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. 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.
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.
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 350 bar
[5,000 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.

B651 Hydraulic Intensifier
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
catastrophically causing severe personal injury.
IMPORTANT: Hydraulic equipment must only be serviced by a
qualified hydraulic technician. For repair service, contact the
Authorized ENERPAC Service Center in your area. To protect
your warranty, use only ENERPAC oil.
WARNING: Immediately replace worn or damaged parts by
genuine ENERPAC parts. Standard grade parts will break causing
personal injury and property damage. ENERPAC parts are
designed to fit properly and withstand high loads.
3.0 DESCRIPTION
Enerpac intensifiers are designed with built-in automatic reciprocation
which provides continuous intensified pressure output to 5,000 psi (350
bar) to automatically make up for system leakage.
Enerpac intensifiers are designed for high-pressure, low-volume
applications such as: holding, clamping, cutting, crimping, and molding, or
for hydraulic power tools.
CAUTION: Maximum inlet oil flow to the intensifier is 0.4 GPM.
Using higher flow rates will damage the internal shuttle valve.
