• Section 2 – Operation: Preliminary procedures, travelling and tramming controls, towing procedures, dog brake operation, hydraulic control of boom and drill guide, conversion between horizontal and vertical drilling, DTH drilling preparation, drill and feed motor control valves, drilling procedure, adding and removing drill rods, precautions during drilling, hole cleaning.
• Section 3 – Warranty: Warranty terms, coverage periods (360 days/2400 hours and 180 days/1200 hours), repair kits for G35DTH and G35TH, end-user responsibilities.
• Section 4 – Maintenance: Track chain tension adjustment, feed chain tension adjustment, rotary head mounting plate tightening, drill guide installation, airline lubrication, hydraulic system inspection, lubrication chart, greasing points, feed motor pressure regulator adjustment, feed motor removal/disassembly/reassembly, hydraulic pump air motor service, gear pump service instructions, DTH setup and troubleshooting, bit installation, makeup torque, DTH disassembly and assembly, drill lubrication, DTH hammer specifications and troubleshooting, pneumatic drifter parts list and maintenance, troubleshooting.
• Section 5 – Parts List: Illustrated parts lists for main frame assembly, track frame assembly, track idler assembly, track roller assembly, track chain assembly, traction drive unit, gearbox drive unit, gearbox traction, air motor traction, dog brake assembly, boom assembly, cylinders (boom lift, boom swing, guide dump & swing, guide extension), angle indicator, drill guide assembly, centraliser, feed assembly, air motor feed, rotary head assembly, gearbox rotary head, hydraulic pump assembly, hydraulic pump, air line lubricator, and seal kits.

This G35DTH G35TH crawler drill manual is not a generic rock drilling guide. It is written specifically for the Global Mining Equipment G35 series crawler rig and includes the exact maintenance intervals, torque specifications, and adjustment values that GME specifies for these machines. The preventive maintenance schedules alone — covering 600-hour, 1200-hour, and 2400-hour service intervals — give owners a clear roadmap for keeping the rig in production and avoiding premature component failure.

Detailed Operation and Drilling Guidance

The operation section walks through every control on the machine. You will find the tramming and towing control lever functions, including how to make right and left turns using independent track control, and the correct clutch disengagement procedure before towing. The dog brake operation is explained with step-by-step engagement instructions for locking the crawler on sloped ground. The hydraulic control valve is detailed with the five lever functions: drill guide extension, drill guide swing, drill guide dump, boom swing, and boom lift.

For DTH drilling, the manual covers choke sizing and bailing velocity requirements, valve and choke selection, bit installation with tapered retaining rings, makeup torque and backhead closure, and the complete disassembly and assembly sequence for the GM4 DTH hammer. Lubrication requirements are specified with oil quantity per 100 scfm of air, and the difference between plunger and venturi lubricators is explained.

Maintenance and Service Procedures

The maintenance section provides the practical procedures a technician needs. Track chain tension is adjusted to 15–20 mm slack, feed chain tension to 10–20 mm slack, and the manual explains how to tighten the rotary head mounting plates to prevent vibration-related loosening. Airline lubrication is covered with the 8-litre lubricator adjustment procedure and a test to confirm oil is reaching the drill exhaust. The hydraulic system section includes cylinder air removal, hose and piping inspection, and oil level checks.

The feed motor chapter provides complete removal, disassembly, inspection, reassembly, and installation instructions with torque values for the gear end and motor end. The hydraulic pump air motor service instructions cover reassembly of the rotor, vanes, cylinder, and heads. The gear pump service chapter explains dismantling, inspection of bushes and gears, renewal of the drive shaft oil seal, and direction of rotation identification.

Parts Identification for Repairs

The parts list section is a full illustrated breakdown of the G35DTH and G35TH. Each assembly is shown in an exploded view with part numbers, descriptions, and quantities. This is particularly useful for ordering aftermarket parts — the manual includes the parts ordering instructions that require the model number, serial number, order number, part name, part number, and quantity. Assemblies covered include the main frame, track frame, track idler, track roller, track chain, traction drive unit, gearbox drive unit, gearbox traction, air motor traction, dog brake, boom, all hydraulic cylinders, drill guide, centraliser, feed assembly, air motor feed, rotary head, gearbox rotary head, hydraulic pump assembly, and air line lubricator.

Pneumatic Drifter Coverage

For G35TH owners using the pneumatic drifter, the manual includes a dedicated section with the G120F drifter specifications (69 kg weight, 780 mm length, 120 mm piston diameter, 38 mm chuck, 7.2 kW maximum impact power, 33 Hz impact frequency, 0–210 RPM rotation speed, 167 l/s air consumption), a complete parts list with part numbers, the 6-month service kit contents, and detailed maintenance instructions including side bolt tightening torque, lubrication recommendations, and troubleshooting for issues such as reduced output, rapid rifle nut wear, rotation failure, and abnormal heating.

DTH Hammer Troubleshooting

The DTH troubleshooting charts cover common operational problems: rough-erratic operation, low penetration with high pressure, low penetration with low pressure, drill running off bottom, component failures, and breaking exhaust tubes. Each problem is linked to probable causes and remedies, from checking chuck length and rotation speed to inspecting valve lift and piston wear. This section alone can save hours of diagnostic time when the hammer is not performing as expected.

This GME G35DTH G35TH Crawler Drill User Manual gives you the complete factory documentation for operating, maintaining, and repairing the Global Mining Equipment crawler drill. It covers the DTH setup, the drifter maintenance, the hydraulic and pneumatic systems, and the full illustrated parts breakdown. With instant PDF delivery, you can have the manual on your phone, tablet, or laptop at the drill site, or print the pages you need for the workshop. No shipping, no waiting — just the complete manual for the G35DTH and G35TH crawler drill.
