Important Safety Instructions

when you stop spraying and before you service or clean

the sprayer, remove parts, or repair leaks.

1. Turn power switch OFF. Unplug sprayer.

2. Turn Spray/Prime valve to PRIME to relieve pressure.

Turn pressure control knob left (counterclockwise) to

minimize pressure.

NOTE: Leave Spray/Prime valve in PRIME

position until you are ready to spray again.

If you suspect that the spray tip or hose is completely

clogged or that pressure has not been fully relieved after

following the steps above, VERY SLOWLY loosen the tip

guard retaining nut or hose end coupling to relieve pressure

gradually. Then loosen it completely. Clear the tip or hose

obstruction.
