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.
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 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.

WARNING: Do not use electric pumps in an explosive
atmosphere. Adhere to all local and national electrical
codes. A qualified electrician must do installation and
modification.
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.
CAUTION: To prevent damage to pump electric motor,
check specifications. Use of incorrect power source will
damage the motor.

4.0 INSTALLATION
Install or position the pump to ensure that air flow around the
motor and pump is unobstructed. Keep the motor clean to
ensure maximum cooling during operation.
4.1 Reservoir Breather Cap (See Figure 2)
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 (B) is separate from the oil fill port (C). Oil fill port (C) uses a
SAE #10 plug.
