This equipment stays pressurized until pressure
is manually relieved. To help prevent serious
injury from pressurized fluid, such as splashing
in the eyes or on skin, follow the Pressure

Procedure
Procedure
Procedure when you stop pumping and before you
clean, check, or service the equipment.
1.
Shut off the power to the pump.
• In a hydraulic system, close the hydraulic
shutoff valves.
• In an air-powered system, close the pump air
regulator, and close the bleed-type master air
valve (required in your system).
2.
Close the fluid shutoff valves from the supply
tanks.
3.
Hold a metal part of the gun (if used) to a
grounded metal pail. Trigger the gun to relieve
the pressure.
4.
Open the fluid drain valve (required in your
system), having a container ready to catch the
drainage. Keep hands away from the end of the
drain valve when opening it.
5.
Leave the drain valve open until you are ready
to return to operation.
6.
Close the bleed type air valve that is connected
to the inlet of the surge suppressor.
7.
To relieve the air pressure in the surge
suppressor, ensure that you have relieved
the fluid pressure. The surge suppressor will
automatically relieve and exhaust air from its
chamber

2.
Always re-torque all of the cap screws using
a star-pattern sequence before you operate
the surge suppressor to ensure against fluid
or gas leakage. For torque specifications, see
3.
Open the air valve to the suppressor. When the
fluid pressure is high enough, the poppet valves
trigger, injecting air into the suppressor until it is
balanced.
NOTE: The maximum fluid working pressure for
the surge suppressor is 350 psi (2.4 MPa, 24
bar). Do not exceed the fluid line pressure or the
associated suppressor air pressure.
