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.
