(it is recommended that an RCD plug socket is used. ) If using an Extension Cable make sure it is completely unwound from the cable drum and is the correct diameter. 3. 4 Suction Mode - an added benefit of the Karcher Pressure Washer • If you are drawing water from a static water supply such as a water butt disconnect the high pressure hose from the machine. [. . . ] Spray with the required jet spray setting until no trace of detergent can be found. We recommend the following cleaning method: Step 1: Remove loose dirt by washing over the surface to be cleaned with the high pressure jet. Step 2: Spray on the detergent and leave for 1-4 minutes, so assisting the easy removal of fine dirt and associated greasy adhesions. Step 3: Finally, spray off the loosened dirt with the high pressure spray. 4. 3 Low Pressure Operation with Brush (not included) When cleaning surfaces with a grease contamination - typically car paintwork that always has a greasy traffic film covering adopt the following procedure: • Washing loose dirt away with the clean water high pressure spray. • Apply the detergent in low pressure mode by setting the bayonet fit spray lance (No. 4) to its lowest (-) setting. • Leave for 2-4 minutes for the detergent to have maximum effect. • Remove the bayonet fit spray lance and fit the Wash Brush (No. 5) to the Spray Gun (No. 3). The Wash Brush is suitable for use with a water inlet temperature into the Pressure Washer of maximum 40 °C. • With or without the pressure washer switched on, brush down the surface being cleaned, this physical agitation removes all trace of traffic film. • Finally revert to the high pressure operation with the Spray Lance and complete the wash down. 11 4. 4 End Of Operation ALWAYS REMEMBER TO RINSE YOUR PRESSURE WASHER AFTER USING DETERGENT BY HANGING THE DETERGENT SUCTION TUBE IN A CONTAINER WITH CLEAN WATER AND RUN THE PUMP FOR APPROXIMATELY ONE MINUTE IN LOW PRESSURE SETTING. In the event of a break of 5 minutes in the operation of your Karcher Pressure Washer, always switch off the pump to avoid damage due to overheating. • Switch off the pressure washer by the Power Switch (No. 12) and unplug the Mains Electric Lead (No. 9) from the socket. Release the lever and then secure the lever with the Safety Locking Device to prevent accidental opening. 5. IMPORTANT – CARE AND MAINTENANCE To ensure prolonged life and trouble-free use of your Karcher Pressure Washer we strongly recommend that you always adopt the following procedures: Water • Before use, always check the inlet filter for dirt or debris. • Visually check to see if the nozzle is blocked by dirt or grit, if so, remove the dirt from the nozzle hole with a needle and rinse with water from the front. Failure to do this will seriously damage your machine and invalidate the warranty. 12 • Connect the water supply hose and, without the lance attached, squeeze the Spray Gun lever to run water through your pressure washer until the water flow is constant. • Unless drawing water from an open water source such as a water butt, always have a minimum of 10 metres (25 feet) of uncoiled hose between the water tap and your machine. The internal diameter of the feed water hose should be 12 mm (1/2”). • Water Regulations require the use of a back-flow preventer valve at the tap end of the supply hose. Only use a full flow connector to connect the hose to the machine. Electricity • If using an electrical extension lead it must be rated at a minimum of 13 amps. • Always fully uncoil any extension lead when used. Chemicals Use of chemicals other than those recommended by Karcher could cause significant damage which may not be covered by your warranty. This allows longer detergent contact time on the surface to be cleaned. 2. 637-214 9. 300-051 6. 291-080 6. 291-079 Water Pump Kit 25 Kg Grit RM 555 (5 litre) RM 555 (6 x 1 litre) 14 6.
