spraying

the  Model  h7669  hVlp  spray  gun  is 
designed  to  spray  medium  to  high  solid 
materials  like  lacquers,  stains,  primers,  
multi-component paints, clear coats, acryl-
ics,  epoxies  etc.  it  is  ideal  for  auto  body 
and,  woodworking  projects  and  can  be 
used with waterborne materials.

to use your spray gun:

1.  read and follow the material manufac-

turer's instructions for spraying, mixing, 
safety, disposal, and any other instruc-
tion on the label or Material safety data 
sheet (Msds).

2.  Ensure  the  cup  is  securely  tightened 

and all other fittings are secure to avoid 
air leaks or material spills.

3.  set the inlet air pressure (the air com-

ing  to  the  spray  gun)  to  the  lowest  
pressure  recommended  in 

tool  data 

on 

page 7 or to the material manufac-

turer's recommendations.

4.  adjust the atomizing cap to vertical or 

horizontal.  see 

atomizing  cap  and 

fan adjustments on page 12 for fur-
ther explanation.

5.  Fill the cup with material.

6.  trial and error are necessary to achieve 

the  results  you  want  along  with  a  fair 
amount of practice. test your material 
flow  and  spray  pattern  on  a  piece  of 
cardboard  or  some  scrap  of  material 
similar to your project.

eXplosion  hazard!  do  not 
smoke  or  have  any  source  of  flame 
or  spark  near  spraying.  vapors  will 
explode if ignited.

respiratory hazard! always use 
respirator  rated  for  organic  vapor 
and  solvent  use  when  using  spray 
equipment.  failure  to  protect  your 
lungs can lead to respiratory illness 
and nervous system damage. 

toXic  fumes!  always  use  an 
approved  spray  booth  or  well  ven-
tilated  area  when  spraying.  never 
spray  in  an  confined  space  where 
toxic  fumes  and  flammable  vapors 
can accumulate to deadly levels.
