DANGER:
THIS MANUAL PROVIDES INFORMATION AND DATA FOR THE MAINTENANCE AND OPERATION OF THIS MACHINE. ALL ELECTRICAL EQUIPMENT MUST BE SERVICED BY QUALIFIED INDIVIDUALS WHO HAVE BEEN PROPERLY TRAINED TO WORK WITH HIGH VOLTAGE SYSTEMS, AND/OR VARIABLE FREQUENCY AC DRIVES. FAILURE TO COMPLY COULD RESULT IN PERSONAL INJURY OR DEATH.
DANGER:
DO NOT ATTEMPT MECHANICAL OR ELECTRICAL MAINTENANCE ON THIS MACHINE WITHOUT A FULL UNDERSTANDING OF EACH COMPONENT’S OPERATION AND FUNCTION. COMPONENTS UTILIZING ELECTRICAL POWER, AIR PRESSURE, HYDRAULIC PRESSURE AND COMPRESSION OR TENSION SPRINGS FOR OPERATION MUST BE DEACTIVATED AND ISOLATED PRIOR TO DISASSEMBLY.
The FEEDER CABLE must contain a provision for a ground connection, especially whenever 2,300 volts or greater are used. At the substation, the power line must terminate (see paragraph on ground circuits) to a suitable permanent ground. At the machine, the power line must securely terminate through a bolted connection to the machine frame. This provides a constant ground for the machine and its electrical equipment. Failure to provide this adequate ground endangers employees and equipment.
THE NEED FOR A POWER LINE GROUNDING CIRCUIT ADEQUATE FOR THE MACHINE CANNOT BE OVEREMPHASIZED. Without a good grounding system, high voltages exist between the machine and the ground. The portable trail cable and power lines supplying electric energy to the machine must have a ground wire, ample in capacity, running parallel to the main wires over the entire distance from the transformer to the machine. A suitable grounding system must be used at the transformer. Consult your local electrical supplier for details.
DANGER:
DUE TO THE INHERENT DANGERS IN THE OPERATION OF HIGH VOLTAGE ELECTRICAL EQUIPMENT, A SAFE GROUNDING SYSTEM IS REQUIRED THAT INCLUDES GROUND CONDUCTORS IN THE CABLE, A NEUTRAL GROUNDING RESISTOR, AND RELATED RELAYS AND SWITCHGEAR. A GROUND CONTINUITY CHECK SYSTEM IS ALSO RECOMMENDED.

COMPONENT SYSTEMS
PROPEL MACHINERY:
The propel system of the machine is a chainless hydraulic drive system which will allow the separate tracks to counter-rotate. This capability provides the machine with the capacity to turn completely around within it’s own length. Each track is driven by a hydraulic motor and a planetary gearbox equipped with a hydraulically released, spring activated brake. The machine is capable of 2 different propel speed ranges. The lower speed range is used for maneuvering in close spaces while the high speed range is used for tramming in open areas, over long distances.
MAIN FRAME AND DECKS:
The machine main frame is of welded box type construction with integrally placed mast supports and jack towers.
MAST:
The machine is a fabricated structure of steel tubes and formed plates. The major structure is composed of vertical tubes welded together with back bracing. The mast functions to provide the mounting and guide for the equipment required to operate the drilling function of the machine. The mast is capable of being positioned at any 5o increment within it’s operating range from 65 degrees through 90 degrees (vertical). The mast can be raised and lowered by 2 (two) 8.00 inch (203mm) hydraulic cylinders.
MAIN AIR SYSTEMS:
The screw compressor is located within the machinery house just forward of the hydraulic pump gearbox. The rotary screw compressor is an oil flooded, single stage twin screw type compressor which has a nominal rating of 3,000 cfm (84.9m3/min), @ 65 psi (74.7 m3/min) and a maximum operating pressure of 65 psi.
HYDRAULIC SYSTEM:
Hydraulic pressure for operation of the machine is provided by four separate pumps. These pumps are driven by the electric motor located in main machinery house, forward of the hydraulic filters and reservoir. The machine has 2 separate, though not completely independent hydraulic systems, the OPEN and CLOSED circuits. Both draw fluid from a common reservoir.
OPERATOR’S CAB:
The sound insulated operator’s cab of the machine provides a sealed, comfortable enclosure from which the operator can perform the tasks involved with the operation of the machine. The location and design of this compartment have been structured to provide the optimum viewing angles with immediate accessibility. The swivel mounted chair provides easy access to all required controls. The auxiliary control console is within reach to provide access to additional functions of the machine. The cab is provided with dual doorways to the main deck.
