MAINTENANCE INSTRUCTIONS
Preventive Maintenance
The complete monitor and control system should be inspected during each apparatus check.
Careful inspection for damage to the monitor, valve or nozzle is especially important after use of
the COBRA™ EXM2 monitor in emergency operations.
• Operate all possible functions to ensure that each works normally
• Flow water to check the nozzle pattern
• If the pattern is disrupted, clear the debris
• If the obstruction still remains, remove the nozzle and check for debris lodged between the
nozzle stem and body
• During nozzle flow test, inspect monitor swivel joints and water valve for leaks
• Inspect all exposed wiring for signs of damage
Note: Grease fittings are provided for the up-down and left-right gear cases, routine greasing
should be done as dictated by the environment and usage. 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 EXM2 System. Using high
pressure spray can damage seals and lead to serious damage of electrical components.
