1.0 IMPORTANT RECEIVING INSTRUCTIONS
Visually inspect all components for shipping damage. Shipping
damage is
not
covered by warranty. If shipping damage is found,
notify carrier at once. The carrier is responsible for all repair and
replacement costs resulting from damage in shipment.
SAFETY FIRST
2.0 SAFETY ISSUES
Read all instructions, warnings and cautions
carefully. Follow all safety precautions to avoid
personal injury or property damage during system
operation. Norco cannot be responsible for damage or injury
resulting from unsafe product use, lack of maintenance or incorrect
product and/or system operation. Contact Norco when in doubt as
to the safety precautions and operations. If you have never been
trained on high-pressure hydraulic safety, consult your distribution
or service center for a safety course.
Failure to comply with the following cautions and warnings could
cause equipment damage and personal injury.
A
CAUTION
is used to indicate correct operating or maintenance
procedures and practices to prevent damage to, or destruction of
equipment or other property.
A
WARNING
indicates a potential danger that requires correct
procedures or practices to avoid personal injury.
A
DANGER
is only used when your action or lack of action may
cause serious injury or even death.
WARNING:
Wear proper personal protective gear when
operating hydraulic equipment.
WARNING: Stay clear of loads supported by hydraulics.
A cylinder, when used as a load lifting device, should never
be used as a load holding device. After the load has been
raised or lowered, it must always be blocked mechanically.
WARNING: USE ONLY RIGID PIECES TO HOLD LOADS.
Carefully select steel or wood blocks that are capable of
supporting the load. Never use a hydraulic cylinder as a
shim or spacer in any lifting or pressing application.
DANGER:
To avoid personal injury keep hands and
feet away from cylinder and workpiece during
operation.
WARNING:
Do not exceed equipment ratings. Never
attempt to lift a load weighing more than the capacity of
the cylinder. Overloading causes equipment failure and
possible personal injury. The cylinders are designed for a max.
pressure of 700 bar [10,000 psi]. Do not connect a jack or cylinder
to a pump with a higher pressure rating.
Never
set the relief valve to a higher pressure than the
maximum rated pressure of the pump. Higher settings may
result in equipment damage and/or personal injury.
WARNING:
The system operating pressure must not
exceed the pressure rating of the lowest rated component
in the system. Install pressure gauges in the system to
monitor operating pressure. It is your window to what is happening
in the system.
CAUTION:
Avoid damaging hydraulic hose. Avoid sharp
bends and kinks when routing hydraulic hoses. Using a
bent or kinked hose will cause severe back-pressure.
Sharp bends and kinks will internally damage the hose leading to
premature hose failure.
Do not
drop heavy objects on hose. A sharp impact may
cause internal damage to hose wire strands. Applying
pressure to a damaged hose may cause it to rupture.
IMPORTANT:
Do not lift hydraulic equipment by the
hoses or swivel couplers. Use the carrying handle or
other means of safe transport.
CAUTION: Keep hydraulic equipment away from
flames and heat.
Excessive heat will soften packings
and seals, resulting in fluid leaks. Heat also weakens
hose materials and packings. For optimum performance do not
expose equipment to temperatures of 65°C [150°F] or higher.
Protect hoses and cylinders from weld spatter.
DANGER: Do not handle pressurized hoses.
Escaping
oil under pressure can penetrate the skin, causing serious
injury. If oil is injected under the skin, see a doctor
immediately.
WARNING:
Only use hydraulic cylinders in a coupled
system. Never use a cylinder with unconnected couplers. If
the cylinder becomes extremely overloaded, components
can fail catastrophically causing severe personal injury.
WARNING: BE SURE SETUP IS STABLE BEFORE
LIFTING LOAD.
Cylinders should be placed on a flat
surface that can support the load. Where applicable, use a
cylinder base for added stability. Do not weld or otherwise modify
the cylinder to attach a base or other support.
Avoid
situations where loads are not directly centered on
the cylinder plunger.
Off-center loads produce
considerable strain on cylinders and plungers. In addition,
the load may slip or fall, causing potentially dangerous results.
