2.1  Introduction

Read all instructions carefully. Follow all recommended safety 

precautions to avoid personal injury as well as damage to the 

product and/or damage to other property. Enerpac cannot be 

responsible for any damage or injury from unsafe use, lack of 

maintenance or incorrect operation. Do not remove warning

arise, contact Enerpac or a local Enerpac distributor for 

clarification.
If you have never been trained on high-pressure hydraulic 

safety, consult your distributor or service center for information 

about an Enerpac Hydraulic Safety Course.
This manual follows a system of safety alert symbols, signal 

words and safety messages to warn the user of specific 

hazards. Failure to comply with these warnings could result

injury hazards. Pay close attention to Safety Alert 

Symbols and obey all safety messages that follow this symbol 

to avoid the possibility of death or serious personal injury.

Safety Alert Symbols are used in conjunction with certain 

Signal Words that call attention to safety messages or property 

damage messages and designate a degree or level of hazard 

seriousness. The Signal Words used in this manual are
