Safety precautions for portable generators
To be read attentively and acted accordingly before towing, lifting, operating, performing maintenance or repairing the generator.
Introduction
The policy of Atlas Copco is to provide the users of their
equipment with safe, reliable and efficient products.
Factors taken into account are among others:
- the intended and predictable future use of the
products, and the environments in which they are
expected to operate,
- applicable rules, codes and regulations,
- the expected useful product life, assuming proper
service and maintenance,
- providing the manual with up-to-date information.
Before handling any product, take time to read the
relevant instruction manual. Besides giving detailed
operating instructions, it also gives specific information
about safety, preventive maintenance, etc.
Keep the manual always at the unit location, easy
accessible to the operating personnel.
See also the safety precautions of the engine and possible
other equipment, which are separately sent along or are
mentioned on the equipment or parts of the unit.
These safety precautions are general and some statements
will therefore not always apply to a particular unit.
Only people that have the right skills should be allowed
to operate, adjust, perform maintenance or repair on Atlas
Copco equipment. It is the responsibility of management
to appoint operators with the appropriate training and
skill for each category of job.
Skill level 1: Operator
An operator is trained in all aspects of operating the unit
with the push-buttons, and is trained to know the safety
aspects.
Skill level 2: Mechanical technician
A mechanical technician is trained to operate the unit the
same as the operator. In addition, the mechanical
technician is also trained to perform maintenance and
repair, as described in the instruction manual, and is
allowed to change settings of the control and safety
system. A mechanical technician does not work on live
electrical components.
Skill level 3: Electrical technician
An electrical technician is trained and has the same
qualifications as both the operator and the mechanical
technician. In addition, the electrical technician may
carry out electrical repairs within the various enclosures
of the unit. This includes work on live electrical
components.
Skill level 4: Specialist from the manufacturer
This is a skilled specialist sent by the manufacturer or its
agent to perform complex repairs or modifications to the
equipment.
In general it is recommended that not more than two
people operate the unit, more operators could lead to
unsafe operating conditions. Take necessary steps to keep
unauthorized persons away from the unit and eliminate
all possible sources of danger at the unit.
When handling, operating, overhauling and/or
performing maintenance or repair on Atlas Copco
equipment, the mechanics are expected to use safe
engineering practices and to observe all relevant local
safety requirements and ordinances. The following list is
a reminder of special safety directives and precautions
mainly applicable to Atlas Copco equipment.
Neglecting the safety precautions may endanger people
as well as environment and machinery:
- endanger people due to electrical, mechanical or
chemical influences,
- endanger the environment due to leakage of oil,
solvents or other substances,
- endanger the machinery due to function failures.
All responsibility for any damage or injury resulting from
neglecting these precautions or by non-observance of
ordinary caution and due care required in handling,
operating, maintenance or repair, also if not expressly
mentioned in this instruction manual, is disclaimed by
Atlas Copco.
The manufacturer does not accept any liability for any
damage arising from the use of non-original parts and for
modifications, additions or conversions made without the
manufacturer’s approval in writing.
If any statement in this manual does not comply with
local legislation, the stricter of the two shall be applied.
Statements in these safety precautions should not be
interpreted as suggestions, recommendations or
inducements that it should be used in violation of any
applicable laws or regulations.
General safety precautions
1 The owner is responsible for maintaining the unit in a
safe operating condition. Unit parts and accessories
must be replaced if missing or unsuitable for safe
operation.
2 The supervisor, or the responsible person, shall at all
times make sure that all instructions regarding
machinery and equipment operation and maintenance
are strictly followed and that the machines with all
accessories and safety devices, as well as the
consuming devices, are in good repair, free of
abnormal wear or abuse, and are not tampered with.
3 Whenever there is an indication or any suspicion that
an internal part of a machine is overheated, the
machine shall be stopped but no inspection covers
shall be opened before sufficient cooling time has
elapsed; this to avoid the risk of spontaneous ignition
of oil vapour when air is admitted.
4 Normal ratings (pressures, temperatures, speeds, etc.)
shall be durably marked.
5 Operate the unit only for the intended purpose and
within its rated limits (pressure, temperature, speeds,
etc.).
