NOTICE
DANGER
WARNING
CAUTION

IM_SWi_EX_Rev14 3
• Never leave the system unattended when under
pressure. When the system is under pressure DO
NOT STAND IN LINE with the direction of force of
the tool. This is a danger area. Always keep this
area clear of personnel when the system is under
pressure.
• Site pump on a secure, flat, level surface. Rope off
working area and place warning signs.
• Do not tamper with air pressure relief safety valve
on pump.
• Check the date of the calibration certification. If the
recalibration date has passed, the gauge must be
recalibrated.
• If air supply is interrupted, turn off air stop valve
on pump.
• Maximum allowable pressure for the SWi20/25TEEX
tool is 10,000 psi [700 bar]. Do not exceed this
pressure setting.
• Never strike the tool while it is pressurized or under
load. Components under the tool may become
dislodged, allowing them to become dangerous
projectiles. Uncontrolled release of pressurized
hydraulic oil could also occur.
• Use only a high-quality non-flammable solvent
for cleaning and degreasing parts during wrench
repair procedures. To reduce the risk of fire or
explosion, do not use flammable solvents.
• It is advised that a pressure gauge(s) is installed in
the system when using the SWi20/25TEEX tool to
monitor operating pressure, to allow the operator
to monitor what is happening in the system.
• Care should be taken when using the lanyard to
avoid entanglement with body parts.
Failure to observe and comply with the following
precautions could result in minor or moderate
personal injury. Property damage could also occur.
• Ensure components are protected from external
sources of damage, such as excessive heat, flame,
moving machine parts, sharp edges, and corrosive
chemicals.
• Take care to avoid sharp bends and kinks in
hydraulic hoses. Bends and kinks can cause
severe back-up pressure and cause hose failure.
Protect hoses from dropped objects; a sharp
impact may cause internal damage to hose wire
strands. Protect hoses from crush risks, such
as heavy objects or vehicles; crush damage can
cause hose failure.
• Do not lift hydraulic equipment by the hoses
or couplers. Use only the designated carrying
handles.
CAUTION
• Keep hydraulic equipment away from flames and
heat. Excessive heat will soften packings and
seals, resulting in fluid leaks. Heat also weakens

Spreading Wedge - Feature Explana-
tion
The SWi12/14TMEX Spreading Wedge uses mechanical
torque to advance the wedge and spread the jaws.
3.2.1 SWi12/14TMEX Tool Capabilities
Spreading Force
Maximum SWL torque of 175N·m [130ft·lb] will generate
12T [120kN] spreading force on the 1st step and 14T
[140kN] spreading force on the 4th step.
Spreading Gap (See Section 4.1)
Using only the 1st step, the tool can spread from 6.0mm
to 40.0mm [0.24" - 1.6"].
Using all 4 steps, but without the stepped blocks, the
tool can spread from 6.0mm to 87.5mm [0.24" - 3.4"].
Using both steps on the stepped blocks, the tool can
spread 48.5mm – 103.5mm [1.9" - 4.1"].
3.2.2 SWi12/14TMEX Tool Function
Mechanical Tool Operation
The SWi12/14TMEX Spreading Wedge uses mechanical
torque to advance the wedge and spread the jaws. The
torque is applied using the supplied Torque Wrench,
enabling accurate control of the force applied.
Figure 2:
Torque Wrench Usage
Holding the Torque Wrench in one hand, unlock the
knurled handle by turning the locking knob anti-
clockwise.
Select the torque setting by turning the knurled handle
until the required torque value is indicated.
For example, to set the Torque Wrench to 46N·m: turn
the knurled handle until the 0 on the fine scale aligns
with 40N·m on base scale; now turn slightly further until
the 6 on the fine scale aligns with the central line.

6IM_SWi_EX_Rev14
Figure 3:
Setting an imperial torque [in ft·lb] is done in exactly the
same way.
Figure 4:
Lock the handle by turning the locking knob clockwise.
Install the supplied socket onto the Torque Wrench and
attach to the tool.
Slowly and smoothly pull the handle, gradually applying
more force until you feel or hear the Torque Wrench click,
indicating that the selected torque has been achieved.
Do not continue to apply force after the Torque Wrench
has clicked. Special care should be taken when using
low torque settings.
Torque Wrench Care
Prior to storing the Torque Wrench, and between use,
leave the Torque Wrench with its lowest torque setting
selected.
To clean the Torque Wrench, wipe gently with a damp
cloth. Avoid using any detergent or solvent as this may
detrimentally affect the factory-fitted internal lubrication
of the mechanism.
Actuating The SWi12/14TMEX
Follow the Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi12/14TMEX tool in particular:
Actuate the tool by manually applying force to the torque
wrench in the clockwise direction (see Torque Wrench
Usage). Gradually increase the torque setting of the
Torque Wrench over several steps, for example 30N·m
[or 20ft·lb] each time. Do not exceed the maximum SWL
torque of 175N·m [130ft·lb].
When using multiple tools, ensure that the torque settings
of all wrenches correspond to keep the spreading force
balanced.
Retracting The SWi12/14TMEX
Retract the tool by manually applying force to the torque
wrench in the anti-clockwise direction. When using
multiple tools, work around all wrenches to keep the
spreading force balanced as the gap is closed.

