13 After Finishing Work 13.2 Protecting the Pressure Washer in Winter Conditions Removing Water from the System To remove any remaining water from the system: ► Switch off the pressure washer, @ 11.2. ► Disconnect the pressure washer from the power supply. ► Shut off the water supply. ► Relieve system pressure. ► Remove the high-pressure hose, @ 8.2.2. ► Disconnect the water hose, @ 9. ► Drain the water out of the high-pressure hose and water hose. ► Connect the power supply cord to a properly installed electrical outlet that matches the voltage and electrical frequency stated on the pressure washer's rating plate. ► Switch on the pressure washer and let the pump run for up to 30 seconds until the water flow stops. Remaining water will be eliminated from the system. ► Switch off pressure washer and disconnect it from the power supply. NOTICE Freezing temperatures can damage components of the pressure washer. STIHL recommends storing the pressure washer indoors in a dry room where it is protected from freezing temperatures. Relieve all system pressure and make sure all water is eliminated from the pump system and hoses before storing. Protecting the Pressure Washer with Antifreeze WARNING When using antifreeze to protect your pressure washer in winter conditions, observe all warnings and instructions provided by the manufacturer to reduce the risk of environmental contamination or severe personal injury from ingestion. English If the pressure washer is to be exposed to freezing temperatures, it should be protected by a glycol-based antifreeze. The antifreeze prevents water inside the pressure washer from freezing and causing damage to the pressure washer. To protect the pressure washer with antifreeze: ► Drain the water out of the high-pressure hose. ► Disconnect the spray lance from the spray gun. ► Connect the shortest possible water hose to the pressure washer. The shorter the water hose, the less antifreeze is needed. ► Point the spray lance downward and wait until all the water has flowed out of the system. ► Pour antifreeze into a clean container. ► Connect a suction hose to the water inlet of the highpressure pump and place the other end of the hose in the container of antifreeze. ► Squeeze and hold the spray gun trigger. ► Switch on the pressure washer. ► Hold down the spray gun trigger until an even jet of antifreeze is delivered from the spray gun. Keep the spray gun into the container and follow the antifreeze supplier's instructions for avoiding environmental release. ► Press and release spray gun trigger several times. ► Switch off the pressure washer and disconnect it from the power supply. ► Detach the spray gun, high-pressure hose and water hose and allow antifreeze to run into the container. ► Collect and dispose of the antifreeze in accordance with the manufacturer's specifications and all federal, state and local laws, regulations and ordinances. NOTICE Freezing temperatures can damage components of the pressure washer. STIHL recommends storing the pressure washer indoors in a dry room where it is protected from freezing temperatures. Relieve all system pressure and make sure all water is eliminated from the pump system and hoses before storing. 0458-001-8621-A 27
