Next, you will need to connect the hoses to your Karcher pressure washer. Start by attaching the water supply hose to the water inlet on the pressure washer. Make sure it is securely fastened. Then, connect one end of the high-pressure hose to the outlet on the pressure washer and the other end to the trigger gun. Again, ensure that all connections are tight and leak-free.

Pro tip: If your pressure washer is equipped with a detergent suction tube, you can also connect it to the pressure washer at this stage if you plan to use detergent for your cleaning tasks.

Step 3: Turning on the pressure washer

Once all the hoses are properly connected, you can now turn on the Karcher pressure washer. Start by ensuring that the engine switch or power switch is in the “OFF” position. Some models may have a fuel valve that needs to be turned on if your pressure washer is powered by a gasoline engine. Then, move the engine switch or power switch to the “ON” position.

Pro tip: If your pressure washer has a choke, you may need to adjust it according to the manufacturer’s instructions before starting the engine.

Step 4: Starting the engine

To start the engine, follow the specific instructions provided by the manufacturer for your Karcher pressure washer model. Usually, this involves pulling the starter cord or using an electric starter if your model is equipped with one. Once the engine starts, let it warm up for a few moments before proceeding.

Pro tip: Always consult the user manual for your specific Karcher pressure washer model for detailed instructions on starting and operating the machine safely and effectively.
