2.1 Safety Precautions
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 minimized by using the Enerpac
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).
• 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 reduce personal injuries.
• Applying pressure to a damaged hose may cause it to
rupture.
• Immediately replace worn or damaged parts. Use only
genuine Enerpac parts from approved distributors or
service centers. Enerpac parts have been engineered
and manufactured to be fit-for-purpose.
• To minimize risk of personal injury keep hands and feet
away from the tool and workpiece during operation.
• Do not handle pressurized hoses; escaping oil under
pressure can penetrate the skin, causing serious injury.
Seek medical attention immediately if oil penetration is
suspected.
• Only pressurize complete and fully connected hydraulic
systems. Do not pressurize systems that contain
unconnected couplers.
WARNING
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.
• Lubricate tools as directed in this manual prior to
operation. Use only approved lubricants of high quality,
following the lubricant manufacturers instructions.
• 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.
• To help ensure proper operation and best performance,
use of Enerpac oil is strongly recommended.
• The vibration total value to which this tool is subjected
does not exceed 2.5m/s².
CAUTION
NOTICE

L4388 .5
A fresh hold on a new step can then be chosen
to open the joint further if required.
The operator must ensure that the wedge and
the 4 slide pins are lubricated each and every time the
equipment is used. This will give maximum eciency and
prolong the working life of the wedge.
To minimise risk of personal injury keep
hands and feet away from the tool and workpiece during
operation.
The handle of the wedge is there to stop
operators holding spread plates as the wedge is retracted.
This will stop fingers becoming jammed between plates.
Never hammer or force wedge into the access
gap.
When using FSC14, only use the designated
handle anchor holes for the lanyard (FSC1).
Care should be taken when using the lanyard
(FSC1) to avoid entanglement with body parts.
Do not over pressurize the pump as this may
cause injury to personnel.
Do not use a handle extension on any pumps.

3.0 OPERATING INSTRUCTIONS
It is recommended that two wedges be used in tandem.
This will give an even spread to the joint. The wedges
should be set at 180˚ apart (see fig. 1).
The wedge should be used only if the full step area is
located into the gap, and the object requiring spreading
is in contact with the heel of the next step (see fig. 2).
When operating the FSC14, ensure the air vent is not
obstructed in any way as this will result in a vacuum
within the system and the wedge will not advance.
Ensure wedge is fully located on the step
selected to spread (see fig. 2 and 3).
Minimum hold should be 15mm (0.59in).
The safety block (see fig. 4) should be inserted
into the joint and the pressure released onto the block.

4.0 USE OF STEPPED BLOCKS
The maximum opening of the wedge spreaders can be
increased from 61 to 81mm (2.40 to 3.19in) when used in
combination with the optional FSB1 stepped blocks (see
fig. 5 and 6)
.
The FSB1 give more access to replace ring joints, metal
seals and cleaning of flange surfaces. The use of stepped
blocks reduce the amount of penetration of the wedge
point into the joint.

Lubrication
To properly maintain the tool it is important to grease all
moving parts regularly (see fig. 10).
These are:
• Pushrod (No. 9)
• Jaws (No. 13)
• Thrust Bearing Set (No. 3)
Numbers 9 and 13 respectively must be greased each
time the tool is used and No. 3 should be greased at least
once per month.
Lubricating the Pushrod
Smear grease on the Pushrod (No. 9) while the Wedge
(No. 1) is in the retracted position. This will enable the
screw to turn freely and give maximum spreading at the
tips.
Lubricating the Jaws and Slots
A Grease Nipple (No. 17) is supplied with the tool located
on the Handle (No. 7) for easy storage. The Grease Nipple
should be removed from the Handle and inserted, in turn,
into each of the Jaws, and a grease gun used to pump
grease into the Wedge. The Grease Nipple insertion point
is shown on fig. 11. Grease should also be smeared into
the Slots positioned at the side of each Jaw to allow the
Pins (No. 11) to slide freely as a load is applied to the
Wedge.
7.0 INSPECTION, MAINTENANCE & STORAGE
• Keep the spreading wedge clean. Remove any loose
dirt or dust from exterior surfaces.
• Periodically check the spreading wedge for cracks,
wear and damage. Replace any cracked, worn or
damaged parts immediately.
• Periodically check hydraulic components for loose
connections, oil leaks and other obvious problems.
Replace any leaking, worn or damaged components
immediately.
• Store the spreading wedge in a clean, dry and secure
location. Keep the stored spreading wedge and hoses
(if present) away from heat and direct sunlight.
• FSH14 only:
- To prevent dirt entry, install dust caps on hydraulic
couplers after disconnecting the hydraulic hose from
the spreading wedge.
- Change the pump hydraulic oil at the recommended
interval shown in the pump instruction sheet. Change
the oil immediately if contamination is suspected.
• For repair service, contact an Enerpac Authorized
Service Center. Inspection and repairs should be
performed only by an Enerpac Authorized Service
Center or other qualified hydraulic tool service facility.
