Working with Detergents

The Kärcher K2 Pressure Washer allows you to use detergents to enhance cleaning effectiveness, especially for stubborn dirt and grime; However, it is crucial to follow these guidelines for safe and efficient detergent use⁚

Choose the Right Detergent⁚ Kärcher offers a range of detergents specifically formulated for pressure washers. Select the appropriate detergent based on the surface you are cleaning and the type of dirt you need to remove.
Follow Dilution Instructions⁚ Always adhere to the dilution instructions provided on the detergent bottle. Using too much detergent can reduce cleaning effectiveness and may damage the pressure washer.
Fill the Detergent Reservoir⁚ The Kärcher K2 features a detergent reservoir. Fill the reservoir with the diluted detergent according to the instructions.
Use the Detergent Setting⁚ The Kärcher K2 offers a specific setting for using detergent. Adjust the spray wand or Vario Power Nozzle to the “Mix” setting to allow the detergent to be mixed with the water jet.
Rinse Thoroughly⁚ After cleaning with detergent, always rinse the surface thoroughly with clean water to remove any detergent residue. This will prevent soap streaks and ensure a clean finish.

Remember, using detergents can be beneficial, but always prioritize safety and follow the manufacturer’s guidelines to avoid damage to your pressure washer or the surfaces you are cleaning.

Troubleshooting

While the Kärcher K2 Pressure Washer is designed for reliable performance, occasional issues may arise. Here are some common problems and solutions to help you troubleshoot⁚

No Water Pressure⁚ Check the water supply connection to ensure the tap is fully open and the water hose is not kinked or blocked. If the problem persists, inspect the water filter in the pressure washer and clean it if necessary.
Machine Pulsing⁚ If the pressure washer pulsates when on standby, check that the garden hose supplying the unit is fully uncoiled. If the pulsing occurs during use, a blockage in the accessory could be the cause. Soak the accessory in warm soapy water and rinse thoroughly under the tap to clear any blockages.

Detergent Not Dispensing⁚ Make sure the detergent reservoir is filled with the correct dilution of detergent. Check that the spray wand or Vario Power Nozzle is set to the “Mix” position to allow detergent to be dispensed.
Motor Overheating⁚ If the motor overheats, switch off the pressure washer immediately. Allow it to cool down completely before restarting. Overheating can be caused by prolonged use or insufficient ventilation. Ensure proper air circulation around the machine.
Leaking Connections⁚ Check all connections, including the hose, spray wand, and detergent reservoir, for leaks. Tighten any loose connections to prevent leaks.

Inspect and Clean the Water Filter⁚ Regularly check the water filter located at the inlet of the pressure washer. Remove and clean it with water or a mild detergent if necessary. A clogged filter can reduce water flow and pressure.
