18. During operations involving either heat, flames or sparks in a machine, the surrounding components
must be protected with non-inflammable material.
19. Never use a live flame luminous source to inspect the inside of a machine, pressure container etc.
20. Before dismantling a compressor, engine or other machine or before beginning an overhaul
operation ,avoid moving mobile parts weighting over 15 kg.
21. Once the repairs are complete ensure that no tools, cloths or components have been left inside or on
top of the machine, engine or drive elements.
PRECAUTIONS DURING USE AND FUNCTION
1. The operator must avoid compressed air outlets as the force and the speed of the air may cause
injury to those in direct contact with the air jet.
2. It is however
totally prohibited
to operate the machine in closed environments in which vapours or
corrosive or explosive gas mixtures exist.
3. The machine has been designed and constructed to work with bonnet lowered and therefore it
must
not
be kept raised with the engine running, because as well as generating high noise levels which
are harmful it would also jeopardize the necessary internal ventilation that is essential to ensure
correct compressor function.
4.
Machine operation with doors open is forbidden
: certain moving parts may cause personal injury.
5. The cooling fan is controlled by a thermostat and is therefore automatically operated: never remove
the protective grating!
Should it be necessary to replace the fan, undertake replacement work by disconnecting the
machine from the electricity supply and re-connect only after re-installing the protective grating.
6. Position the machine away from the walls and take all the necessary precautions to ensure that the
hot air discharged from the engine and from the cooling systems is not recycled. Should it be
conveyed back into the engine or ventilator there is a risk of machine overheating.
7. When selecting flexible hosing to connect the machine to the tool, it is important to ensure that they
are of the correct dimensions, in terms of length, the air volume involved and the working pressure.
In fact if the piping is too small in diameter or of excessive length, there is a risk of blocking the air
flow, with a loss in charge and reduced tool performance. Never use worn, damaged or faulty hoses.
8. The hosing used to convey the compressed air from the machine to the tool, or to any other
appliance that may be applied, must have a cock at one end of the hose connection, this cock
should be kept closed when connecting the hosing to the tool and the machine in order to prevent
the risk of accidental opening of the cock itself with the consequent risk of severe wobbling of the
hosing itself, and even a risk of personal injury. Before disconnecting any piping, always make sure
that there is no internal pressure.
9. Protect the ears using suitable ear-muffs, when noise output exceeds 85 dB (A). Avoid exposure to
these noise levels for extended periods of time.
SAFETY DURING MAINTENANCE AND REPAIR OPERATIONS
Maintenance and repair operations are to be undertaken solely by adequately trained staff, supervised by a
specifically trained technician in the field if necessary.
1.
Use only the tools specifically suited to maintenance and repair operations.
2.
Use only original spares.
3.
All the standard maintenance operations aside from those of normal surveillance, are to be
undertaken only when the compressor it at a standstill. Concrete precautions should be taken to
ensure that the unit cannot be started up accidentally.
4.
Before dismantling any component under pressure, isolate the unit in an appropriate manner against
all pressure sources and discharge the pressure from the entire system.
5.
Always ensure that no parts, cloths or tools have been left inside or on top of the unit.
6.
Do not remove or tamper with the sound-proofing material.
7.
Always be sure to replace all the parts removed during maintenance operations.