6 The machinery and equipment shall be kept clean, i.e.
as free as possible from oil, dust or other deposits.
7 To prevent an increase in working temperature,
inspect and clean heat transfer surfaces (cooler fins,
intercoolers, water jackets, etc.) regularly. See the
maintenance schedule.

- 7 -
8 All regulating and safety devices shall be maintained
with due care to ensure that they function properly.
They may not be put out of action.
9 Pressure and temperature gauges shall be checked
regularly with regard to their accuracy. They shall be
replaced whenever outside acceptable tolerances.
10 Safety devices shall be tested as described in the
maintenance schedule of the instruction manual to
determine that they are in good operating condition.
11 Mind the markings and information labels on the unit.
12 In the event the safety labels are damaged or
destroyed, they must be replaced to ensure operator
safety.
13 Keep the work area neat. Lack of order will increase
the risk of accidents.
14 When working on the unit, wear safety clothing.
Depending on the kind of activities these are: safety
glasses, ear protection, safety helmet (including
visor), safety gloves, protective clothing, safety shoes.
Do not wear the hair long and loose (protect long hair
with a hairnet), or wear loose clothing or jewellery.
15 Take precautions against fire. Handle fuel, oil and
anti-freeze with care because they are inflammable
substances. Do not smoke or approach with naked
flame when handling such substances. Keep a fire-
extinguisher in the vicinity.
16aPortable generators (with earthing pin):
Earth the generator as well as the load properly.
16bPortable generators IT:
Note: This generator is built to supply a sheer
alternating current IT network.
Earth the load properly.
Safety during transport and installation
To lift a unit, all loose or pivoting parts, e.g. doors and
towbar, shall first be securely fastened.
Do not attach cables, chains or ropes directly to the lifting
eye; apply a crane hook or lifting shackle meeting local
safety regulations. Never allow sharp bends in lifting
cables, chains or ropes.
Helicopter lifting is not allowed.
It is strictly forbidden to dwell or stay in the risk zone
under a lifted load. Never lift the unit over people or
residential areas. Lifting acceleration and retardation
shall be kept within safe limits.
1 Before towing the unit:
- check the towbar, the brake system and the towing eye.
Also check the coupling of the towing vehicle,
- check the towing and brake capability of the towing
vehicle,
- check that the towbar, jockey wheel or stand leg is
safely locked in the raised position,
- ascertain that the towing eye can swivel freely on the
hook,
- check that the wheels are secure and that the tyres are
in good condition and inflated correctly,
- connect the signalisation cable, check all lights and
connect the pneumatic brake couplers,
- attach the safety break-away cable or safety chain to
the towing vehicle,
- remove wheel chocks, if applied, and disengage the
parking brake.
2 To tow a unit use a towing vehicle of ample capacity.
Refer to the documentation of the towing vehicle.
3 If the unit is to be backed up by the towing vehicle,
disengage the overrun brake mechanism (if it is not an
automatic mechanism).
4 Never exceed the maximum towing speed of the unit
(mind the local regulations).
5 Place the unit on level ground and apply the parking
brake before disconnecting the unit from the towing
vehicle. Unclip the safety break-away cable or safety
chain. If the unit has no parking brake or jockey
wheel, immobilize the unit by placing chocks in front
of and/or behind the wheels. When the towbar can be
positioned vertically, the locking device must be
applied and kept in good order.
6 To lift heavy parts, a hoist of ample capacity, tested
and approved according to local safety regulations,
shall be used.
7 Lifting hooks, eyes, shackles, etc., shall never be bent
and shall only have stress in line with their design
load axis. The capacity of a lifting device diminishes
when the lifting force is applied at an angle to its load
axis.
8 For maximum safety and efficiency of the lifting
apparatus all lifting members shall be applied as near
to perpendicular as possible. If required, a lifting
beam shall be applied between hoist and load.
9 Never leave a load hanging on a hoist.
10 A hoist has to be installed in such a way that the
object will be lifted perpendicular. If that is not
possible, the necessary precautions must be taken to
prevent load-swinging, e.g. by using two hoists, each
at approximately the same angle not exceeding 30°
from the vertical.
