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. 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 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 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.
