INTRODUCTION
The Equalizer MG7TM MINI-GAP FLANGE SPREADER is
designed to aid the safe separation of ange faces. This
system has a unique ability to break ange joints with a
2mm gap between the ange faces. The tool is designed
to separate anges while applying an immense amount of
force to the correct point of separation.
The use of these instructions will promote safe use, and
maximise the service life of the tools.
It is essential that the user familiarises themselves with
the contents of this manual prior to using the tool.
This manual contains information for the following tools:
• MG7TM Mini-Gap Flange Spreader
The Equalizer MG7TM Mini-Gap Flange Spreader:
• Offers a safe and reliable working method
• Provides 6.8 tonnes of spreading force
• Separates ange faces with a gap of 2mm or greater
• Is lightweight and easy to use

SAFETY INFORMATION
2.1
GENERAL SAFETY
These instructions cover the safe operation and
maintenance of THE EQUALIZER MG7TM MINI GAP
FLANGE SPREADING tools. The use of these tools should
be as part of a broader task-based risk assessment, which
should be carried out by the operation supervisor or other
competent person.
Failure to comply with the safety information contained
within this manual could result in personal injury or
equipment damage. Read all instructions, warnings and
cautions carefully, and follow all safety precautions.
The safety of the operator, any assisting personnel and
the general public is of paramount importance. Always
work in accordance with applicable national, local, site &
company-wide safety procedures.
2.2
PERSONNEL COMPETENCY
Only personnel deemed competent in the use of mechanical
and hydraulic equipment should use these tools.
2.3
DISCLAIMER
Equalizer cannot be held responsible for injury or damage
resulting from unsafe product use, lack of maintenance
or incorrect product and/or system operation. If in doubt
as to the safety precautions and applications, contact
Equalizer using the contact details at the back of this

DEFINITION OF TERMS
A CAUTION is used to indicate correct operating or
maintenance procedures and practices to prevent damage
to, or destruction of equipment or other property.
A WARNING indicates a potential danger that requires correct
procedures or practices to avoid personal injury.
A DANGER is only used when your action or lack of action
may cause serious injury or even death.
DO: an illustration showing how the tool should
be used.
DON’T: an illustration showing an incorrect way to
use a tool.
2.5
HAZARDS
WARNING: ensure all hydraulic components are
rated to a safe working pressure of 700bar
(10,000psi).
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.
WARNING: Applying pressure to a damaged hose
may cause it to rupture.
WARNING: 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 t-for-purpose.
DANGER: To minimise risk of personal injury keep
hands and feet away from the tool and workpiece
during operation.
WARNING: Always wear suitable clothing and
Personal Protective Equipment (PPE). 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.
WARNING: Only pressurize complete and fully
connected hydraulic systems. Do not pressurize
systems that containt unconnected couplers.
CAUTION: Do not lift hydraulic equipment by the
hoses or couplers. Use only the designated carrying
handles.
CAUTION: Lubricate tools as directed in this
manual prior to operation. Use only approved
lubricants of high quality, following the lubricant
manufacturers instructions.
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.

TOOL CAPABILITIES
Spreading Force: 6.8 T (68 kN) per tool
It is recommended that tools are used in pairs giving
2 x 6.8 = 13.6 T (136 kN)
The tool achieves a spreading distance of 27mm from
a 2mm gap. At a 7mm gap the tool steps down the
spreading force applied from 6.8 tonnes to 3.9 tonnes.

INSTALLATION AND OPERATION
Before attaching the tool, ensure at least two
ange bolts remain in place, 180 degrees apart,
with nuts loosened sufciently enough for
ange work to be carried out. These bolts will
reduce lateral ange movement during ange
spreading and will help support the unit.
Do not extend the handle or use the smaller spreading bar
as an extension bar.
Be aware of the dangers of breaking sealed ange joints.
Ensure that relevant risk assessments have been carried
out for the task and your company procedures must be
followed at all times.
TOOL CONFIGURATION 1

TOOL CONFIGURATION 2
Small
Ø 16mm (0.63”)
Spreading bar
Choose the suitable conguration for the size and class of
ange joint you wish to separate.
See the application charts found at the end of of this
manual.
The spreading bars are designed to only t the correct
ange specication. No two spreading bars can t the
same stud hole.
The ange bolting should be disassembled as
per your company’s procedures and risk
assessment.
Place the tool over the ange joint and align with the
desired stud hole.
Engage the spreading bar through the leg of the
tool and the ange stud hole.
Do not hammer or use excessive force to t
the spreading bar. The bar should be tted by
hand.

FLANGE SPREADING AND SEAL REMOVAL
Turn each opposing tool a half turn at a time until the
desired gap is achieved. Care must be taken to ensure the
force is applied evenly.
The maximum spreading distance for the MG7TM is
27mm.
27mm
MAX
Take care to ensure the spreading bar is correctly tted
through the second leg of the tool. Check
the wedge is positioned in the gap between the
ange faces.
It is strongly recommended that two MG7TM Tools are
used on the ange joint positioned 180 degrees apart.

MG7TM TOOL MAINTENANCE
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.
Cleaning and servicing should be undertaken as required
prior to the tool being used, stored or transported.
CLEANING
At regular intervals, and specically after being exposed
to salt water, Mini-Gap mechanical tools should be
dismantled and lubricated as follows:
1. Lay the tool on a bench or at surface with the right
hand side face down.
2. Pull the spreading bar out of the tool.
