6.   To avoid cross-threading, all spray gun parts should 

be screwed in hand tight initially. If the parts cannot 

easily be turned by hand, be sure that you have the 

correct parts, unscrew, realign, and try again. Never 

use excessive force in matching parts.

7.   Use only accessories identified by the manufacturer 

for the specific tool model.

parts and/or authorized parts.

9.   Use only lubricants supplied with the tool or specified 

by the manufacturer.

10. Maintain spray guns with care. Keep spray guns clean 

and oiled for best and safest performance.

11. Store the tool out of reach of children and other 

untrained persons when it is idle.

NOTE

   

 Before using desired paint in the spray gun, spray a
