INTRODUCTION
The Equalizer™ SWi Innovative Range of Flange
Spreading Wedge tools has been developed to assist in
the spreading of all ange joint types with a minimum
access gap of 6.0 mm (0.24”). The tools can be used
during pipework construction, commissioning or during
routine maintenance in potentially explosive atmospheres
and conform with the EU directive 2014/34/EU.
The SWi tools have less moving parts and no nger pinch
points. The tools have been developed to increase the
spreading distance on each step while gaining easier
access between any remaining stud-bolts within the ange
joint. The SWi tools are supplied with a swivel handle,
safety lanyard and stepped block attachment as standard.
For the external hydraulic ange spreading wedge kits
ATEX rated hoses of a variety of lengths can be provided.
It is essential that the user familiarises themselves with
the contents of this manual prior to using the tool.

2.5
HAZARDS
WARNING: ensure all hydraulic components
are rated to a safe working pressure of 700 bar
(10 000 psi).
WARNING: Do not overload equipment. The
risk of hydraulic overloading can be minimised
by using the Equalizer Hand Pump, which has a
factory-set safety valve preventing the safe
working pressure being exceeded.
If alternative hydraulic pumps are used, ensure
that there are adequate systems to limit the
working pressure to 700 bar (10 000 psi).
CAUTION: ensure components are protected
from external sources of damage, such as
excessive heat, ame, moving machine parts,
sharp edges and corrosive chemicals.
CAUTION: 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.

FLANGE SPREADING
Spread the anges apart by actuating the tool. Consult the
relevant section of the manual for tool-specic 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 ange joint.
Ensure the full width of the selected Safety Block step is
fully inserted before gradually retracting the tool until the
ange load has been applied to them.
The wedges can then be retracted fully and inserted
again, using the next step. In this way the ange joint can
be iteratively opened further until the required spread is
reached.

TOOL OPERATION
3.1
GENERAL GUIDANCE
Before attaching the tool ensure at least two ange bolts
remain in place. These should be 180 degrees apart with
their nuts loosened sufciently to enable ange work to
be carried out. Leaving these bolts in place will help to
reduce unwanted lateral ange movement during ange
spreading.
Prior to spreading, an assesment 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.
Determine the ange joint access gap - a minimum access
gap of 6 mm (0.24”) is required for the SWi tools. The
access gap is the clearance between the surfaces onto
which the wedge will apply its spreading force.
6.0 mm (0.24”)
MINIMUM
ACCESS GAP
Place the tool into the access gap, with the full width of
the selected step fully inserted up to the heel.

SWi12/14TMEX; SWi20/25TIEX; SWi20/25TEEX FLANGE SPREADING WEDGES 7
3.5
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.
3.6
STEPPED BLOCKS
The SWi Range of Flange Spreader tools are supplied
as standard with a pair of Stepped Blocks. These can
be xed 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 Flange
Spreaders 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.
3.3
FLANGE WORK
DANGER: Do not rely upon hydraulic systems
for supporting the access gap during ange
work. Do not allow ngers, hands or other body
parts into the space created between the
anges.
3.4
FLANGE CLOSURE
Allow the anges to return to their closed position by
gradually retracting the tool. Consult the relevant section of
the manual for tool-specic instructions on how to retract
each tool. Before the tool has fully retracted, insert the
Safety Blocks into the ange joint. Ensure the full breadth
of the selected Safety Block step is fully inserted, before
gradually retracting the tool until the ange load has been
applied to them.
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 ange joint can be
progressively closed.
As the ange 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.

3.8
LANYARD
The 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 xed 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 x 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.
CAUTION: Only use the designated anchor
point for xing the lanyard. Do not attach the
lanyard to the plastic handle.
DANGER: Care should be taken when using
the lanyard to avoid entanglement with body
parts.
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.
15.0 mm (0.59”)
MINIMUM HOLD
3.7
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. Unclip the spiral ring and remove the anchor
point and handle. Special caution should be exercised
when working with a tool in this conguration. Replace
the handle immediately following the task.

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.
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 ne scale aligns with
40 N·m on base scale; now turn slightly further until the 6
on the ne scale aligns with the central line.
Setting an imperial torque (in ft·lb) is done in exactly the
same way.
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.

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 (-).
ACTUATING THE SWi20/25TIEX
Follow the SWi Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi20/25TIEX tool in particular:
When advance (+) is selected, pumping the handle will
advance the cylinder and spread the jaws.
RETRACTING THE SWi20/25TIEX
Selecting retract (-) will depressurise the cylinder and
cause it to retract under the force of its internal spring.
The handle does not need to be pumped to retract the

Select advance (+), and pump the handle to extend the
piston around 30 mm (1.2”). Remove the Oil Fill Screw
using an appropriate hex key, ensuring the tool is on its
side with the Oil Fill facing upwards (top photo).
Replenish any missing hydraulic oil by pouring into the Oil
Fill hole until excess spills over (middle photo).
Sit the tool with the wedge facing uphill (and the open Oil
Fill hole still facing upwards) on a gentle slope, around 30
degrees from horizontal.
Very slowly move the selector from advance (+) to retract
(-), and wait for the tool to fully retract (lower photo).
Replace the Oil Fill Screw.
Repeat this procedure 3 times.

SWi20/25TEEX TOOL FUNCTION
HYDRAULIC TOOL OPERATION
The SWi20/25TEEX Spreading Wedge uses a hydraulic
cylinder to advance the wedge and spread the jaws.
The hydraulic pressure is applied using an external hand
pump, enabling accurate control of the force applied.
ACTUATING THE SWi20/25TEEX
Follow the SWi Spreading Wedge Tool Operation
instructions, using the following instructions to actuate
the SWi20/25TEEX tool in particular:
When the Hand-Pump release valve is closed, pumping
the Hand-Pump handle will advance the cylinder and
spread the jaws.
When using multiple tools, ensure that the spread of all
tools correspond to keep the spreading force balanced.
RETRACTING THE SWi20/25TEEX
Opening the release valve will depressurise the cylinder
and cause it to retract under the force of its internal
spring. The handle does not need to be pumped to retract
the tool.
When using multiple tools, exercise caution while retracting
to keep the spreading force balanced as the gap is closed.
AIR-LOCK RELIEF
If full pressure is not achieved an air-lock may be present
in the hydraulic system. The following procedure can be
executed to relieve any air-locks.
Connect the hand pump to the tool with the hydraulic
hose. Close the release valve on the pump, and prime the
pump until the hydraulic cylinder is fully extended and a
small pressure is achieved.
With the hand pump elevated above the level of the tool,
and the tool in an upright position, open the hand pump
release valve causing any air that is within the system to
be forced up through the pump and vented into the oil
reservoir.

and spread the jaws.
7.1
SWi20/25TEEX TOOL CAPABILITIES
SPREADING FORCE
With 700 bar (10 000 psi) of hydraulic pressure 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 3.9)
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”).

Repeat this process three further times to ensure that
all air is removed from the system. The tool should now
reach full working pressure
Disconnect the hand pump from the hydraulic hose,
grip the baseplate of the hand pump body in a vice with
the pump body vertical and the main handle at the top.
Remove the four nuts holding the main handle and lift off.
Grip the relling plug with pliers and extract it by pulling
and twisting simultaneously. Ensure the reservoir body
is held down when removing the relling plug as pulling
up on the reservoir body will release the bladder within,
and oil may spill out. Fill the reservoir to the top with a
premium quality hydraulic oil of the grade 15 cSt. Reinsert
the relling plug, wipe away any oil, and reassemble by
reversing the disassembly process.
