LOW-OIL
Briggs & Stratton · Storm Responder 6250W Portable Generator
The engine shut down automatically due to low engine oil level. The low oil sensor is a float switch in the crankcase that shuts off the ignition system when oil drops below the minimum safe level. This prevents catastrophic engine damage from running without adequate lubrication. Check the oil level using the dipstick — add the recommended oil type (typically SAE 10W-30 or SAE 30) to bring it to the full mark. Do not overfill. The engine will not restart until the oil level is adequate. If the oil level is correct but the sensor is triggering, the generator may be on an uneven surface (tilting causes the float to read low) or the sensor itself may be faulty.
