CHAPTER 7 - Maintenance
DANGER
The personnel must wear all the required personal protection equipment to prevent accidents.
DANGER
Repair and maintenance operations on components in contact with the products must be performed by skilled and trained
personnel equipped with PPE and familiar with the MSDS (material safety data sheet).
•
Ensure maintenance tools are suitable for the use and in perfect conditions, and
fi tted with insulating grips. Ensure the insulation of cables and
wires of the test equipment do not show any signs of breakage or damage.
•
Tighten all screws and nuts with the proper tightening torques. Incorrect tightening may cause malfunctions and hazard situations.
•
Troubleshooting activities must be performed as much as possible remaining outside the protected space. Should it be required, during the
troubleshooting activity, to perform operations with powered control unit and machine, all the precautions required by safety standards must be
taken.
•
Upon completing the maintenance and troubleshooting activity, the disabled safety devices must be restored (panels, casings, guards, limit
switches, interlocks, etc.).
•
The maintenance, repair and troubleshooting activity must end by checking correct operation of the machine and all its safety devices.
DANGER
Before restarting the machine, the utmost attention must be paid and make sure that no personnel are still operating inside the
working area of the machine, indicated by danger signs.
DANGER
Before restarting the machine, check the entire system again in accordance with the start up procedures, in compliance with the
safety standards in force in the country of use of the machine.
7.3.2
WARNING NOTES
Below is a series of general warning notes to be taken into account during maintenance operations.
They represent an alert to possible deterioration or damage to the machine, equipment or other personal property belonging to the user.
•
Maximum machine reliability and minimum maintenance costs are the outcome of a scheduled maintenance program strictly followed throughout
the entire service life of the machine. Strictly comply with the established maintenance intervals.
•
Ensure machine parts are correctly lubricated. Insuffi cient or faulty lubrication may cause damage and malfunctions.
•
Prior to starting check and maintenance operations it is recommended to remove processing residues and dirt in general from the machine by
cleaning with water or air.
•
In the event of using compressed air, be especially aware of liquid sprays or fl ying dry materials and always use protective goggles and masks.
•
During disassembly, mark individual parts with an identifi cation plate, to ensure they are correctly reassembled later. After every maintenance
operation involving disconnecting wiring and/or fi xed and movable parts, check the consistency of the number/plate on fi xed part and movable
part.
•
When using the megohmmeter to check insulation of equipment, ensure all electronic control equipment (if any) is disconnected, to avoid
damaging components.
•
Always use perfectly dry air during cleaning operations and with pressure not exceeding
0.2 MPa (2 bar / 29 psi)
.
•
Always use tools in perfect repair conditions and especially designed for the operation to be performed. Using unsuitable and ineffi cient equipment
may cause severe damage.
•
Perform repair operations in clean settings and as free from dust as possible. Protect all connection openings with plastic caps and carefully cover
all the machined surfaces of the disassembled parts (with a thin layer of oil, etc.) until they are fi tted back on the machine. Requirement to be
complied with especially in the case of maintenance to the internal combustion engine, compressor, turbine, etc.
•
Replace all machine parts with original spare parts.

Clean the machine from processing material residues or dirt.
•
Thoroughly clean the machine and use specifi c rags and products.
•
Spread machined parts and moving parts with specifi c oil.
•
Clean and dry all the remaining surfaces of the machine.
•
Periodically operate the machine for short periods and check for any operation issues prior to switching on.
