Thermal Pump Protection
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 high tempera-
tures. When the water reaches this temperature, the
pump protector engages and cools the pump by
discharging the warm water onto the ground. This
thermal device prevents internal damage to the pump.
