13 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.
14 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.
15 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.
16 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.
17 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.
18 Never operate the generator in excess of its limits as indicated in the
technical specifications and avoid long no-load sequences.
19 Never operate the generator in a humid atmosphere. Excessive moisture
causes worsening of the generator insulation.
20 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.
21 Never touch the power terminals during operation of the machine.
22 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.
23 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.
24 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.
25 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.
26 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.
27 Running the generator at low load for long periods will reduce the
lifetime of the engine.
1.5 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 Prior to stripping an engine or other machine or undertaking major
overhaul on it, prevent all movable parts from rolling over or moving.
5 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.
6 Never use flammable solvents for cleaning (fire-risk).
7 Take safety precautions against toxic vapours of cleaning liquids.
8 Never use machine parts as a climbing aid.
9 Observe scrupulous cleanliness during maintenance and repair. Keep
away dirt, cover the parts and exposed openings with a clean cloth,
paper or tape.
10 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.
11 Support the towbar and the axle(s) securely if working underneath the
unit or when removing a wheel. Do not rely on jacks.
12 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.
13 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.
14 Protect the engine, alternator, air intake filter, electrical and regulating
components, etc., to prevent moisture ingress, e.g. when steam-cleaning.
15 When performing any operation involving heat, flames or sparks on a
machine, the surrounding components shall first be screened with non-
flammable material.
16 Never use a light source with open flame for inspecting the interior of a
machine.
17 When repair has been completed, the machine shall be barred over at
least one revolution for reciprocating machines, several revolutions for
rotary ones to ensure that there is no mechanical interference within the
machine or driver. Check the direction of rotation of electric motors
when starting up the machine initially and after any alteration to the
electrical connection(s) or switch gear, to check that the oil pump and
the fan function properly.
