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. Enerpac
cannot be responsible for damage or injury resulting from unsafe product use,
lack of maintenance or incorrect product and/or system operation. Contact
Enerpac 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 free Enerpac Hydraulic 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.
• Check all Coupler Connections: Make sure all coupler
connections are complete. Loose or incomplete coupler
connections will cause complete or partial blockage of oil flow.
• Check all Hose Connections: Make sure all hose connections are
properly mated and secured.
• Do Not use excessive closing torque on valve handle or use any handle
extension. This will cause unnecessary wear on valve stem and seat and
may damage the spring.
• Check for Safe System Setups: Make sure that your valve, connecting
hoses, etc. are protected from any external source of damage, such as:
excessive heat, flame, moving machine parts, sharp edges, falling
objects, corrosive chemicals, dripping, etc.
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.
