check the surface for damage, if no damage is found,
you can assume it is okay to continue rinsing_

7,. Start at the top of the area to be rinsed, working

down with same overlapping strokes as you used for
cleaning.,

Automatic Cool Down System

(Thermal Relief)

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 a temperature
between t25 °-155°EAt this temperature, the system
engages and cools the pump by discharging the warm

water onto the ground. This system prevents internal

damage to the pump_
