OPERATION

WARNING

Pressure Relief Procedure

To reduce the risk of serious bodily injury, including in- jection; splashing in the eyes or on the skin; injury from moving parts or electric shock, always follow this pro- cedure whenever you shut off the sprayer, when checking or servicing any part of the spray system, when installing, cleaning or changing spray tips, and whenever you stop spraying.

1.Engage the trigger safety latch.

2.Turn the ON/OFF switch to OFF.

3.Unplug the power supply cord.

4.Disengage the trigger safety latch. Hold a metal part of the gun firmly to the side of a grounded metal pail, and trigger the gun to relieve pressure.

5.Engage the trigger safety latch.

6.Open the pressure drain valve, having a container ready to catch the drainage. Leave the pressure drain valve open until you are ready to operate the sprayer again.

If you suspect that the spray tip or hose is completely clogged, or that pressure has not been fully relieved af- ter following the steps above, VERY SLOWLY loosen the tip guard retaining nut or hose end coupling and re- lieve pressure gradually. Then loosen the part com- pletely. Clear the tip or hose obstruction.
