General

We recommend that records be kept on service and wearing part replacements. Regular maintenance at correct intervals increase reliability, economy and safety of the equipment. Even maintenance work can be dangerous, unless caution is observed. Everybody involved in maintenance work should understand the possible hazards and use safe working methods. Before starting any maintenance or repair work, read the manufacturer’s instructions and follow them.

The person responsible for maintenance and repairs should be clearly defined. • Do not do any work that you are not authorized to do. • Inform the users of the equipment of the start of special or maintenance work. • Reserve a sufficient safety area around the rig for maintenance work. • If the equipment or a part of it has been stopped for maintenance or repair, make sure that it cannot be started accidentally.

Turn the main switch off Remove the ignition key Put a warning sign on the main switch. The sign can be removed only by a person who is fully aware of the situation and who can be sure that the sign can be removed without causing danger. • Clean and wash the equipment regularly and always before maintenance or repair work. • Before starting to clean the equipment with water, high-pressure washer, steam or other cleaning methods, protect all such openings and other points that can cause danger or become broken. Especially electric motors, switchgear cabinets and electric boxes need to be protected. • If required, suitable and safe ladders or working platforms for repair and maintenance work. • Do not use parts of the equipment as steps. If maintenance work must be done high up, or in an otherwise dangerous place or position, use necessary safety devices to prevent falling. • All platforms, steps, grips, rails, ladder and other similar parts must be kept clean of oil, dirt, snow and ice to prevent accidents caused by slipping. • Always use proper working equipment. • if you are doing maintenance or repair work under the vehicle, engage safety and parking brake. Make also sure that accidental starting or moving is prevented. • When changing tyres or wheels, make sure that the equipment is in balance and properly supported. Refer to the specifications for maximum tyre pressure. Do not exceed maximum tyre pressure. • Do not stand in front of the wheel when the tyre is being inflated. • Inflating tyres on demounted wheels: DANGER of serious injury! If split rims are used, tyres must be inflated in special safety cages. Never stand in front of the wheel when the tyre is being inflated. • Pay special attention to the exhaust piping and the exhaust gas cleaning system. Ensure sufficient ventilation.



13 (48)


• Overheating indicates a fault. Stop the engine and repair the fault before more serious damage is caused. Make sure that the engine radiator is not covered and that is not clogged. • When checking engine coolant level, stop the engine and allow it and the radiator to cool down for a while. If an overheating engine must be stopped, allow the radiator to cool down for a while before checking coolant level. If there is no time for that, use thick gloves and protective clothing when opening the radiator filling cap. Stand to the side, turn your face away then open the cap a little. Wait until the pressure is released and coolant stops running out, then open the cap slowly. • When replacing heavy parts or units, fasten them properly to the lifting device and make sure that the motion does not cause any danger. Use only suitable and technically faultless lifting devices and lower the load on a surface that can carry the weight.

2.6

Refilling fuel

The following precautions must be observed when replenishing fuel: • Do not fill fuel tank when the engine is running. • Take care not to spill fuel on hot surfaces. • Fuel filling should be done in a well ventilated space. • Smoking, open flame and sparks are dangerous when the fuel tank is being filled. • Wipe off spilled fuel before starting the engine. • keep the fuel replenishing pipe in contact with the fuel tank or arrange earthing to prevent sparking caused by static electricity. • Cabin heater must be switch off.

2.7

Pneumatic circuit maintenance

The pneumatic circuit must be completely pressureless before any repairs are made. • Make sure that the pneumatic system is completely pressureless before starting maintenance or repair work on the compressor. • The system pressure must not be adjusted higher than specified by the manufacturer. Increasing the pressure does not increase the performances of the equipment.

2.8

Rock drill pressure accumulators maintenance The pressure accumulators of the rock drill are pressurized with nitrogen gas N2. Before removing the accumulators, release the pressure by opening the filling valve. Do not pressurize the accumulators over the specified filling pressure. Follow the instructions for pressure accumulator maintenance and repair.



