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 pressurized fluid, such as 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.

Shut off the air supply to the pump.

2.

Open the dispensing valve, if used.

3.

Open the fluid drain valve to relieve fluid
pressure. Have a container ready to catch the
drainage.
