NSPECTION
The monitor should be inspected regularly. Careful inspection for damage to
the monitor or nozzle is especially important after use in emergency
operations.
Flow water to check nozzle pattern. If pattern is disrupted, remove nozzle and
check for debris lodged between the nozzle stem and body, or in the stream
shaper inlet.
During nozzle flow test, inspect monitor swivel joints for leaks.
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.
