Daily Flushing Procedure

NOTE:

 Flush the pump and gun before the fluid can dry 

in it.

NOTE:

 If it is available, the flushing procedure provided 

in the pump or sprayer manual should be used instead 
of this procedure.

1. Follow 

Pressure Relief Procedure

, page 12.

2. Remove the spray tip. Clean the parts.

3. Supply a compatible solvent to the gun fluid inlet.

4. Start the pump and operate it at its lowest pressure.

5. Trigger the gun into a grounded metal waste 

container until all the material is removed from the 
gun passages.

6. Follow 

Pressure Relief Procedure

, page 12.

7. Disconnect the solvent supply.

To avoid fire and explosion, always ground the entire 
system, including the gun and waste container. To 
avoid static sparking and injury from splashing, 
always flush at the lowest possible pressure and 
maintain metal to metal contact between the gun and 
flushing pail.
