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.

Safety 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.
