1 Introduction
This document covers the HDD40 Horizontal Directional Drilling System. The system connected to the drill using the following:
•HDD40 Horizontal Directional Hammer
•Support Station
•Compressor
•Water supply
The basic setup is shown below.
The Installation and Operation section will deal with setup of the system and basic operation. Following that we will deal with
disassembly and servicing. When dealing with the HDD40 in the service section we will separate it into two parts: Firstly the Horizontal
Directional Drilling hammer component that makes drilling possible and secondly the Sonde housing component that makes steering
possible.

2 Installation and Operation
2.1 Safety
Be sure to work safely at all times. Wear protective clothing and safety equipment and observe all safety regulations as prescribed by
your employer, Government, or the site on which you work. Do not wear loose clothing that may get caught in rotating parts and cause
serious personal injury. Remember that a “Horizontal Down-the-Hole” percussive hammer emits noise and you should therefore take
every precaution to safeguard your hearing against damage by using proper ear protectors.
Use eye protection at all times. Rock chips and dust which may be discharged from the face of the bit or bore hole at high velocities
and can cause severe injury. Hammers can be heavy – Always use proper and approved lifting equipment and take every precaution
to safeguard yourself against injury. Keep hands clear at all times – Beware of getting fingers trapped between the chuck and bit and
do not use hands or feet to clear the top of the borehole at any time. Other safety advice is given throughout this document which you
are advised to read.
2.2 Set up of HDD40 Hammer and Sonde
2.2.1 Storage
If you intend to store the HDD40 Hammer we recommend that ½ pint (¼ litre) of good quality rock drill oil be poured into the hammer to
protect it. To do this the hammer section should be unscrewed from the Bent Sub and then the oil should be poured into the top of the
hammer and let flow down into the piston chamber of the hammer to coat the parts and protect them from rust and corrosion. Once
completed the bent sub and the Sonde Housing can be reinstalled. Ensure that the thread protector and chuck cap are fitted to keep
debris out and to prevent oil leakage. Store the hammer horizontally in a clean dry place.
2.2.2 Setup of Sonde
When the HDD40 is supplied it will contain the necessary parts for the successful installation of a commercial Sonde. The two main
types of Sonde are dealt with in this manual: DCI Sonde and Sub Sight.
2.2.2.1 Installation of DCI Sonde
The following series of picture will detail the installation of a DCI Sonde into the HDD40. The same procedure should be used for
servicing or changing the Sonde at a later date.
STEP1 STEP2
Unscrew and remove Sonde Housing Backhead from the
Sonde Housing Sleeve Insert and screw the Sonde Line Up Tool into the Sonde
Carriage retrieval cap and pull out the complete Sonde
Carriage assembly.
Mincon – “Leaders in Rock Drilling Technology” Page 5
Step3 Step4
Unscrew and remove the Sonde Carriage Locating Cap,
Springs and the DCI Adapter from the Sonde Carriage (At
Opposite end to the Sonde Carriage retrieval cap)
Loosen and remove with the Torque Wrench the DCI Adaptor
Locating cap from the tube. The correct end has locating
dimple.
Step5 Step6
Insert and push the DCI Sonde into the tube. Fit the DCI Adaptor Locating cap onto the DCI Sonde
ensuring the Locating cap’s intrical key is seated correctly in
the Sonde Keyway.

Step7 Step8 Step9 Step10
Push the Sonde in the rest of the way
and screw the DCI Adaptor Locating
Cap in and tighten snugly with the
Torque wrench.
Insert first spring into the
Sonde Carriage. Insert the DCI Adaptor into
the Sonde Carriage Insert the second spring in to
the Sonde Carriage.
Step11 Step12 Step13
Align the Sonde Carriage Locating Cap
Groove with the DCI Adaptor Locking Dimple
and push the cap on so that the hex socket
of the Carriage Locating Cap fits over the
DCI Adaptor and then screw the Carriage
Locking Cap in place
Push the Sonde carriage into the Sonde
Housing Sleeve with the Sonde Carriage
Locating cap entering first.
Screw the Retrieval bar into the Sonde
Carriage and push forward until it stops.
Turn gently until you feel the Sonde
Carriage go forward and the Sonde
Carriage Locking Cap groove seats
over the Sonde Carriage Locating pin
(See Step 14 for details of the pin).

Step14 Step15
Above picture shows the Sonde Carriage Locating Pin. The pin is in the
Bent Sub set so that the Sonde will be aligned correctly in the twelve
O’clock position.
Insert and screw the Sonde Housing Backhead in place.

2.2.2.2 Installation of Sub-Sight Sonde
The procedure for installing a Sub-Sight Sonde is the same as the DCI Sonde except Step 3 through Step 7 are replaced with the
following:
Step1 Step2 Step3
Above picture shows the end of the Sub
Sight Sonde that will receive the Sub Sight
Locating adaptor.
All screws to be inserted should have
the threads coated with a thread lock
compound.
Fit the first half of the Sub Sight adaptor to
the Sonde and tighten.
Step4 Step5 Step6
Fit the second half of the Sub Sight
adaptor to the Sonde and tighten. Then fit
the assembly locking screw as shown
above.
Fit the top section of the Sub Sight
locating assembly and tighten. Unscrew the other end off the Subsight and
replace with the Adaptor end cap shown
above. Once completed the Sonde
assembly can be installed from Step 8
above.

2.2.3 Installation of Bit
The following sequence of instructions is used to correctly fit the bit in the correct orientation for drilling.
Step1 Step2
Unscrew and remove the Chuck from the Hammer. Remove Bit Retaining Ring from the Chuck and screw the
Chuck back in place.
Step3
Insert the bit into the Chuck so that the Bent Sub wear carbides are aligned in a straight line with the three bit wear carbides as
illustrated above.
Mincon – “Leaders in Rock Drilling Technology” Page 10
Step4 Step5
Unscrew the Chuck and Bit from the hammer making sure that
the bit does not come out of the Chuck. Insert the Bit Retaining Rings back into the Chuck as shown
above making sure that the Bit does not come out of the
Chuck.
Step6
Push the Chuck forward to secure the Bit Retaining Ring in place against the rear splines. Screw the Chuck, Bit and Bit
Retaining Rings in place.
2.3 Setup and Operation of Support Station
Prior to operation the Support Station must be setup to ensure that correct and safe operation of the equipment is carried out.
CAUTION – For safe working conditions during operation of the equipment it is essential to have received the appropriate training prior
to starting up the equipment.
