Before starting a maintenance procedure the safety
officer must:
1) Clear the working area of extraneous materials
and people.
2) Make sure that the necessary tools are
conveniently available to the maintenance
technician and that they are in good condition.
3) Make sure that the lighting is sufficient and
provide, if necessary, portable low voltage lights.
4) Make sure that the maintenance technician is
equipped with the necessary approved personal
protection equipment for the specific operation
(gloves, safety glasses, shoes, etc.).
5) Make sure that the maintenance technician has
carefully read the instructions contained in this
manual and has excellent knowledge of how the
machine works.
At the end of every maintenance intervention the
following procedures need to be carried out before
restarting the machine:
6)
Carefully clean the floor in the work area,
removing any residues that may cause
slippage
7)
Lock the protective panels back into place,
check the functionality of the interlocking parts
and of the safety devices. Make sure to re-
activate
them
if
they
were
previously
deactivated
8)
Make sure that no extraneous components
have been left in the machine, especially
mechanical parts, utensils or components used
for maintenance that could cause damage to
the machine or put personnel at risk.
9)
Before switching the machine back on make
sure that all personnel are at a safety distance.
10) Before
restarting
the
processing,
the
maintenance technician must check the entire
working cycle, the functionality of the safety
mechanisms and the integrity of the fixed
protective panels.
11) before restarting the working cycle the machine
must be cleaned according to the instructions in
section 6.3.
Attention
Following every maintenance intervention it is
the Safety Officer duty to ascertain that the
machine is working properly and that all the
safety devices are present and functional.
Unless expressly required for the solution of a
breakdown, never interfere with the adjustments and
positioning of the limit microswitches; their tempering
can cause serious damage to the machine and pose
risks to the operator.
Before assembling a block always cover with a thin
layer of alimentary grade oil the internal parts and
coupled surfaces. replace all the seals and gaskets
with original parts before reassembling the
components.
Note
Before reinstalling the machine components
that have been washed with water or other
liquids, check that they are completely
dry.
Work on electrical components must only be carried
out by the electrical maintenance technician
specially trained and authorized by the Safety
Officer.
6.3. Cleaning external parts
Attention
The chocolate present inside the tank and
inside the machine must not come into
contact with water or other liquids: there is a
risk of mould formation leading to bacterial
presence.
Attention
Use appropriate personal safety equipment
while carrying out the cleaning of the machine.
Clean persistent stains with dry and soft clothes that
do not fray or use flexible bristle brushes.
If the stains are incrusted and hard to remove with
dry clothes or brushes use a liquid solvent
appropriate for use in an alimentary environment.
Avoid the use of flammable or toxic solvents.
Clean the signalling plaques with a cloth, soap and
water or any other mild liquid; avoid using chemical
solvents.
Before beginning and at the end of every
maintenance operation it will be necessary to
vacuum away the dust and other residues, recurring
to using appropriate solvents if necessary but
avoiding the use of compressed air jets which can
create zones of dirt accumulation and may cause
injury to the individuals present in the area
