CHAPTER 4 - MAINTENANCE INSTRUCTIONS
4-1 INTRODUCTION
The HydroBlast System must be inspected, tested and maintained in accordance with the
inspection, testing and maintenance schedule mandated by the Authority Having Jurisdiction.
Follow the required inspection, testing, and maintenance procedures for the associated plant/
remote control unit as directed by the manufacturer and by the standards and codes that
apply to those systems.
4-2 PREVENTIVE MAINTENANCE
The complete monitor and control system should be inspected during each scheduled
inspection. Careful inspection for damage to the monitor and nozzle is especially important
after use of the HydroBlast system in wash 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 for leaks
• Inspect all exposed wiring for signs of damage
• If protective cage is used, use the appropriate tool to clean the cage of dust build up
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 HydroBlast System.
Using high pressure spray can damage seals and lead to serious damage of
electrical components.
