MAINTENANCE
3.1 Overview
The entire SL-V series has been designed to fail safely. Systems fail gradually; seals and
connections begin to leak slowly or suddenly through specially designed weep holes. Water or
oil dripping from a weep hole indicates internal seals or valves are beginning to fail, a warning
that maintenance will be required.
The comprehensive fault detection and troubleshooting logic built into the programmable logic
controller (PLC) monitors crucial pressure, temperature and fluid levels. Warning and shutdown
sensors guard against potential injury and equipment damage.
3.2 Maintenance
The waterjet system has been designed for ease of maintenance and long, reliable operation. In
order to keep the equipment in optimum operating condition, routine and preventive maintenance
is essential. Detailed maintenance and troubleshooting procedures for specific systems are
provided in subsequent sections of this manual.
Daily Inspection
The following inspection procedures should be performed each day. If problems are detected,
they should be remedied before placing the machine in service.

Prior to startup, inspect the area around the machine, the high pressure piping and
connections for indications of leaks.

Make sure there is no maintenance work in process.

Check the hydraulic oil level.

As the machine is started and water pressure increases, listen for unusual sounds.

Check for water or oil leakage.

Check the condition of the water filter and the oil filter.
Periodic Maintenance
A number of factors can contribute to component failure; poor water quality, operating
conditions, or improper maintenance procedures. Maintaining a service log can be a useful
method of tracking component life and maintenance trends. Analyzing service intervals will
assist in preparing a preventive maintenance schedule tailored to your specific application and
production requirements. Periodic maintenance, at regularly scheduled intervals, will minimize
unscheduled downtime and premature component failure.
Improper assembly can lead to the premature failure of components. Maintenance procedures
must be followed carefully; components must be properly cleaned prior to assembly and
tightened to the correct torque specifications.
