CAUTION: Keep hydraulic equipment away from
fl ames 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 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 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.
WARNING: Start the pump with the valve in the
neutral position to prevent accidental cylinder
operation. Keep hands clear of moving parts and
pressurized hoses.
WARNING: These pumps have internal factory
adjusted relief valves, which must not be repaired or
adjusted except by an Authorized Enerpac Service
Center.

4.0 INSTALLATION
Install or position the pump to ensure that air fl ow around the
motor and pump is unobstructed. Keep the motor clean to ensure
maximum cooling during operation.
4.1 Breather Cap and Oil Fill Plug (See Figure 2)
A shipping plug (A) is installed in the breather port on the top of
the reservoir. Before using the pump, replace the shipping plug
(A) with the breather cap (B) and adapter fi tting (C). Note: The oil
fi ll port is located on the opposite side of the pump. The oil fi ll
port uses an SAE #10 plug (D).
