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.
