MAINTENANCE & INSPECTION
Monitor
Preventive 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, and after extended use in salt water environments.
Operate all possible functions to ensure that each works normally with each controller.
Flow water to check the nozzle pattern.
o
If the pattern is disrupted, remove the nozzle and check for debris lodged between the nozzle
stem and body, or in the stream shaper inlet. Remove debris.
During nozzle flow test, inspect monitor swivel joints for leaks.
With the water off, operate the stow function, looking for any possible obstructions and check
the final stow position.
Inspect all exposed wiring for signs of damage.
Note:
Grease fittings are provided for the up-down and left-right rotation joints, routine greasing
should be performed to expel water & other contaminants that can get into the rotation joints. 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 rotation joints. In such an event, fresh grease should be
applied. Use Mobilux EP2 or equivalent. Start at one end of travel range and apply grease through the
fitting of each joint until fresh grease comes out the joint. Repeat every 30 degrees throughout the full
range of travel on each rotation joint. Wipe off any expelled grease when done.
Caution:
DO NOT use high pressure spray to clean the monitor system. Using high
pressure spray can damage seals and lead to serious damage of electrical components.
Caution:
Always check the H2 travel limits and stow position after any repairs to the
monitor. It is possible that during repair work the stow position could be moved or lost,
and will need to be reprogrammed. If necessary, repeat Installation Step 4.
