A. Preventive Monitor Maintenance
The complete monitor and control system should be inspected during each apparatus check.
Careful inspection for damage to the monitor or nozzle is especially important after use in
emergency operations.
¾ Operate each function (left-right, up-down, stream-fog, stow) with each of the
controllers.
¾ Remove nozzle and check for debris lodged between the nozzle stem and body, or in
the stream shaper inlet. Remove debris.
¾ During nozzle flow test, inspect monitor swivel joints for leaks.
¾ With the water off, operate the stow function, looking for any possible obstructions and
check the final stow position.
¾ Inspect all exposed wiring for signs of damage.
Note: Although grease fittings are provided for the up-down and left-right gear cases,
routine greasing should not be necessary. If the monitor is exposed to a high level of radiant
heat for a prolonged period, it may be possible for the factory grease to thin and run out of
the gear cases. In such an event, fresh grease should be applied.
B. Controller Circuit Board (81479000) LED’s
The circuit board within the 81480001 relay box has 18 LED’s to provide a comprehensive
guide in troubleshooting problems with the monitor control system.
