When  working  with  the  gun,  it  is  recommended  that  the  operator  wear  suitable  clothing  and 
elements of personal protection, including, without limitation, gloves, protective  goggles, safety 
footwear  and  face  masks.    Use  breathing  equipment  when  working  with  the  gun  in  enclosed 
spaces  or  in  areas  with  insufficient  ventilation.    The  introduction  and  follow-up  of  safety 
measures must not be limited to those described in this manual.  Before starting up the gun, a 
comprehensive analysis must be made of the risks derived from the products to be dispensed, 
the type of application and the working environment. 
 

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

Deal with the waste caused according to current regulations. 

To avoid damage caused by the impact of pressurized fluids, do not open 
any  connection  or  perform  maintenance  work  on  components  subject  to 
pressure until the pressure has been completely eliminated. 

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

The  equipment  includes  components  that  reach  high  temperatures  and 
can  cause  burns.    Hot  parts  of  the  equipment  must  not  be  handled  or 
touched until they have cooled completely. 

To  prevent  serious  injury  through  crushing  or  amputation,  do  not  work 
with  the  equipment  without  the  safety  guards  installed  on  the  moving 
parts.  Make sure that all the safety guards are correctly reinstalled at the 
end of the repair or maintenance work of the equipment
