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 tires 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.

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.
