The objective of these maintenance instructions is to detect and rectify faults at an early stage so that breakdowns, costly secondary damage and accidents can be pre-vented Regular maintenance is a precondition for planning necessary interruptions in operation such as reconditioning and repairs This allows maintenance to be carried out when most suitable with regard to production instead of causing complete break-down

Hydraulic systems

General

Hydraulic systems are sensitive to impurities and pollutants The environment in which rock drilling equipment usually works is generally unsuitable as a place for repairing hydraulic components Work on the hydraulic system at the worksite should therefore be limited to what is absolutely essential The components should then be repaired in a suitable environment, see the section Hydraulic workshops

Observe the following points to avoid breakdowns and interruptions in operation due

to fouled hydraulic oil:

• Keep the rig clean Hose it down at regular intervals, preferably with a grease vent as an additive

sol-• Before opening any 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 like hoses, valves, motors, etc must always be stored with suitable protective plugs fitted in place

• Spare parts for hydraulic components must always be kept in sealed plastic bags

• Change filter cartridges as soon as the filters indicate clogging

Repairing hydraulic components

Repairing and/or reconditioning hydraulic components should be carried out by expert personnel and in a suitable place The following alternatives are possible:

• Suitable premises for hydraulic repairs to be arranged at the workplace Repairs to

be carried out by your own specially trained personnel, the manufacturer's cians or Atlas Copco personnel

techni-• Components to be sent to the manufacturer's local agent for repair

• Component repairs are carried out by Atlas Copco Repair instructions are ble for the most important and most complicated hydraulic components

availa-Hydraulic workshops

Workshops used for the repair of hydraulic components must:

• be separate from activities which generate dust and particles, such as welding, grinding, the transportation of vehicles, etc.;

• have their own suitable washing equipment which is required for repairing the components;

• have the necessary tools, both standard and special, and that are only used in the hydraulic workshop

• have a ventilation system that does not admit dust into the premises

• have well-trained mechanics

Replacement of hydraulic hoses

A high percussion pressure, vibration and other mechanical interference puts high demands on the hydraulic hoses

When replacing hydraulic hoses, check that they are replaced with hydraulic hoses:

• with the correct crimped couplings

• of the correct quality class

• with the correct dimension

All hydraulic pressure hoses have crimped couplings and should therefore be chased ready-made directly from Atlas Copco Quality classes and hose dimensions are specified in the spare parts catalogue for the relevant rig Make also sure that hose connections are clean, in good condition and well tightened

pur-Welding

Note

It is important to consult Atlas Copco for approval of welding and choice of trodes.

elec-The following must be observed when welding:

• Turn off the supply of current to the unit

• Disconnect the cables from the generator and battery

• Grind off rust and paint from the area that is to be welded and carefully prepare the joint

• Weld in a dry area

weld-• Always protect hoses, cables and electric components.

• Grind off spatter after welding If possible, also grind the surface of the weld smooth and treat it with anti-corrosion paint

Electrode recommendations

Use only intact and clean electrodes that have been stored in a dry place The ally recommended type of electrode is ESAB OK 48.00, ESAB OK 48.30 or the equivalent in accordance with the standard below:

gener-Table: Electrode recommendations

The use of MIG welding equipment is perfectly acceptable The generally mended type of electrode is ESAB-OK Autorod 12.51 or the equivalent in accord-ance with the standard below:

recom-Table: MIG electrodes

If in any doubt, contact Atlas Copco for advice

Tightening torque in bolted joints.

All joints are tightened to the torque specified in Atlas Copco Standard 4369:01 K, unless otherwise explicitly specified In such a case, it is specified in the maintenance instructions of the component in question

Table: Atlas Copco Standard 4369:01 K.

Markings and plates

Signs are placed on the larger carrier components Always quote the type designation and serial number when ordering spares or enquiring about the carrier The type des-ignation and serial number are specified on a separate document, DRI (Drill Rig Identification) Spares can always be ordered from Atlas Copco

class

Torque in Nm.

Dismantling and assembly

Before transport in shafts or the like it may be necessary to remove the drilling rig in larger or smaller parts Observe the following when dismantling, lifting and refitting:

• Before dismantling, hose the entire rig clean with water and/or detergent ing a grease solvent

contain-• Observe the strictest cleanliness when dismantling hydraulic, compressed air and water flushing hoses Immediately plug all hoses, nipples and hydraulic oil pipes,

or seal and protect them from dirt in some other suitable way

• Mark hoses, pipes and other connections, where this has not already been done, to make reassembly easier and prevent mix-ups

• Use properly secured lifting tackle of generous dimensions

• Can cause personal injury.

• Always lift at the centre of gravity.

• Use only straps that are whole and intended for the load in question.

• Fasten straps to lifting eyes when present.

Starting with an auxiliary battery

For this reason, proceed as follows:

1 Check that the auxiliary starting batteries (1) have the same voltage as the ies on the chassis

batter-Figure: Starting assistance

2 First connect the positive terminal of the auxiliary battery to the positive terminal

of the chassis battery (2)

3 Then connect the negative terminal of the auxiliary battery (1) to earth on the chassis (not to the chassis battery's negative terminal)

4 Once the engine has started, first remove the starter cable between the chassis and the negative terminal on the auxiliary battery (1)

5 Then remove the cable between the positive terminals of the batteries

Maximum temperature in hydraulic oil reservoir, °C

Viscosity grade (VG) (ISO 3448)

Viscosity index VI

Lubrication oil

Rock drill (ECL lubrication system)

Use a mineral-based pneumatic tool oil with additives against wear, ice formation and oil mist The viscosity grade should be suitable for the ambient temperature as follows

Table: Recommended viscosity grades

Diesel engine

Engine oils have different properties and are classified in different grades The API (American Petroleum Institute) or ACEA (Association des Constructeurs Européens d’Automobiles) classification systems are normally used

The following grades are permitted for API oils

Table: Recommended viscosity grades

Ambient temperature °C Viscosity grade (ISO 3448)

Hydraulic transmission

Different types of fluid can be used in the hydraulic transmission

• Dexron IID oil or Dexron IID equivalents

Dexron IID and Dexron IID equivalents must not be blended with the other oils.

The oils below are miscible with each other

• Transmission fluids complying with CAT TO-4 or Allison C-4

• Universal oils complying with API CD or Allison C-4

• Multigrade engine oils complying with API CD or Allison C-4

Table: Recommended viscosity grades

Wheel axle centre and hub reduction gears

Use transmission oil with grade classification API GL-5 LSA and viscosity grade SAE 85W-90

Compressor

Use compressor oil or hydraulic oil It must be a mineral oil of high quality with tives to inhibit oxidation, foaming and wear The viscosity grade must suit the ambi-ent temperature and fulfil ISO 3448 as follows

At low temperatures, paraffin deposits in the diesel can cause blockages resulting in disturbances in the fuel system A special winter diesel should therefore be used with ambient temperatures below 0 °C.

Coolants

Diesel engine cooling system

It is important that the water used in the diesel engine cooling system is the right quality The values in the following table must not be exceeded

Table: Recommended water quality

An anti-freeze additive will protect against corrosion, cavitation and freezing Use anti-freeze that is free from amines, nitrites and phosphates Anti-freeze concentra-tion in the coolant must be kept between the following minimum and maximum lim-its

• Min = 35% by volume

• Max = 45% by volume

The following tables show the freezing point for different mixtures of anti-freeze and types of engine
