Pressure Washer Rinsing
Automatic Cool Down System
(Thermal Relief)
If you run the engine on your pressure washer for 3-5 minutes without pressingthe trigger on the spray gun,
circulating water in the pump can reach a temperature
between 140-145°E When the water reachesthis
temperature, the automatic cool down system engagesand cools the pump by discharging the warm water onto the ground. This system prevents internal damageto the
pump.
SPECIFICATIONS
Rated Pressure ..... 2,400 psi
Flow Rate .......... 2.2 gallons per minute (gpm)
Detergent .......... Use detergent approved for
pressure washers
Water Supply Ternp. Not to Exceed 100°F
Automatic Cool .... Will cycle when water
Down System ....... reaches 140°- 145°F
_, ARNING! Be extremely careful if you must
use the pressure washer from a ladder, scaffolding or anyother relatively unstable location. Pressure in a running washer builds as you climb. When you press the trigger, the recoil from the initialspray could causeyou to fall. The high pressure spray could alsocauseyou to fall ifyou are too close to the cleaningsurface.
