correctly.
B. Inspections
Weekly visual inspections and monthly operational checks will promote proper nozzle function.
These inspections should be done daily in busy companies.
C. Storage
To prevent possible freeze damage, be sure the Oscillating R.A.N. is thoroughly drained after
use. The nozzle may be stored on the R.A.M. monitor if desired.
