5. Operation
Once assembled and connected, you can begin operating your Kärcher Compact Pressure Washer:
- Purge Air: Before turning on the unit, squeeze the trigger on the high-pressure gun to allow water to flow through and purge any air from the system. Continue until a steady stream of water emerges.
- Start the Appliance: Turn the ON/OFF switch to the 'ON' position. The motor will start, and the pump will build pressure.
- Adjust the Spray Lance: The adjustable spray lance allows you to vary the water jet from a concentrated stream to a wide fan spray. Rotate the nozzle at the end of the lance to select the desired spray pattern for your cleaning task.
- Detergent Application: To apply detergent, fill the detergent applicator with Kärcher approved detergent. Attach the applicator to the high-pressure gun. The pressure washer will automatically draw detergent when operating at low pressure.
- Cleaning Technique: Always start cleaning from a distance and gradually move closer to the surface, observing the effect of the water jet. Avoid directing the jet at sensitive materials or surfaces.
