Operation
Cooling mode on
Touch this symbol to turn ON the primary motor. The pump runs with the intensifier disabled. Hydraulic fluid 
circulates through the pump at minimum pressure, the cutting-water solenoid is open, and the boost pump is on.
Pressure mode
Touch these symbols to run the pump in pierce-pressure mode or cut-pressure mode.
Manual pressure adjustment
On a pump without a proportional control valve, use the pierce-pressure control knob and the cut-pressure 
control knob to adjust pressures manually. 
Turn the knobs clockwise to increase pressure. Turn the knobs anticlockwise to decrease pressure.
If the cut-pressure mode setpoint is less than the pierce-pressure mode setpoint, the pump operates at the 
lower pressure.
When turning off the pump, turn the cut-pressure control knob anticlockwise until it stops. This extends the life 
of the high-pressure seals and other high-pressure parts.
