2 Safety

Be aware that the operator is fully
responsible during the operation of this
tool. Enerpac is not responsible for
damage or injury caused by misuse of this
tool. Under some circumstances additional
safety requirements may be required.
Contact Enerpac immediately if a
potentially hazardous situation arises.

Read this manual carefully and observe all
safety precautions.

- Make sure you have completed a
safety induction training, specific to
the work surroundings. The operator
should be thoroughly familiar with the
controls and the proper use of the
tool.

- The operator must be at least 18
years of age.

- Always wear protective headwear, ear
protectors, footwear and gloves (at a
minimum rigger type gloves) suitable
for safe operation of the tool. The
protective clothing must not interfere
with safe operation of the tool or
restrict the ability to communicate
with co-workers.

- Make sure your workplace is safe.

- Do not place any part of the body
between the reaction arm and the
reaction point.

- Do not place any objects between the
reaction arm and the reaction point.
Keep the hoses away from the
reaction points.

1 Introduction

Enerpac S-Series

The Enerpac S-series of lightweight
hydraulic wrenches have been designed to
tighten and loosen nuts and bolts for
professional applications. The tool has an
interchangeable drive shaft for which a
wide range of socket sizes are available.
The adjustable reaction arm further
enhances the flexibility of the tool.
The tool easily connects to the range of
available Enerpac pumps. Enerpac can
supply air, electric or hand operated
pumps.

Delivery instructions

Upon delivery all components must be
inspected for damage incurred during
shipping. If damage is found the carrier
should be notified at once. Shipping
damage is not covered by the Enerpac
warranty.

against defects in workmanship and
materials for as long as you own
them.

Any misuse or alteration invalidates the
warranty.

• Observe all instructions as laid down
in this manual.

• Replace any parts with Enerpac spare
parts only.

- Do not stand in the line of movement
of the tool when it is in operation. If
the tool separates from the nut or bolt
during operation it will detach in that
direction.

- Tightening and loosening nuts and
bolts involves little visible movement.
The pressure and loads, however are
extreme. Keep your hands away from
the fastener being loosened or
tightened.

- Make sure that the spanner used to
keep the nut or bolt on the opposite
end is secured.

- Always use Enerpac pumps and
hoses.

- Make sure appropriate guards are
always securely in position and free
from damage.

- Maximum pressure is 690 bar (10,000
psi). Never apply more pressure to
any tool or accessory than the
maximum allowable pressure. Refer to
the technical data tables for maximum
pressure setting.

- Make sure that the socket size
corresponds to the size of the
fastener being loosened or tightened.
Always make sure that the socket
receptacle corresponds to the drive
shaft. Failure to do so can result in the
tool becoming unstable and can lead
to catastrophic failure.

- Do not abuse or overstress the hoses
in any way. Do not bend the hoses
excessively.

- Never carry the tool by its hoses.

- Always use Enerpac spare parts.

- Always position the tool for maximum
stability.

- Make sure reaction points are
adequate for the forces at work
during operation of the tool.

- Be aware that a nut or bolt that
breaks off during operation of the tool
will become a high velocity projectile.

- Make sure the reaction point is of a
suitable shape. For example use an
adjacent nut or bolt as a reaction
point.

- When the hex socket is placed on the
nut or bolt a gap may exist between
the reaction arm and the reaction
plate. When the tool is operated the
reaction arm and point will make
forceful contact. Always make sure
the tool is stable.

- Provide adequate support in vertical
and inverted applications.

- The maximum torque output of the
tool must always exceed the torque
required to loosen or tighten the nut
or bolt.

- The torque required to loosen a nut is
variable and may exceed the torque
capacity of the tool. Therefore never
operate the tool at maximum or close
to maximum capacity when loosening
a nut or bolt.

- Never operate the tool with a
hydraulic supply connection to the
advance side only as this may
damage the internal parts.

- If the wrench is dropped from a
height, have the tool inspected before
you operate it again.

- In severe conditions the tool must be
cleaned and lubricated more frequently.

- Make sure to minimize torsional and
bending stresses in the tool, the
ratchet and any accessories.

- Do not strike the tool with a hammer
while under a full load. This will
invalidate the guarantee.

- Use of extension pieces or long-reach
sockets is not recommended. They
increase torsional and bending stresses,
and reduce stability of the tool.

- Always observe the maintenance
instructions.
