Safety Precautions For Qas Generators; Maintenance Precautions - Atlas Copco Qas 58Jd Manuel D'instructions

SAFETY PRECAUTIONS FOR QAS
GENERATORS
Everyone who uses or maintains Atlas Copco equipment is expected to read
the following safety precautions and act accordingly before installing, operating
or repairing the generators.
The operator must employ safe working practices and observe all relevant local
safety requirements.
The owner is responsible for maintaining the unit in a safe operating condition.
Parts and accessories shall be replaced if unsuitable for safe operation.
Authorized, competent personnel shall only carry out installation, operation,
maintenance and repair.
Any modification to the unit shall be performed in agreement with and after
written approval from Atlas Copco and under supervision of authorized,
competent personnel.
If any statement in this book, especially with regard to safety, does not
comply with local legislation, the stricter of the two shall apply.
Ignoring these safety precautions may result in injury or death of the
operator and/or people in the vicinity.
In addition to normal safety rules, which must be observed with generators, the
following safety precautions listed hereafter are stressed.
INSTALLATION PRECAUTIONS
1. Generators shall be lifted only with adequate equipment in conformity
with local safety rules. Loose or pivoting parts shall be securely fastened
before lifting. It is forbidden to stay in the risk zone under a lifted load.
Lifting acceleration and retardation shall be kept within safe limits.
2. The aspirated air shall be free from flammable or toxic fumes e.g. paint
solvents that can lead to internal fire or explosion.
3. Generators shall be installed on an even, solid floor, in a clean location
with sufficient ventilation. If the floor is not level or can vary in inclination,
consult Atlas Copco. If the unit is installed on a trailer, immobilize the
trailer and chock the wheels.
4. The engine exhaust is a lethal gas. Do not operate the unit non-ventilated
a confined, non-ventilated room.
5. Never remove or tamper with the safety devices, guards, or insulation
fitted on the machine.
6. The electrical connections shall correspond to local codes. The machines
shall be grounded and protected against short circuits by fuses or circuit
breakers.
7. Damaged cables and insufficient tightening of connections may cause
electric shocks. Replace damaged cables and make sure that all electric
connections are securely tightened.
OPERATION PRECUATIONS
1. Operate the unit as described in the instruction book to ensure safe
operation.
2. Never operate the generator in excess of its limits as indicated in the
technical specifications and avoid long no load sequences.
3. Use caution when operating the generator in a humid atmosphere.
Excessive moisture causes deterioration of the generator insulation.
4. Never touch the power terminals during operation.
5. Keep all bodywork doors shut during operation. The doors may be
opened for short periods only, e.g. to carry out routine checks. Wear ear
protection.
6. People staying in environments or rooms where the sound pressure level
reaches or exceeds 90-dB (A) shall wear ear protection.
7. Periodically check that:

A: All guards are in place and securely fastened
B: All hoses, cables and/or pipes inside the generator are
in good condition, secure and not rubbing.
C: There are no leaks.
D: All fasteners are tight.
E: All electrical wiring are secure and in good order.
8. Do not remove any of, or tamper with, the sound dampening material.
9. Whenever an abnormal condition arises, e.g. excessive vibration, noise
smell etc., switch the circuit breakers to OFF and stop the engine.
Correct the faulty condition before re-starting.
10. Never refill fuel when the machine is running. Keep fuel way from hot
pipes. Never smoke while fueling. Do not spill or leave fuel, coolant or
cleaning agents in or around the unit.
11. Keep flammable material away from the machine. If required, provide a
spark arrestor to trap incendiary exhaust sparks.
12. Ground the generator as well as the load properly.
13. Check the electric cables regularly. 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 faulty
condition before re-starting.
14. Avoid overloading the generator. The generator is provided with circuit
breakers for overload protection. When a breaker has tripped, reduce the
load before re-starting.
15. If the generator is used as a standby power supply, it must not be
operated without a control system that automatically disconnects the
generator from the supply when the supply is restored.
16. Never remove the cover of the output terminals during operation. Before
connecting or disconnecting wires, switch off the load and circuit
breakers, stop the machine and make sure that the machine cannot
be started inadvertently or that there is any residual voltage on the power
circuit.
17. Never connect the generator outlets to an installation that is also conne-
cted to a public utility supply.
18. Before connecting a load, switch off the corresponding circuit breaker,
and check whether frequency, voltage, current, and power factor
comply with the ratings of the generator.
19. Running the generator at low load for long periods will reduce the lifetime
of the engine.

MAINTENANCE PRECAUTIONS

1. Use only the correct tools for maintenance and repair work.
2. Use only genuine spare parts.
3. All maintenance work, other than routine attention, shall be undertaken
when the generator is stopped and when all loads are disconnected from
the machine. Ensure that the machine cannot be started inadvertently.
4. Scrupulously observe cleanliness during maintenance and repair. Keep
dirt away by covering the parts and exposed openings with a clean cloth,
paper or tape.
5. Protect the air filter, electrical and regulating components to prevent
moisture from entering them when cleaning. Take care that the moisture
does not penetrate any component.
6. Never remove the filler cap of the cooling water system of a hot engine.
Wait until the engine has sufficiently cooled down.
7. Take safety precautions against toxic vapors of cleaning fluids.