3.4 SWi20/25TIEX Integral Hydraulic
Spreading Wedge - Feature Explanation
The SWi20/25TIEX Spreading Wedge uses an integral
hydraulic pump to drive the cylinder to advance the
wedge and spread the jaws.
3.4.1 SWi20/25TIEX Tool Capabilities
Spreading Force
With the maximum hydraulic pressure of 700 bar
[10 000 psi] applied, the tool can apply 20 T [200 kN]
spreading force on the 1st step, up to 24 T [240 kN]
spreading force on the 4th step.
Spreading Gap (See Section 4.1)
Using only the 1st step, the tool can spread from 6.0mm
to 40.0mm [0.24" - 1.6"].
Using all 4 steps, but without the stepped blocks, the
tool can spread from 6.0mm to 87.5mm [0.24" - 3.4"].
Using both steps on the stepped blocks, the tool can
spread 48.5mm – 103.5mm [1.9" - 4.1"].
3.4.2 SWi20/25TIEX Tool Function
Hydraulic Tool Operation
Prior to operation, ensure the air-vent in the integral
hand pump is not obstructed. Any obstruction in the air-
vent can cause a vacuum in the system which can limit
the cylinder’s travel.
The SWi20/25TIEX Spreading Wedge uses a hydraulic
cylinder to advance the wedge and spread the jaws. The
hydraulic pressure is applied using the integrated hand
pump, enabling accurate control of the force applied.
The integral hand pump has a control lever which allows
the user to select advance (+) or retract (-).

5. Operation
Figure 16:
Place the tool into the access gap, with the full width of
the selected step fully inserted up to the heel.
Figure 17:
5.2 Flange Spreading
Spread the flanges apart by actuating the tool. Consult
the relevant section of the manual for tool-specific
instructions on how to actuate each tool.
Once the joint has been opened to the desired distance,
or if the tool has reached its maximum travel, insert the
Safety Blocks into the flange joint.
Figure 18:
MINIMUM
ACCESS GAP
5.1 Initial Setup and Inspection
Before attaching the tool ensure at least two flange bolts
remain in place. These should be 180 degrees apart with
their nuts loosened sufficiently to enable flange work to
be carried out. Leaving these bolts in place will help to
reduce unwanted lateral flange movement during flange
spreading.
Figure 14:
Prior to spreading, an assessment should be carried
out to determine the most appropriate positioning of
the tools around the joint. A minimum of 2 tools should
always be used.
Figure 15:
Determine the flange joint access gap:
• Minimum access gap of 6 mm [0.24"] is required for
SWi12/14TMEX/ SWi20/25TIEX/ SWi20/25TEEX
tools.
The access gap is the clearance between the surfaces
onto which the wedge will apply its spreading force.

16 IM_SWi_EX_Rev14
Ensure the full width of the selected Safety Block step is
fully inserted before gradually retracting the tool until the
flange load has been applied to the Safety Block.
Figure 19:
The wedges can then be retracted fully and inserted
again, using the next step. In this way the flange joint
can be iteratively opened further until the required
spread is reached.
5.3 Flange Work
Do not rely upon hydraulic systems for
supporting the access gap during flange work. Do not
allow fingers, hands or other body parts into the space
created between the flanges.
5.4 Flange Closure
Allow the flanges to return to their closed position
by gradually retracting the tool. Consult the relevant
section of the manual for tool-specific instructions
on how to retract each tool. Before the tool has fully
retracted, insert the Safety Blocks into the flange joint.
Ensure the full breadth of the selected Safety Block step
is fully inserted, before gradually retracting the tool until
the flange load has been applied to them.
Figure 20:
To use the next smallest step, actuate the wedges to
around 75% prior to inserting back into the joint. Place
the tool in the gap and actuate enough to relieve the
load on the Safety Blocks. In this way the flange joint
can be progressively closed.
WARNING
As the flange approaches its fully closed position,
support the tool to avoid it dropping out of the joint.
Ensure that care is taken to prevent objects being
dropped. Dropped objects pose a risk of personal injury
or equipment damage.
5.5 Safety Blocks
Each tool is supplied with a set of 2 Safety Blocks.
The Safety Blocks have been designed with steps that
match the spreading distance of the SWi tools.
Figure 21:
5.6 Stepped Blocks
SWi12/14TMEX, SWi20/25TIEX, and SWi20/25TEEX
tools are supplied as standard with a pair of Stepped
Blocks These can be fixed to the jaws (individually or
in pairs) to increase the effective jaw thickness and
therefore the maximum spreading distance.
Use of the Stepped Blocks also enables the SWi tools to
be used in a joint with a larger access gap.
Wedge protrusion can be minimised by the use of
Stepped Blocks, reducing the penetration into the
joint. This enables, for example, spectacle blinds to be
changed.
Attach the stepped block to the tool using the M6
counter-sunk screw. Use the hex-key supplied to tighten
the screw into the threaded hole in the jaw of the tool.
Repeat for second Stepped Block to further increase
the effective jaw thickness if required.
Figure 22:

