Fuel Handling and Storage
Use only clean, fresh No. 2 diesel fuel (ASTM 2-D) above freezing and No. 1 diesel fuel (ASTM 1-D) below freezing. Ensure the fuel meets the minimum Cetane number requirement for reliable starting (at least 45). Store fuel in approved containers, away from ignition sources, in a well-ventilated area. Keep fuel away from children and unauthorized individuals. Never fill the fuel tank while the generator is running. Allow the generator to cool completely before refueling. Check for fuel leaks regularly and address any leaks immediately. Properly dispose of any spilled fuel according to local regulations. Avoid inhaling fuel fumes; they are harmful. Consult the manual for the generator’s fuel tank capacity to avoid overfilling. Using the wrong type of fuel can damage the engine and void the warranty.
Proper Disposal of Waste Materials
Used engine oil, fuel, and filters are hazardous waste and require proper disposal. Never pour used oil or fuel down drains or onto the ground. Collect used oil in a designated container, clearly labeled as used oil. Contact your local waste management authority or a designated recycling center for instructions on proper disposal of used oil and filters. They will provide guidance on acceptable disposal methods in your area. For fuel spills, use absorbent materials like kitty litter or spill pads to soak up the fuel. Dispose of the contaminated materials according to local regulations. Never burn used oil or fuel; this releases harmful pollutants into the atmosphere. Follow all local, state, and federal regulations concerning hazardous waste disposal. Improper disposal can lead to environmental damage and penalties. Always refer to the local guidelines for the proper handling and disposal of hazardous waste materials.
