SETTING UP TO SPRAY - CONTINUED 
 
10. 
  Turn pressure control knob (ref# 75) counter clockwise to lowest pressure 
         setting. 
11. 
  Observe and perform all pre-operation checks as required by the engine 
         manufacturer, ( Honda ). See your Honda owner’s manual. 
12.    Start engine. See Honda owner’s manual for correct procedures. 
13.   Turn prime valve knob (ref# 46) counter clockwise until fully open. Allow 
        thinner to circulate back into the siphon pail for a few minutes. Then turn the 
        prime valve knob clockwise to close the valve ( close tightly ), and direct the 
         flow to the paint hose and gun. Leave the pressure setting low. 
14.    Trigger gun into a waste container. 
15.    Remove rinse / prime fluid and pour paint through strainer bag into siphon pail. 
16.    Repeat step 13, until paint flows freely. 
         NOTE;  Never turn prime valve back to "prime" position when the unit is 
         under pressure. 
         
NOTE:  The thicker paint will require a longer time to complete the initial 
 
       prime circulation through the prime valve. Leave the valve in the prime 
        position to ensure the complete removal of all air and pre-prime fluid. Several 
         minutes may be required, particularly with thicker viscosity products. 
17.   Spray a test pattern. Begin by spraying a test pattern onto old newspaper or 
         other scrap material. 
18.    Increase the pressure, slowly at first, by turning the pressure control knob 
         clockwise. Continue increasing the pressure until the spray pattern is 
         uniformed from top to bottom, with no heavy areas. Secure pressure control 
         setting, by turning the silver lock ring (ref# 77) counter clockwise until snugly 
         against the face of the pressure control knob. If heavy areas are still visible at 
         maximum pressure setting, thin the paint with the correct thinner, according to 
         the paint manufacturer's recommendations. 
19.    Spray paint. 
Paint Straining 
 
It is recommended that all products entering the sprayer, be pre-strained to   
remove any large particles and contaminants, BEFORE they are drawn into 
the sprayer. The strainer bag should remain in place throughout the painting  
operation. This will prevent foreign matter from falling into the bucket and  
contaminating the previously strained paint. The gun filter should not be re-
lied upon to do all the paint filtration. Any dirt, grime or other undesirable 
particles which reach the gun filter have passed through the entire paint 
pump and have possibly created unnecessary damage and inconvenience. 
Always strain the paint before siphoning.
