Your Bumper 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 Bumper Monitor is misused in a manner that is inconsistent with standard
operating practices and those listed in IFSTA . A partial list of potential misuse includes:
• Operating above maximum rated pressure and flow.
• Not draining, and allowing water to freeze inside.
• Prolonged exposure to temperatures above 130°F, or below -25°F.
• Operating in a corrosive environment.
• Having the nozzle hit a fixed object during operating or transportation.
• 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 Bumper Monitor should be taken out of service, repaired, and tested by a qualified
technician before placing it back in service .
