To start your Karcher HDS 1.7 12 U Ed, first connect it to a water supply and power source. Turn on the water supply, switch on the machine using the main power switch, and then press the start button. Ensure that all connections are secure before starting.
If the machine does not start, check if the power cord is properly connected and the circuit breaker is not tripped. Also, ensure that the water supply is turned on and the pressure is adequate. If the problem persists, consult the user manual or contact customer support.
Ensure that the water inlet filter is clean and not blocked. Check the hose for any kinks or leaks. Make sure that the water supply is providing adequate pressure. If the issue continues, inspect the nozzle for clogs and clean it if necessary.
Regular maintenance includes cleaning the water inlet filter, checking the oil level, inspecting hoses and connections for wear or damage, and descaling the heating coil as needed. Refer to the maintenance section of your user manual for detailed instructions.
To descale the heating coil, use a recommended descaling agent. Follow the instructions provided with the product. Typically, you'll need to circulate the solution through the system, let it sit for a designated time, and then flush it with clean water. Ensure the machine is turned off and cool before starting.
If the machine is overheating, ensure that there is adequate ventilation around it. Check the cooling air filter for blockages and clean it if necessary. Also, verify that the water flow is consistent and the machine is not being used beyond its duty cycle.
Check the fuel level and ensure that the fuel valve is open. Inspect the ignition electrodes for damage or misalignment. Also, verify that the safety devices are not engaged and that the machine has proper ventilation. If the issue persists, consult a technician.
To store the machine during winter, ensure it is completely drained of water to prevent freezing. Clean all components and disconnect the hoses. Store it in a dry, frost-free location. Consider using a protective cover to keep dust and debris away.
Use only diesel fuel or heating oil as specified in the user manual. Avoid using biodiesel or any fuel with additives that could damage the burner. Always ensure that the fuel is clean and free of contaminants.
The oil should be changed after the first 50 hours of operation, and subsequently every 500 hours or annually, whichever comes first. Always use the recommended oil type as specified in the user manual.
