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,
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
ENERPAC parts are designed to fi t properly and
withstand high loads.

pipe thread, use sparingly and never over
ends of fi ttings where it can be torn loose
and get into the hydraulic system.
4.
Connect control station.
5.
Install pressure gauge, if required, into proper
port. Pressure can be monitored at the "GP"
ports, the "GB" port or the "GA" port or any
combination of these, depending on system
requirements.
6.
Connect motor to specifi ed electrical outlet.
7.
Start pump motor. The valve is now automatically
in the NEUTRAL/HOLD position.

1.
Install a gauge on the pump. If a unit is equipped
with optional pressure transducer, verify "SET
PRES" value is higher than desired relief valve
setting or Auto Mode is off.
2.
Start the pump to allow the oil to warm.
