The hydraulic pressure applied to the wrench
is converted into torque by means of a
hydraulic cylinder and a drive lever.
See . The SQD torque wrench consists of
a wrench body (1), 360° swivel hose
connection (2), reaction arm locking
mechanism (3), square drive (4), drive release
(5) and reaction arm (6) for square drive.
Optional are the Allen-key drive (7) and
reaction arm (8) for Allen-key drives. This
reaction arm (8) must be used when inserting
the Allen-key drive (7) to tighten or loosen
socket head cap screws.
Advance and retract oil flow on the pump
must be controlled by electric valves with
cables or pneumatic valves with air hoses,
so that at any time control is possible of the
Enerpac wrench.
The advance pressure (A or P) from the
pump to the wrench must be limited to a
maximum 800 bar [11,600 psi]. The pressure
relief valve at the retract side (B or T) of the
pump must be set to a maximum 120 bar
[1740 psi]. See tables , , and on
the pages 12-17 for detailed information.
3.0 SAFETY ISSUES
Failure to comply with the
following cautions and warnings
could cause equipment damage
and personal injury.
IMPORTANT: Minimum age of
the operator must be 18 years.
The operator must have read
and understood all instructions,
safety issues, cautions and warnings before
starting to operate the Enerpac torque
wrench. The operator is responsible for his
activity towards other persons.
WARNING: To avoid personal
injury and possible equipment
damage, make sure all hydraulic
components withstand the
maximum pressure of 800 bar [11,600 psi].
IMPORTANT: Minimize the risk
of overloading. Use hydraulic
gauges in each hydraulic system
to indicate safe operating loads.
It is your window to what is happening in the
system.
WARNING: Do not overload
equipment. Overloading causes
equipment failure and possible
personal injury.
CAUTION: Make sure that all
system components are
protected from external sources
of damage, such as excessive
heat, flame, moving machine parts, sharp
edges and corrosive chemicals.
CAUTION: Avoid sharp bends
and kinks that will cause severe
back-up pressure in hoses.
Bends and kinks lead to
premature hose failure.
WARNING: Immediately replace
worn or damaged parts with
genuine Enerpac parts. Enerpac
parts are designed to fit properly
and withstand rated loads.
WARNING: Always wear safety
glasses. The operator must take
precaution against injury due to
failure of the tool or workpiece.
DANGER: Do not handle
pressurized hoses. Escaping oil
under pressure can penetrate
the skin, causing serious injury. If oil is
injected under the skin, see a doctor
immediately.
WARNING: Never pressurize
uncoupled couplers. Only use
hydraulic equipment in a
coupled system.

ted hoses cause malfunctions
and are hazardous. See on
page 7. Do not change coupler
positions on wrench equipment.
Clean coupler halves before connecting. Use
dustcaps after disconnecting. To prevent
seal damage, do not swivel couplers while
system is under full pressure.
IMPORTANT: Enerpac THC-700
series 3,5:1 safety twin hoses
must be used with double-acting
torque wrenches.
IMPORTANT: Do not lift
hydraulic equipment by the
hoses or swivel couplers. Use
the carrying handle or other
means of safe transport.
CAUTION: Do not use worn or damaged
sockets or Allen-Key drives. They must fit
precisely on the nut or bolt being torqued.

WARNING: Do not exceed
maximum torque of Allen-key
drives to avoid danger of Allen-
key drive failure and bolt-
shearing. Maximum torque of Allen-key
drives are specified in tables and .
WARNING: Exceeding the
maximum torque for a bolt size
or Allen-key drive will result in
bolt shearing and potential parts
failure. These failures could result in bolt or
insert pieces being projected from the
wrench or bolting site. Failures will also result
in the torque wrench unit moving rapidly
away from the torquing point causing
potential injury to the operator.
CAUTION: The torque wrench must be
properly positioned manually to make sure
the reaction force is safely transmitted via
the reaction arm and not via other torque
wrench parts. Do not use the torque wrench
without the reaction arm.
WARNING: The locking mechanism (3)
must be used to secure the reaction arm on
the wrench body to prevent from slipping off.
It must “click” in the slot of the reaction arm.
CAUTION: Avoid tilting the wrench. Do
not use extensions. If this is unavoidable due
to the reaction point, the torque (pressure)
must be reduced. An extra support must be
used to minimize tilting and friction. When in
doubt, contact Enerpac.

