Read 

all 

instructions, 

warnings 

and 

cautions 

carefully.  Follow  all  safety 

precautions  to  avoid  personal  injury  or  property 
damage during system operation. Enerpac cannot be 
responsible for damage or injury resulting from unsafe 
product use, lack of maintenance or incorrect product 
and/or  system  operation.  Contact  Enerpac  when  in 
doubt as to the safety precautions and operations. If 
you  have  never  been  trained  on  high-pressure 
hydraulic  safety,  consult  your  distribution  or  service 
center for a free Enerpac Hydraulic safety course.

Failure  to  comply  with  the  following  cautions  and 
warnings  could  cause  equipment  damage  and 
personal injury.

CAUTION

 is used to indicate correct operating or 

maintenance  procedures  and  practices  to  prevent 
damage  to,  or  destruction  of  equipment  or  other 
property.

WARNING

  indicates  a  potential  danger  that 

requires  correct  procedures  or  practices  to  avoid 
personal injury.

DANGER 

is only used when your action or lack of 

action may cause serious injury or even death.

WARNING:

 

Wear 

proper 

personal 

protective  gear  when  operating  hydraulic 
equipment.

WARNING: 

Stay clear of loads supported 

by hydraulics. A cylinder, when used as a 
load  lifting  device,  should  never  be  used 
as  a  load  holding  device.  After  the  load 

has  been  raised  or  lowered,  it  must  always  be 
blocked mechanically.

WARNING:  USE  ONLY  RIGID  PIECES 
TO  HOLD  LOADS

.  Carefully  select  steel 

or  wood  blocks  that  are  capable  of 

supporting  the  load.  Never  use  a  hydraulic  cylinder 
as  a  shim  or  spacer  in  any  lifting  or  pressing 
application.

DANGER: 

To  avoid  personal  injury 

keep hands and feet away from cylinder 
and workpiece during operation.

WARNING: 

Do  not  exceed  equipment 

ratings.  Never  attempt  to  lift  a  load 
weighing  more  than  the  capacity  of  the 
cylinder.  Overloading  causes  equipment 

failure and possible personal injury. The cylinders are 
designed for a max. pressure of 700 bar [10,000 psi]. 
Do not connect a jack or cylinder to a pump with a 
higher pressure rating.

WARNING:  Never  set  the  relief  valve 
pressure  above  10,500  psi  [725  bar]. 

Serious personal injury could result if this 

maximum  limit  is  exceeded.  Damage  to  pump  and 
components may also occur.

WARNING: 

The 

system 

operating 

pressure  must  not  exceed  the  pressure 
rating  of  the  lowest  rated  component  in 
the system. Install pressure gauges in the 

system  to  monitor  operating  pressure.  It  is  your 
window to what is happening in the system.
