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 10,000 psi [700 bar]. 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 fl uid
leaks. Heat also weakens hose materials and
packings. For optimum performance do not
expose equipment to temperatures of 150 °F
[65 °C] 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
fl at 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.
Distribute the load evenly across
the entire saddle surface. Always
use a saddle to protect the plunger.
IMPORTANT: Hydraulic equipment
must only be serviced by a
qualifi ed 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 with
genuine ENERPAC parts. Standard
grade parts will break causing
personal injury and property damage.
ENERPAC parts are designed to fi t properly
and withstand high loads.