IM_SWi_EX_Rev14 17
To remove the Stepped Blocks unscrew the M6 counter-
sunk screw. Do not force the screw out of the Stepped
Block, it is deliberately retained to prevent it becoming
misplaced.
Use the tool as per the Tool Operation instructions.
Ensure that there is a minimum hold of 15mm [0.59"]
and that the full width of the block is used.
Figure 23:
5.7 Handle
The handle can be swivelled around the central axis
of the tool, to improve access to the Flange and allow
the tool to be easily held in the vertical or horizontal
orientation.
If the tool is being used in an application where access
space is very limited, the handle can be removed
temporarily.
Removing Handle (SWi12/14TMEX, SWi20/25TIEX,
SWi20/25TEEX)
Unclip the spiral ring and remove the anchor point and
handle. Special caution should be exercised when
working with a tool in this configuration. Replace the
handle immediately following the task.

5.8 Lanyard
SWi tools are supplied with a secure anchor point and
a lanyard. The lanyard should be used to minimise the
risks associated with the tool dropping.
Attach one end of the lanyard to the tool using the
supplied shackle. The other end of the lanyard should
be fixed to a secure point close to the work-site using an
appropriate shackle.
Avoid using the lanyard as a means for picking up or
carrying the tool. Do not fix the lanyard to the handle.
The anchor point and lanyard have been engineered to
safely sustain a drop over the full lanyard length. It is
recommended that all parts are inspected following a
drop incident, as damage may compromise the safety
of the tool.
Only use the designated anchor point/
holes for fixing the lanyard as shown in figures 11 and
12. Do not attach the lanyard to the plastic handle.
Care should be taken when using the
lanyard to avoid entanglement with body parts.

5.9 Sub-Sea Usage
5.9.1 SWi20/25TIEX
SWi20/25TIEX tools are actuated by means of single-
acting spring-return hydraulic cylinder and can be used
sub-sea providing the following actions are taken:
• The pump release valve is fully opened and remains
open until the tool has descended to the working
depth. This will allow the pressure to equalise.
• The tool is actuated via the hand pump by a diver.
• Upon completion of works the release valve is
left in the fully-open position until the tool has
ascended to the surface.
• The tool is stripped-down, cleaned and lubricated
immediately to minimise corrosion.
5.9.2 SWi12/14TMEX
The SWi12/14TMEX is actuated mechanically and can
be used sub-sea providing the following actions are
taken:
• The tool is actuated via the torque-wrench by a
diver.
• The tool is stripped-down, cleaned and lubricated
immediately to minimise corrosion.
5.9.3 SWi20/25TEEX
SWi20/25TEEX tools require a hydraulic hand pump that
is fitted with a sealed-bladder type reservoir system to
allows for sub-sea operation.
The SWi20/25TEEX is actuated by means of single-
acting spring-return hydraulic cylinder and can be used
sub-sea providing the following actions are taken:
1. The gauge and manifold are removed from the
hydraulic hand-pump and the coupler is fitted
directly to the pump outlet.
2. The tool is connected to the hydraulic hand-pump
whilst still top-side.
3. The pump release valve is fully opened and remains
open until the tool has descended to the working
depth. This will allow the pressure to equalise.
4. The tool is actuated via the hand pump by a diver.
5. Upon completion of works the release valve is
left in the fully-open position until the tool has
ascended to the surface.
6. The tool and pump are stripped-down, cleaned
and lubricated immediately to minimise corrosion.
Please note that SWi20/25TEEX cannot
be operated from top-side by use of a down-line. The
return springs in the hydraulic cylinders do not have
sufficient force to close the tool if used with a down-line
from a top-side pump, therefore the standard hydraulic
tools will not function correctly and may jam in place if
used in this configuration.
NOTICE
6. Storage
6.1 Recommended Storage
Equalizer Spreading Wedge tools should be stored in a cool dry place. Tools should always be cleaned, serviced
and lubricated prior to storage. Ensure that tools are stored in their designated packing cases.
6. Once bags have been closed and sealed DO NOT
re-open. Any visual inspections must be done with
closed and sealed bags. If bags are opened the
components will have to be dried, re-coated and
re-sealed in bags/shrink wrap.
7. Replace silica gel [100g] EVERY TIME
the case is opened.
NOTE: depending on moisture content of air, silica
gel should be changed weekly.
8. Visually inspect kits after 30-days and every 30-
days thereafter. Remember to replace silica gel
before closing case.
6.2 Long-Term Storage -
Maintenance Plan
1. Rub components down with a dry cloth to remove
moisture.
2. Coat EVERY surface and contact point with a
corrosion inhibitor. Where necessary, coat inside
and outside of component e.g. VC10
3. Nuts and threads must also be coated with a
corrosion inhibitor.
4. Once surfaces have been coated, seal
individual components in clear plastic bags
or clear vacuum bags or clear shrink wrap.
NOTE: bags/shrink wrap must be clear for visibility.
Take care when using shrink wrap that the tool is /
components are still easy to see.
5. Remove all or, where not vacuum sealed, as much
air from bags as possible.
