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
by 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.
WARNING: Keep hands clear of moving parts and
pressurized hoses.
WARNING:
adjusted relief valves, which must not be repaired or
adjusted except by an Authorized Enerpac Service
Center.

For shipping purposes, a shipping plug (A) is installed in the
breather port on the top of the reservoir. Before using replace the
shipping plug with the breather cap (B). NOTE: The breather port
