BVA Hydraulics HD20006 Manual De Instrucciones página 3

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.
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.
Both couplers on the cylinder must be connected
to the pump. Double-acting cylinder must be used
with a pump equipped with 4-way valve.
Do not adjust or remove the safety relief valve.
Higher setting than rated pressure will result in
equipment damage and/or personal injury.
• 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.
INSTALLATION
NOTICE: Use an approved, high-grade pipe sealant to seal all
hydraulic connections.
1. Remove the dust cap 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.
!
Wear protective gear when operating
hydraulic equipment.
WARNING
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.
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.
Each double acting cylinder is equipped with a
pressure relief valve in the return circuit which will
open as internal pressure exceeds10K psi.
When this occurs, oil will be directed outside of the cylinder
walls and onto the cylinder body. This will create a slippery,
hazardous condition in the immediate work area. Clean up
oil immediately!
!
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 subject hose to sharp objects or heavy
impact.
