NSPECTION
A. Monitor
1. Preventative 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.
a) Operate each function (left-right, up-down, stream-fog, stow) with each of the
transmitters.
b) Remove nozzle and check for debris lodged between the nozzle stem and body, or
in the stream shaper inlet. Remove debris.
c) During nozzle flow test, inspect monitor swivel joints for leaks.
d) With the water off, operate the stow function, looking for any possible
obstructions and check the final stow position.
e) 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.
Caution:
Always check stow position after any repairs to the monitor. It is possible
that during repair work stow position could be moved or lost and will need to be reprogrammed.
If necessary, reprogram stow position by following the instructions in Section V.D.
