GENERAL PRECAUTIONS
1. The machine owner is responsible for ensuring that the compressor is maintained
in such conditions as to ensure totally safe operation. Any parts or accessories
which fail to guarantee safe function are to be replaced.
2. Use only the oils and lubricants recommended or approved by
ROTAIR S.p.A.
and
the engine manufacturer. Ensure that the selected lubricants comply with all current
safety provisions, particularly as regards explosion or fire risks, and the hazard of
the decomposition or production of harmful gases.
3. The supervisor or the responsible party must ensure that all the instructions
concerning the function and maintenance of both machinery and equipment are
always carefully followed, and that the machines and all the related accessories
and safety instruments, comprising the entire compressed or vacuum air system
together with all the related piping, valves, connectors and hoses as well as the
expendable elements are in good conditions, that they are not excessively worn
and that they are not mishandled.
4. All maintenance, overhauling and repair operations are to be undertaken
exclusively by adequately trained staff, and supervised by a person qualified in
these types of operations if necessary.
5. In the event of suspected or evident overheating of an internal machine
component it is necessary to stop the machine, but do not open any inspection
hatch before the necessary cooling time has elapsed, to prevent the risk of the
spontaneous combustion of oil vapours on contact with incoming air.
6. Maintenance operations which do not form part of the standard maintenance
program, can only be undertaken with the machine at a complete standstill.
7. Before proceeding to disassemble any pressurized component, the compressor,
or the machine needs to be suitably isolated from all pressure sources and should
be totally exposed to the atmosphere. Each isolation valve must display a warning
sign with the wording “work in progress: do not open”.
8. Before proceeding with repair work it is necessary to take all the necessary
precautions to prevent the risk of sudden starting up. All the starter instruments
must also bear a sign with the following wording “work in progress. Do not start up”.
The battery should be detached and removed or the terminals should be covered
with insulating caps.
9. Never allow the machine or appliance to operate at beyond the established limits
(in terms of pressure, temperature, speed, etc..)
10. The machines and pneumatic appliances are to be kept clean , and free of oil, dust,
or other accumulated dirt.
11. To avoid the risk of the building up of excessive working temperatures, the heat
transfer surfaces must be regularly inspected and cleaned (including cooling fins,
coolers and the water jackets, etc). A suitable programmed cleaning frequency
should be established for each machine.
12. All the regulation and safety instruments must be maintained with the greatest care
to ensure their correct function and they must not be placed out of use.
13. Beware of damaging the safety valves and other pressure discharging instruments,
obstruction by means of varnish, oil residue or accumulated dirt is to be avoided as
it may effect the working efficiency of the instrument.
