Using the Neilsen Jobsite CT0405 Bde6700t Diesel Generator is easy. First, make sure the generator is on a flat and stable surface. Check the fuel tank and fill it with diesel if needed. Connect your devices to the appropriate voltage output (400V/230V). Start the engine following the instructions in the engine manual. When using it, keep in mind that it has a noise level of 96dB, so you might want to use ear protection. Don't overload the generator; the rated A.C. output is 4.4kW, and the max is 4.8kW. For maintenance, regularly check the engine oil level, air filter, and spark plug. Also, clean the generator after use to keep it in good condition. If you have any problems, refer to the product manual.