5.0 CONNECTING THE WRENCH TO
THE PUMP
Enerpac torque wrenches can be powered
by a range of electric or air-driven torque
wrench pumps. For complete operating
instructions, refer to the instruction sheet
included with each Enerpac pump.
IMPORTANT: It is mandatory
that the operator has a full
understanding of all instructions,
safety regulations, cautions and warnings,
before starting to operate any of this high
force tool equipment. To ensure correct
pump and wrench control it is recommended
to use an Enerpac torque wrench pump.
When in doubt, contact Enerpac.
IMPORTANT: Minimum age of the operator
must be 18 years. The operator is
responsible for his activity towards other
persons.
ATTENTION: In case of a interrupted current
or a failure of the pump, switch off the motor
and disconnect the torque wrench from the
pump.
DANGER: Do not use electric-
powered pumps in hazardous
environments where explosion-
proof equipment is required.
Enerpac air driven torque wrench pumps can
be used in this case.
5.1 Follow the procedure below:
1. During initial operation or start-up.
2. When changing a wrench on same pump.
3. When different torque values are needed,
using the same pump. For instance using
different Allen-key drives on the same
wrench (tables and pages 12-13).
5.2 Pump requirements
The advance pressure (P or A) from pump to
wrench must be limited to a maximum 800
bar [11,600 psi]. The pressure relief valve at
the retract side (B or T) of the pump must be
set to a maximum 120 bar [1740 psi].
IMPORTANT: Maximum oil flow to the
torque wrench: 12 l/min @ 140 bar
[732 in3/min @ 2030 psi] and
2 l/min @ 800 bar [122 in3/min @ 11600 psi].
CAUTION: See . Make sure all couplers
and hoses are fully connected and oil can
flow freely from (P to P) and (T to T).
Incorrectly mounted couplers can still be
closed, with the result that oil on the
wrenchs’ retract side (T or R) can be
pressurized by the advance side (P or V). The
safety valve in the retract side (T or R) of the
wrench (2) will open and vent oil to prevent
over-pressurization. This valve is factory set
at 225 - 300 bar [3260 - 4350 psi].
5.3 Bleeding air from the system
During first-time operation, the hydraulic
system is filled with air. Remove air by
connecting the THC-700 series hoses to
each other and cycling the pump using the
remote control. If the torque wrench is
connected, air can also be removed by
cycling the wrench several times.

5.4 Pressure and torque setting
Read the pump instructions. Without placing
the wrench on the bolt or nut, operate the
pump in the advance direction.
IMPORTANT: Before using the
pump with the torque wrench on a
bolt or nut make a functional test at
maximal 100 bar [1450 psi].
Set the required torque by adjusting the
pressure relief valve on the advance side (P)
of the pump and reading the value on the
pressure gauge.
When making bolted connections always
consult the manufacturers instructions or the
engineering recommendations.
Pressure setting can be adjusted between
40 - 800 bar [580 - 11600 psi]. Adjust the
pressure relief valve setting by turning the
spindle on the pump:
•
clockwise = higher pressure (torque)
• counter-clockwise = lower pressure (torque)
Set the torque by consulting the tables
and on pages 14-16 in this instruction
sheet, or torque versus pressure chart
included with each wrench. When using
Allen-key drives consult tables and
on pages 12-13 for max. allowed torque.
5.5 Loosening and tightening
WARNING: Switch off the pump
before changing sockets, Allen-
key drives or wrench position.
Before positioning the wrench on bolt or nut,
assemble according paragraph 4.0.
See and for correct wrench, reaction
arm and socket (or Allen-key drive) position.
Make sure pump is not running and hoses
are disconnected from the wrench. Place the
torque wrench on the bolt connection so that
the bolt head or nut is fully enclosed by the
socket or the Allen-key drive fully engaged in
the socket head cap screw.

5.6 Determining the reaction point
WARNING: To avoid personal injury keep
hands away from reaction arm and working
area during operation. See .
WARNING: Never react off loose
pieces. The force of the wrench
could cause loose pieces to
become flying objects.
IMPORTANT: The reaction arm always
moves in the direction opposite the rotation
of the socket or Allen-key drive.
CAUTION: See safety issues , , .
The wrench must react against a stationary
object.
IMPORTANT: Follow the safety issues ,
, , , , and .
CAUTION: and . The reaction force
must be fully absorbed by the reaction arm
at the same level as the socket or Allen-key
drive.
CAUTION: Do not obstruct the reaction
arm movement against reaction point. Keep
hands, hoses and swivel connection away of
reaction arm area.
5.7 Loosening and tightening (continued)
To tighten, operate the pump in the advance
direction by pressing the advance button –
refer to pump instructions. The wrench
performs it angular rotation until it reaches
the end of its rotation cycle. When the
wrench stops, release the advance button to
allow the wrench to automatically retract.
You will know when it have fully retracted as
you will not hear a ratcheting (clicking)
sound. Repeat this operation until the socket
or Allen drive no longer rotates.
ATTENTION: Socket or Allen-key drive
should not be rotating during retract cycle.
IMPORTANT: After reaching the preset
pressure (torque), the torque wrench will no
longer rotate while the gauge will read the
preset pressure value. Monitor the pressure
gauge on the pump to verify that the bolt/nut
connection has been tightened to the preset
torque values.
If a bolt or nut does not loosen, the torque
(pressure) may be increased. Do not exceed:
•maximum torque for the bolt size to
avoid danger of bolt-shearing;
•maximum pressure (torque) for the Allen-
key drive (hexagon insert) to avoid
danger of bolt-shearing and Allen-key
drive failure. Maximum torque of Allen-
key drives are specified on pages 12-13.
•maximum pressure 800 bar [11,600 psi];
WARNING: Exceeding the
maximum torque for a bolt size or
Allen-key drive will result in bolt-
shearing and potential parts
failure. These failures could result in bolt or
Allen-key drive pieces being projected from
the wrench or bolting side. Failure will also
result in the torque wrench unit moving
rapidly away from the torquing point causing
potential injury to the operator.
IMPORTANT: Misusage resulting
in broken or damaged Allen-key
drive, damage inside the torque
wrench and injury due to
misusage is not covered under Enerpac
warranty. Maximum torque of Allen-key
drives are specified in tables and on
pages 12-13.
We recommend the use of special
loosening liquids or sprays.
Enerpac offers nutsplitters in case
a nut can not be removed.
