INSTRUCTIONS FOR USE

LM05EN002

 

B

 

GENERAL WARNINGS 

 

Carefully read the manual before starting any operation. 

 

The  machine  must  be  used  as  supplied  by  Ragazzini  S.r.l.,  following  all  the  instructions  and 
indications given in this manual. 

 

The  necessary  spare  parts  for  each  component  will  be  supplied  by  Ragazzini  S.r.l.;  otherwise  we 
decline any kind of responsibility for the product and/or for the damage it may cause. 

 

These instructions contain useful information for training and informing the operator, in order to avoid 
improper and dangerous use of the machine. 

 

The instructions must be integrated by the legislative provisions and technical standards in force; they 
do  not  replace  any  system  regulations  and  any  additional  prescriptions,  even  non-legislative,  which 
have been issued in any case for safety purposes. 

 

The  instructions  for  use  are  an  integral  part  of  the  machine;  it  is  necessary  to  keep  them  in  good 
condition, in a safe place and available to the operator (or anyone who requests them, as long as this 
person is authorised to use the machine) for the entire productive life of the machine. 

 

In the case of sale, rental, use or financial leasing of the machine, the instructions must be attached to 
the machine. 

 

The  employer  (or  their  representative)  must  have  the  operators  read  the  contents  of  these 
instructions.  

 

Unfamiliarity  with the information and  warnings given in this manual can  lead to situations of risk for 
the health and safety of operators. 

 

The  operator  must  comply  with  the  warnings  and  procedures  set  down  in  these  instructions  in  all 
stages of the machine's life cycle. 

 

Piston  pumps  are  machines  that  have  dangerous  parts,  as  they  are  live  and  equipped  with  moving 
parts. Therefore: 

o

 

Any improper use 

o

 

The removal of the protections and/or the disconnection of the protection devices 

o

 

The lack of inspections and maintenance 

Can cause serious damage to people or things. 

 

If  the  operator  detects  discrepancies  between  what  is  described  in  this  document  and  the  machine, 
they  must  immediately  inform  their  supervisor

1

  without  using  the  machine:  incorrect  or  rash 

manoeuvres can be a source of danger to the health of the operator and/or the people who are near 
the machine. 

 

The  safety  manager  must  ensure  that  the  machine  is  handled,  installed,  commissioned,  used, 
serviced and repaired exclusively by qualified personnel who must therefore have: 

o

 

Specific technical training and experience. 

o

 

Knowledge of technical standards and applicable laws. 

o

 

Knowledge of the general national, local and plant safety requirements. 

 

The  machine  is  intended  to  be  part  of  an  industrial  plant.  It  is  the  customer's  responsibility  (through 
their  Health  and  Safety  Manager)  to  guarantee  overall  safety  and  carry  out the  analysis  of  the  risks 
associated with the interfacing with other plant components. 

 

Adopt the necessary additional protection measures and related signs. 

 

The following works cannot be carried out without the authorisation of the Health and Safety Manager: 

o

 

Installation  

o

 

System modifications (configuration or intended use) 

o

 

Interventions on the electrical parts of the machine. 

 

 

                                                           

1 Supervisor: they represent the operational function, the person who has a good knowledge of the workplace and its occupants, who 
supervises the work activities and ensures that the instructions given are observed. They have duties of surveillance and supervision 
of the instructions given.
