If you run the engine on your pressure washer for
3-5 minutes without pressing the trigger on the spray gun,
circulating water in the pump can reach temperatures above
125°F. The system engages to cool the pump by discharging
the warm water onto the ground.
"Off" Position

injury and/or property damage.
• DO NOT open both detergent shut-off valves at the same time.
9. Apply detergent to a dry surface, starting at lower
portion of area to be washed and work upward, using
long, even, overlapping strokes.
10. Allow detergent to "soak in" for 3-5 minutes before
washing and rinsing. Reapply as needed to prevent
surface from drying. DO NOT allow detergent to dry on
(prevents streaking).