14 (48)


2.9

Hydraulics maintenance

Maintenance, repair and installation of hydraulic equipment is only allowed to experienced hydraulic experts. • Do not attempt any such repairs that you do not dully understand. • Never do any repair work on the hydraulic circuit if the system is pressurized. • Do not use the drilling equipment if the system has a hose leakage. • Do not tighten or repair a leaking hose connection before stopping the engine and all power packs. • Do not try to locate a leak from a hose or a connection by feeling with your hand. The high pressure oil spray from the leak can penetrate the skin and cause a serious condition. A highpressure oil spray can also start a fire. • Avoid direct skin contact with oil. Prevent oil from getting into your eyes; use eye protection. • Do not work under a device or component that is held up only by the hydraulic cylinders or motors. Use separate supports in conjunction with maintenance and repair. • Do not remove boom cylinders or their non-return valves before the boom, the feed and the rock drill are properly supported. • Pipe connections, hose lengths and hose types must correspond with the specifications. When replacing or repairing hoses, use original TAMROCK spare parts or hoses and fittings recommended by the manufacturer. Ensure that the pressure ratings of the hoses and connecting fittings correspond with the working pressures. • Any alterations require a written authorization from the manufacturer.



15 (48)


2.10

Electric system maintenance

• Work on electric equipment or materials is only allowed to qualified electricians or their assistants under their supervision and control, observing the electrotechnical regulations. • The local electrotechnical and electric safety regulations must always be observed. • Always use only original electric components. • If disturbances in electric supply occur, stop the rig or device at once. • Voltage must be cut off from the parts of the equipment or device that are to be checked, serviced or repaired, if the regulations so require. Check that the disconnected parts are dead and then lock the main switch or arrange a work earthing if necessary. • Check the operation of earth fault protection every week. This is done by pressing the test button. If no cut-off takes place, the protective device must be repaired before starting any devices connected to it. • When handling high-voltage components, remember that capacitors may have an electric charge, although voltage is cut off. Short the capacitors with an earthing rod. • Before making any changes on the electric devices, TAMROCK’s electric engineering department must be consulted and a written authorization received, to make sure that the proper operation of the device does not change.

Working on live components • If the component must be live, a fellow worker must be standing by to the cut off voltage at the emergency or main switch in an emergency situation. Follow the electric safety regulations. • Use a red-and-white safety chain and an warning signs to encircle the working area. • Use only insulated tools • Observe special caution.



16 (48)


2.11

Battery maintenance

Always wear eye protection, protective overalls and protective gloves when servicing batteries. • Always disconnect the negative (-) pole first and then the positive (+) pole. Always connect the positive pole (+) first and then the negative pole (-). • To prevent sparking when connecting a battery charger, pull the charger supply cord or switch the charger off before connecting the charging wires to the battery terminals. Open the battery cell caps slightly during charging to allow the generating gases to escape. • The acid in the battery burns the skin, eats holes in clothing and can cause blindness if it gets in the eyes. If you get battery acid on your skin, flush the spot at once with plenty of water. Use sodium bicarbonate to neutralize the acid if it gets in the eyes. Flush the eyes with plenty of water and call a doctor. • When servicing batteries, remember that lead-acid batteries generate (during charging and discharging) oxygen and hydrogen which form a highly explosive mixture. A spark or an open flame can cause an explosion. If necessary, ventilate the battery compartment properly before disconnecting or connecting the cables. • To prevent explosion, the electrolyte liquid level must be kept correct and checked regularly. Add distilled water, if required, before starting, never immediately after use. With the electrolyte level high enough, the cells have less space for gases. • Use a flashlight when checking electrolyte levels, never an open flame. • The battery terminals should never be shorted. The sparks can cause the battery to explode. • Do not test electric devices by making the contact directly to the battery terminals.

