BEFORE USE
1. Before using this product, read the instruction manual completely
and familiarize yourself thoroughly with the product, its
components and recognize the hazards associated with its use.
2. Verify that the product and the application are compatible.
Inspect before each use. Do not use if bent, broken, leaking or
damaged components are noted.
3. Replace worn or damaged parts and assemblies with
BVA Hydraulics Authorized Replacement Parts only (See
Replacement Parts Section). Lubricate as instructed in
Maintenance Section.
4 Ensure method of confirming load is accurate and working
properly. Have gauge or load cell accuracy verified by qualified
personnel on a yearly basis.
5. Pumps should be stored where protected from the elements,
abrasive dust, and damage. Pumps can be stored horizontally
or vertically.
SET UP
WARNING:
The pump’s maximum working pressure is
7,200 PSI. Make sure that all hydraulic equipment such as
cylinders, hoses, couplers and etc. used with this pump are
rated at 7,200 PSI operating pressure or more.
1.
Set the pump on a hard flat surface, i.e. a work bench.
Remove
the oil filler screw found on rear end cap to check fluid level.
Correct fluid level is even with the oil filler screw hole.
2. Depressurize system by opening release valve counter-
clockwise, but no more than 2 full turns. Then carefully remove
the threaded plug on oil outlet port, and connect 1/4” NPTF
hydraulic connection to oil outlet port, i.e. coupler, gauge
adapter, hydraulic hose etc. Ensure all fluid ports and thread
connections are clean before connect.
NOTICE:
Always secure threaded connections with non-hardening
pipe thread compound. Take care not to introduce compound into
port orifices. Tighten securely to prevent accidental removal of
components while in use.
3. Install a pressure gauge in-line from the pump for better control
and safety purpose.
NOTICE:
It is recommended to use BVA fittings, gauge adapter
and guage.
4. Tighten securely to prevent accidental removal of components
while in use.
5. Check for leaks in system and repair by qualified personnel as
needed. Depressurize the hydraulic system before servicing.

OPERATION
WARNING: ALWAYS monitor pressure, load or position
using suitable equipment. Pressure may be monitored by
means of an optional manifold and gauge (contact BVA
Hydraulics). Load may be monitored by means of a load cell
and digital indicator. Correct application position can only be
determined by the operator of the equipment.
1. Remove the threaded plug, then connect the pump to suitable
application.
2. Ensure the oil level is correct and the system fittings and
connections are leak free before operating the pump.
3. Pump may be used in horizontal and vertical position as
illustrated in Figure 3.
CAUTION:
NEVER operate pump with release valve closed
and disconnected from application. If operated in this
condition, the hose and connections become pressurized.
This increases burst hazard. Damage may occur to pump
and its components
4. Close release valve by turning it clockwise. Finger tight ONLY.
Using tools on release valve can damage it and cause the pump
to malfunction.
5. Pump handle until desired pressure, load or position is reached.
6. Pressure will maintain until the release valve is opened.
7. To retract application, turn the release valve knob slowly
counterclockwise (never more that 2 full turns).
