    Warning

 

The  clothing  of  whoever  operates  or  carries  out 
maintenance  on  the  machine  must  conform  to 
the  essential  safety  requirements  defined  by 
European  directive  and  the  laws  in  force  in  the 
country in which the machine is installed.

 

 
 

 

 

 

 

  Attention

 

During maintenance operations individuals must 
wear 

adequate 

clothing 

to 

prevent 

the 

occurrence of accidents. 

 
In order to avoid mechanical risks such as snagging or 
dragging, it is prohibited to wear particular objects such 
as  bracelets,  watches,  rings  or  necklaces  during  the 
working cycle and during maintenance operations. 
 

2.7. Residual risks 

The  accurate  risk  analysis  carried  out  by  the 
manufacturer  and  archived  in  the  technical  file  has 
eliminated  most  of  the  residual  risks,  which  are 
nevertheless present during the use of the machine, to 
acceptable levels. 
The manufacturer’s recommendation is to meticulously 
adhere 

to 

the 

instructions, 

procedures 

and 

recommendations contained in this manual. 
 

 

 

 

 

 

   Attention

 

It  is  strictly  prohibited  to  carry  out  any  type  of 
mechanical  or  electrical  modification  so  as  not 
to create added dangers and unforeseen risks. 
 

 

 

 

 

 

  Attention

 

During  cleaning  and  maintenance  operations 
and  during  the  work  cycle,  do  not  allow  the 
product inside the tank to come into contact with 
water or other fluids. 
 

 

 

 

 

 

  Attention

 

If  the  machine  remains  unused  for  long  periods 
of time please take note of the expiry date of the 
product  remaining  inside  the  machine.  Upon 
restarting  the  processing  only  insert  new 
chocolate  if  the  product  already  in  the  machine 
has  not  expired.  If  the  old  product  has  expired, 
proceed  to  empty  and  clean  the  machine  before 
inserting the new product. 

 

 

 

 

 

  Attention

 

Keep  the  machine  with  the  residual  chocolate 
inside the tank in an adequate environment with 
temperatures ranging from 10 °C to 25 °C. 

 
The residual risks present on the machine are: 
 

Risks during machine transportation

 

It is recommended to fasten the machine, or its parts, 
at  the  dedicated  locations    and  lift  it  with  appropriate 
means  to  the  minimum  permitted  height,  proceed  at 
low speeds and make sure that the people helping with 
the  moving  are  at  a  safe  distance  from  the  moving 
object. Before moving the machine make sure that the 
passage  is clear and  that  there  are  no  objects  placed 
on  the  machine.  It  is  important  that  the  means  of 
support  and  transportation  is  controlled  by  a  person 
qualified  for  such  a  role,  so  as  to  avoid  unforeseen 
movements which may be dangerous to the people in 
the vicinity who are helping with the moving. 
 

Risks  of  faults  to  the  circuits  of  signalling,  safety, 
protection and emergency stop

 

In  the  case  of  a  circuit  fault,  the  safety  and  signaling 
circuits,  the  anti-injury  protections  and  the  emergency 
stop  can  lose  their  effectiveness,  therefore  it  is  asked 
that their functionality is periodically checked. 
 

Identified residual risks and information plaques

 

The  manufacturer  has  placed  on  the  machine  danger 
and/or  warning  plaques,  based  on  the  residual  risks, 
with pictograms in compliance with the norm pertaining 
to the display of graphic symbols on the machine. 
The  user  should  immediately  replace  these  plaques  if 
they are not clearly legible. 

 

 

 

 

  Attention

 

It  is  expressly  forbidden  to  remove  the  safety 
and/or  warning  plaques  placed  on  the 
machine. 
The 

manufacturer 

will 

not 

take 

any 

responsibility on the  safety of the machines if 
this is not observed.
