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 of the Scorpion RF
monitor in emergency operations.
 Operate all possible functions to ensure that each works normally.
 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: 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 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. It is recommended that Mobilith AW2 grease be used to lubricate the
monitor gearing.
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 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, reprogram the stow position by following the
instructions in the Programming Stow Position section.
