PRODUCT DESCRIPTION
BVA Hydraulic Hand Pumps are engineered to meet most industrial standards for performance and safety. These pumps have
a unique two-stage hydraulic circuit allows quick displacement of hydraulic fluid under no load conditions and easy pumping in
loaded conditions. These lever operated pumps supply compressed hydraulic fluid to compatible applications i.e. rams, presses,
spreaders, compactors and crimping machines, anywhere that 10,000 PSI of fluid pressure is needed. Special skill, knowledge
and training may be required for a specific task and the product may not be suitable for all the jobs described above. Unsuitable
applications would include applications that call for a device to move, level or support persons, animals, hazardous materials,
mobile homes/ dwellings in general, mirrors and/or plate glass, and/or to connect/secure hatches, components, etc. between
bulkheads. The user must ultimately make the decision regarding suitability of the product for any given task and assume the
responsibility of safety for himself/ herself and others in the work area.
Always check connections before using. Alteration of these products is strictly prohibited. Use only those adapters and
attachments provided and approved by the manufacturer.
WARNING: To reduce the risk of personal injury and/or property damage, ensure that the rated working pressure of each
pressurized attachment be equal to or greater than the rated working pressure developed by the hydraulic pump.

• Study, understand, and follow all
instructions provided with and on this
device before use.
• All WARNING statements must be
carefully observed to help prevent
personal injury.
• No alteration shall be made to this
device.
• Always wear protective gear when
operating hydraulic equipment.
• Keep hydraulic equipment away from
flames and heat. Hydraulic fluid can
ignite and burn. Do not operate if
leaks are detected.
• Crush Hazard. Keep hands and feet
away from loading area. Avoid pinch
points or crush points that can be
created by the load, cylinder, or any
equipment of system.
• To avoid crushing and related injuries:
NEVER work on, under or around
a lifted load before it is properly
supported by appropriate mechanical
means. Never rely on hydraulic
pressure alone to support load.
! WARNING
HYDRAULIC PUMPS
• The user must be a qualified operator familiar with the
correct operation, maintenance, and use of pumps. Lack of
knowledge in any of these areas can lead to personal injury.
• Do not exceed rated capacity of the pump or any equipment
in the system.
• Never attempt to lift a load weighing more than the capacity
of the cylinder.
• Burst hazard exists if hose or connection pressure exceeds
rated pressure.
• Inspect pump, cylinder, hoses and connections before each
use to prevent unsafe conditions from developing. Do not
use if they are damaged, altered or in poor condition. Do
not operate the system with bent or damaged coupler or
damaged threads.
• Never hold or stand directly in line with any hydraulic
connections while pressurizing.
• Use gauge or other load measuring instrument to verify load.
• Never attempt to disconnect hydraulic connections under
pressure. Release all line pressure before disconnecting
hoses.
• Do not subject the pump and its components to shock
loads.
• Use only approved accessories and approved hydraulic fluid.
• Never attach ANY component not authorized by manufacturer.
• Always ensure that the chosen application is stable to work
on and around.
• Do not connect to application which can return more oil to
the reservoir than the pump reservoir can hold.
• Do not connect pump to hydraulic system powered by
another pump.
• This device is not suitable for use as support device! As
the system load is lifted, use blocking and cribbing to guard
against a falling load.
• All personnel must be clear before lowering load or
depressurizing the system.
• Never try to disassemble a hydraulic cylinder, refer repairs
to qualified, authorized personnel.
HYDRAULIC HOSES & FLUID TRANSMISSION LINES
• Avoid short runs of straight line tubing. Straight line runs
do not provide for expansion and contraction due to
pressure and/or temperature changes.
• Reduce stress in tube lines. Long tubing runs should be
supported by brackets or clips. Before operating the pump,
tighten all hose connections with proper tools. Do not
overtighten. Connections should only be tightened securely
and leak-free. Overtightening can cause premature thread
failure or high pressure fittings to burst.
• Should a hydraulic hose ever rupture, burst or need to be
disconnected, immediately shut off the pump and release
all pressure. Never attempt to grasp a leaking pressurized
hose with your hands. The force of escaping hydraulic fluid
can inflict injury.
• Do not subject the hose to potential hazard such as fire,
sharp objects, extreme heat or cold, or heavy impact.
• Do not allow the hose to kink, twist, curl, crush, cut or bend
so tightly that the fluid flow within the hose is blocked or
reduced. Periodically inspect the hose for wear.
• Do not pull, position or move setup by the hose.
• Hose material and coupler seals must be compatible with
hydraulic fluid used. Hoses also must not come in contact
with corrosive materials such as battery acid, creosote-
impregnated objects and wet paint. Never paint a coupler
or hose.
• FAILURE TO HEED THESE WARNINGS MAY RESULT IN
PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.

