To assemble the Karcher CMD20, start by attaching the handle to the main body using the provided screws. Then, connect the hose to the water inlet and attach the spray lance. Ensure all connections are secure before use.
If the pressure washer won't start, first check the power supply and ensure the unit is plugged in. Verify that the circuit breaker hasn't tripped. If the problem persists, examine the power cord for damage and consult the manual for further troubleshooting steps.
Routinely check and clean the water filter, inspect hoses and connections for leaks, and ensure the nozzle is free of debris. Store the unit in a dry place and protect it from freezing temperatures to maintain performance.
To store the Karcher CMD20 during winter, drain all water from the pump and hoses. Store the unit indoors in a dry environment to prevent freezing and damage. Consider using a pump saver antifreeze solution for added protection.
Pressure loss can occur due to a clogged nozzle, air in the inlet water supply, or a leak in the hose. Clean the nozzle, check all connections, and ensure there is no air trapped in the hose.
Use only Karcher-approved detergents designed for pressure washers. These detergents are formulated to work with the CMD20 and won't damage the pump or other components.
No, the Karcher CMD20 is designed for use with cold water only. Using hot water can damage the pump and other components.
First, disconnect the unit from the power source and water supply. Remove the inlet filter and rinse it under running water to remove debris. Reinstall the filter once it is clean and dry.
An uneven spray pattern may be caused by a clogged or damaged nozzle. Clean the nozzle with a needle or replace it if necessary. Check for leaks in the hose and connections.
To prevent overheating, do not run the pressure washer for extended periods without breaks. Ensure adequate water flow to the unit and avoid using it in direct sunlight for prolonged periods.
