Atlas Copco is not liable for any damage caused by unauthorised modification to the machine and its equipment. Atlas Copco is not liable for damage caused by inappropriate use. Overloading the machine can result in damage to the structure which is not noticed during normal usage. Such damage is not covered by the warranty. Damage that occurs as a result of inadequate maintenance, substandard repairs, or damage to equipment that is attributable to older unrepaired damage, is not covered by the warranty.
SmartROC T45-11 2 About Maintenance Management 2 About Maintenance Management 2.1 Maintenance Planning and Counters Maintenance is organised at scheduled intervals. Scheduled intervals supplement each other. Longer interval contains maintenance tasks supplementary to tasks from shorter interval. Maintenance scheduling should be applied periodically to unit/ function's shortest interval (whichever comes first during operation). Operational maintenance is planned based on the following counters: Hour meters for the rock operation system Hour meter for the engine or motor Calendar based maintenance applies to all rubber details, lubricants that risks break ing up during standstills, pressure vessels. Corrosion and such where age, substance regression and environmental exposure are vital to maintenance factors. 2.2 Maintenance Records Correct records enable maintenance personnel to identify and evaluate problems and/or high cost areas. All maintenance procedures should be checked off as the inspection or procedure is completed. Quantities of refilled lubricants and fluids, and pressure and flow readings, should be recorded. Any faults or deviations should be recorded irrespective of whether they have been rectified or are waiting for rectification.

SmartROC T45-11 5 Feeder Unit 5.17.1 Checking Cable for Wire Breaks Wire breaks occur after a certain operating time depending on operating conditions and subsequently occur more frequently. The number of wire breaks in relation to the operating time should be determined and documented. This can then be used to estimate the future increase in wire breaks and the foreseeable time point for scrapping. On 6 and 8strand ca bles, wire breaks are primarily superficial. Broken wires at cable ends indicate that they have been heavily loaded and can be caused by faulty end mountings. Shorten the cable and reattach it. Check that the length of the remaining cable sufficient. If there are concentrations of cable breaks, the cable must be scrapped. If such con centrations occur within a length less than 60 cm or on an individual strand, the cable must be scrapped. even if the number of wire breaks is less than the maximum speci fied in the table. Number of load Number of visible wire breaks that require scrapping bearing wires in Machine groups M1 and M2 the outer strand. Filler wire is not Cross Lay Equal Lay considered load Over a length of cable diameter (d) bearing. 21220 221240 In cables with several layers of strands, only the outer, visible layer is considered. In cables with steel cores, the core is regarded as an inner strand and is not included. In the event of a wire break, two ends can be visible. 5.17.2 Checking Cable for Strand Breaks If there are strand breaks, the cable must be scrapped. 5.17.3 Checking Cable for Surface Wear Inner surface wear is caused by friction between the wires and the strands. Outer surface wear is caused by friction between the cable drums (rolls) and the cable un der pressure (acceleration and braking). Outer surface wear is visible through the forma tion of reflected images on the outer wires.
SmartROC T45-11 5 Feeder Unit Inner corrosion is more difficult to detect. Inner corrosion is characterised by the following: Absence of gap between the strands in the outer layer of the cable, often in combina tion with wire breaks in the strands. The cable diameter varies. The parts of the cable that are bent over discs usually have a decreased diameter. At any sign of corrosion, the cable should be checked by an authorised person. If inner corrosion is detected, the cable must be scrapped. 5.17.5 Checking Cable for Decreased Diameter Decrease in cable (steel wire) diameter through material fatigue in the cable can have the causes: Inner surface wear and surface wear nicks Inner surface wear through friction between the strands and wires in the cable Fatigue of plastic core Break in steel core Break in inner layer in multistrand cable If the cable's diameter decreases more than 10% in relation to the nominal diameter of the cable, it must be scrapped. It should be scrapped even if no wire breaks have been de tected. 5.17.6 Checking Cable for Reduced Elasticity Under certain conditions, the cable loses its elasticity. Reduced elasticity is difficult to de tect. If in doubt, consult a specialist. If the cable has lost elasticity, the following character istics usually appear: Decrease in cable diameter Extension of the cable No gap between individual wires and between the strands. This is caused by its com ponents being pressed together. Fine, brown dust inside the strands. Even if there are no visible wire breaks, the cable is noticeably stiffer. The cable's diameter decreases more quickly than during normal wear of the individual cable strands. Reduced elasticity can lead to sudden cable breaks during heavy loads. The cable should be scrapped. 5.17.7 Checking Cable for Heat Exposure The effects of heat can be established through annealing colour. Cables exposed to ex treme heat must be scrapped.

