4.2 General Maintenance
Proper maintenance is important for reliable and consistent performance. Preventive
maintenance reduces unscheduled downtime, and extends component life.
High pressure water will cut almost anything it contacts.
Any leaks must be repaired immediately to prevent damage
or serious personal injury.
Stored hydraulic pressure can cause physical injury.
Should the unit be configured as a redundant intensifier,
before performing maintenance, all isolation hand valves
should be cycled after machine shutdown to vent to tank
any stored hydraulic pressure.
Maintenance Guidelines
• Regular inspection of equipment is recommended.
• Keep equipment and surrounding areas clean.
• Check pressures, temperatures, and look for leaks.
• Make repairs immediately.
• A maintenance record should be kept.
Work Area
• Maintain a clean work area for repair and maintenance of the waterjet
pump.
• Use a clean work bench in a dust and dirt free work area.
• Use lint-free material for wipe cloths.
• When blowing off parts with compressed air, use only clean, dry air. When
flushing parts with a solvent, use only clean, filtered fluid.
• Always use original Ingersoll-Rand replacement parts, for consistent
performance, reliability, safety, and to protect equipment warranty.
Safety Recommendations
• Carefully read the Safety Guidelines in Section 1, of this manual.
• Lock out all electrical power.
• Close all incoming supply valves and open all drain valves.
• Close the nozzle valves and manifold valves. When the power is shut off, the
safety dump valve will open and bleed off high pressure water stored in the
discharge piping.
• Provide suitable receptacles, pans, trays, etc. to catch and retain fluids to
avoid a hazardous work area.
• DOUBLE CHECK to insure that all pressure is relieved from the system
before proceeding.
