Failure to comply with the following warnings
may result in personal injury as well as
property damage.
• Study, understand, and follow all instructions
provided with and on this device before use.
• The user must be a qualied operator familiar
with the correct operation, maintenance, and use of rams.
Wear protective gear when
operating hydraulic equipment.
This device is NOT suitable for use as support
device! As the load is lifted, use blocking and
cribbing to guard against a falling load. Stay
clear of a lifted load before it is properly supported .
Never rely on hydraulic pressure to support a load.
Crush Hazard. Keep hands and feet
away from ram and workpiece
during operation.
• Do not exceed rated capacity of the ram or
any equipment in the system. The ram is
designed for a max. pressure of 10,000 psi.
• Do not connect a ram to a pump with higher
pressure rating.
• Do not subject ram to a shock loads, a load
dropped suddenly, causing the system pressure to
exceed rated pressure.
The system operating pressure must not exceed
the pressure rating of the lowest rated component
the system. Install a pressure gauge or other load
measuring instrument to monitor the operating pressure. Burst
hazard exists if hose, connection or any other component in
the system exceed its rated pressure.
Avoid damaging hydraulic hose. Do not allow
hose to kink, twist, curl, crush, cut or bend so
tightly that uid ow within the hose is blocked or
reduced. Periodically inspect the hose for wear.
Do not pull, position or move ram setup by
the hose. Use carrying handle or other means
of safe transport.
Do not handle pressurized hoses. Never attempt
to grasp a leaking pressurized hose. Ensure to
release the system pressure before disconnecting
hydraulic hose or connections.
Hydraulic uid can ignite and burn. Keep
hydraulic equipment away from ames and
heat. Excessive heat will soften seals, resulting in
uid leaks. Heat also weakens hose materials.
Ram must be on a stable base which is able
to support the load while pushing or lifting. Use
shims, friction material or constrains to prevent
slippage of the base or load. Ensure ram is fully engaged
into/onto adapters, extension accessories.
Center load on ram. Distribute load evenly
across the entire saddle surface. Do not
off-center loads on a ram. The load can tip
or the ram can “kick out”.
Never try to disassemble a hydraulic ram,
refer repairs to qualied, authorized personal.
Contact BVA Hydraulics tech service for authorized
service center.
Do not subject hose to sharp objects or
heavy impact.
Hose material or seals must not come in
contact with corrosive materials such as
battery acid, creosote-impregnated objects
and wet paint. Never paint a coupler or hose.
• No alteration shall be made to the ram.
• Use only factory authorized fasteners,
accessories and hydraulic uid.

OPERATION
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.
Note: Any attachment that is not loaded centrally, as through
the centerline of the ram, is considered to be “offset”. When
extension tubes and/or offset attachments are used, the
rated capacity is always reduced by 50% for each tube or
offset attachment connected.
1. Locate and close release valve by turning it clockwise
until rmly closed. (Do not over tighten)
2. Operate by pumping handle. This will send uid from the
pump reservoir into the high pressure hose assembly and
into the ram assembly.
3. Continue pumping until ram reaches desired position.
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. To Release Pressure on work piece: Slowly, carefully turn
the release valve counter-clockwise until ram retracts
to desired position. Never turn release valve more than
1/2 full turn. The ram return system is spring loaded and
the release valve system is metered, allowing controlled
retraction of the ram.
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 uid. We recommend BVA
FJZ01 or equivalent. Never use brake uid, transmission
uid, 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 Oil
1. With ram fully lowered, set pump unit in its normal, level
position. Locate and remove oil ller screw.
2. Fill until oil is within 3/8" of the oil ller screw hole opening,
re-install oil ller screw.
Changing Hydraulic Oil
For best performance and increased system life, replace the
complete uid supply at least once per year.
1. With ram fully lowered, remove the oil ller screw from the
pump reservoir as above.
2. Lay the pump on its side and drain the uid into a suitable
container.
Note: Dispose of hydraulic uid in accordance with local
regulations.
3. Set pump in its level upright position.
4. Fill with good quality jack oil to within 3/8" of the oil ller
screw hole opening. Reinstall oil ller screw.
Lubrication
A coating of light lubricating oil to pivot points and hinges
will help to prevent rust and assure that pump assemblies
move freely.
Cleaning
Periodically check the pump piston and ram for signs of rust
or corrosion. Clean as needed and wipe with an oily cloth.
Note: Never use sandpaper or abrasive material on these
surfaces!
Storage
When not in use, store with the pump piston and ram fully
retracted.
How to remove faulty coupler:
If ram does not retract,:
1. Secure load by other means.
2. Depressurize pump and hose
3. Remove the ram from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp ram with pliers or
wrench without rst wrapping the jaws of such tool with
rags or similar padding.
How to bleed air from system:
1. Place pump at a higher elevation than the hose and ram
as shown in gure 3 below.
2. Operate pump to fully extend and retract the ram 2 or 3
times. The objective is to force the air bubbles up hill and
back to the pump reservoir.
3. To bleed the air from pump reservoir, simply open the oil
ller screw. Re-install after bleeding.
