SAFETY AND GENERAL INFORMATION
Save these instructions. For your safety, read and understand
the information contained within. The owner and operator shall
have an understanding of this product and safe operating
procedures before attempting to use this product. Instructions
and safety information shall be conveyed in the operator's
native language before use of this product is authorized. Make
certain that the operator thoroughly understands the inherent
dangers associated with the use and misuse of the product. If
any doubt exists as to the safe and proper use of this product
as outlined in this factory authorized manual, remove from
service immediately.
Inspect before each use. It is recommended that, prior to each
use, an inspection be done by qualied personnel and that any
missing or damaged parts, decals, warning/ safety labels or
signs be replaced with BVA Hydraulics authorized replacement
parts only. Any pump that appears to be damaged in any way,
is worn, leaking or operates abnormally shall be removed from
service immediately until such time as repairs can be made.
Any pump that has been or suspected to have been subject
to a shock load (a load dropped suddenly, causing the system
pressure to exceed 10,000 PSI), shall be removed from service
immediately until checked out by a BVA Hydraulics authorized
service center. Owners and operators of this equipment shall
be aware that the use and subsequent repair of this equipment
may require special training and knowledge.
PRODUCT DESCRIPTION
BVA Hyd raulics Double Acting Air Hydrau lic Pump is
engineered to meet most industrial standards for Performance
and Safety. It is an air hydraulic pump with 4-way valve. It’s
unique hydraulic circuit allows quick displacement of hydraulic
uid under no load conditions and easy pumping in loaded
conditions. Pump supplies compressed hydraulic uid to
compatible double-acting cylinder, anywhere that 10,000 PSI
of uid pressure is needed. It is suited for plant maintenance,
production, bolting, vehicle repair, and any task that requires
hydraulic pressure from air input. Special skill, knowledge
and training may be required for a specic 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 and others
in the work area.
WARNING:
!
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.
WARNING: 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
• Stu dy, und ers tan d, and fo llo w al l
instructions provided with and on this
device before use.
• No alter ation shall be made to this
device.
• Alw ay s wea r pr ot ective gear wh en
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 means. Never rely on
hydraulic pressure alon e to suppor t
load.
HYDRAULIC PUMPS
• The user must be a qualied 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 damaged, altered or in poor condition. Do not
operate 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
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.
• Clear all personnel before lowering load or depressurizing
the system.
• Do not disassemble hydraulic cylinder, refer repairs to
qualied, 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 off the pump and release
all pressure. Never attempt to grasp a leaking pressurized
hose with your hands. The force of escaping hydraulic
uid can inict 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, creosoteimpregnated 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.

BEFORE USE
1.
Before using this product, read the instruction manual
completely and familiarize yourself thoroughly with the
product and the hazards associated with its improper use.
2. Know your pump, its limitations and how it operates before
attempting to use.
3. Replace shipping plug (red color) with air vent plug (black
color) before use. Refer to item #68 on Service Parts
Sheet.
4. Remove plastic cap from the air inlet port on the end of the
pump, then connect with a 1/4”NPT air nipple (not supply
with pump). Use teon tape or similar thread sealant on
thread connection.
NOTICE: When using the teon tape or pipe thread compound.
Tighten securely to prevent accidental removal of compound
while in use. Take care not to introduce compound into port
orices.
WARNING: Always monitor pressure, load or position
!
using suitable equipment. Pressure may be monitored
by means of an optional manifold and gauge. 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. Connect air supply to the 1/4” NPT air nipple.
2. Remove manifold plug, connect to hydraulic hoses and
suitable application.
3. Shift the valve to desired position. There are three positions
available, refer to Figure 2 on below for the owpath.
4. After shifting the valve, press on the foot pedal until desired
pressure, load or position is reached. Always monitor
pressure, load or position using suitable equipment.
Pressure may be monitored by means of optional
manifolds and gauges (contact BVA Hydraulics). Load
may be monitored by means of a load cells and digital
indicators.
OPERATION
WARNING: To reduce the risk of personal injury and/
!
or
property damage, hydraulic connections must be
securely fastened before building pressure in the
system. Release all system pressure before loosening
any hydraulic connection in the system.
