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 qualified 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 fluid flow 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 fluid can ignite and burn. 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 the entire saddle surface. Do not
off-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 qualified, 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 fluid.
Heavy
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 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.
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 fittings to burst.
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.
