Dangers and residual risks
2.02
General Information - Safety
TI008G0001
After having carefully considered all possible risks concerning the use and maintenance of the machine,
all measures have been adopted to eliminate risks and limit dangers to exposed people.
Although the machine is equipped with safety devices, the following residual risks remain, which can be
eliminated or reduced by the relevant precaution:
• Risk of bruises, tearing, cuts during the handling of tools and/or elements.
• Risk of bruises during machine intervention.
Operation
❑ The operator should use the personal protection devices.
❑ Use the compressor only for the kind of application for which it is designed (air compression for
industrial use).
❑ Before starting, ensure that compressor is lled with oil.
❑ Please refer to Section 8 of this manual for the oil type to be used.
❑ Never operate the compressor if there is a possibility of inhaling smoke or toxic or ammable va-
pours.
❑ Never operate the compressor at higher pressures than those indicated in the id plate.
The air delivered by the compressor must not be used for breathing, although it is ltered
and puried from oil.
❑ If hoses are used to distribute the air, ensure they are properly sized and suitable for the operating
pressure, and not damaged or worn.
Please remember that rubber hoses should be replaced at regular intervals.
❑ Never remove the oil ller plug when the machine is running or there is still pressure inside the
compressor: there would be hot oil leak.
❑ Although it has an acceptable sound pressure level, the machine can produce a much higher noise
if the room is narrow and reverberating. Please note that the continuous presence of an operator
is unnecessary.
For safey against noise, in compliance with local laws in force, and if necessary, place specic warn-
ing signs near the machine and equip personnel with suitable protections.
Installation
Besides fullment of rules and regulations issued by the authorities, it is recommended to con-
sider the following:
❑ The compressor will perform most efciently if installed in a suitable, well ventilated area and far
from heat sources.
❑ Should any duct be installed for the suction and cooling of air, always use the data and recommen-
dations given in Section 4 and preferably obtain expert advice during the design stage.
❑ In case of outdoor installation (not suggested for very cold climates) it is necessary to place the
machine under a roof or covering, to protect it against weather.
❑ Be careful that no foreign materials clogg the radiator and cause rises of the operating tempera-
ture.
❑ The intake air must be clean and free from ammable vapours, which could cause res or explo-
sions.
❑ As the machine is air cooled, adequate ventilation must be ensured to prevent it from overheating
and thus avoiding the recirculation of the expelled hot air.
❑ Control and safety devices should never be tampered with.
❑ If one or more compressors are installed on a single pneumatic line, it is essential that each unit is
equipped with a detect valve.
❑ Electrical connection should be conforming to current regulations. The machines should be earth
connected and protected by a magneto-thermal switch against possible short circuits.
❑ It is essential to install a mains isolating switch upstream of the compressor.
2.03
General Information - Safety
TI008G0001
Maintenance
The person responsible for operation of the compressor should check periodically that all instructions
for operation and maintenance are followed by the operator.
WARNING !!!
Fill in the specic “Maintenance Sheet” supplied with the machine.
Only trained staff should carry out maintenance, with the compressor off and with no pressure inside the
same. Also disconnect the compressor from the pneumatic equipment.
Cut out the electricity supply by acting on the mains isolator located upstream of the compressor electric
board and indicate with a special sign that the machine MUST NOT BE RESTARTED.
WARNING !!!
An adequate cleaning of both the machine and the place where it is installed is highly
recommended.
For cleaning DO NOT USE ammable uids or products not complying with current
regulations.
In case of doubts about the compressor operation or of any of its components, it is
recommended to contact the after sales service of Ing. Enea Mattei S.p.A.
The following should be also considered:
❑ Before intervening on the machine, disconnect the electrical supply by means of the mains isolator.
In fact, the machine is equipped with an automatic start system, starting the same at any time, if
required by the compressed air system.
❑ The key for opening/closing the electric box doors should be given only to skilled personnel.
❑ Maintenance operations should be always carried out with compressor not operating.
❑ Before carrying out any job on the compressor unit, ensure through the gauge that there is no pres-
sure inside.
❑ Only use suitable tools for the kind of job.
❑ Never use solvents and ammable products to clean the machine or individual parts.
❑ Never carry out weldings or other jobs requiring considerable heat near the machine, specically
near the electrical system and the oil circuit.
❑ Do not make modications or weldings on vessels under pressure.
❑ Do not leave tools, rags or other loose items on the motor or on the compressor.
❑ The lubricating oil, especially if exhausted, may damage the skin: protect hands with gloves or spe-
cic protecting products for the skin.
❑ Do not wear clothes contaminated by lubricating oil
❑ Absolutely avoid contaminating the ground with lubricating oil.
❑ To prevent pollution, store the exhausted lubricant into suitable containers and in a safe place. For
oil disposal follow what suggested by internal rules and current regulations.
❑ In case of topping up, use the same oil as already contained in the machine.
Mixtures are harmful for both the oil and the compressor life.
❑ After any maintenance, start the machine and check that all control, stop or alarm devices are work-
ing correctly; also verify that temperature and pressure values are the correct ones.
❑ Make checks and overhauls as foreseen in this Manual, and use only original spare parts.
Failing to make checks or using non original spare parts may cause problems that jeopardize the
machine operation and the manufacturer’s warranty will be no longer valid.
