Tools that may be needed: socket or spark plug wrench, 1/2 oz. engine oil, fuel stabilizer (optional), clean rag, funnel, 12" – 14" length of garden hose or equivalent, 1-1/2 – 2 cups of RV antifreeze.


Steps to take:


  1. Remove fuel from the gas tank and run the pressure washer in a normal operating mode until the engine stops from lack of fuel.


NOTE: Normal operating mode means that the water supply is connected, water is on, high-pressure hose and gun are connected and gun trigger is squeezed so water is coming out of the gun.


  1. Stop the engine, turn off the water supply, and squeeze the gun trigger to release pressure in the hose.


  1. Disconnect the water supply and high-pressure hoses from the pump and shake water from each. Hold the gun and lance in vertical position and squeeze the trigger to drain water.


  1. Disconnect the spark plug wire and remove spark plug. Pour 1/2 oz. of engine oil into the spark plug hole.


WARNING: Never pull the starter cord on the engine when the spark plug is removed unless the spark plug hole is covered. Fuel vapor from the hole can ignite by a spark.


  1. Place a clean rag over the spark plug hole and slowly pull the rope several times to distribute oil.


  1. For winter storage continue: Insert 12" – 14" piece of garden hose into pump inlet.


  1. Place funnel in the other end of the garden hose.


NOTE:  Read the manufacturer’s instructions for safe handling and disposal of RV antifreeze.


  1. Pour approximately 1-1/2 – 2 cups of RV antifreeze into the funnel.


  1. Pull the starter cord several times until the RV antifreeze comes out of the pump outlet through the hose, gun and lance outlet connection.


  1. Disconnect the high-pressure hose from the gun and drain the hose. Hold the gun and lance in a vertical position and squeeze the trigger to drain the water out.


  1. It is always a good idea to store gun/lance/hose in a heated area.