2.12

Welding

Before starting to weld, determine the material to be welded, the welding method and fillers. Contact TAMROCK service if necessary. • Do not repair steering equipment by welding. • Welding must be left to qualified personnel. • Disconnect both cables from the battery before starting to weld. The welding voltage can damage electric devices. • Use a protective mask when welding. • Arrange adequate ventilation. • Arrange protection against fire.

AXERA D06 IMPORTANCE OF PERIODIC MAINTENANCE

3

IMPORTANCE OF PERIODIC MAINTENANCE

Properly done and correctly timed, periodic maintenance guarantees the reliability of the equipment. The purpose of periodic maintenance is to have the rig checked regularly and thus to ensure a high level of serviceability. This will prevent costly damages and downtime which cuts productivity. Neglected maintenance means extra cost! It is important to do the daily service routine carefully. Any possible fault must be repaired at once or reported to the person in charge. The daily routines include lubricating, checking and adjusting. Every new operator must be able to manage the daily service routines. These periodic maintenance instructions distribute the maintenance intervals according to the Diesel engine’s running hours and the rock drill’s percussion hours.

3.1

General notes on maintenance work 1; Always shut off the rig before maintenance work. Prevent accidental starting by turning the main switch off or remove the ignition key. 2. Make sure that the rig will not move. 3. Clean the rig before maintenance. 4. Make sure that:

• tools • spare parts • materials (oil, lubricants etc) needed are ready at hand.

5. Carefully clean around the filling caps before refuelling or topping up of oils. 6. Check the cleanliness of the oil used always when changing oil or replacing the filters. A large amount of impurities (e.g. clogged filter) may be a sign of a fault that must be repaired at once before it will cause more serious damage. 7. Beware of hot surfaces and hot oils. Dispose of used oil and filters according to the local regulations. 8. All guards and covers must be installed back after the maintenance work.

WATER CIRCUIT EVERY WEEK OR 50H

WATER SUPPLY

FILTER RÉDUCER

Clean the filter strainer.

Checking of the supplied pressure: - stop all power-packs. - Check the water supplied pressure. It must be above 2 bar and 5 bar as a maximum. If the supplied pressure is higher than 5 bar, adjust the reducer. Checking of outlet pressure - make sure that all controls are in neutral position. Start the main power pack(s). - make sure that the rock drill (both on two boom machines) is in drilling condition: the flushing head in good working condition, a rod and a bit installed. - operate the water control valve (both on 2 boom machine). - read the water pressure. It must never be below 10 bar

IF THE OUTLET PRESSURE IS BELOW 10 BAr: • Make sure that the mine supply pressure is 2 bar minimum • Ensure that the water supply hose is of a correct size and not clogged. • Clean the filter strainer. • Make sure that the cooler is not clogged by mineral deposit (both cooler on two boom machines). Remove deposit if needed. • After checking all above points if the pressure is not correct the pump should be repaired..

NOTE: the outlet relief valve allows the adjustment of the maximum pressure to protect the flushing head seals. The outlet pressure must be below 18 bar. According to the drilling conditions (size of the rod and the bit), the pressure can reach the setting of the outlet relief valve. Water is then released to the ground. To avoid water leakage it is possible to reduce the supplied pressure. As the pump works as an amplifier by dropping the supplied pressure the outlet pressure drops. INLET PRES. + PUMP PRES. = OUTLET PRESSURE

EVERY WEEK OR 50H ADJUSTING SCREW

LOCK NUT

Start the compressor, check the pressure. The pressure should not exceed 2 bar when installing a gauge at the inlet port of the rock drill. According to the length of the air line the pressure at the compressor or at the oiler may be higher. Adjust the compressor pressure to get 2 bar at the rock drill inlet port. If a pressure reducer is installed on the machine, it is then possible to adjust the compressor pressure to 7 bar.

EVERY 600H OR 6 MONTH Replace both air filter elements. Replace the oil separator element. Refer to the compressor maintenance booklet.
