What This Manual Provides

The CPD 2000 RCD Drilling Machine Instruction Manual is structured around the actual working sequence of a reverse circulation drilling job. It opens with the RCD method itself — how air lifting drives the circulation, why the casing pipe is installed before drilling, how the cluster hammer and RCD cutter break rock, and how water is poured into the casing to maintain continuous circulation. From there it moves into the machine specification and then into the operating manual, which is where the daily pre-checks, hydraulic circuit checks, oil level inspections, test operation routines, and normal operation guides are found.

The drilling operating chapter is particularly practical. It covers the engine panel layout, the full control panel function list — feed, rotation, rotation speed control, mast tilting, rotary head tilting, rod cartridge tilting, rod push, pile clamp, deck base tilting — and then explains how pull down and hold back pressures are calculated and applied. The manual gives the actual cylinder dimensions used in the pull down and hold back force formulas, and it spells out the recommended rotation speeds and W.O.B. ranges for both the cluster hammer and the RCD cutter. The air supply sequence is laid out step by step, from lifting the cluster off the hole bottom through to opening the second, third, and fourth ports, rotating the head, feeding down slowly, and monitoring flushing water flow.

For maintenance, the manual includes a daily checking table, a repair and checking standard table covering hydraulic oil, hydraulic pump, pressure gauges, pressure control valves, and flow control valves with inspection frequencies and maintenance standards. The pressure control valve and flow control valve troubleshooting sections give causes and remedies for common hydraulic faults. The disassembly cautions section covers safe handling of hydraulic components, including checking for residual pressure before loosening fittings, protecting disassembled parts from rust, and replacing O-rings and packing on reassembly.

Engine Coverage — Doosan PU126Ti and DE12T Series

A substantial part of the manual is the engine operations and maintenance guide, which covers the Doosan PU126Ti, DE12T, P126TI, P126TI-1, and P126TI-II engines. This section includes full mechanical specifications, valve timing, fuel system data, lubrication system data, cooling system data, electrical system data, and performance curves. It also includes the safety regulations for operating and maintaining the engine, the commissioning and break-in procedure, periodic inspection and maintenance schedules, valve clearance adjustment, injection timing adjustment, cylinder compression pressure testing, V-belt tension checking, turbocharger maintenance and clearance measurement, injection nozzle maintenance and testing, fuel injection pump data, and a special tool list.

The engine section is written for the technician who will actually be adjusting valves, timing injection, testing compression, or servicing the turbocharger. It includes the torque values for cylinder head bolts, connecting rod bearing cap bolts, crankshaft main bearing cap bolts, flywheel fixing bolts, and injection pump components, along with the tightening sequences and angle-torque procedures where applicable.

Hydraulic and Mechanical Diagrams

The reference drawings include a full hydraulic diagram for the CPD-2000, showing the pump configuration, valve blocks, rotary head circuit, feed circuit, mast tilting, rotary head tilting, rod cartridge tilting, rod push, pile clamp, and deck base tilting circuits with pressure settings. The lay out drawings show the machine from multiple angles with dimensions, and the rotary head assembly drawings provide sectioned views of the rotary head for maintenance reference.

Who This Manual Is For

This CPD 2000 RCD Drilling Machine Instruction Manual is for the operator, drilling supervisor, maintenance technician, or workshop that services the CPD 2000 RCD rig. It covers the complete machine — the drilling method, the hydraulic controls, the drilling parameters, the engine, and the maintenance schedule. Because the manual is tied to serial numbers 2012-004 and 2012-005, it is directly applicable to those two machines, but the procedures and specifications apply to the CPD 2000 model generally.

Why This Manual Matters

RCD drilling is a large-diameter method where the air lifting circulation, the casing pipe, the cluster hammer or RCD cutter, and the pull down / hold back pressures all have to be balanced correctly. If the drilling speed is too high in soft ground, the tool can flounder. If the pull down force is wrong for the rock condition, the cutter wears unevenly or the hole deviates. If the air supply sequence is not followed, the hammer can jam or the flushing water can stop. The manual gives the specific pressure calculations, speed ranges, and step-by-step sequences that keep the drilling operation stable. On the maintenance side, the hydraulic system runs at 250 bar operating pressure and up to 350 bar maximum, so correct troubleshooting of the pressure control and flow control valves is essential to avoid damage to the pumps, motors, and cylinders. The engine section covers the Doosan PU126Ti and DE12T series with the torque values, clearances, and adjustment procedures needed to keep the power pack reliable.
