17 Remember that where there is visible dust, the
existence of finer and invisible particles should also
be checked, yet the fact that dust is not visible does
not indicate that these dangerous particles are not in
the air.
18 Never use the generator beyond the limits imposed by
the technical specifications and avoid long periods
without load.
19 Never use the generator in a humid environment. Excess
humidity may deteriorate the generator insulation.
20 Do not open electric boxes, boards or other equipment
with the power on.If this cannot be avoided, for example,
for making measurements, tests or adjustments, this
procedure shall only be performed by a qualified
electrician, having the suitable tools and wearing the
necessary protections (PPE).
21 Never touch on the terminals during machine running.
22 Whenever a strange situation appears, for example
one noise, vibration, a strong smell, place the circuit
breakers in the OFF (disconnected) position and switch
off the engine.The failure shall be corrected before
starting the machine again.
23 Periodically check the cables. Damaged cables and
poor lighting of connections may cause electric shocks.
Whenever the existence of dangerous circumstances
is verified, place the circuit breakers in the OFF
(disconnected) positionand switch off the engine.
Replace the damaged wires or remedy the risk situation
before stating the machine again.Make sure that all
electric wirings are well safe.
24 Avoid overloading the equipment. The generator
is fitted with overload protection.When a protection
is activated, reduce the load before starting the machine
again.
25. If the generator was used for supporting the mains
power supply, it shall have a control system that
automatically switches off the mains when the current
is switched on.
26. Never remove the cover of the output terminals with
the machine running.Before connecting or disconnecting
wires, deactivate the load and the circuit breakers, and
make sure that the machine cannot be accidentally
started, and there is no residual voltage in the electric
circuit.
27. The use of the generator with low loads during
prolonged periods reduces the engine service life,
increases the oil consumption, and promotes the
presence of oil in the engine discharge and vent.
28 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 periodo nly e.g. for inspection
or adjustment.
Safety during maintenance and repair
work
Maintenance, opening and repair tasks shall only be
performed by qualified personnel and, if necessary, under
the supervision of someone qualified for such task.
1 Use only the suitable tools for repair and maintenance
tasks, and make sure they are in good conditions.
2 Parts shall be replaced by genuine Atlas Copco spare
parts.
3 All the maintenance work, in addition to routine
tasks, shall be performed with the machine turned
off. All the necessary measures shall be taken to prevent
any accidental start.It shall also be placed a sign with
the legend "Under maintenance, do not turn on" on
the starting equipment.
In machines fitted with diesel engine, the battery
shall be disconnected and removed, or the terminals
shall be covered with insulating caps.
In the case of electric machinery, the main circuit
breaker shall be blocked in the open position and the
fuses shall be removed.On the fuse box or on the main
circuit breaker a sign with the legend "Under
maintenance, do not switch power on" shall be placed.
4 Before opening an engine or another machine, or to
proceed to more complex repair work, lock everything,
so that the moving parts cannot rotate or move.
5 Make sure that there are no tools, loose parts or pieces
of cloth left inside the machine.Never leave pieces of
cloth or loose clothing near the engine air intake
zone.
