7. MAINTENANCE
7.1. MACHINE ISOLATION
Before carrying out any type of Maintenance or
Repair, it is necessary to isolate the machine from
the power supply and from all other energy sources
present.
7.2. SPECIAL PRECAUTIONS
When carrying out any maintenance or repair work,
the following recommendations should be followed:
• Before starting work, display a sign stating "MA-
CHINE UNDER MAINTENANCE" in a visible spot;
• Do not use flammable materials or solvents;
• Be careful not to pollute the environment with
coolants;
• To access the highest parts of the machine, use
the appropriate means and procedures;
• Do not climb on the machine parts, as they are not
designed to support people;
• When finished, refit and properly secure all safety
guards and devices that may have been removed
or opened.
IMPORTANT: The Manufacturer cannot be held li-
able for the failure to comply with the aforemen-
tioned recommendations nor for any other use
that is inconsistent or not mentioned in these in-
structions.
7.3. CLEANING
Before carrying out any cleaning operation, discon-
nect the device from the mains and from the energy
sources present.
Do not use corrosive cleaning products, flammable
or containing substances harmful to health.
Make sure that the parts being cleaned are complete-
ly cold.
Do not wet the internal parts to avoid damaging the
electrical and electronic components.
Do not direct any jets of compressed air directly on
the electrical and electronic components so as not to
damage them.
ATTENTION: Always use the appropriate PPE such
as gloves, mask, glasses according to current safe-
ty standards.
7.4. ROUTINE MAINTENANCE
General requirements
The machine is designed to minimise routine mainte-
nance, thus it is up to the operator to assess its condi-
tion and suitability for use.
It is recommended to stop and perform maintenance
whenever non-optimal operation is detected, so as
to ensure maximum efficiency at all times. Check the
operation of safety devices monthly. In the event of
faults or malfunction, entrust only qualified personnel
to search for the fault or call the manufacturer's tech-
nical support. Check the continuity of the earth circuit
every 2 years by performing the continuity measure-
ment according to the provisions of the CEI 44 - 5 III
Art. 19 standard. Visually check the condition of the in-
dividual parts of the machine, verifying that there is no
alteration due to sagging or deformation.
At each use of the machine, if equipped with a cooling
unit, check the coolant level and top up if necessary.
ATTENTION: Use only "SincoFluid" coolant sup-
plied on request by the manufacturer or an au-
thorised dealer.
The use of different coolants automatically voids
the warranty and excludes the manufacturer from
any liability.
ATTENTION: Allow the system to cool before pro-
ceeding with maintenance; hot surfaces can cause
serious burns.
ATTENTION: For the entire duration of mainte-
nance, it is necessary to stop the system by dis-
connecting the plug from the mains power supply
or by disconnecting the power supply from the
main panel circuit breaker, moving it to the "O"
position and locking it with a special padlock.
Always use the appropriate PPE - Personal Protective
Equipment:
• Gloves;
• Non-slip shoes;
• Suitable clothing.
Scheduled maintenance
The operations described below must be carried out
in line with the schedules indicated.
IMPORTANT: Failure to comply with the above
shall exempt the manufacturer from any liability
as specified in the Warranty.
ATTENTION: These operations, although simple,
must be performed by a Qualified or Qualified
and Authorised Technician.
