7. Reconnect material cup and shake sprayer to move 

clean water around and clean all areas inside of cup.

8. Disconnect trigger lock and trigger sprayer for approxi-

mately 15 seconds. Engage trigger lock.

9. Discard contaminated fluid and refill with appropriate 

flushing fluid.

10. Disengage trigger lock, reverse spray tip to UNCLOG 

position, and pull trigger for 5 seconds to prime 
sprayer.

11. Put prime/spray valve DOWN to spray position. Trigger 

sprayer into waste area until no paint appears in water 
or flushing fluid.

IMPORTANT! 

For best results, do not spray more than 

one cup of water through the tip while cleaning. If more 
flushing is needed, remove the tip from the sprayer. 

12. If sprayer is not completely clean, repeat steps 4-9.

13. Engage trigger lock and put prime/spray valve UP to 

release pressure.

NOTE:

 Air vent holes or the air vent valve (as your 

model is equipped) allow air to flow into the material 
cup while spraying to prevent loss of fluid flow.

14. Remove material cup and discard used fluid. Use a 

soft brush to clean the black rubber inlet seal. If vent 
holes become clogged, use a paper clip to clear the 
holes.

15. Remove spray tip/guard assembly and clean with 

water or flushing fluid. A soft brush can be used to 
loosen and remove dried material if needed.

To avoid serious injury or damage to equipment, do not 
expose the sprayer electronics to flushing solvents. Keep 
sprayer 

at least 10 in. (25 cm)

 above the rim of the con-

tainer when flushing.

Keep spray area well-ventilated. Keep a good supply of 
fresh air moving through the area. When flushing with sol-
vents, always ground the sprayer and waste container.

NOTICE

The spray tip is permanently attached to the guard. 
Removing the spray tip from the guard will result in dam-
age to the spray tip/guard assembly. Do not store spray 
tip/guard assembly or flexible suction tube in solvent 
other than mineral spirits. Damage to parts may occur.
