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. 

Empty  the  cup  and  spray  a  small 
amount of solvent through the gun.

 
 

Note: 

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  SPRAY  GUN  FROM 

AIR!

3. 

Remove the cup and cup lid.

4. 

Disassemble  the  gun  by  unscrewing 
the fluid control knob then remove the 
spring and needle.

5.

  Unscrew  the  atomizing  cap  and  the 

fluid  tip.  The  fully  disassembled  gun 
should look like 

Figure 14

.

6.

  Rinse  all  parts  thoroughly  in  solvent, 

then  dry  with  compressed  air  or  let 
air  dry.  Try  not  to  expose  O-rings  to 
solvent or they may get damaged.

 

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  gun  body  with  a  lint  free  

cloth and lubricate parts (see 

Page 11

before re-assembly.

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  1,1,1-
Tricloroethane 

and 

Methylene 

Chloride (methyl chloride) can chem-
ically react with aluminum spray gun 
parts  and  explode.  Read  solvent 
label carefully to avoid using solvent 
with these chemicals.
