To assemble your Karcher 1.003-012.0, start by attaching the high-pressure hose to the spray gun and the unit. Connect the water supply to the inlet and ensure all connections are secure. Finally, plug the unit into a power source and test the connections for leaks.
If the pressure washer doesn't start, first check the power source and ensure the unit is plugged in. Verify that the circuit breaker hasn't tripped and that the extension cord, if used, is in good condition. If the problem persists, consult the user manual for further troubleshooting steps.
To clean the nozzle, turn off the machine and disconnect it from the power source. Remove the nozzle from the spray wand and use the included nozzle cleaning tool or a small pin to clear any blockages. Rinse the nozzle with water before reattaching it.
Regular maintenance includes checking the hose and connections for leaks, cleaning the nozzle, and inspecting the power cord for damage. Additionally, after every use, run clean water through the system to prevent detergent buildup.
Store your pressure washer in a dry, frost-free place. Disconnect all hoses and cables, and ensure the unit is completely drained of water to avoid damage from freezing.
Check for any kinks or blockages in the hose, and ensure the water supply is adequate. Inspect the inlet filter for debris and clean if necessary. If the problem continues, consult the troubleshooting section of the user manual.
To use detergent, fill the detergent tank with the recommended cleaning solution. Set the spray lance to a low-pressure setting to enable detergent application. Apply the detergent evenly, then switch back to high pressure to rinse.
Yes, but ensure the extension cord is suitable for outdoor use and has the appropriate amperage rating. The cord should be fully uncoiled to prevent overheating, and it should not exceed 25 meters in length.
Check the connections to ensure they are tight and not damaged. If the problem persists, the issue might be due to a faulty seal or gasket, and professional servicing may be required.
The oil should be replaced after the first 50 hours of use and subsequently every 300 hours or annually. Always use the oil type specified in the user manual.
