2.0 SAFETY ISSUES
Read all instructions carefully. Follow all recommended safety
precautions to avoid personal injury as well as damage to the jack
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 DANGER, WARNING,
CAUTION and IMPORTANT.
DANGER: Indicates a hazardous situation that, if not

PR Series Electric Operated Models
The High Voltage Symbol indicates that high voltage
is present inside an enclosure or device, and that a risk
of electric shock exists. To prevent death or serious
personal injury resulting from an electric shock, always disconnect
power cord from electrical outlet or other power source before
performing any inspection, maintenance or repair procedures.
1.2 Safety Precautions - Pow'r Riser Lifting Jacks
WARNING: Failure to observe and comply with the
following precautions could result in death or serious
personal injury. Property damage could also occur.
• Keep hands and feet away from hydraulic cylinder and related
components during jack operation.
• Always wear proper personal protective equipment (PPE)
when operating hydraulic equipment (such as gloves, eye
protection, head protection, protective footware, etc.).
• Do not handle pressurized lines. Escaping oil under pressure
can penetrate the skin, causing serious personal injury. If oil is
injected under the skin, see a doctor immediately.
• The jack is to be used only for lifting loads only. Never use the
jack for pushing or separating objects, or for other non-lifting
related purposes.
• The jack should not be used to hydraulically support the
load for any period of time after the lift has been completed.
Support the load with Enerpac U-Rings (optional accessory)
or appropriately rated load supports immediately after it has
been lifted to the desired height.
• Never exceed the rated capacity of the jack. Allow for a margin
of safety that accounts for possible shifting loads or side
loading conditions. Failure to follow this warning could cause
the jack to fail.
• Never tamper with overload protection devices. The jack's
internal relief valve must not be repaired or adjusted except by
an authorized service center. The maximum hydraulic pressure
of the jack hydraulic system must never exceed the maximum
allowed for your jack model (refer to Table 1). Higher settings
may result in personal injury and/or equipment damage.
• Be sure lifting arrangement is stable before lifting load. Use
jack only on a solid and level surface, capable of supporting
the load and the base of the jack. Always center the load on
the load cap of the jack. If the jack is not perpendicular to the
load, slipping or loss of load is possible.
