SECTION 5: MAINTENANCE

Cleaning

Proper cleaning is the best way to ensure 
trouble  free  performance  from  your  spray 
gun. If your gun is not thoroughly cleaned, 
damage  and  poor  spraying  will  result. 
Problems caused by improper cleaning will 
not be covered by the warranty. Clean the 
spray gun immediately after each use.

To clean your spray gun:

1. 

Spray  a  small  amount  of  solvent 
through the spray gun.

 
 

Note: 

Check with local laws regarding 

this  practice.  If  you  are  spraying  on  a 
regular  basis,  spraying  solvents  into 
the  air  may  be  illegal.  A  cabinet  style 
spray gun cleaner may be required.

 

2.

 

Disconnect  the  gun  from  the  com-
pressed air!

3. 

Unscrew the cup.

4. 

Disassemble  the  gun  by  unscrewing 
the  fluid  control  knob,  removing  the 
spring and needle.

5.

  Unscrew  the  atomizing  cap  with  your 

fingers  and  the  fluid  tip  with  the  ser-
vice  wrench.  The  fully  disassembled  
gun should look like 

Figure 9

.

6.

  Rinse  these  parts  thoroughly  in  sol-

vent  then  dry  with  compressed  air  or 
let air dry.

 

Note:

 

If the small holes in the atomiz-

ing cap become blocked, soak in clean 
solvent.  If  the  blockage  still  exists, 
clear the blockage with a small needle, 
taking  great  care  to  not  enlarge  or 
damage the hole. Damage to the hole 
will create a disrupted spray pattern.

7.

  Use the cleaning brush with solvent to 

clean  the  inner  orifice  and  other  hard 
to  reach  areas  on  the  outside  of  the 
spray gun body.

8.

  Wipe  the  rest  of  the  gun  body  with  a 

shop towel and dry.

NOTICE

DO  NOT  soak  the  spray  gun  body  in 
solvent.  Prolonged  exposure  to  sol-
vent will rapidly deteriorate the spray 
gun washers and seals. Ignoring this  
notice will void your warranty.

EXPLOSION  HAZARD!  Chlorinated 
Solvents  like  Tricloroethane  and 
Methylene  Chloride  (methyl  chlo-
ride)  can  chemically  react  with  alu-
minum and may explode. Many parts 
in spray guns are made of aluminum. 
Read  solvent  label  carefully  before 
using solvent.
