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
safety, consult your distributor or service center for a free
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

2.2 General Hydraulic Safety Precautions
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Do not remove or disable the pump relief valve.
• Never set a relief valve to a higher pressure than the
maximum rated pressure of the pump.
• The BLS Series Climbing Jacks are designed for a maximum
pressure of 690 Bar [10,000 psi]. Do not connect a pump
with a higher pressure rating to these jacks.
• Wear personal protective gear when operating hydraulic
equipment. Always wear eye protection. Safety equipment
such as dust mask, non-skid safety shoes, hard hat, or
hearing protection used for appropriate conditions will
reduce personal injuries.
• Stay clear of loads supported by hydraulics. To avoid
personal injury, keep hands and feet away from jack and
work piece during operation.
