Pump

The manufacturer recommends using a pump protector/winterizer, such as DP80 when storing the unit for more than 30 days and/or when freezing temperatures are expected. DP80 is availabe at the store where the pressure washer was purchased. If a pump protector/ winterizer is not available, RV antifreeze or windshield washer fluid needs to be run through the pump as outlined in the steps below.

NOTE: Using a pump protector/ winterizer, RV antifreeze or wind- shield washer fluid is to provide proper lubrication to the internal seals of the pump regardless of temperature or environment.

1.Obtain a funnel, 6 oz. (170 mL) of RV antifreeze or windshield washer fluid, and 16–36" (40–91cm) of garden hose with a male hose connector attached to one end.
