Instruction Manual

14 All doors shall be shut during operation so as not to disturb the cooling

air flow inside the bodywork and/or render the silencing less effective.
A door should be kept open for a short period only e.g. for inspection or
adjustment.

15 Periodically carry out maintenance works according to the maintenance

schedule.

16 Stationary housing guards are provided on all rotating or reciprocating

parts not otherwise protected and which may be hazardous to personnel.
Machinery shall never be put into operation, when such guards have
been removed, before the guards are securely reinstalled.

17 Noise, even at reasonable levels, can cause irritation and disturbance

which, over a long period of time, may cause severe injuries to the
nervous system of human beings.
When the sound pressure level, at any point where personnel normally
has to attend, is:

- below 70 dB(A):

no action needs to be taken,

- above 70 dB(A):

noise-protective devices should be provided for people continuously
being present in the room,

- below 85 dB(A):

no action needs to be taken for occasional visitors staying a limited
time only,

- above 85 dB(A):

room to be classified as a noise-hazardous area and an obvious
warning shall be placed permanently at each entrance to alert people
entering the room, for even relatively short times, about the need to
wear ear protectors,

- above 95 dB(A):

the warning(s) at the entrance(s) shall be completed with the
recommendation that also occasional visitors shall wear ear
protectors,

- above 105 dB(A):

special ear protectors that are adequate for this noise level and the
spectral composition of the noise shall be provided and a special
warning to that effect shall be placed at each entrance.

18 Insulation or safety guards of parts the temperature of which can be in

excess of 80 °C (175 °F) and which may be accidentally touched by
personnel shall not be removed before the parts have cooled to room
temperature.

19 Never operate the unit in surroundings where there is a possibility of

taking in flammable or toxic fumes.

20 If the working process produces fumes, dust or vibration hazards, etc.,

take the necessary steps to eliminate the risk of personnel injury.

21 When using compressed air or inert gas to clean down equipment, do so

with caution and use the appropriate protection, at least safety glasses,
for the operator as well as for any bystander. Do not apply compressed
air or inert gas to your skin or direct an air or gas stream at people.
Never use it to clean dirt from your clothes.

22 When washing parts in or with a cleaning solvent, provide the required

ventilation and use appropriate protection such as a breathing filter,
safety glasses, rubber apron and gloves, etc.

23 Safety shoes should be compulsory in any workshop and if there is a

risk, however small, of falling objects, wearing of a safety helmet should
be included.

24 If there is a risk of inhaling hazardous gases, fumes or dust, the

respiratory organs must be protected and depending on the nature of the
hazard, so must the eyes and skin.

25 Remember that where there is visible dust, the finer, invisible particles

will almost certainly be present too; but the fact that no dust can be seen
is not a reliable indication that dangerous, invisible dust is not present in
the air.

26 Never operate the unit at pressures or speeds below or in excess of its

limits as indicated in the technical specifications.

DURING

 

MAINTENANCE

 

AND

 

REPAIR

Maintenance, overhaul and repair work shall only be carried out by
adequately trained personnel; if required, under supervision of someone
qualified for the job.

1

Use only the correct tools for maintenance and repair work, and only
tools which are in good condition.

2

Parts shall only be replaced by genuine Atlas Copco replacement parts.

3

All maintenance work, other than routine attention, shall only be
undertaken when the unit is stopped. Steps shall be taken to prevent
inadvertent starting. In addition, a warning sign bearing a legend such as
”work in progress; do not start” shall be attached to the starting
equipment. 
On engine-driven units the battery shall be disconnected and removed or
the terminals covered by insulating caps. 
On electrically driven units the main switch shall be locked in open
position and the fuses shall be taken out. A warning sign bearing a
legend such as ”work in progress; do not supply voltage” shall be
attached to the fuse box or main switch.

4

Before dismantling any pressurized component, the compressor or
equipment shall be effectively isolated from all sources of pressure and
the entire system shall be relieved of pressure. Do not rely on non-return
valves (check valves) to isolate pressure systems. In addition, a warning
sign bearing a legend such as ”work in progress; do not open” shall be
attached to each of the outlet valves.

5

Prior to stripping an engine or other machine or undertaking major
overhaul on it, prevent all movable parts from rolling over or moving.

6

Make sure that no tools, loose parts or rags are left in or on the machine.
Never leave rags or loose clothing near the engine air intake.

7

Never use flammable solvents for cleaning (fire-risk).

8

Take safety precautions against toxic vapours of cleaning liquids.

9

Never use machine parts as a climbing aid.

10 Observe scrupulous cleanliness during maintenance and repair. Keep

away dirt, cover the parts and exposed openings with a clean cloth,
paper or tape.

11 Never weld on or perform any operation involving heat near the fuel or

oil systems. Fuel and oil tanks must be completely purged, e.g. by
steam-cleaning, before carrying out such operations. Never weld on, or
in any way modify, pressure vessels. Disconnect the alternator cables
during arc welding on the unit.

12 Support the towbar and the axle(s) securely if working underneath the

unit or when removing a wheel. Do not rely on jacks.

13 Do not remove any of, or tamper with, the sound-damping material.

Keep the material free of dirt and liquids such as fuel, oil and cleansing
agents. If any sound-damping material is damaged, replace it to prevent
the sound pressure level from increasing.

14 Use only lubricating oils and greases recommended or approved by

Atlas Copco or the machine manufacturer. Ascertain that the selected
lubricants comply with all applicable safety regulations, especially with
regard to explosion or fire-risk and the possibility of decomposition or
generation of hazardous gases. Never mix synthetic with mineral oil.

15 Protect the engine, alternator, air intake filter, electrical and regulating

components, etc., to prevent moisture ingress, e.g. when steam-cleaning.

16 When performing any operation involving heat, flames or sparks on a

machine, the surrounding components shall first be screened with non-
flammable material.

17 Never use a light source with open flame for inspecting the interior of a

machine.
