uniform finish, lap each strok­e over the preceding strok­e, 
mak­ing sure the spray is smooth and wet.

Using  the  lowest  possible  atomizing  air  pressure  will  
reduce overspray and provide maximum efficiency.

Proper  handling  of  the  gun  is  essential  for  obtaining  a 
good finish. The gun should be held at a right angle to 
the  surface  being  covered,  and  moved  parallel  with  it. 
For precise control of the gun and material, the trigger 
should be released before the end of the strok­e. 

Hold the gun from  6 to 12 inches away from the surface 
depending  on  material  and  atomizing  pressure.  For  a

1. Submerge the front end of the gun in solvent just until  
  the fluid connection is covered.
2. Paint that has built up on the gun should be removed  
  using a bristle brush and solvent.
. Never  submerge  all  of  the  spray  gun  in  solvent  
  because:
  •  This  will  dissolve  the  lubricant  in  the  leather  
    pack­ings and on wear surfaces, causing them to dry  
    out  and  resulting  in  difficult  operation  and  
    faster wear.
  •  Air  passages  in  the  gun  will  become  clogged  with  
    dirty solvent.
4. Using  a  rag  moistened  with  solvent,  wipe  down  the  
  outside of the gun.
5. Oil  gun  daily.  Use  a  drop  of  lightweight  machine  
  oil on:
  A. fluid needle pack­ing
  B.  air valve pack­ing
  C.  trigger pivot point

See Fig. 1 for Location of  
Above Points.

6. Caution: Do not use lubricants  
  which contain silicone. Silicone  
  may cause defects in the  
  finish application.

1. All nozzles and needles are made to exact standards.  
  They should be handled carefully.
2. To  clean  nozzles,  immerse  them  in  solvent  until  any  
  dried material is dissolved, then blow them clean. 
. Do not use metal or sharp instrument to probe any of  
  the holes in the nozzles. 
4. Air flow should occur before fluid-flow when the gun  
  is  triggered.  It  may  be  necessary  to  adjust  the  fluid  
  control screw  to mak­e sure air flows before fluid.
5. Do not alter the gun in any way.

Turn off air supply. Remove cover of cup. Empty the cup 
of material. Clean the cup and cover. Add some cleaning 
solvent to cup. Replace cup cover. Turn on air supply and 
spray  with  proper  cleaning  solvent.  Repeat  with  clean 
solvent  if  necessary.  Remove  solvent,  disconnect  gun,  
remove cup cover and clean. Wipe gun and cup with rag 
dampened with solvent.

CaUtiON…

To  avoid  cross-threading,  all  spray  gun  parts  should  be 
screwed in hand tight initially. If the parts can not easily 
be turned by hand , be sure  you have the correct parts, 
unscrew,  realign,  and  try  again.  NEVER  use  excessive 
force in matching parts.
