1.0 Introduction
Overview
The Equalizer SWi5TE / SWi5TI has been
developed to assist in the spreading of all
flange joint types with a minimum access
gap of 4.0 mm (0.16”). The tool can
be used during pipework construction,
commissioning or during routine
maintenance.
The SWi tools have fewer moving parts
and no finger 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 flange joint. The SWi tools are
supplied with a swivel handle and safety
lanyard attachment as standard.
It is essential that the user familiarises
themselves with the contents of this
manual prior to using the tool.

2.1 Safety Precautions - Flange
Spreading Wedges
Failure to observe and comply with
the following precautions could result
in death or serious personal injury.
Property damage could also occur.
• Read and completely understand the
safety precautions and instructions
in this manual before operating the
Flange Spreading Wedges or preparing
them for use. Always follow all safety
precautions and instructions, including
those that are contained within the
procedures of this manual.
• Ensure all hydraulic components are
rated to a safe working pressure of
700bar (10 000psi).
• 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.
WARNING
CAUTION
NOTICE
WARNING

L4390 5
If alternative hydraulic pumps are used,
ensure that there are adequate systems
to limit the working pressure to 700 bar
(10 000 psi).
• Wear personal protective gear when
operating hydraulic equipment. Always
wear eye protection. Safety equipment
such as dust mask, non-skid safety
shoes, hard hats, gloves or hearing
protection (used as appropriate) will
reduced personal injuries.
• Applying pressure to a damaged hose
may cause it to rupture.
• Immediately replace worn or damaged
parts. Use only genuine Equalizer parts
from approved distributors or service
centres. Equalizer parts have been
engineered and manufactured to be fit-
for-purpose.
• To minimise risk of personal injury keep
hands and feet away from the tool and
workplace during operation.
• Do not handle pressurised hoses;
escaping oil under pressure can
penetrate the skin, causing serious injury.
Seek medical attention immediately if oil
penetration is suspected.
• Only pressurise complete and fully
connected hydraulic systems. Do
not pressurize systems that contain
unconnected couplers.
• 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.
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.
• Do not lift hydraulic equipment by
the hoses or couplers. Use only the
designated carrying handles.
• Lubricate tools as directed in this
manual prior to operation. Use only
approved lubricants of high quality,
following the lubricant manufacturers
instructions.
• Only use the designated anchor point
for fixing the lanyard. Do not attach the
lanyard to the plastic handle.
• Hydraulic equipment must only be
serviced by a qualified hydraulic
technician. For repair service, contact
the Enerpac Authorized Service Centre
in your area.
• Rope off working area and place
warning signs.
• The vibration total value to which this
tool is subjected does not exceed
2.5m/s2.

3.0 SWi Spreading Wedge Tool
Operation
3.1 General Guidance
Before attaching the tool ensure at least
two flange bolts remain in place. These
should be 180 degrees apart with their
nuts loosened suciently to enable flange
work to be carried out. Leaving these bolts
in place will help to reduce unwanted
lateral flange movement during flange
spreading (see fig.1).
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 (see fig.2).
Determine the flange joint access gap - a
minimum access gap of 4 mm (0.16”) is
required for the SWi5TE/SWi5TI tools. The
access gap is the clearance between the
surfaces onto which the wedge will apply
its spreading force (see fig. 3).
Place the tool into the access gap, with
the full width of the selected step fully
inserted up to the heel (see fig. 4).

3.2 Flange Spreading
Spread the flanges apart by actuating the
tool.
Spread the flanges apart by actuating the
tool. Consult the relevant sections of the
manual for tool-specific instructions on
how to activate 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 (see fig. 5).
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 (see fig.
6).
Fig. 4
Fig. 5
Fig. 6

L4390 7
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.
3.3 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.
3.4 Safety Blocks
Each tool is supplied with a Safety Block.
The Safety Block has been designed with
steps that match the spreading distance
of the SWi tools (see fig. 7).
The Stepped Block Kit contains a larger
Safety Block to cater for wider spreading
distances.
3.5 Flange Closure
Allow the flanges to return to their closed
position by gradually retracting the tool.
Consult the relevant section of the manual
for instructions on how to retract the 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 (see fig. 8).
DANGER
Fig. 7
Fig. 8
To use the smaller step of the safety block,
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.
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.
3.6 Stepped Blocks
A pair of Stepped Blocks can be supplied
as a kit item. These can be fixed to the
jaws (individually or in pairs) to increase
the eective jaw thickness and therefore
the maximum spreading distance.
Use of the Stepped Blocks also enables
the SWi5TE/SWi5TI Flange Spreader 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 eective jaw thickness
if required (see fig. 9).
Fig. 9

8L4390
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 (see fig.
10).
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.

the task.
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 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.
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
handle anchor holes for fixing the lanyard
(see fig 11 + 12).
Care should be taken when
using the lanyard to avoid entanglement
with body parts.

