Follow these steps for safe and effective operation of your Kärcher HD 6/15 M pressure washer.

3.1 Starting the Machine

1. Ensure all connections (water, high-pressure hose, electrical) are secure.
2. Open the water tap fully.
3. Turn on the main power switch of the pressure washer.
4. Squeeze the trigger on the high-pressure gun to release any trapped air and allow water to flow through until a steady stream emerges. This primes the pump.
5. The machine is now ready for use.

3.2 Using the Easy!Force High-Pressure Gun

The easy!force high-pressure gun is designed to minimize user fatigue. It uses the reaction force of the high-pressure jet to reduce the holding force required to zero. Simply aim the nozzle at the surface to be cleaned and squeeze the trigger. Release the trigger to stop the water flow.

3.3 Cleaning Techniques

• Always start cleaning from a distance and move closer as needed to avoid damaging the surface.
• Use appropriate nozzles for different cleaning tasks. A wider spray pattern is suitable for general cleaning, while a narrower, more powerful jet is for stubborn dirt.
• For optimal results, clean in sections, overlapping slightly to ensure even coverage.
• When cleaning vehicles or delicate surfaces, avoid directing the high-pressure jet directly at tires, seals, or electrical components.

2. Turn off the main power switch on the pressure washer.
3. Turn off the water tap.
4. Squeeze the trigger on the high-pressure gun again to release any residual pressure in the system.
5. Disconnect the high-pressure hose and water supply hose.

4. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Kärcher HD 6/15 M pressure washer.

4.1 General Cleaning

• After each use, wipe down the exterior of the machine with a damp cloth.
• Ensure no dirt or debris accumulates around the air vents.

4.2 Water Inlet Filter

Regularly check and clean the water inlet filter to prevent blockages and protect the pump. Remove the filter, rinse it under running water, and reinsert it.

4.3 Frost Protection

If storing the machine in an area where temperatures may drop below freezing, drain all water from the pump and hoses to prevent damage. Run an anti-freeze solution through the pump if necessary, following manufacturer guidelines for such solutions.

4.4 Storage

Store the pressure washer in a dry, frost-free location. Coil the high-pressure hose neatly and store the gun and lance in their designated holders on the machine.
