Setup

Assembly

1. Attach the high-pressure hose to the designated outlet on the main unit and to the inlet on the high-pressure gun. Ensure all connections are hand-tight and secure.
2. Connect the desired lance (e.g., adjustable nozzle lance, turbo nozzle lance) to the end of the high-pressure gun. Push and twist until it clicks into place.
3. If using the foam accessory or patio brush, attach them as per their specific instructions, ensuring a secure fit.

Water Connection

The Lehmann Jukon supports multiple water sources, offering flexibility for various cleaning environments:

1. Direct Faucet Connection: Connect a standard garden hose (not included) to the water inlet on the pressure washer and to a standard outdoor water faucet. Turn on the water supply fully.
2. Suction Function (from bucket): For areas without a direct faucet, connect a suction hose (not included) to the water inlet and submerge the other end in a clean water source, such as a bucket or rain barrel. To prime the pump, hold the trigger open on the high-pressure gun until water flows steadily without air bubbles.

Power Connection

Plug the 5-meter power cable into a suitable grounded electrical outlet. Ensure the outlet is protected by a Residual Current Device (RCD) for added safety.

Operating Instructions

Starting the Unit

1. Ensure the water supply is fully connected and turned on.
2. Hold the high-pressure gun firmly and point it away from yourself, other people, and delicate objects.
3. Press the trigger on the high-pressure gun to release any trapped air and allow water to flow steadily through the system.
4. Turn on the power switch located on the main unit. The motor will start, and the pressure washer will be ready for use.

Using Accessories

The pressure washer comes with various accessories, each designed for specific cleaning needs:

• Adjustable Nozzle Lance: This versatile lance allows you to easily change the spray pattern from a concentrated, powerful jet to a wide, gentle fan spray by simply twisting the nozzle. It is ideal for general cleaning tasks.
• Turbo Nozzle Lance: Provides a powerful, rotating jet that is highly effective for removing stubborn dirt, grime, and moss from hard surfaces like concrete and stone.
• Foam Accessory: Fill this attachment with an appropriate cleaning detergent to apply a thick, even layer of foam. This is particularly useful for vehicle washing or deep cleaning tasks where detergent dwell time is beneficial.
• Patio Brush: Specifically designed for efficient and splash-free cleaning of large flat surfaces such as patios, driveways, and paths. Its rotating nozzles ensure uniform cleaning results.
• Edge Brush: Ideal for effectively cleaning edges and corners that are difficult to reach with standard nozzles.

Auto-Stop Function

The integrated auto-stop function automatically turns off the motor when the trigger on the high-pressure gun is released. The motor will restart instantly when the trigger is pressed again. This feature conserves energy, reduces operational noise, and significantly extends the lifespan of the pump.

Maintenance

After Each Use

1. Turn off the power switch on the unit and unplug it from the electrical outlet.
2. Turn off the water supply and disconnect the garden hose from the pressure washer.
3. Press the trigger on the high-pressure gun to release any remaining pressure in the system.
4. Drain all water from the pump and hoses to prevent freezing in cold weather, which can cause severe damage.
5. Clean the exterior of the unit with a damp cloth. Avoid using harsh chemicals or abrasive cleaners.
6. Regularly clean the water inlet filter to prevent blockages and ensure optimal water flow to the pump.

Storage
