Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever
you see this symbol.
This equipment stays pressurized until pressure is
manually relieved. To help prevent serious injury from
pressurized fluid, such as skin injection, splashing
fluid and moving parts, follow the Pressure Relief Pro-
cedure when you stop dispensing and before clean-
ing, checking, or servicing the equipment.
To relieve pressure:
1. Turn off main power to the motor.
After the power is turned off, the pressure will drop
partially, through the gears. This depends on the oil
viscosity, valves and gears.
2. The remaining pressure will be relieved through the
3-way valve installed in the outlet tubing.
