Long Term / Winter Storage

During cold weather, store the pressure washer indoors and move it outdoors before starting the engine.
Long Term Storage and Freeze Protection
1.) Attach a feed tank or bucket to the water inlet (feed tank). See Installation section for Attaching a Water Feed Tank
instructions.
2.) Fill feed tank with 5 gallons of RV antifreeze.
3.) Run the pressure washer in cold mode until RV antifreeze comes out the water outlet. Make sure excess antifreeze is
disposed of safely. RV antifreeze will save the components from freeze damage and keep them lubricated.
4.) Disconnect spark plug cable. Make sure the engine start switch is OFF.
5.) Disconnect the battery and store it indoors.
Short Term Freeze Protection
1.) Drain water from feed tank.
2.) Drain water from the heat exchanger by extending the high pressure hose straight. Place the end of the hose at a
level that is below the pressure washer. Remove the spray gun from the hose. Disconnect the plumbing that
connects to the heat exchanger inlet. The water will flow out of the heating coil. This will protect the coil from freeze
damage.
3.) Open both water inlet ball valves and remove the cap from the water filter. This will drain the pump and water inlet
plumbing.
