Dear Operator,like driving a car, drilling bears hazards to you and your environment. Good training, discipline and well maintained equipment are the keys to safe operation. This instruction book is no replacement for a thorough training on the rig, but as a training aid and a reference book it shall help you to maintain a safe working environment and the operability of your rig.
Yours faithfullyAtlas Copco Rock Drills AB
General safety advice
Operating safety
Intended use:
The pneumatic drill rig ROC 203PC is solely designed for drilling holes in surface
working,
i.e. usually quarries, opencast mines and construction engineering.
Any use going beyond this shall be considered not to be intended use.
Not-intended use is e.g.:
- Lifting and transport of loads
- Lifting and transport of personnel
- Stabilization of other equipment
The manufacturer is not liable for damage incurred as a result; this shall be at the
owner’s risk. Proper use also includes observation of operating, servicing and
maintenance instructions stipulated by the manufacturer.
The ROC 203PC may only be operated, serviced and repaired by personnel familiar with
it and informed of the dangers.
Relevant accident prevention regulations as well as other generally recognized safety,
occupational medicine and traffic regulations must be observed.
The manufacturer is not liable for any damage caused by unauthorized alterations made
to the crawler drill.
Organizational measures:
1. The pneumatic drill rig ROC 203PC shall be operated only by personnel, which has
been given a practical training on the rig. Particular emphasis shall be laid on safety
precautions.
2. Keep this instruction book as well as the other instructions books listed in the chapter,
"Separate Instruction Books“ on the rig at any time.
5
3. As far as necessary or required by regulations use personal protective equipment.
4. In case of possibly safety relevant changes of the rig or its operational behavior
immediately shut down the rig and investigate the problem (seek advice from your Atlas Copco representative if necessary).
5. Keep the warning plates attached to the rig complete and legible.
6. Have the daily safety check carried out as described in this instruction and follow the maintenance measures as described in the service schedule.
7. Works to the hydraulic system shall be carried out only by personnel with particular skills and experience.
8. Any welding shall be carried out only by an authorised welder qualified acc. to EN 287 part 1 or equivalent.
9. Following repair, the rig shall be inspected and approved by the proper authorities before being put back into normal service.
10. Never carry out alterations or modifications to the rig, which might affect the operating safety, without full approval of the manufacturer.
11. The sound power level at the operator’s place are 126 dB(A).
Operation and maintenance:
1. Apart from this instruction book also follow the generally recognized safety and accident prevention regulations.
2. Prior to starting-up get familiar with the rig’s features, controls and their functions. This instruction as well as the others listed on page 3 will help you.
3. Make sure the required maintenance measures acc. to the service schedule have been carried out and carry out the ,,Daily checks“ prior to each shift. Never operate the rig when its safety is doubtful.
4. Always wear a hard hat, ear mufflers and well-fit clothes. Wear protective gloves when you handle drill rods, couplings can be hot. Wear a breathing mask during drilling (rock drill exhaust air contains oil spray).
5. Check the vicinity of the drill rig. During drilling and travelling there should be no unauthorized personnel around. At critical locations, however, like close to unsecured benches, a supervisor should be present. Care for sufficient sight. Check the travel path if necessary.
6. Prior to pressurizing put all levers and switches to NEUTRAL.
7. Never leave the rig unobserved during drilling.
8. Be careful when you handle hydraulic oils (avoid contact with skin and eyes).
9. Always shut down the rig and depressurize the air system before you carry out any disconnection work to the pneumatic or hydraulic system.
10. Be extremely careful searching leakages in the pneumatic or hydraulic system. Highly pressurized liquids (like hydraulic oil) or pressurized air could penetrate clothes and skin and cause heavy injuries or infections. In case of such accidents always look for a doctor immediately.
11. Dispose oils and filters environmentally.
12. Avoid the employment of cleaning agents containing solvents (e.g. carbon tetrachloride). There are alternatives available being much less dangerous to health and environment.
13. Spare parts shall at least comply with the standards as stipulated by the end manufacturer.
14. Operate the rig in daylight only.
This is guaranteed e.g. by the employment of genuine Atlas Copco parts.

Frequently encountered safety risks
1. During transportation and particularly during hoisting there is an increased hazard of overturning. During hoisting the Track oscillation shut-off valve must be in position BOTH CYLINDERS CLOSED.
2. The rig could tip over during tramming in extreme terrain. In order to avoid overturning during tramming:
- Keep Track oscillation shut-off valve in position BOTH CYLINDERS OPEN
- Lay down feed resp. to provide an optimum center of gravity
- Max. inclination in tramming direction: ± 20° solo machine (feed laid down)
- Max. lateral inclination: ± 20° solo machine (feed laid down)
- Operate the rig from the uphill side
3. The rig could tip during drilling in extreme positions. In order to avoid tipping during drilling:
- Keep Track oscillation shut-off valve in position BOTH CYLINDERS CLOSED
- Max. inclination in tramming direction: ± 20°
- Max. lateral inclination : ± 20°
- Operate the rig from the uphill side
4. When the drill string gets stuck never grip the drill steel nor apply a spanner or similar tool while the rotation motor is under pressure. The drill steel could suddenly break free and squeeze the arm resp. toss about or fling the tool all of which could lead to severe injury or death.
5. Before maintenance depressurize the rig.

Before each shift commences,
an extra and thorough safety check
shall be carried out, intended to
detect:
l cracks or fractures in materials or
at welded points.
l damage, which could cause
structural weakness or fracture,
l wear, with the risk of the same
consequences,
l loose junctions,
loose threaded unions.
If the crawler has been subjected to
abnormally high stress, then vital
load-bearing components may have
become damaged in the process.
From the safety aspects therefore, the
following check points are particularly
important (see illustration on opposite page):
1. Tow hook
2. Chain tensioner
3. Track frame attachment
4. Boom support
5. Boom
6. Boom head
7. Drill steel support
8. Feed gear (*)
9. Feed holder with attachment
10. Feed beam *
11. Rock drill and cradle *
12. Feed chain with attachments *

Recommended hydraulic oils and lubricants
Lubricating point Recommendation
Hydraulic oil tank l Use mineral-based hydraulic oils with good anti-wear, anti-rust, anti-oxidation and foam inhibitingproperties and with good air and water separation characteristics. Choose an oil with viscositygrade (VG) and viscosity index (VI) in accordance with the table below. An oil with a high viscosityindex is less sensitive to the effects of temperature:
