IV. Maintenance
1. Monitor should be inspected on a monthly basis.
2. Careful inspection should be conducted after use during emergency operations.
3. Exercise monitor by moving it thru its entire range of motion once a month to assure that
monitor is operating properly, preferably with water flowing at the rated volume and pressure.

compound MIL-SC-8660B or equal) should be maintained on gears, especially in corrosive
environments or in freezing temperatures.

expelled. Use a good grade waterproof grease. Wipe off expelled grease.
6. Flow test to check nozzle stream performance. If pattern is disrupted, remove nozzle and
stream shaper (if provided) and check for debris lodged in nozzle or stream shaper inlet
7. During nozzle flow test, inspect monitor swivel joints for leaks
8. Maintain paint as dictated by environment conditions.
