9. Install the high pressure cylinder assemblies into the hydraulic cylinder heads, following
the procedure, High Pressure Cylinder Assembly Installation.
10. Connect the high and low pressure water piping. And turn the low pressure water supply
on.
9.13 Hydraulic Cylinder Maintenance
The inside diameter surface of the hydraulic cylinder should be inspected for wear grooves and
surface finish whenever the hydraulic cylinder heads are removed. Excessive grooving is
indicative of piston seal wear.
9.14 High Pressure Attenuator
The high pressure attenuator is not serviceable at the customer level. KMT Waterjet Systems
tests the seals in the attenuator at pressures exceeding normal operating pressure, making
disassembly difficult. If the attenuator develops a high pressure water leak, it should be replaced.
