Safety During Maintenance And Repair - Atlas Copco QAS 14 Kd S5 ESF Instruction Manual

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 reduces
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. Correct
the faulty condition before restarting.
23 Check the electric cables regularly. Damaged cables
and insufficient tightening 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
generator from the mains when the mains supply is
restored.
26 Never remove the cover of the output terminals
the generator
during operation.
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.
28 When operating the generator in Remote or Auto
mode, observe all relevant local legislation.

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.
