Atlas Copco XAS96 DdG Manuel D'instructions page 7

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.
27 Never operate the generator in excess of its limits as indicated in the
technical specifications and avoid long no-load sequences.
28 Never operate the generator in a humid atmosphere. Excessive moisture
causes worsening of the generator insulation.
29 Do not open electrical cabinets, cubicles or other equipment while voltage
is supplied. If such cannot be avoided, e.g. for measurements, tests or
adjustments, have the action carried out by a qualified electrician only,
with appropriate tools, and ascertain that the required bodily protection
against electrical hazards is applied.
30 Never touch the power terminals during operation of the machine.
31 Whenever an abnormal condition arises, e.g. excessive vibration, noise,
odour, etc., switch the circuit breakers to OFF and stop the engine.
Currect the faulty condition before restarting.
32 Check the electric cables regularly. Damaged cables and insufficient
lightening of connections may cause electric shocks. Whenever damaged
wires or dangerous conditions are observed, switch the circuit breakers to
OFF and stop the engine. Replace the damaged wires or correct the
dangerous condition before restarting. Make sure that all electric
connections are securely tightened.
33 Avoid overloading the generator. The generator is provided with circuit
breakers for overload protection. When a breaker has tripped, reduce the
concerned load before restarting.
34 If the generator is used as stand-by for the mains supply, it must not be
operated without control system which automatically disconnects the
generator from the mains when the mains supply is restored.
35 Never remove the cover of the output terminals during operation. Before
connecting or disconnecting wires, switch off the load and the circuit
breakers, stop the machine and make sure that the machine cannot be
started inadvertently or there is any residual voltage on the power circuit.
36 Running the generator at low load for long periods will reduce the
lifetime of the engine.
1.5 S
AFETY 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
Ówork in progress; do not startÓ 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 Ówork in progress; do not supply voltageÓ 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 Ówork in progress; do not openÓ 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.
