1.0 Health and Safety
1.1 General
Personnel using this manual to perform maintenance should have basic training in the following
disciplines:
• Manual handling
• MSDS and COSHH
• Use of workshop equipment
• Use of hand tools (PUWER)
Other basic courses may be required depending on regulations in the location/region that the
equipment is being used.
Safety is everyone’s responsibility, anyone can stop an operation should they deem an act unsafe no
matter what their position is within an organisation.
By following this document, using hand tools correctly, and following working practices the risk of
injury will be reduced to negligible.
CAUTION
• Read service manual before operating
• Observe all safety precautions
• This system is capable of producing high fluid pressures - appropriate considerations are
required
• Check that only qualified personnel are in immediate area around equipment
• Suitable PPE must be worn at all times
• Do not try to tighten or loosen connections under pressure
• Do not weld, file or use metal stamps on the pressure equipment - these can create cracks
which could result in structural damage/failure
• Do not attach anything to this equipment unless you are sure of its pressure rating
• Watch for trapped pressure. Bleed off fully before breaking down tool
Observe the maximum allowable operating pressure of all system components.
Observe the operating conditions of components.
Never stand under suspended loads or in the lifting area!

1.2 Precautions
A competently deemed person must be in attendance when performing maintenance on this
equipment. To be deemed competent the individual should have received training on the subject
followed by being observed performing the tasks to the required standard over a time period.
Personnel competence criteria are defined by the technician’s employer.
Hand tools that have not been maintained can lead to accidents, therefore all equipment must be
inspected before use.
1.3 PPE
Basic personal protective equipment must be worn at all times during the maintenance procedures.
There may be the need to use more specific items when using specialised tools, these rules must be
followed to reduce risk of injury. Basic items deemed by Hunting for maintenance personnel are as
follows:
• Safety footwear
• Safety glasses
• Hand protection
• Long sleeved coverall
Some workshop regulations deem that hard hats / bump caps and hearing protection must be worn in
maintenance shops, these will be defined by the policy owner. If working in the field, all of the above
items may need to be worn at all times, once again, this is defined by the company / client’s policies.
1.4 Pressure Control
Working with pressure exposes personnel to one of the greatest risks in our industry hence all
personnel must have received formal training on this subject. Company / Client pressure guidelines
must be adhered to with no deviation from the policies. Personnel performing pressure tests must
observe regulations concerning pressure test bays and operating instructions for pumps. All equipment
must be rated for the pressure being applied and certified.

4.0 Operating Procedure
Clean and inspect all parts during disassembly. Replace damaged or worn parts where necessary.
Item numbers called out in this document correspond with assembly drawings in Appendix I.
• The hydraulic Yoke fits directly into the recesses of the Dimple Jig and when fully engaged is
aligned by flats at the root of each recess
• The front of the Yoke jaws are relieved, this allows the Yoke to be rotated about the Dimple
Jig without its complete removal
• With the Dimple Jig fully engaged in the Yoke the assembly is ready for use
• Attach a hydraulic power supply fitted with a 10K pressure gauge
• Check whether the Yoke is engaged above 1 or 2 Dimple Pins, before applying hydraulic
pressure
o To make 1 indentation hydraulic pressure required is 3000 psi
o To make 2 indentations hydraulic pressure required is 6000 psi
• Hydraulic pressure must never exceed 7500 psi
• Release hydraulic pressure immediately the indentation has been made
• Pull the Yoke back until the Dimple Jig sits in the relief, rotate the Yoke through 45° and
push it back into the fully engaged position ready to make the next indentations
• Follow the same procedure until all the dimples have been formed
• Remove the Yoke, release the Jig Alignment Screw and the Locking Screw and remove the
Dimple Jig
• Check the connection to ensure all the indentations have been formed before the connector is
used

5.0 Assembly Instructions
Clean and inspect all parts prior to assembly. De-burr any rough edges and buff all surfaces where
required. All threads should be coated with an anti-seize compound prior to make-up.
Item numbers called out in this document correspond with assembly drawings in Appendix I.
• Prepare the Tubing using the ICRS
• With the O-Rings installed push the connector into the tubing until the joint is flush
• Note the position of the Dimple Jig alignment hole, which is situated on the outer diameter of
the connector, adjacent to the Tubing End
• Fit the Dimple Jig over the connector and align and lock the Jig Location Screw
Note: The Jig Location Screw must be tight and flush with the outside of the Jig to ensure
correct alignment.
• Tighten the second Screw, which is located directly above the Jig Location Screw. This screw
secures the Jig to the tubing
• It is recommended to dimple the first pin on the same side as the Jig Locating Screws, then
loosen the Locating Screws and continue with the installation of the connector
NOTE: FAILURE TO COMPLY WITH STEP 6 MAY RESULT IN DAMAGE TO THE
COILED TUBING CONNECTOR.
