7.

  Adjust  the  fluid  control  knob  to  start 

with a low volume of material and keep 
the  atomization  as  low  as  possible. 
You will need to use a combination of 
fluid control, inlet air pressure, air flow 
control and stroke speed to achieve the 
results you want. Spray so the material 
wets out nicely without running or sag-
ging.

8.

  Use  the  pattern  control  knob  to  adjust 

the spray fan to your desired pattern.

9. 

Keep the gun tip perpendicular,  parallel  
and  6-12"  from  the  work  at  all  times 
when  spraying,  as  shown  in 

Figure 

7

.  Do  not  allow  your  wrist  to  bend. 

This  will  cause  the  gun  to  arc  across 
the  surface  and  distribute  the  material 
unevenly,  possibly  creating  sags  and 
dry spots.

10.

  Begin  spraying  2-3  inches  before  the 

work  and  continue  to  the  end  of  the 
work.  Continue  the  motion  for  a  few 
inches  past  the  work  until  you  are 
ready for the return stroke. 

11.

  Maintain  an  even  speed  when  spray-

ing.

12.

  Overlap each stroke by 50%. This will 

ensure  even  coverage  as  shown  in 

Figure 8

. Overlapping less than 50%, 

as  shown  in  the  figure  to  the  right, 
may  lead  to  missed  spots  or  streaky 
results.

NOTICE

Tipping  the  spray  gun  may  cause 
material to spill out of the cup. Always 
hold  the  spray  gun  perpendicular  to 
the  ground  to  avoid  potential  spills 
and  feed problems.

The spray stroke should have even con-
sistency and parallel edges. If it doesn't, 
please  refer  to