SETUP
IMPORTANT: The pump’s maximum working pressure is
10,000 PSI. Make sure that all hydraulic equipment such
as cylinders, hoses, couplers and etc. used with this pump
are rated at 10,000 PSI operating pressure or more.
1. 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, connect
3/8”NPTF hydraulic connection to oil outlet port, i.e.
coupler, hydraulic hose, fitting etc. Ensure all fluid ports
and thread connections are clean before connect.
Note: 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.
2. For model P8701M: The pump comes with a 4-way
valve to use with double acting cylinder. Connect two
hoses: connect one hose from the pressure port of the
pump to the pressure port of the cylinder; connect the
other hose from the retract port of the pump to the retract
port of cylinder.
If using on single acting cylinder, the valve needs to be
changed to 3-way valve. Consult BVA Technical service
888-332-6419.
3. Install a pressure gauge in-line from the pump for better
control and safety purpose.
4. Tighten securely to prevent accidental removal of
components while in use.
5. Check for leaks in system and have repaired by qualified
personnel as needed. Depressurize the hydraulic system
before servicing.
OPERATION
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.
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.
1. Remove the threaded plug, then connect the pump to
suitable application.
2. Ensure the oil level is within 1/4” (6mm) of the vent screw
opening and the system fittings and connections are leak
free before operating the pump.
3. For model P8701:
A. Close release valve by turning it clockwise. Finger
tight ONLY. Using tools on release valve can
damage it and cause the pump to malfunction.
B. Pump handle until desired pressure, load or
position is reached.
C. Pressure will maintain until the release valve is
opened.
D. To retract application, turn the release valve knob
slowly counter-clockwise (never more than 2 full
turns).
4. For model P8701M:
Use the control valve knob to control the direction
of hydraulic oil flow, refer to Figure 4(a) on page 5.
Pump handle until desired pressure, load or position is
reached.
! WARNING: Operate double-acting cylinder only
when both hoses are connected to the pump. If one
coupler is left unconnected, high pressure will build
behind the coupler which could cause personal injury
and/or equipment damage.
Note: To use with 3-way setting shown in Figure 4(b) for
application such as single acting cylinder, please have
an authorized service center to change the valve to 3-
way valve. Consult BVA Hydraulics Technical Service
888-332-6419.
5. Under no load or 1st stage condition, the pump operates in
high flow for rapid advance. When load is contacted, the
pump will automatically shifts to the 2nd stage for building
pressure. When pump pressure reaches approximately
290 psi, you must momentarily stop pumping and raise
the handle to shift to the high pressure stage. After the
pump shifts, pumping takes less effort.
Note: Operate pump handle at slower speed during the
high flow 1st stage to ensure the pump deliver maximum
oil volume.

MAINTENANCE
1. Inspect hoses and connections daily. Replace damaged
components immediately with BVA Hydraulics
Replacement Parts only.
2. Tighten connections as needed. Use pipe thread sealing
compound when servicing connections.
3. Use only good quality hydraulic fluid. We recommend
Mobil DTE 13M or equivalent. Never use brake fluid,
transmission fluid, turbine oil, motor oil, alcohol,
glycerin etc. Use of other than good quality hydraulic
oil will void warranty and damage the pump, hose, and
application.
Adding Hydraulic Fluid
1. Depressurize and disconnect hydraulic hose from
application.
2. With pump in its upright, horizontal position, remove vent
screw located on top of the reservoir.
3. Use a small funnel to fill reservoir to within 1/4” (6mm)
of the opening.
4. Wipe up any spilled fluid and reinstall the vent screw.
Changing Hydraulic Fluid
For best results, change fluid once a year.
1. Remove drain plug, then drain used fluid into a sealable
container.
2. Dispose of fluid in accordance with local regulations.
3. Reinstall drain plug.
4. Remove vent screw and fill reservoir with a good quality
hydraulic oil until ~1/4” (6mm) from the opening.
5. Reinstall vent screw.
Lubrication
Use a light machine oil to lubricate pivot points, hinges
etc.
Storage
1. When not in use, depressurize and disconnect hoses
from application.
2. Close vent screw by turning it clockwise hand tight.
3. Wipe clean thoroughly.
4. Pump should be stored where protected from the
elements, abrasive dust, and damage. Store in clean,
dry environment. Avoid temperature extremes.
5. Pumps must be stored upright and horizontal ONLY.
6. Shield pump with a protective cover.
