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.

WARNING

CAUTION

WARNING

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.
