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.
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
with 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.
