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. Do not use if leaking, broken, bent,
cracked or otherwise damaged parts are noted. If the cylinder
has been or suspected to have been subjected to a shock load
(a load dropped suddenly, unexpectedly upon it), discontinue
use 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. It is recommended that
an annual 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 cylinder that appears to be damaged in any way,
is worn or operates abnormally shall be removed from service
immediately until such time as repairs can be made.
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 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,
SPECIFICATIONS
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.
WARNING: NEVER use hydraulic cylinder as a sup-
!
port device!
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: 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.

INSTALLATION
NOTICE: 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 qualied
personnel.
NOTICE: The use of cylinder attachments or extensions
reduces the cylinder capacity by at least 50% per attachment/
extension.
! 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 qualied
operator familiar with correct operation, maintenance, and
use of cylinders.
Wea r pr o t ect i v e g e a r w h en
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 work piece
during operation.
WARNING: Before operating the pump, tighten all
!
hose connections with proper tools. Do not overtighten.
Connections should only be tightened securely and leakfree. Overtightening can cause premature thread failure
or high pressure ttings to burst.
WARNING: 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.
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. Release system
pressure before disconnecting hydraulic hose or
connections. Do not subject hose to sharp objects
or heavy impact.
Hydraulic fluid is flammable. Keep
equipment away from ames and heat.
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.

Excessive
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 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 operating
pressure. Burst hazard exists if hose, connection
or any other component in 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 hose is blocked or reduced.
Periodically inspect the hose for wear.
Center load on cylinder. Distribute load evenly
across entire saddle surface. Do not off-center
loads on a cylinder. Load may tip or cylinder can
“kick out”.
Never disassemble hydraulic cylinder, refer repairs
to qualied, authorized personal. Contact BVA
Hydraulics tech service for authorized service
center.
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.
