eration with the Trigger (36) fully

To set the spray pattern size specific 

to the job, use the Pattern Control

4.  After setting up a piece of scrap 

material, squeeze the Trigger (36) 

in short bursts while tuning the Fluid 

Control Knob (12) counterclockwise 

and observe the spray patterns until 

you see the pattern you want. Also, 

look at the pattern for consistency. 

Too much air may cause the spray 

to come out too fine. Reduce the air 

pressure or allow more material to 

come out by opening the Fluid Con-

trol Knob (12). If the spray appears 

too thick (you see globs of paint), 

close down the Fluid Control Knob 

slowly, checking the mixture after 

each adjustment. Use the counter nut  

next to the Fluid Control Knob to lock 

the setting in place.