4.0 Tool Maintenance
4.1 Inspection
A thorough inspection should be
carried out prior to usage, storage or
transportation to ensure the completeness
and condition of the tool.
Inspection should include:
• Visual inspection of the outer parts of
the tool, checking for obvious damage,
degradation or missing parts.
• Visual inspection of the wedge-tip
(requiring tool actuation or jaw removal).
Damage to the wedge-tip is indicative
of tool over-load.
Cleaning and servicing should be
undertaken as required prior to the tool
being used, stored or transported.
4.2 Cleaning
To lightly clean the tool, wipe gently with
a damp cloth.
If more thorough cleaning is required (for
example following immersion in water)
carry out the following cleaning procedure:
• Strip the tool down.
• Clean the components using detergent,
following the manufacturer’s guidelines.
• Rinse the components to remove traces
of detergent.
• Dry the components thoroughly.
Inspect, service and lubricate the tool
immediately after the cleaning process.
4.3 Servicing
Replace missing worn or damaged parts.
Use only genuine Equalizer parts from
approved distributors or service centres.
Equalizer parts have been engineered and
manufactured to be fit-for-purpose.
Grease all moving parts by following the
Lubrication Procedure prior to usage,
storage or transportation.
If topping up or replacing hydraulic oil as
part of a service, use only premium quality
hydraulic oil of the grade 15cSt.
4.4 Lubrication Procedure
Apply grease following cleaning and
servicing, prior to usage, storage or
transportation. Never assemble and leave
a tool without following the greasing
procedure as degradation or damage may
occur.
Use only high pressure molybdenum
disulphide grease.
Remove the jaws as per the disassembly
instructions.
Apply grease liberally to the following
areas:
• The large flat surface on the underside
of the jaws.
• The internal flat surfaces in the square
cut-out in the jaws.
4.5 Storage & Transportation
Equalizer 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.

4.7 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.
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.
4.8 Sub-Sea Usage
The Equalizer range of HP hydraulic hand
pumps are fitted with a sealed-bladder
type reservoir system that allows for sub-
sea operation.
The SWi5TE 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 Equalizer HP350S/D hydraulic
hand-pump and the coupler is fitted
directly to the pump outlet (tools in this
configuration can be requested from
Equalizer).
2.The tool is connected to the Equalizer
HP350S/D 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 a SWi5TE tool cannot be
operated from top-side by use of a down-
line. The return springs in the hydraulic
cylinders do not have sucient 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.

5.0 SWi5TE Hydraulic Flange Spreading
Wedge
The SWi5TE Spreading Wedge uses
an external hydraulic pump to drive the
cylinder to advance the wedge and spread
the jaws.
5.1 SWi5TE Tool Capabilities
Spreading Force
With 700 bar (10 000 psi) of hydraulic
pressure applied, the tool can apply 6.3T
(63kN) spreading force on the 1st step,
up to 7.7T (77kN) spreading force on the
4th step.
Spreading Gap (See Section 3.9)
Using only the 1st step, the tool can spread
from 4.0mm to 29mm (0.16” - 1.14”).
Using all 4 steps, but without the stepped
blocks, the tool can spread from 4mm to
79mm (0.16” - 3.1”).
Using both steps on the stepped blocks,
the tool can spread 56mm – 101mm (2.2”
- 4”).
Fig. 13
5.2 SWi5TE Tool Function
Hydraulic Tool Operation
The SWi5TE 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.
Hand Pump Operation
Consult the Instruction Manual for the
Equalizer HP Hand-Pump.
Actuating The SWi5TE
Follow the SWi Spreading Wedge Tool
Operation instructions, using the following
instructions to actuate the SWi5TE 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.
Equalizer manufactures a twin-port hand
pump which can be used to actuate two
tools simultaneously.
Retracting The SWi5TE
Opening the release valve will de-
pressurise 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.
L4390 11

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.
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 o. Grip the refilling
plug with pliers and extract it by pulling
and twisting simultaneously. Ensure
the reservoir body is held down when
removing the refilling 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 refilling plug, wipe away any oil, and
reassemble by reversing the disassembly
process.

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.
Select advance, and pump the handle to
extend the piston around 30mm (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
(fig. 18).
Fig. 18
Fig. 19
Fig. 20
Replenish any missing hydraulic oil by
pouring into the Oil Fill hole until excess
spills over (fig.19 / fig.20).
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
