2. Water Supply Connection

Connect a garden hose (not supplied) to the water inlet on the pressure washer. Ensure the water supply has sufficient flow and pressure. It is recommended to use a hose with a minimum diameter of 1/2 inch.

3. Power Supply Connection

Plug the power cord into a suitable, grounded electrical outlet. Ensure the voltage matches the specifications of the unit.

4. Detergent Application (Plug 'n' Clean)

For detergent application, simply insert the Kärcher Plug 'n' Clean detergent bottle into the designated slot on the unit. The pressure washer will automatically draw detergent when the Vario Power lance is set to the MIX position.

Figure 4: The Plug 'n' Clean system allows for easy insertion of Kärcher detergent bottles directly into the unit for convenient application.

Operating Instructions

1. Starting the Unit

1. Turn on the water supply completely.
2. Squeeze the trigger on the high-pressure gun to purge air from the system until a steady stream of water emerges.
3. Turn the pressure washer ON using the main power switch.

2. Using Spray Lances

• Vario Power Spray Lance: This lance allows you to adjust the pressure from low to high by twisting the nozzle. It also has a MIX setting for detergent application. Use lower pressure for delicate surfaces and higher pressure for tougher dirt.
• Dirt Blaster Spray Lance: This lance provides a rotating pencil jet for maximum cleaning power on stubborn dirt and hard surfaces like concrete or stone. Do not use on delicate surfaces.

3. Applying Detergent

With a Kärcher Plug 'n' Clean detergent bottle inserted, twist the Vario Power spray lance to the "MIX" position. The pressure washer will automatically draw detergent and mix it with the water. Apply detergent to the surface, allow it to dwell for a few minutes (do not let it dry), then switch the lance back to a high-pressure setting to rinse thoroughly.

4. Shutting Down

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

Maintenance

1. Cleaning the Water Filter

Regularly check and clean the water inlet filter to prevent debris from entering the pump. Remove the filter, rinse it under running water, and reinsert it.

2. Storage

Store the pressure washer in a frost-free location. Drain all water from the pump, hoses, and accessories before storing to prevent damage from freezing. The unit features integrated storage for the high-pressure gun, lances, and hose.
