1.0 INTRODUCTION
Overview
The Enerpac RSL torque wrench is designed for
controlled tightening and loosening of fasteners in
industrial bolting applications. The RSL torque wrench
features a low prole cassette, compact drive unit
and integrated reaction arm, making it ideal for use in
locations where workspace is limited.
Interchangeable RSL hexagon and square drive
cassettes are available in a large assortment of both
metric and imperial sizes to suit specic customer
requirements.
The RSL torque wrench can be used with a wide range
of Enerpac bolting pumps. Electric and air pumps are
available (sold separately).

2.1 Safety Precautions - RSL Torque Wrenches
Failure to observe and comply with the following
precautions could result in death or serious personal
injury. Property damage could also occur.
• Always wear protective head-wear, 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.
• Be sure your workplace is safe. Follow the
instructions in your workplace’s standard
operating procedures and be sure to observe all
communicated safety precautions.
• Do not place any part of the body between the
wrench reaction arm and the reaction point.
• Do not place any objects between the wrench
reaction arm and the reaction point. K e e p
the hoses away from the reaction points.
• 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.
• Be aware that a nut or bolt that breaks o during
operation of the tool may become a high velocity
projectile.
• Be sure appropriate guards are securely in position
and free from damage.
• Keep your hands away from the fastener being
loosened or tightened. Tightening and loosening
nuts and bolts involves little visible movement.
However, the pressures and loads are extreme.
• Stop operation immediately if a gap appears
between the torque wrench drive and hex cassette
or square drive cassette. Have the tool inspected
and repaired before it is operated again.
• Maximum allowable pressure for the RSL torque
wrench is 10,000 psi [690 bar]. Do not exceed this
pressure setting.
• Always be sure that pump is stopped and all
pressure is fully relieved (0 psi/ bar) before
disconnecting or connecting hydraulic hoses. The
sudden and uncontrolled release of pressurized oil
could occur if hoses are disconnected while under
pressure.
• Never attempt to connect or disconnect hoses
while the pump is on and/or the system is
pressurized.
WARNING
• Be certain that all hose couplings are fully
connected at both the pump and wrench ends
before applying any hydraulic pressure. If the
couplings are not fully connected, oil ow will be
blocked, and the drive unit could be subjected to
excessive hydraulic pressures. Catastrophic failure
of wrench could result.
• Never attempt to force the drive unit onto the
cassette if it becomes dicult to install. Have the
drive unit and cassette inspected and repaired
before placing the wrench back into service.
• Never apply more hydraulic pressure to any tool,
hose, tting or accessory than the maximum
allowable pressure as stated in the manufacturer’s
specications. The system operating pressure
must not exceed the pressure rating of the lowest
rated component in the system.
• Be sure the operator has completed safety induction
training, specic to the work surroundings. The
operator should be thoroughly familiar with the
controls and the proper use of the tool.
• The operator must be of at least the minimum age
required by applicable local regulations, laws and
the facility standard operating procedures.
• Do not abuse or overstress the hoses in any way.
Do not bend the hoses excessively.
• Take every precaution to prevent oil leaks from
occurring. High pressure oil leaks can penetrate
the skin, resulting in serious injury.
• Never strike the tool while it is pressurized or under
load. Components under tension may become
dislodged, allowing them to become dangerous
projectiles. Uncontrolled release of pressurized
hydraulic oil could also occur.
• Avoid striking the tool at any time, even when it
is not pressurized or under load. Striking the
tool could cause permanent damage to wrench
components and may aect the wrench calibration.
• Use only a high quality non-ammable solvent
for cleaning and degreasing parts during wrench
repair procedures. To reduce the risk of re or
explosion, do not use ammable solvents.
• Be sure to wear proper eye and hand protection
when using solvent. Always follow the solvent
manufacturer’s safety and use instructions and
any additional instructions included in the standard
operating procedures for your work-site. Be certain
there is adequate ventilation when using solvent.

Failure to observe and comply with the following
precautions could result in minor or moderate personal
injury. Property damage could also occur.
• Always carry the wrench by its housing. The
positioning handle is designed only as an aid to
help position the wrench on the bolt or nut.
• Be sure that the backup wrench (on the opposite
end of nut or bolt being tightened or loosened) is
secured so it cannot drop or become disengaged
during bolting procedures.
• Be sure that the hex ratchet size corresponds
to the size of the fastener being loosened or
tightened. Failure to observe this precaution can
result in the wrench becoming unstable and can
lead to catastrophic failure of the tool.
• Always position the wrench for maximum stability.
A positioning handle is available to properly
position tool during operation.
• Be sure reaction points are adequate for the forces
at work during operation of the tool.
• Be sure the reaction point is of a suitable shape. If
possible, use an adjacent nut or bolt as a reaction
point.
• When the hex ratchet is placed on the nut or bolt
a gap may exist between the reaction arm and
the reaction point. When the tool is operated the
reaction arm and point will make forceful contact.
Be sure the wrench is stable before applying
hydraulic pressure.
• Provide adequate support in vertical and inverted
applications.
• The torque required to loosen a nut is variable and
may exceed the torque capacity of the wrench.
Never operate the wrench at or above 75 percent
of its rated maximum torque when loosening a nut
or bolt.
• Be sure to minimize torsional and bending stresses
in the wrench, the hex ratchet and any accessories.
• Bolt lubricants and anti-seize compounds will have
a rated coecient of friction. Be sure to know the
coecient of friction for the lubricant or anti-seize
compound that is being used. To ensure proper
tightening of nuts and bolts, always use this
coecient of friction when calculating required
torque values.
• Take care to avoid all pinch points.
CAUTION
Failure to observe and comply with the following
precautions could result in property damage and/or
void the product warranty.
• Never carry the wrench by its hoses.
• Always use Enerpac pumps and hoses.
• Always use Enerpac replacement parts.
• The maximum torque output of the wrench must
always exceed the torque required to loosen or
tighten the nut or bolt.
• Never operate the wrench with a hydraulic supply
connection to the advance side only as this may
damage the internal parts.
• In severe service conditions, be aware that the
wrench must be inspected, cleaned and lubricated
more frequently than normal.
• If oil leakage is present from drive unit, replace
seals as required before placing the drive unit back
into service.
• If the wrench is dropped from a signicant height,
have the tool inspected and checked for proper
operation before placing it back into service.
• Always follow the inspection and maintenance
instructions contained in this manual. Perform
maintenance and inspection activities at the
specied time intervals.
• Remove handle and brackets when needed.
