NOTIcE: The manufacturer recommends using a pump protector/winterizer when
storing the unit for more than 30 days and/or when freezing temperatures are
expected. fREEZE DAMAGE Is NOT cOVERED by ThE WARRANTy.
Pump protector/winterizer is usually available at the store where the pressure
washer was purchased. If a pump protector/winterizer is not available, RV
antifreeze needs to be run through the pump as outlined in the steps below.
NOTE: Using a pump protector/winterizer or RV antifreeze is to provide proper
lubrication to the internal seals of the pump regardless of temperature or
environment.
1. Obtain a funnel, 6 ounces (170 mL) of RV
Antifreeze, and a 16" to 36" (40-91 cm)
section of garden hose with a male hose
connector attached to one end.
NOTIcE: Risk of Property Damage. Use only RV
Antifreeze. Any other antifreeze is corrosive and
can damage the pump.
2. Disconnect the spark plug wire.
