• 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
ames and heat. Hydraulic uid 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.
HYDRAULIC PUMPS
• The user must be a qualied 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.
• Do not subject the pump and its components to shock loads.
• 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.
•
Use only approved accessories and approved hydraulic uid.
• 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
qualied, 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 ttings to burst.
• Should a hydraulic hose ever rupture, burst or need to be
disconnected, immediately shut o󰀨 the pump and release all
pressure. Never attempt to grasp a leaking pressurized hose with
your hands. The force of escaping hydraulic uid can inict injury.
• Do not subject the hose to potential hazard such as re, 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 uid ow 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 uid 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.

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 conrming load is accurate and working
properly. Have gauge or load cell accuracy veried by qualied
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
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. Prepare the pump for use:
• Pull spring loaded lock pin, pivot toward rear to unlock the
handle (Fig. 3).
• Loosen vent screw counter-clockwise (Fig. 4).
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 3/8ʺ NPTF
hydraulic connection to oil outlet port, i.e. coupler, gauge
adapter, hydraulic hose etc. Ensure all uid 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 orices. 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 ttings, 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 qualied 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 ttings and
connections are leak free before operating the pump.
3. Pump may be used in horizontal and vertical position as
illustrated in Figure 5.
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.
