14. Press 1 on the numeric keypad to change to pierce-pressure mode.
15. To clear air from the high-pressure lines, turn ON the cutting head. When water comes out of the cutting head, turn it
OFF.

When the cutting head is turned on, the intensifier strokes.

The pump is on standby when the cutting head is turned off. Hydraulic pressure remains at the set pressure and
the intensifier does not stroke.
16. Slowly turn the control knob to the right (clockwise) to increase the pressure.
Flush the pump and the high-pressure tubing
Follow this procedure after replacing or repairing high-pressure tubing and fittings.
It is common for small pieces of metal and debris to be present in newly installed high-pressure tubing. Flush the system
to prevent damage to orifices, on/off valve parts, and other parts of the high-pressure system.

This procedure identifies 1 method to flush out the high-pressure lines. If this pump was purchased through an OEM,
the OEM might have a recommended procedure.

This procedure can cause damage to the on/off valve sealing parts and orifices. Keep spare kits and orifices available.
1. Press F2 to turn on the pump in cooling mode. The cutting water solenoid opens and the hoses fill with low-pressure
water.

The intensifier does not stroke.
2. Turn the pierce-pressure adjustment knob to the left (anticlockwise) to decrease the pierce pressure.
3. Make sure that the hydraulic pressure is 34 bar or 3,447 kPa (500 psi) or lower. If the pressure is higher
than 34.5 bar or 3,447 kPa (500 psi), contact Hypertherm Technical Service for support.
4. Remove the cutting head and the orifice.
5. Press 1 on the numeric keypad to change the pump to cut-pressure mode. (Refer to the Pump running screen on
page 53.) The intensifier should stroke until the pump reaches the high-pressure setting and stop stroking.
Two gauge symbols are shown on the screen. If the gauge symbol on the right (cut pressure) is blinking, press 1 on
the numeric keypad to switch to the pierce-pressure gauge symbol.
6. Use the CNC control to make a program that turns the valve ON and OFF in 1-second increments. Run the program
in a loop for 15 minutes.
WARNING
Use a piece of cardboard or other solid material to check for leaks when the pump is on. Do not use
hands, cloth, paper, or towels.
WARNING
Do not attempt to repair a leak with pressure in the system.