SmartROC T45-11 7 Hydraulic System 7 Hydraulic System 7.1 About Working on Hydraulic Components The hydraulic system is sensitive to contamination. The environment where the machine is normally used is generally an unsuitable place for repairing hydraulic components. Avoid repairing hydraulic systems outside workshops. Observe the following points to minimize interruptions in operation due to contaminated hy draulic oil: Keep the machine clean. Use a degreasing additive for washing. Before opening any hydraulic connection, clean the area round it. Use clean tools and work with clean hands. Always plug hydraulic connections immediately after they have been detached. Use clean protective plugs. Hydraulic components, for example like hoses, valves, engines, must always be stored with suitable protective plugs fitted. Spare parts for hydraulic components must always be kept in sealed plastic bags. Change filter cartridges when filters indicate clogging. 7.2 About Hydraulic Workshops Workshops used for the repair of hydraulic components must include: A clean environment to avoid dust and particles Suitable washing equipment which is required for repairing the components Suitable tools for work on hydraulic systems Adequate ventilation system 7.3 About Replacing Hydraulic Hoses Load, vibration and other mechanical stresses put high demands on hydraulic hoses. When replacing, check that replacement hoses are made: With correct crimped couplings With correct quality class With correct dimensions All pressurised components should be purchased from Atlas Copco. Grades and dimen sions of hoses are specified in the spare parts catalogue. Also make sure that hose cou plings are clean, not damaged and properly tightened. 7.4 Check Hoses and Couplings Inspect all hydraulic hoses and connections thoroughly with respect to cracking and swelling that indicates an external or internal leak. Inspect hose location and clips.
SmartROC T45-11 7 Hydraulic System Inspect hydraulic couplings with respect to leaks, indentations and adapters. Cou plings should be fastened securely if they have screw flanges. If there are any signs of connection leaks, change sealings or the complete coupling. Inspect that all hose attachments and clamps are intact. Inspect all pressed couplings for signs of cracks or damage to compression sleeves. Replace defective hoses with new ones. 7.5 Hydraulic Filters 7.5.1 Return Oil Filter The return oil filter cleans the oil before it returns to the tank. The filter cartridges should be replaced according to the maintenance schedule. If the return filter pressure gauge on the operator display indicates a clogged filter, all return oil filters must be replaced immedi ately. Symbol for Clogged Filter 7.5.2 Check Breather Filter The purpose of the breather filter is to equalise the pressure differences in the tank that would otherwise arise when the level in the tank changes.

SmartROC T45-11 8 Electrical System 8 Electrical System 8.1 Charging the Battery WARNING Risk of Fire and Explosion May cause serious personal injury and damage to property. Explosive gas is formed in the battery during charging. Avoid naked flames and sparks. Ensure good ventilation. Always disconnect the negative terminal first, and connect it last. The battery is normally charged by the alternator. If the battery is fully discharged for some reason, it must be recharged using a battery charger. Cell plugs should be unscrewed and left in the holes during charging. Batteries contains corrosive fluid. Always turn off the charge current before disconnecting the clips. If the density has not risen noticeably de spite a number of hours of charging, the battery is probable expended. Rapid charging, when carried out correctly, will not damage the battery. Rapid charging should not be un dertaken too often and is not recommended for old batteries. Repeated discharging for long periods will impair the service life of the battery. Avoid, for example, leaving the lights on while the engine is stationary. Discharging with high current is not normally harmful. Since the 24V electrical system is powered by two 12V batteries connected in series, ob serve: The batteries must have the same capacity (Ah). The batteries must be the same age. This is because the charging current required to bring a battery up to a certain voltage changes with age. The batteries must not be loaded unevenly. Series coupling maintains the same capacity but increases the voltage. For example, when 2 x 12V 60Ah batteries are connected in series, the voltage will be 24V but the capacity remains at 60Ah. Use a 24V charger when charging both batteries connected. Use a 12V charger when charging each battery individually. Observe the voltage before connecting a battery charger.

If the compressor is noisy at a certain speed, and the noise disappears when the speed increases or decreases, there is probably nothing wrong with the compressor itself. The difference between the pressure on the suction side and the pressure side also affects the level of noise. A compressor with low suction makes more noise than a compressor with high suction. Likewise, a compressor with highpres sure makes more noise because it puts more load on bearings and other components. Abnormal noise Check the multiVbelt to the compressor is thor oughly tightened and that the compressor retain ing bolts are tightened Check the system is filled sufficiently and not over filled Check the expansion valve is in working order Check the airflow across the evaporator is suffi cient Check the condenser is clean and the airflow is sufficient...

SmartROC T45-11 21 Start-Up 21 StartUp 21.1 About Special StartUp Special startup is performed when commissioning the machine for the first time. An Atlas Copco representative will perform a special startup procedure. Special startup of drilling machine and associated equipment is also performed in the fol lowing cases: After a long standstill (one month or more). After major change of components or repairs. Maintenance personnel or an Atlas Copco representative shall take part when starting up or during a test startup after maintenance. 21.2 Performing Special StartUp WARNING Risk of Serious Personal Injury Stay out of the machine's operating zone. Followup on any installation or maintenance work that has been carried out and com ponents that have been changed. These will require special attention during special startup. The pumps must be primed before start if the circuits have been drained. At the startup moment, the operator and any personnel present should stay out of the machine's operating zone (4 m allround). Maintenance technicians can later enter this zone. Operators should remain with the operating console or remote panel in the immediate vicinity of the emergency stop. Check that the fire extinguisher and fire fighting system are fully functional. Pay extra attention to any electrical work that has been carried out. Listen for any noise that indicates defects. Stop the machine immediately if this should occur. Look for any signs of overheating or fire. After a special startup, the operator and maintenance technician must carry out re maining checks as instructed. 21.3 Flushing of Hoses and Pipes After first startup and after long standstill, flushing of the external hoses and pipes are rec ommended.
SmartROC T45-11 21 Start-Up Disconnect the hoses from the hydraulic cylinders and join together the hose piston and piston rod end. Flush each circuit for approximately 10 minutes. Use a high flow at low pressure. Check the hydraulic oil level on the level gauge before flushing the next circuit. After flushing all the circuits, switch off and connect the hoses to the cylinders. Place a vessel by the hydraulic tank with a hose from the filling/draining system in the vessel. Remove the protective hose plug. Top up the oil level in the hydraulic tank after bleeding air from the system. 21.4 About Testing Pressure Release Valves The test procedure involves removing each valve and loading it with pressure in a test bench to ensure its setting and function. This requires special test equipment and a sound knowledge of the hydraulic system. Contact Atlas Copco for pressure testing relief valves used in critical safety functions.
