 When  working  with  the  gun,  it  is  essential  to  dress  suitably  and  use  personal  protection 
equipment,  including  the  unlimited  use  of  gloves,  protective  goggles,  safety  footwear  and  face 
masks.  Use  breathing  equipment  when  working  with  the  gun  in  enclosed  or  insufficiently 
ventilated atmospheres. The introduction and monitoring of safety measures must not be limited 
to those  described  in  this  manual.  Before  starting  to  use  the  gun,  a  rigorous  analysis  must  be 
made  of  the  risks  derived  from  the  products  to  be  dispensed,  the  type  of  application  and  the 
working environment.  

The gun forms part of the projection equipment, which is why all safety measures must be taken 
that  are  provided for the start-up use of the equipment,  in  addition to all specific measures for 
the use of the gun.  

Carefully read the safety  data sheet provided by your supplier to prevent 
any possible injury caused by incorrect handling of the raw materials and 
solvents used in the process.  

Deal with all waste caused according to current regulations. 

To  prevent  serious  damage  caused  by  the  impact  of  fluids  under 
pressure,  never  open  a  connection  or  do  maintenance  work  on 
components  subject  to  pressure  until  you  are  sure  that  all  pressure  has 
been eliminated. 

Use  suitable  protection  when  operating,  maintaining  or  simply  being  in 
the area where the equipment is working. This includes, but is not limited 
to,  the  use  of  protective  goggles,  gloves,  shoes  and  safety  clothes  and 
breathing equipment. 

The equipment includes  components which reach high temperatures and 
may  cause  burns.  The  hot  parts  of  the  unit  must  not  be  handled  or 
touched until they have completely cooled. 

To prevent serious injury caused by crushing or amputations, do not work 
with  the  equipment  if  the  safety  protections  of  the  moving  parts  are  not 
duly  installed.  Make  sure  that  all  safety  protections  are  correctly  fitted 
after carrying out repair or maintenance work on the equipment
