When a flexible whip is used to allow cutting nozzle movement, anti-vibration fittings and proper
supports and guides must be provided to prevent failures from non-water related stresses. The
whip will only flex in a single plane without being subjected to torsional stress. The use of high
pressure swivels is strongly recommended.

2.9 Commissioning
When the machine has been positioned, all service connections installed, and the high pressure
plumbing has been installed to the cutting area, the machine is ready to be commissioned.
The following procedure is used for the initial startup and testing of the machine.
1. Check all areas in and around the pump for foreign objects and debris. Remove all tools,
parts, etc. from the area.
2. Check the hydraulic fluid level. The hydraulic system is pre-filled prior to shipping. If
the hydraulic fluid is low or empty due to leakage during transit, the system must be filled.
Follow the instructions and specifications in Section 5, Recirculation System.
3. Open the shutoff valves on the service connections and check for leaks.
4. Check the connection between the customer supplied, main power disconnect. Verify the
proper voltage supply. Turn the control power on and select low pressure operation.
5. To avoid a sudden increase in pressure, it is necessary to adjust the high pressure setting.
The high pressure adjustment is made at the high pressure control valve on the hydraulic
manifold. Refer to Section 6, Hydraulic System, for additional information.
Loosen the locking nut on the high pressure control valve by turning counter-clockwise.
Turn the high pressure control valve counter-clockwise, decreasing the pressure to the
lowest setting.