11 Locate the unit away from walls. Take all precautions
to ensure that hot air exhausted from the engine and
driven machine cooling systems cannot be
recirculated. If such hot air is taken in by the engine or
driven machine cooling fan, this may cause
overheating of the unit; if taken in for combustion, the
engine power will be reduced.
12 Generators shall be stalled 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.
13 The electrical connections shall correspond to local
codes. The machines shall be earthed and protected
against short circuits by fuses or circuit breakers.
14 Never connect the generator outlets to an installation
which is also connected to a public mains.
15 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.
16 Before transportation of the unit, switch off all the
circuit breakers.

Safety during use and operation
1 When the unit has to operate in a fire-hazardous
environment, each engine exhaust has to be provided
with a spark arrestor to trap incendiary sparks.
2 The exhaust contains carbon monoxide which is a
lethal gas. When the unit is used in a confined space,
conduct the engine exhaust to the outside atmosphere
by a pipe of sufficient diameter; do this in such a way
that no extra back pressure is created for the engine. If
necessary, install an extractor. Observe any existing
local regulations.
Make sure that the unit has sufficient air intake for
operation. If necessary, install extra air intake ducts.
3 When operating in a dust-laden atmosphere, place the
unit so that dust is not carried towards it by the wind.
Operation in clean surroundings considerably extends
the intervals for cleaning the air intake filters and the
cores of the coolers.
4 Never remove a filler cap of the cooling water system
of a hot engine. Wait until the engine has sufficiently
cooled down.
5 Never refill fuel while the unit is running, unless
otherwise stated in the Atlas Copco Instruction Book
(AIB). Keep fuel away from hot parts such as air
outlet pipes or the engine exhaust. Do not smoke
when fuelling. When fuelling from an automatic
pump, an earthing cable should be connected to the
unit to discharge static electricity. Never spill nor
leave oil, fuel, coolant or cleansing agent in or around
the unit.
6 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.
7 Periodically carry out maintenance works according
to the maintenance schedule.
8 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.
9 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.
10 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.
11 Never operate the unit in surroundings where there is
a possibility of taking in flammable or toxic fumes.
12 If the working process produces fumes, dust or
vibration hazards, etc., take the necessary steps to
eliminate the risk of personnel injury.
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. 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

- 9 -
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.
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.
18 Maintenance and repair work should be recorded in an
operator’s logbook for all machinery. Frequency and
nature of repairs can reveal unsafe conditions.
19 When hot parts have to be handled, e.g. shrink fitting,
special heat-resistant gloves shall be used and, if
required, other body protection shall be applied.
20 When using cartridge type breathing filter equipment,
ascertain that the correct type of cartridge is used and
that its useful service life is not surpassed.

- 10 -
21 Make sure that oil, solvents and other substances
likely to pollute the environment are properly
disposed of.
22 Before clearing the generator for use after
maintenance or overhaul, submit it to a testrun, check
that the AC power performance is correct and that the
control and shutdown devices function correctly.
Tool applications safety
Apply the proper tool for each job. With the knowledge
of correct tool use and knowing the limitations of tools,
along with some common sense, many accidents can be
prevented.
Special service tools are available for specific jobs and
should be used when recommended. The use of these
tools will save time and prevent damage to parts.
Battery safety precautions
Batteries
When servicing batteries, always wear protecting
clothing and glasses.
1 The electrolyte in batteries is a sulphuric acid solution
which is fatal if it hits your eyes, and which can cause
burns if it contacts your skin. Therefore, be careful
when handling batteries, e.g. when checking the
charge condition.
2 Install a sign prohibiting fire, open flame and smoking
at the post where batteries are being charged.
3 When batteries are being charged, an explosive gas
mixture forms in the cells and might escape through
the vent holes in the plugs.
Thus an explosive atmosphere may form around the
battery if ventilation is poor, and can remain in and
around the battery for several hours after it has been
charged. Therefore:
- never smoke near batteries being, or having recently
been, charged,
- never break live circuits at battery terminals, because a
spark usually occurs.
4 When connecting an auxiliary battery (AB) in parallel
to the unit battery (CB) with booster cables: connect
the + pole of AB to the + pole of CB, then connect the
- pole of CB to the mass of the unit. Disconnect in the
reverse order.
