Do not dilute the detergent. The detergent sprays out at low pressure only. Slide the Spray
Nozzle out for low pressure. The pressure washer will draw the detergent up through the
Detergent Suction Hose and mix the water and detergent automatically, at about a 6% deter-
gent 94% water ratio. See Figure B.

2. Turn the Power Switch (F) to the OFF position. The engine will stop.
3. Turn the Fuel Valve (D) up to the closed position.
4. Turn off the water supply faucet.
