To reduce the risk of overpressurizing your system,
which could cause component rupture and serious
injury, follow these precautions:
• Never exceed 1900 psi (13.1 MPa, 131 bar)
hydraulic input to the motor.
• Never exceed the maximum fluid working
pressure of 3000 psi (20.7 MPa, 207 bar) for
low-pressure models or 4300 psi (29.6 MPa,
296 bar) for high-pressure models.
• When starting the hydraulic system, open the
return line shutoff valve (N) first, then open the
hydraulic supply line valve (M).
Pressure Relief Relief Procedure Procedure
Pressure Pressure Relief Procedure
Follow the Pressure Relief Procedure
whenever you see this symbol.
This equipment stays pressurized until pressure is
relieved manually. To help prevent serious injury
from moving parts or from pressurized fluid, such
as skin injection or splashing in the eyes or on
skin, follow the Pressure Relief Procedure when
you stop pumping and before you clean, check, or
service the equipment.

1. Engage the gun trigger lock.
2. Close the hydraulic supply shutoff valve (M).
3. Disengage the gun trigger lock.
4. Hold a metal part of the gun firmly to the side of a
grounded metal pail. Trigger to relieve pressure.
5. If you suspect the spray tip or hose is clogged or
that pressure has not been fully relieved:
a. VERY SLOWLY loosen the hose end
coupling to relieve pressure gradually.
b. Loosen the coupling completely.
c. Clear hose or tip obstruction.
6. When all pressure is relieved, close the hydraulic
return shutoff valve (N).
