6. Check for any leaks throughout the installation.
7. Remove front cover and locate the HI (13) and LO (14) pressure control
valves. They are factory set to deliver high pressure water at 3,100 bar
(45,000 psi) and 690 bar (10,000 psi). Turning clockwise increases
pressure, counterclockwise to decrease.
Note: If equipped with proportional pressure control, use the continuously
variable pressure control feature to adjust hydraulic and HP water pressure.
8. After the oil is warmed above 30°C (86°F), turn the HI pressure control
valve (13) counterclockwise all the way out, reducing the high pressure
setting to its minimum.
To assure proper oil viscosity and lubrication of the
hydraulic system, always operate the unit at a hydraulic oil
pressure of less than 70 bar (1,000 psi) until the oil
temperature is at least 30°C (86°F).
9. Set selector switch to HI pressure setting.
10. Open nozzle control valve, the intensifier assembly will start stroking
again. Turn HI pressure control valve (13) clockwise until reaching 1,034
bar (15,000 psi). Check for leaks.
