Page 3: Introduction
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. -
Page 4: Installation And Operation
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. - Page 5 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. Mincon – “Leaders in Rock Drilling Technology” Page 5...

Check the in-line filter on the pump periodically for debris. In colder conditions antifreeze the pump and drain the 40 foot water hose and clean and empty the in-line filter to protect from freezing while not operating the drill. Mincon – “Leaders in Rock Drilling Technology” Page 14... -
Page 15: Commissioning Of Hammer
Insufficient thrust pressure will make the hammer drill erratically and less efficiently and cause premature wear to the bit and chuck splines with likely damage to the hammer components and threads. Mincon – “Leaders in Rock Drilling Technology” Page 15... - Page 16 The Air Consumption of the hammer is as per the chart below. The chart represents operating pressure and equivalent air consumption at sea level with an ambient temperature of 68°F (20°C). Mincon – “Leaders in Rock Drilling Technology” Page 16...

Page 17: Servicing
Opening Chuck and Backhead The threads used in Mincon Hammers are right hand threads. Proper tools and break-out systems should be used at all times to dismantle HDD hammers, otherwise damage may be caused to the components which could result in eventual failure or affect the performance of the Hammer. -

Place the bit retaining rings in and screw the chuck in place. Again make sure to have the thin end of the bit retaining rings at the blow tube end of the bit. Mincon – “Leaders in Rock Drilling Technology” Page 18... - Page 19 This gap should be between 0.015” and 0.030”, and can be measured using a feeler gauge. If the gap is less than the minimum, then the lock ring will need to be replaced. Protect the hammer as earlier described by internal lubrication.
