1.0  SAFETY

1.1  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 labels, 

tags, or decals. In the event any questions or concerns 

arise, contact Enerpac or a local Enerpac distributor for 

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

tool 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 in death or serious personal injury, as well 

as damage to the equipment or other property.

The Safety Alert Symbol appears throughout 

this manual. It is used to alert you to 

potential physical 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 DANGER, WARNING, CAUTION and
