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.

shield washer fluid is to provide proper lubrication to the internal
seals of the pump regardless of temperature or environment.

washer fluid, and 16–36" (91 cm) of garden hose with a male
hose connector attached to one end.
