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 fittings for signs of wear or damage,
and replace as needed. Clean all threads and fittings.
3. Connect hydraulic hose from hydraulic pump to the cylinder
coupler. Ensure that there are no fluid leaks.
4. Install in-line pressure gauge.
5. Check for leaks in system and have repaired by qualified
personnel.
NOTICE: The use of cylinder attachments or extensions
reduces the cylinder capacity by at least 50% per attachment/
extension.
WARNING: 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 fittings to burst.
WARNING: Before repairs are made, depressurize
cylinder.
Tips for 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.
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 hydraulic
equipment away from flames and heat. Excessive
heat will soften seals, resulting in fluid 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 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 qualified, 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 fluid.
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 qualified
operator familiar with 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 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 fluid flow within hose is blocked or reduced.
Periodically inspect the hose for wear.
