Operation
Filling the Reservoir From An External Source
The following procedure will fill the reservoir from an external fluid container.
The following figure shows the sequence of actions described in the procedure.
Note The fluid to be added must be a recommended type (see “Specifications
and Dimensions” on page 18) and the same as any fluid currently in the
Confining Pressure Intensifier. (Don’t mix fluid types.)
Preliminary steps A. Connect a filler hose between the connector on the lower side of the
Fluid Direction valve (rear side of control panel) and the external fluid
container. Immerse the container end of the hose in the fluid.
B. Connect a source of clean, compressed air to the quick-disconnect
connector on the Fluid Transfer Pump Control (rear of control panel).
Required pressure is 90 psi (0.6 MPa).
Procedure 1. Turn the Fluid Transfer Pump Control fully clockwise to the Off position.
2. Turn the Fluid Direction valve to position C.
3. Turn the Confining Fluid Input valve fully clockwise to the Close position.
4. Turn the Intensifier Fill valve fully clockwise to the Close position.
5. Set the Reservoir Fill valve a turn or two counterclockwise, in the Open
direction.
6. Actuate the air-driven hydraulic pump by rotating the Fluid Transfer Pump
Control counterclockwise.
7. Watch the fluid as it fills the reservoir. Set the Fluid Transfer Pump Control
to the Off position when fluid in the reservoir reaches the desired fill level
(typically three-quarters full).
8. Turn the Reservoir Fill valve fully clockwise (towards Close).
Note It might be desirable to fill the pressure intensifier from the same external
container, next. See “Filling the Pressure Intensifier From an External
Container” on page 30.
