PRODUCT DESCRIPTION
BVA Hydraulics Single Acting Cylinder is designed for rated
capacity pushing, spreading and pressing jobs. A wide variety
of applications exist for this category of product. Special skill,
knowledge and training may be required for a specic 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
ultimately must make the decision regarding suitability of the
product for any given task and therefore accept responsibility
for that decision. Immediately after lifting, loads must be
supported by appropriate mechanical means.
NEVER use hydraulic cylinder as a support device!
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.

WARNING
!
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 cylinders.
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 cylinder and workpiece during
operation.
• Do not exceed rated capacity of the cylinder
or
any equipment in the system. The cylinder is
designed for a max. pressure of 10,000 psi.
• Do not connect a cylinder to a pump with higher
pressure rating.
• Do not subject cylinder 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 cylinder 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.
Cylinder 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 cylinder is
fully engaged into/onto adapters, extension accessories.
Center load on cylinder. Distribute load evenly
across the entire saddle surface. Do not o󰀨-center
loads on a cylinder. The load can tip or the cylinder
can “kick out”.
Never try to disassemble a hydraulic cylinder,
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 cylinder.
• Use only factory authorized fasteners, accessories
and hydraulic uid.
INSTALLATION
IMPORTANT! Use an approved, high-grade pipe sealant to
seal all hydraulic connections.
1.
Remove the dust cover and rubber plug from coupler .
2. Inspect all threads and ttings for signs of wear or damage,
and replace as needed. Clean all threads and ttings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no uid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualied
personnel.
Note: The use of cylinder attachments or extensions reduces
the cylinder capacity by at least 50% per attachment/
extension.
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.
Before repairs are made, depressurize cylinder.
Tips for hydraulic hoses & uid 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 USE
1. Before using this product, read the owner's 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.
If in doubt, call BVA Hydraulics Technical Service (888)
332-6419.
3. Inspect before each use. Do not use if bent, broken, leaking
or damaged components are noted.
4.
Replace worn or damaged parts and assemblies with BVA
Hydraulics authorized replacement parts only. Lubricate
as instructed in Maintenance Section.
5. 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.
OPERATION
Operate the hydraulic pump to advance and retract the
cylinder. Do not continue pumping when cylinder is fully
extended. Internal pressure will build up and may damage
the seal of the cylinder.
To help prevent material fatigue if the cylinder is to
be used in a continuous application, the load should
not exceed 85% of the rated capacity.
Your cylinder, hose(s), couplings and pump all must
be rated for the same maximum operating pressure,
correctly connected and compatible with the hydraulic uid
used. An improperly matched system can cause the system
to fail.
All personnel must be clear before lowering load.
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. Always use clean, approved hydraulic uid and change as
recommended or sooner if the uid becomes contaminated
(never exceed 400 hours). Follow pump manufacturers
instructions for changing and adding hydraulic uid. Use
only good quality hydraulic uid. We recommend Mobil
DTE13M or equivalent when using with hand pump
or air pump; BVA Hydraulics Oil (FJZ01) or equivalent
when using with electric pump. 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 cylinder, pump, hose etc.
4.
Use an approved, high-grade pipe thread sealant to seal all
hydraulic connections. Teon tape can be used if only one
layer of tape is used and it is applied carefully (two threads
back) to prevent the tape from being introduced into hydraulic
system. A piece of tape could travel through the system
and obstruct the ow of uid and adversely a󰀨ect function.
Lubrication & Cleaning
Keep cylinder clean at all times.
1. Any exposed threads (male or female) must be cleaned
and lubricated regularly, and protected from damage.
Lubricate with light machine oil.
2. If a cylinder or ram has been exposed to rain, snow,
sand, airborne abrasive, or any corrosive environment, it
must be cleaned, lubricated, and protected immediately
after exposure. Daily clean exposed ram with clean cloth
dampened with light machine oil. Protect exposed ram
from the elements at all times.
3. Keep the hydraulic system as free of dirt as possible. When
not in use, couplers must be sealed with dust covers. All
hose connections must be free of dirt and grime. Any
equipment attached to the cylinder must be kept clean.
Storage
Cylinders should be stored vertically with ram plunger fully
retracted in a dry, protected area, not exposed to corrosive
vapor, dust or other harmful elements. When a cylinder has
not been used for a period of 4 months, it should be connected
to a pump and fully extended and then retracted a minimum
of 5 times. This cycle will lubricate the cylinder wall, reducing
the possibility of corrosion and damage thereof.
How to remove faulty coupler:
If cylinder does not retract,:
1. Secure load by other means.
2. Depressurize pump and hose.
3. Remove the cylinder from application.
4. Disconnect and replace with new coupler.
Important: Do not attempt to grasp 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
cylinder as shown in gure 2 below.
2. Operate pump to fully extend and retract the cylinder 2 or
3 times. The objective is to force the air bubbles up hill
and back to the pump reservoir.
3. Follow pump instruction manual to bleed the air from
pump reservoir. On most pumps, air can escape by
opening the oil ller plug/screw.
