Generac Portable Products 2700PSI High Pressure Washer
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 140145°F. When the water
reaches this temperature, the automatic cool down
system engages and cools the pump by
discharging
the warm water onto the ground.
This system
prevents internal damage to the pump.

warranty, operator must maintain high pressure
washer as instructed in this manual.
