VII MAINTENANCE
Inspection
1. Cycle nozzle through all functions (straight stream, fog, etc.) to confirm that it is fully functional.
2. Run the nozzle through its entire range of motion at least once a week
Maintenance (After each use or once per month)
1. Apply a thin coating of Dow Corning #7 silicone grease or equivalent to the surfaces that the nozzle
tip o-rings move across (See Illustration Below). Coat these surfaces with grease while the nozzle is in
the straight stream position (all the way forward).
2. Run the tip back and forth through its full range of motion several times to distribute the grease.
3. Stop the nozzle tip in the wide fog position (all the way back) and wipe off any excess grease.
VIII TROUBLESHOOTING
A. If nozzle stream cone is not tight and uniform; take nozzle and stream shaper off monitor and clean
debris out of both. Flush firewater lines with nozzle and stream shaper off monitor, then reassemble.
B. If nozzle will not move (to straight stream or fog); check electrical connection to make sure it is tight.
If the electrical connection is tight and nozzle still will not move, manually cycle nozzle three (3)
times, then try to move it electrically.
C. Check for power at nozzle connection.
Any problems that cannot be fixed/solved with this troubleshooting guide should be taken to your
Elkhart Brass Representative to get further information.
WARNING: Do not attempt to disconnect or work on any electrical equipment in this system
unless power is removed or the area is known to be non-hazardous.
