Daily Flushing Procedure

To reduce the risk of serious injury, including splash- ing fluid in the eyes or on the skin, or static electric discharge when flushing:

Ensure that the entire system, including flushing pails, are properly grounded.

Remove the spray tip.

Maintain metal to metal contact between the gun and the flushing pail.

Use the lowest possible pressure.

Flush the pump and gun before the fluid can dry in it.

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 11.

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 con- tainer until all the material is removed from the gun passages.
