MAINTENANCE INSTRUCTIONS
Your StreamMaster monitor and nozzle should be inspected prior to and after each use to ensure it is in
good operating condition. Periodically, an unanticipated incident occurs where the unit is misused in a
manner that is inconsistent with standard operating practices. A partial list of potential misuses includes:
• Operating above the maximum rated pressure or flow.
• Prolonged exposure to temperatures above 130°F, or below -25°F.
• Operating in a corrosive environment.
• Having the StreamMaster nozzle hit a fixed object during operation or transportation.
• Any other misuse that might be unique to your specific environment.
Also, there are many “tell tale” signs that indicate repair is in order, such as:
• Controls that are either inoperable or difficult to operate.
• Excessive wear
• Poor discharge performance
• Water leaks.
If any of the above situations are encountered, the StreamMaster monitor should be taken out of service,
repaired, and tested by a qualified technician before placing back in service.
