Disconnect the Husky Powerwasher from the power and allow the unit to cool completely.
Unscrew the connections between the hoses, spray wand and gun. Wipe out the connections with a clean, damp cloth and apply a small amount of grease that's not water-soluble on the o-rings.
Reattach the connections in a clockwise motion firmly until each connection is snug.
Turn the spray nozzle counterclockwise to remove from the wand. Wipe out the nozzle with a clean, damp cloth and flush the nozzle out with water. Reattach the nozzle to the wand firmly in a clockwise direction until snug.
Remove the water plug at the front base of the power washer to access the screen filter. Rinse the screen filter to remove debris that may be causing a leak when water passes through the filter. Replace the screen filter and attach the water plug firmly.
